From the President’s deskAs another year winds down, ISLE completes 32 years. It has been an eventful and exciting journey. When we started this journey, Light was essentially meant to enable vision and was generally treated as a commodity. In these intervening years it has been established that light is also

crucial from health and well being, both physical as well as emotional. Lighting has also evolved as art and design. It has become interactive and personalized. And there has developed a growing awareness of the need to cut light waste and conserve energy and at the same time avoid pollution. The COP 21 in Paris last year has clearly established the urgency for reducing the adverse effects of climate change. Lighting as a major user of energy can make a substantial contribution to this effort.

In our endeavor as a Society to promote good lighting practice on a neutral platform, we closed 2015 with the highly successful Lii 2015 and Lux Pacifica conference in Kolkata and in 2016 with the Vision 2020 event in Bengaluru and brought back the newsletter as Lii Magazine and released the first issue in November. Things have started happening and several events are planned at different State Centres in the coming months. MP State Centre has planned a National seminar on “Intelligent Lighting - Emerging Trends” in Indore during January 2017. I would urge members to try and attend these events. Even with the great amount of information available on the internet, there is much to be gained from the opportunities for face to face interactions and networking discussions that these programs provide.

In 2017 we are planning to publish the 9th edition of Directory of Lighting in India. This publication will provide a comprehensive survey of Lighting in India. I would request members to take an active interest in the same.

Thanks to the initiative taken by Chennai State Centre, we are now publishing a bi-monthly magazine. I would appeal to members to participate in this publication by way of articles.The work for compilation of LED Handbook has started and I would like to thank the committee for their continued support and contribution.

Things are looking bright and I am sure 2017 will be an eventful year to cherish. I wish all our members a Happy New Year and extend my hearty Seasons Greetings

ipRGCs.Melanospin,a type of photo pigment and belonging to a family of opsins (light sensitive retinal protein)was found to form a meshwork in ipRGCs These photoreceptors were found to be sensitive to the absorption of short wavelength blue in the visible region, peaking at around 480nM (deep blue).Unlike the classical photoreceptors Rods & Cones which contribute to formation of images, the ipRGCs are non-image forming. These cells contribute to sub-conscious non-image functions. They serve as primary conduits through which photic information is relayed from the retina to non-image forming visual centers of the brain, ie direct communication to the circadian system which impacts mental and physical health. Extensive studies show that blue light after passing through our cornea and lens excites the melanospin in ipRGCs with absorption

HARMFUL EFFECTS OF BLUE LIGHT

Mr. Biswajit SenguptaM.Tech, FIE, FISLEChartered Engineer &Lighting Consultant, KolkataEmail : [email protected]

Blue Light HazardsThe optical pathway in a human eye is connected to the visual cortex (part of the brain which mediates the sense of light) via a nervous system. The nervous system comprises photoreceptors of two types – 1) Rods; 2) Cones (named on basis of the shapes of these nerve receptors). These photoreceptors, in turn, contribute to three types of visions with image forming functions, and are important for normal daily function and life quality.Scotopic (Rod) Vision-When the field luminances lie between 10^-6 cd/sqM to 10^-2 cd/sqM. This is a vision in the

darkness. The world is grey and there is no sensation of colour.

Mesopic Vision - Most important vision from a Lighting Designer’s point of view. This occurs when the field luminance is raised upwards from 10^-2 cd/sqM to 10cd/sqM. As the luminance moves upward the luminosity of red increases more strongly than that of the blues due to changing contributions of the Rods and Cone receptors. This is known as Purkinje phenomenon and is considered as an important aspect for designing effective road lighting, as it takes into account the luminance concept as well as the neurological aspects of road lighting.Photopic (Cone) Vision- This is a daylight vision, ie.when the luminance is above 10cd/sqM. Photopic vision is coloured.

A third type of photoreceptor was discovered (first in mice in 2002) and then in humans and primates in 2005. These receptors were found in mammalian retina and are called Intrinsically Photosensitive Retinal Ganglion Cells -3)

sensitivity peaking at 482nm (deep blue region). Photo reversal of bleaching (found to be most effective with blue light) takes place if the duration of exposure to this wavelength is either excessive or subject to shorter exposures over prolonged periods. It is a photochemical reaction which augments the capability of rhodospin molecules (photo pigments contained in the rods) to absorb photons in large numbers. This may lead to a cascading effect allowing the molecules to reach the critical number of photons required to induce damage in the retinal cells. In view of

crystalline nature of lens in infants and children, the penetration of blue light is high. Thus this type of retinal damage is more pronounced in infants and children.Digital devices such as smart phones, iPads, e-readers (kindles), and LED lights did not exist a decade ago. Over the last five years or so there has been a galloping increase in use of these devices. LED which contains about 35% of harmful blue light has nowadays become a dominant technology for backlighting in all digital devices. But what is more disturbing is the gradual replacement of traditional light sources by more energy efficient LED source. After discovery of blue LED at the end of twentieth century, extensive research started in order to commercialise the use of LEDs so that it can be used for general lighting. The first step was to get white light which was made possible by use of yellow phosphors. Despite great developments in phosphor technology, it has been observed that over a course of time bleaching of phosphors (particularly in high power LEDs) causes a shift in colour temperature. The blue light is not absorbed as effectively and, in turn, the blue light increases over time. Of late the city of Calcutta (Kolkata) has witnessed an invasion of LED lights in the public domain. Change to a new concept is good, but not at the cost of standard norms of good lighting practice. Here almost all streetlight poles and guard rails of flyovers are getting adorned with blue and white strips of LED. The blue is deep blue i.e. in the shorter wavelength. As a driver I have experienced a distracting and painful nature of drive through a maze of white and blue (mostly long stretches of blue) on Calcutta’s longest flyover from Race Course to Parama island at Eastern Metropolitan Bye Pass. It is not only distracting it gobbles the traditional streetlights on the flyover on which a motorist need to focus for safe driving. To add to the woes most of the strips are deep blue which adversely affect the ocular health of drivers frequenting such stretches.

LED & IOT - shaping future of lighting

LED - an evolving technologyLED, as an invention, is one of the most dynamic and most talked about light source. The demands and the expectations of the customers are ever increasing. With such requirements, the LED technology is also evolving. At times , the customer wants the most energy saving functional lighting, while at times you may expect the customer to use lighting to define a space, to lure customers, to build character into a space or ask for human centric lighting, or ask for mood lighting or even want to control lighting effects by integrating intelligence into the lighting system and at times the lighting could also be integrated with BMS !!!. Thus lighting is complex, its varied, its an ocean, its subjective, its dynamic, yet its fun, its realistic, its one of the most visible thing. One can literally play with colours of lighting and create an excellent ambience on the canvas of an open space !! creative people want to plant life into lighting by making it “smart” and “ intelligent” !!

With the invention of LEDs, a lot of the above mentioned elements have been addressed. But the expectations and the requirements from customers are going up by the days. The solid state lighting has given a new dimension to the concepts of lighting which are built on strong foundations of basic principles of lighting.In standard discreet LEDs, meant for general lighting, we have now reached a stage where in we are talking of an efficacy

Mr. Raja MukherjeeMTech, MBAVice President, Sales & MarketingSeoul Semiconductor, Gurgaon, India

of 200 lumens/ watt, may be next year, we would be talking of 220 lumens/ watt. Thus on one hand the efficacy is rising YOY, on the other hand, the prices are dropping with volumes moving northward following the fundamental laws of economies of scale.

On one hand physicists are trying to explore Silicon as an alternate substrate to sapphire On the other hand some manufacturers are trying to eliminate the LED package and getting into a new technology platform called “flip chip” thereby eliminating the wire bonding and the lead frames thus making the product more efficient and cost effective and reliable. Some scientists are working on semiconductor material which will have more uniform spectrum across the visible spectrum rather than have the high peak near the blue wavelength. Thiscoupled with proper phosphor, will also help to increase the CRI of the standard LEDs from present day CRI 80 to CRI 90. This will definitely improve the richness of the ambience and give it a more natural look. This in turn will impact the psychological and physiological parameters of human being making him/her more healthy. A lot of work is simultaneously going on in the field of “light therapy” which is giving amazing results. This is more in the UV space. This is effective because with UV LEDs the UV radiation is extremely concentrated.

The best part of this industry is that many manufacturers of LED are also working on providing a complete solution. Apart from the LED chip, one needs a AC/DC converter, we call it as driver in common parlance. This driver is an electronic equipment which is bulky, expensive, has a decay element in it ( a capacitor on LC filter ) which defines the life of entire LED system. Now imagine a cse where in you eliminate the driver completely !! You replace the driver with a small IC thus eliminating any decay element it, thereby enhancing the life and performance of the system. This concept is know as driver of board or DOB. This eliminates the driver space completely, thereby making the luminaire more compact and aesthetically

appealing . You can build intelligence into it. You can make it “talk to” wifi enabled devices thus making the application and the usage more flexible !!! Yes this is possible and such solutions are commercially available now !!

Human centric lighting & IOT Solid-state lighting is changing how we light the world, successfully displacing traditional illumination sources across every part of the global lighting market. Over the next few years, billions of sockets will be in play.

This gradual change over has initiated a new phase of LED adoption - the race to connect every socket. The stakes are high for consumers and vendors alike. Parameters like quality, proper network connectivity and access to power can make intelligent lights a perfect platform on which the immense opportunities of the Internet of Things can get initiated.

The race to own sockets is really a contest to see who will control the infrastructure of the IoT across our built environment. These intelligent, networked, sensor-based lights of the near future will form the central nervous system of every smart building. Beyond simple illumination, this “Internet of Buildings” built on top of next-generation lighting systems will forever change the way we interact with the spaces in which we live.

For eg in schools, biometric sensors will track students’ alertness, and in a subtle manner shift spectrum to automatically boost their focus any time it starts to wane. For eg if the students are feeling a little sleepy, they can get rejuvenated through an exposure to subtle blue lights. Likewise an open office space can be differentiated into various zones like isles, break out areas, meeting areas, workstations, pantry etc through lighting. Depending upon the mood of the occupants, the ambiance of the cabins can be changed by dynamic lighting !!

A BPO kind of an office, which runs 24x7, to boost up the energy levels of people

working between 12 am to 4 am, when the melatonin hormone secretion is at its peak in accordance with standard biological clocks of any normal human being there by making the person sleepy, a subtle blue light can reduce the level of melatonin and make the people more rejuvenated. A day light like simulation along the windows also helps to make people more energetic thereby increasing their productivity .!!

In todays world, with advent of LEDs, the energy efficiency of any lighting installation is a given thing. People are now talking of human centric lighting to increase the productivity by creating a “personalized feel good “ ambience. Likewise solid state lighting can have many other uses . In big warehouses for eg, beacons embedded in connected fixtures will track every movement of a fork lifter which will also be fitted with a trans-receiver and guide the driver to the exact spot of the goods. Thus locating the goods in a big warehouse will be easy and less time consuming !! at unoccupied areas the lights can be dimmed to 30 % of its level, thereby saving further energy !!

Even the lights around our home will be intelligent, learning from and responding to the steady stream of data generated by us using light to help de-stress ourselves after a long day or to perk ourselves up on a cold, dark winter morning. These scenarios are just about to take off . Intelligent lighting will be one of the first markets to realize the dream of the Internet of Things - millions (if not billions) of connected devices, silently sensing and acting on our behalf.

While the LED revolution is well accepted and understood, the story of intelligent lighting is just beginning. It all starts with the LEDs themselves. As low-voltage semiconductor devices, they have always had a natural affinity for digital control. Unlike the inherently analog and high-voltage light sources of the past, LEDs and micro controllers play well together. In the early 2000s, the first generation of solid-state lighting manufacturers took advantage of this to deliver spectacular color-changing LED lighting installations all around the world.

Since then, prices for sensors, networking chipsets and processors have reduced the incremental costs of making lights smart. The bundle of components required to make a light fixture capable of sensing its environment, acting on that information and sharing it with others has dropped in price — even more precipitously than have the LED devices themselves.

The three major factors like a) a secular shift from analog to digital, b) an explosion of low-cost supporting technologies and c) an omni present install bas, have combined to launch the era of intelligent lighting. Companies who integrate sensing, networking and control into software-based platforms will lead the way. For networking companies, intelligent lighting is an infrastructure play. Billions of connected lights will need new routing fabric, if only to handle the massive amount of new data traffic they will produce.

More connected devices than people

Sometime in 2016 / 2017, the number of connected devices will overtake the number of people on the planet for the first time. According to calculations by Gartner, the US market research company, last year around five billion devices were able to communicate via the Internet – whether smartphones or tablets, smart electricity meters, cars or factory machines. In 2016 – 17, the figure is expected to rise to between seven and eight billion. That's more than the 7.4 billion people currently living in the world. Analysts are already talking about 24 to 35 billion connected devices by 2020. But quantity brings complexity. The problem is already obvious – just look at any modern office: in addition to smoke detectors and thermostats there are often numerous presence sensors from different manufacturers for the different building services. One ensures that the light is only switched on if there is someone in the room. Another is part of the security system, a third turns down the heating and air conditioning when the last person leaves the room, and perhaps a fourth is there to control the window blinds.

Light as the omnipresent infrastructureSimplification is what is needed. How can

the level of complexity best be reduced, how can communication among the devices be harmonised? Are there no existing infrastructure systems to which the Internet of Things can simply be “integrated ”? In fact, there are. Wherever there are people, whether indoors or out on the streets, there is artificial light. In many of these luminaires there is still plenty of space for one or other digital sensor or microchip – after all, digital electronics is necessary for modern LEDs.

What's more, since the luminaires need electricity the power supply is already integrated, so to speak. No one need worry any longer about cabling the individual sensors or changing batteries. Moreover the, luminaires are mostly installed on walls or ceilings and therefore in the best places for including sensors. And communication with them and connection to the access points for the internet can be either wireless or via the data cabling that is already in place anyway. In short, the existing infrastructure for light is the ideal basis for the Internet of Things. Or to put it another way, the “Internet of Light” is the most powerful instrument for developing the Internet of Things into the useful tool that it can be in the future.

For eg a single presence sensor integrated out of sight in a luminaire is sufficient for detecting whether an office is occupied or not. This data is then stored in the Cloud – in other words on an Internet or intranet server – evaluated and forwarded to the HVAC systems, window blinds, security management system and of course to the lighting control system.It can also be used for room management, i.e. to determine how well meeting rooms, offices or communal areas are used. Building operators can use this data to optimize the usage of the building and make considerable savings in costs.

Issues to addressAlthough the future looks exiting but there are many hurdles !. We need to answer and work on the following questions before the above can be effectively used.

1 Do we have the right infrastructure to support this concept – for eg with billions

of devices getting loaded onto IOT architecture, can the current speed of internet support such installations effectively ?

2 Can some body hack the system easily ? how can that get protected , more linking of devices will lead to more information on public domain, and hence more probability of getting hacked

3 Are there any standards being set up to handle such issues ? currently its at embryonic stage !!

4 What about compatibility of protocols ? will manufacturer support open protocols ? I guess we are at an interesting and evolving stage of a new technological era. We need to see how it unfolds !!!

IntroductionIt was difficult to envision tapping the energy efficiency market in India before EESL did it. When no one imagined the energy saving potential of changing their incandescent light bulbs to LEDs, EESL was already in midst of hatching a plan to lead a movement of change in the entire nation. What change will a simple light bulb bring? The question surfaced in many minds as EESL launched the Ujala scheme in the early 2015. The Ujala programme has been the biggest example of EESL's market aggregating models to showcase sustainable development. At EESL, we were confident that the change, which started by switching to LED bulbs at South Block Prime Minister's office had the potential to herald a movement in the entire nation. Standing true, today, EESL's Ujala (Unnat Jyoti by Affordable Lighting for All) programme is the world's most unique and extensive LED distribution programme launched by the hon'ble Prime Minister of India Sh. Narendra Modi. EESL along with

EESL Simplifies Energy Efficiency

Mr. Saurabh Kumar, Managing Director, Energy Efficiency Services Ltd. (EESL)

BEE holds the mandate to foster the energy efficiency market in the country. Growing from Ujala and through a significant governmental push in domain of energy efficiency, today, EESL is running successful energy efficiency schemes like Street Light National Programme (SLNP), energy efficient fan and LED tubelight distribution programme, efficient buildings programme along with AgDSM, the agricultural pump distribution scheme. All these initiatives are catering to their specific domains to reduce the energy consumption and add to energy savings in the country.

Leading the way with UjalaWhen lighting is the first basic source of electrical consumption in households, workplaces and market, the use of energy inefficient incandescent was rampant. This traditional means of lighting wasn't only inefficient but insufficient lighting levels led people to use more filament bulbs, increasing the consumption and cost of energy manifolds. For a first significant

energy savings impact, changing of all incandescent bulbs with energy efficient LEDs was the only way out. Notably, the concept of energy efficiency is not new yet, adopting energy efficient practices has always been problematic. One of the prime reasons being that the idea of energy efficiency has been presented and viewed in a complex manner. Another bottleneck is that of a high cost factor and lack of public awareness.

Looking at the concept of energy efficiency in simple terms, it was deduced that saving a unit of electricity is way cheaper than producing one electrical unit. Simplifying our communication strategy, EESL began with awareness exercises to propagate that an LED bulb uses about 6 times less energy to give the same lighting output when compared to other traditional lighting means. The distribution of LED bulbs under Ujala was always backed by a sustained awareness and public relations exercises to bring out the huge cost savings for consumers. The problem of incandescent

bulb usage was an opportunity in disguise and EESL’s sustained efforts led to birth of world's largest and most extensive LED distribution programme, UJALA (Unnat Jyoti by Affordable Lighting for All).

Transparency mechanismsIn addition, EESL made this business model more accessible and transparent by launching the National Ujala Dashboard (www.ujala.gov.in). This dynamic web portal displays the real-time count of LED bulbs distributed in a certain region in India. The list of addresses of distribution counters with geographical tags makes it easier for people to locate their nearest kiosk.

The national Ujala Dashboard can be considered as the biggest example of transparency, which displays metrics like the total count of electrical units saved and CO2 emissions reduced against a certain count of LED bulbs distributed. Currently, the distribution of over 19 crore LED bulbs in India is resulting in annual energy savings of about 24,756 million KWh and is reducing about 2,00,52,277 tonne of CO2

emissions per year. By March 31, 2017 we expect to reach a target of distributing about 20 crore LED bulbs all across the country.

Reducing the costs through bulk procurementDue to bulk LED bulb procurement by EESL, a healthy competition rose among the manufacturers and this brought down the prices of LED bulbs in India. Interestingly, the very business model of LED distribution has successfully brought down the price of LED bulbs from Rs. 310 to Rs. 38 in a period little over a year. The earlier costly LED bulbs are now available at an extremely cheaper price due to this massive government intervention. The push through EESL’s initiatives transformed the LED market in India, and looking at the growing demand, many more indigenous LED blub manufacturers have emerged. Usage of LED bulbs is now a common sight in the country. The glaring yellow light has now changed to the cool white light of Ujala.

Realizing the potential of untapped modelsWhile the LED bulb has become a symbol

of energy efficiency and has paved the way for varied market aggregating models for scaling up energy efficiency in India, EESL shoulders initiatives like the LED tube lights distribution programme and the energy efficient fan distribution programme on the lines of Ujala. As the lighting industry in India has already been growing at 7.5% annually, the tube light scheme is an effort to meet the ever-growing demand and diverge from distribution of LED bulbs.

These tube-lights are being provided to consumers at Rs. 230 against a retail price of over Rs. 400-500. Notably, just like Ujala LED bulb, the price of LED tube lights is also expected to further drop down. Further, the energy efficient fan distribution scheme of EESL has a promising design. From an understanding that penetration of air-conditioners in Indian market is less than 10%, the cooling requirements in India are time being met by the ceiling fans. While, the fans in the Indian market are sold at an annual growth rate of 6%, EESL has started its efficient fans programme to tap this market as well. Here, EESL plans to replace over 35 crore inefficient fans with

BEE 5 star labeled energy efficient fans by the year 2018. Currently, the scope of Ujala scheme has expanded and distribution of energy efficient fans as well as LED tubelights is being done under the same banner of Ujala.

Learning from past : A retrospective view

EESL is also in a process of designing a programme to distribute super-efficient air-conditioners, which will be about 30% more efficient than the ones being sold in the market. This programme will not only enhance the adoption of super-efficient cooling technologies but will also bring down the cost of using an air-conditioner in India.

The country where air-conditioner is most often seen as a luxury will now begin to be understood as a basic necessity. The journey that started from a change of a single light bulb, has today exhibited its full potential. The recent and instant success of EESL has shown the world that viable demand based business models to promote energy efficiency is a possibility. Currently,

we're the nation's foremost company to hold and execute energy efficient programmes in India. The journey is unstoppable and we're expanding to other nations with commencement of an International Relations Group (IRG). This group, consisting of experts, is aggressively working to replicate the company's success

in other nations having similar business eco-systems as that of India. EESL in its approach is continually on a look out for new ideas to redefine the energy efficiency space.

Dr. Amardeep M.Dugar awarded first place at the IndiaInternational Science Festival 2016 - Young ScientistsConclave, New Delhi, 9-11 December 2016.

Dr. Amardeep M.DugarIALD, IES, SLLFounder & PrincipalLighting Research & Design

The India International Science Festival (IISF) is Government of India undertaking to develop and widen the spectrum of scientific temper in India and abroad. Its Young Scientists’ Conclave (YSC) aims to display India's contribution in the field of science and technology, and motivate young scientists to find solutions to the burning issues of our society. Among the many themes discussed at the YSC was the Smart Cities Mission, which is a globally collaborated urban renewal and retrofitting program by the Government of India. It is a mission to develop over 100 citizen-friendly and sustainable cities across India.

My presentation, which was awarded the first place at the IISF2016-YSC, New Delhi (9-11 December 2016) highlighted the importance of lighting design in improving the vitality of smart cities. It uses academic research to identify best practice case studies on urban lighting for the development planning for smart cities. Three fundamental questions were asked as part of this research: What qualities of urban lighting are critical to establish inviting public realms within smart cities? How should urban-lit elements within smart cities be perceived and interpreted by people so as to be termed as smart cities?

What recommendations can be offered for the development and coordination of urban lighting masterplans for smart cities?

Basic urban lighting strategies were identified by reviewing and analysing urban lighting policies of well-lit cities around the world, and systematically observing urban nighttime environments within these cities. Eight common themes emerged from this review and analysis namely: 1. Identity and Heritage - establishing an urban identity by illuminating perceptible or latent heritage components or characteristics.

2. Image and Elements - creating an image by illuminating key urban elements.

3. Environmental Considerations - exploring and implementing smart and sustainable luminaire technologies.

4. Shadow, Darkness and Mystery - recognizing the benefits and opportunities of contrasting dark and illuminated spaces.

5. Illumination Levels, Skyglow, Over-lighting and Glare - recognizing and reducing the negative impacts of over illumination.

6. Colour, Sound, Motion and Art - exploring multi-media tools to enhance short- and long-term lighting installations.

7. Safety and Connectivity - increasing the perceived safety and ease of travel through connected lighting.

8. Collaboration, Innovation, Research and Monitoring - furthering the urban lighting field by engaging with stakeholders, monitoring existing lighting projects and exploring future possibilities.

The results show that by instituting detailed design objectives for urban lighting at the planning stage coupled with thorough monitoring of existing installations to understand where improvements can be made, increases the likelihood of successfully designing smart cities.

CEPSA FLAG STATION, ADANEROSpanish petrol company CEPSA approached AUREOLIGHTING seeking a design for its newest flag stations. The company provided the lighting designer with four outsize goals: simplicity, elegance, sustainability, and future-focus. The result? A light, semi-transparent canopy and a simple red box to transmit the company’s core values.

To show simplicity, the team chose just one product model and applied it in the two brand colors, red and white. These sources are high power output LED, and are connected to a sophisticated control system. Red linear luminaires highlight the “balloons” of the canopy; white linear downlights provide general illumination to the car park; and white oval recessed linear diffused luminaires provide task lighting for the pumps area at night.

“This project illustrates an excellent use of color, which is indeed a rare thing,” one judge wrote. “It stands for a ‘clean’ concept with two separate levels: the canopy and the ground. The colored lighting adds a stunning appearance to the upper, while the white lighting facilitates the commercial use at the ground level.”

For evidence of elegance, the designers chose to completely integrate all luminaires into the architecture. White light provides general lighting throughout the project, while red light allows for color branding of the canopy and to allow other details - such as the shop - to pop out. At night, the red volumes capture a driver’s attention while passing by; but in the space, white light allows for functionality and reduces eyestrain.

The judges were impressed with the sustainable choices made by the lighting designers, far beyond just the choice of LEDs. A control system dims the lights when fewer cars populate the parking area; When a car arrives, the white lamp levels increase. Windmills located physically close to each station provide partial power, and because all white lamps are aimed down and all red lamps are aimed horizontally, no light trespass pollutes the upper atmosphere.

“This is a precisely detailed, technically clean solution with a well - considered use of color in support of the brand’s identity,” one judge commented. “I applaud the decisive - if somewhat ironic - commitment to environmental considerations.”

Finally, the futuristic elements of the design are provided largely by the ethylene tetrafluoroethylene (ETFE) balloons of the canopy, which appear open and airy when unlit and acquire a solid appearance when shot through with red. Truly a flag station for a space age.

Illumination - Beyond lm/w

Absract- In year 2002, researchers discovered a third photoreceptor in the retina of the eye - not used for vision. They contain a light-sensitive pigment called melanotosin and respond very sensitively to the 464 nm, which is in the blue content of light that suppresses melatonin secretion to set our internal clock. A large number of scientific studies now show that lighting closure to nature, in the form of Dynamic lighting of varying illuminance and light colour promotes health and well being of people. In other words good lighting has a new dimension which considers biological impact of light -Beyond lm/w.

INTRODUCTIONA traditional approach by practising electrical engineers, for existing or new projects, is saving the energy for all electrical equipment including lighting. When it comes to lighting design the references are made to IS 3646 for Indoor Lighting, IS 1944 for Road Lighting, National Lighting code 2011, ECBC code 2007, Green Building requirements etc. where lumen per watt (lm/W) of the light source considered is one of the factor for designing to comply the energy savings. This is now changing with Research in the fields of chronobiology, photobiology, and scotobiology that how environmental light directly impacts the human body and brain.

capturing ambient environmental light signals involved with aligning the human master biological clock was cited by the prestigious journal SCIENCE (1) as one of the most important breakthroughs of the year. Translated into a practical understanding and application, this discovery has a direct impact on the way modern day buildings are designed, constructed and lighted. To the best of our knowledge Deborah Burnett made the first attempt (2) to bridge the gap between science and applied lighting design by presenting a user-friendly perspective of the human circadian system and how this impacts the design of our built environments making reference to as many as 109 papers. On Mar 27, 2014 licht.wissen 19 titled “Impact of Light on Human Beings“, Authored by licht.de (3) making reference to 46 standards and literature which explains the topic through several articles compiled by members on research done till date of publication and practical guidance on several applications.

Third photoreceptor in the eye The biological effectiveness of light is possible thanks to a third photoreceptor in the eye discovered by scientists in 2002. Prior to that, only two types of receptor were known: cones for colour vision and more light-sensitive rods, which enable us to see even when illuminance is low. But a few years ago, researchers discovered special intrinsic photosensitive retinal ganglian cells (ipRGC) in the retina that do not have a visual function. They contain a light-sensitive pigment called melantopsin and respond very sensitively to the blue content of light.

The newly discovered photoreceptors have a direct link to the brain, the ganglion cells send signals through the retinohypothalamic track, which connects them directly with the so-called master clock – the suprachiasmatic nucleus (SCN) that coordinates the many tiny clocks in the body – the pineal gland and the

hypothalamus, which is probably the most important control centre of the autonomous nervous system. (Fig1)

Fig.1: Sensitive Ganglion Cells in eye

Human beings and biorhythmsAn internal clock controls not only our sleep and waking phases but also our heart rate, blood pressure and mood. Many of our bodily functions are cyclical. Chronobiologists distinguish between three major categories based on length of cycle:● Ultradian rhythms span only a few hours. Examples include hunger, sleep and waking phases in infants. ● Circadian rhythms are geared to day and night. They last around 24 hours. (Fig2)● Infradian rhythms have cycles longer than 24 hours. They can be a response, for example, to changing seasons. Some people are so much affected by lack of light in the dark months of the year that they succumb to seasonal depression (Seasonal Affective Disorder = SAD).

Fig.2: Circadian Rythms

Hormones as messenger substancesMelanopsin receptors containing ganglion cells are evenly spread over the retina and are most sensitive in the lower part of it. They supply the brain with information that helps determine whether we are alert or sleepy – because the light signals they pass on are an important cue for synchronising

our circadian rythms, the biological processes that occur in cycles of around 24 hours. Melatonin and cortisol, in particular, play an important role here because they impact on the body in opposite cycles.(Fig 3)

Fig.3: Visual & Biological Path from Eye to Brain

● Melatonin makes us feel drowsy and slows down bodily functions for a good night's sleep. In this phase, the body secretes growth hormones that repair cells at night. In the morning, the level of melatonin in the blood falls. ● From around 3 a.m. onwards, the adrenal cortex produces cortisol, a stress hormone that stimulates metabolism and programmes the body for day-time operation. During the course of the afternoon, the cortisol level in the blood falls and, when daylight fades, the internal clock switches to nigh ( Fig.4)

Fig. 4: Influence of Daylight on the human body

● The mood-enhancing, motivating messenger seratonin helps us reach a number of performance peaks during the day.

Blue light is the key To work smoothly, our body's hormone balance needs to be supported by external stimuli. That calls for the right light. The maximum sensitivity for the melanopic effect of light is at a wavelength of 460 nm (blue). That means that melanopsin is especially well stimulated at this wavelength. Light with a high blue content in the morning ensures that melatonin production is effectively suppressed and

cortisol can take over. We are bright-eyed and motivated. At the same time, however, light with a high blue content late in the evening can disrupt our internal clock – because while natural light weakens and turns yellow in the evening, cool white artificial light slows down melatonin production. As a result, we find it harder to fall asleep, sleep less deeply and do not feel rested the next day. Daylight - white light with a high blue content (wavelengths between 460 and 480 nm) is the most biologically effective.

Lighting Design StandardsProfessional lighting concepts today have the ability to create biologically effective lighting indoors. To ensure that the light really does have a melanopic effect and at the same time provides comfortable visual conditions, lighting designers need to pay attention to a number of factors as discussed above. They are well considered while preparing the following standards● Design recommendations are provided in the draft pre-standard DIN SPEC 67600.● Draft ISO/TC 274 N 201 Dated 2015-07-6 titled Biologically effective illumination — Design guidelines● CIE 218:2016 - Research Roadmap for Healthful Interior Lighting Applications● WELL Building Standards from USA which providing mealanopic Illuminance table as detailed below (Fig.4)

Fig. 5:Malanopic Lux as defined by WELL

WELL provides this example: If incandescent lights provide 200 lux in a space, they will also produce 108 equivalent melanopic lux (incandescent light lux x melanopic ratio = 200 x 0.54 = 108 EML). If daylight is modeled to provide the same visual brightness (200 lux), it will also provide 220 equivalent melanopic lux (200 x 1.10 = 220 EML). See the WELL reference Tables L1 and L2 for more on melanopic ratios for different light sources and how to calculate EML (WELL

v1.0, p190-192). See more at: http://www.terrapinbrightgreen.com/blog/2015/07/biophilia-parallels-well/#sthash.S4OAanjy.dpuf

Lighting for non-visual (Biological) effectsFor technical reasons and because of the need to save energy, lighting for non-visual or biological effects cannot simulate natural daylight precisely. But it can provide valuable support. In following paragraphs the parameters as needed for Malanopic effects are discussed.

Melanopic (Biological) effects are achieved by● Higher illuminance● A higher blue content planar light sources● Time-variable dynamic light and● Correct timing: biologically effective light is most effect in the morning, after hours of darkness.

IlluminanceAlthough blue spectral content is crucial for achieving a biological effect with artificial lighting, light colour is not the only factor that needs to be considered, another key variable is illuminance (measured in lux (lx)). What counts is the vertical illuminance at the observer’s eye, which is largely defined by the perceived luminance of the surfaces observed: for compliance with DIN SPEC 67600, it needs to reach at least 250 lux at 8,000 kelvin because anything less has no significant demonstrable biological effect. At other colour temperatures, illuminance needs to be adjusted according to the new DIN SPEC 5031-100. Studies show, for example, that 500 to 1,500 lux illuminance can be biologically effective at a workplace. Activation with cold white light in the evening can lead to sleeping problems/insomnia or to less restful sleep

White LEDs have a peak in the spectrum at a wavelength of approx. 450-460 nm. Since this range is very close to the maximum for the melanopic effect of light of 490 nm, they are generally very suitable for stimulating melanopsin. The same is true for warm white LEDs. An illuminance of a mere 30 lx with warm light low colour temperatures (3,000 kelvin or less) is enough to significantly reduce the

melatonin concentration in the blood.

Include larger areas in planningFor light to reach the particularly sensitive photoreceptors in the lower and nasal part of the retina, it needs – like daylight – to come from a planar light source and enter the eye from above.

Fig. 6:Areas within field of vision v/s. effective biological light

In this context it is important to give more consideration to larger areas within human’s field of vision when designing lighting. (Fig.6). Circadian efficiency can certainly not be achieved with accent lighting. The approach to be adopted for planning is found outdoors- diffuse light from the sky takes up a large area in human's field of vision.

Consider direction of lightFor activation, ambient lighting over a large area in the upper half of the room (e.g. through indirect lighting) plays a big role since this has a greater biological effect than in the lower half of the room. This light reaches the lower half of the retina in which most ipRGCs are found. This is comparable to diffuse, cold white light from the sky outdoors (correlated colour temperature approx. 10 000 to 25000 K). Evening light should be directional to minimise stimulation of the melanopsin-containing photoreceptors in the eye.

Consider dynamicsGenerally, daylight should be taken as a role model. Daylight (Fig.7) defines the parameters for biologically effective light.

The brightness and colour of daylight varies considerably, depending on geographical position, weather, season and time of day. In the majority of cases, however, the daylight admitted by windows does not reach deep into the room.

Fig.7: Daylight variation in terms of colour and brightness

Here the situation is permanently dynamic as far as illuminance and colour temperature are concerned, during the day, it should be close to that of natural light with a high blue content. An attempt should be made to consider this when planning human centric lighting. However, the changes should never be abrupt but should take place slowly and almost unnoticed, as in the natural world.Another key consideration is the right light at the right time.

The right light at the right timeLighting for non-visual effects can influence biological processes in two ways. The first -lighting concept A (Fig.8) conveys a sense of day/night rhythm even where daylight is in-sufficient: illuminance and the blue content of the light are steadily raised through up to mid-day and then gradually lowered again through to evening.

Fig. 8: Daylight simulation

The second variant - lighting concept B (Fig.9) can take the form of “light showers”. which have an energising effect and promote concentration.

Fig.9:Occasional Light Showers

During the day – in the morning and early afternoon● Time for activity and high performance● Biologically effective light should stimulate- planar light- daylight white with a high blue content- high illuminanceIn the evening and at night● Time for rest, regeneration and sleep● No activating effect required- direct lighting- warm light colours with low colour temperatures (3,000 kelvin or less)- low illuminance.

Fig. 10:Circadian ( Biological ) Lighting effects

Shift workFor people who work shifts, the requirements that need to be met by melanopically effective lighting are very complex. A shift-worker’s circadian rhythm is often different from the sleep/wake rhythm that nature in-tended. Hence the call by chronobiologists for shift work models that are less disruptive for the human biological clock. DIN SPEC 67600 contains proposals for supportive lighting.

Lighting quality and energy efficiencyGood lighting is lighting that meets human needs and nowadays also environmental standards. Lighting quality and energy efficiency are not conflicting goals. With modern lighting technology, circadian effective lighting can be realised without jeopardising energy saving targets

How energy-efficient is circadian-effective lighting? Does circadian lighting consume more energy than conventional lighting? Answering those questions calls for a detailed professional lighting design and a cost effectiveness analysis that permits fair comparison with the alternatives.

However it is also a question of perspective- if a circadian lighting installation is compared with the best available LED technology, the answer to

the question of higher consumption is YES. But if it is compared with an older installation replaced in the course of refurbishment, the answer is a clear NO.

To ensure compliance with the limits or achieve even greater efficiency, modern lighting management should be used with efficient light fittings such as LED luminaires. Lighting control requires luminaires that are dimmable. Daylight-dependent lighting control can reduce energy con-sumption by as much as 35 percent. Combined with timers and presence sensors, economies of 55 percent or more are actually possible.

To explain above points see the example of an office with old to new light source and maintaining the standard . If Circadian lighting is compared with OLD installations there is energy savings.

Because annual electricity consumption has steadily decreased in recent decades, the age of the existing installation plays an important role. The following example – a lighting installation for a 37m² four-person office – shows why. If the lights are on for 2,750 hours a year), annual consumption will be as follows:

For the assessment and calculation of electricity consumption it is important to consider that circadian effective LED lighting changes light colour and horizontal illuminance during the course of the day, while always meeting the normative requirements of the standards (here DIN EN 12464-1.) The change in illuminance in particular has a major effect on energy consumption. ( Fig 10 &11 ).

Fig. 10:Example of Circadian Lighting in office

Fig. 11:Example of Energy Consumption in old v/s. new office lighting installation

Areas of applications In other parts of the world further research has been done on how Human Centric Lighting or biologically effective lighting can be realised in practice for different applications – and what positive results have been achieved in field studies. The most successful studies have been done, by organisations like Philips, GE, Osram, National Institutes of Health (NIH) U.S.A., Lighting Research Centre (LRC) U.S.A., and many more researchers from all over the world, in areas like Offices, Industries, Hospitals with Shift workers, Residences, Retirement homes and Schools where positive results are achieved by using biologically effective, dynamic lighting (or Human Centric Lighting or Tunable white Light as named in market)

Some Quotes● According to George Brainard, a neurologist at Thomas Jefferson University in Philadelphia and one of the first researchers to study light’s effects on the body’s hormones and circadian rhythms. “Light works as if it’s a drug, except it’s not a drug at all”. ● Light is critical for our health and wellbeing. Ensuring that we receive adequate light levels at the appropriate time of day benefits our alertness, mood, productivity, sleep patterns and many aspects of our physiology,' says Dr Victoria Revell, a chronobiologist at the University of Surrey.

● ‘Light is a drug, so let’s administer it correctly’That is the view of Professor Herbert Plischke, of Munich University of

Applied Sciences. According to him the right light – at the right time – can stabilise hormonal rhythms, enhance night-time melatonin secretion, improve sleep quality, increase day-time vigilance and raise our resilience to stress. Further he wants lighting companies to take more responsibility for how their products affect the human body

ConclusionThe full dynamism of daylight cannot be delivered by artificial lighting. However, a large number of scientific studies now show that lighting is geared to nature, in the form of Dynamic lighting of varying illuminance and light colour : ● Enhances the human biorhythm● Promotes relaxation & good health ● Heightens our sense of wellbeing ● Boosts motivation● Improves mood , performance and concentration● Prevents sleep disorders ● Speeds up convalescence● Provides stimulating light for more vitality and a better quality of life.

Dynamic lighting recreates the biological effect of natural light indoors with the turn of a dial or the touch of a keypad, in accordance with whatever effect is desired, bringing daylight into the building and supplementing it, as required, with artificial light of the right brightness and colour temperature. Given that we now have a type of light source - LEDs - that can be spectrally tailored to suit our needs, wants, and whims (visual and otherwise) and given that our knowledge of the non visual

functions is growing by leaps and bounds, it stands to reason to develop new metrics as science advances. In the near future, research findings will further highlight the importance of biologically effective light. Energy efficiency will then also be redefined- it will be measured according to the balance achieved between use of resources, ergonomic performance and biological effect.

Chronobiologists, lighting manufacturers, architects and lighting designers now have a chance to pool their resources and efforts for substantially improve our health & wellbeing and quality of life.

We as a Lighting Designer strongly recommend that Beauro of Indian Standards should also include in the standards the Lighting Parameters as needed for Biological effective Light for health and well being of people and in turn quality of life in India. Further as an Educator, we also strongly recommend that

specifiers and users should be well educated through series of seminars by manufacturers,References1) Duffy JF, Wright KP (2005 ) Entrainment Of The Human Circadian System By Light.

Report on the International Conference and Exhibition on“Smart- Lighting-The Future” held at Bengaluru duringNovember 4-6, 2016

Background : Illumination technology has taken a new dimension in recent years with the technological advances and popularization of LED based lamps and fixtures. The Government of India is also promoting this technology by encouraging LED usage in homes, offices, streets and public buildings. Some reports have emerged about the possible health related issues due to blue component in artificial lighting. Then there are complex compliance and regulations which cannot be understood by average persons. In view of these, Indian Society of Lighting Engineers, Karnataka State Centre (ISLE-KSC) organized this International Conference and Exhibition to disseminate information and knowledge about this fast developing and exciting field.

Inauguration : After the traditional invocation, Shri M.S.N. Swamy, Chairman,

Dr.Subhash Chandra Khuntia, I.A.S., Chief Secretary, Government of Karnataka inaugurating the conference on ‘Smart Lighting-The Future’ by lighting the oil lamp. Shri.M.S.N.Swamy, Chairman, ISLE-KSC, Shri S.Sumanth, Director (Transmission), KPTCL and Shri H. Mukherjee, Vice President, ISLE looks on

Panel Discussion : The technical sessions were followed by a panel discussion on issues not covered in the presentations and for open, free, informal and frank exchange of ideas and thoughts. The panel was chaired by eminent architect Prof. Jaisim. Shri Bhavani Prasad (formerly Director General, CPWD, New Delhi), Shri Srinath Aanegola (Eaton Ltd.), Shri Pravin Borse (Hi Physix) and Dr. B. K. Chandrasekhar (ISLE-KSC) were the other panelists. The panel members had varied technical backgrounds with rich experience. It was heartening to see the tremendous interest and participation by the delegates in airing their views and discussing issues with different perspectives.

Prof. Jaisim with his wide experience and knowledge ignited enthusiasm with thought provoking statements. Few of the issues discussed and highlighted were:

● Many of our current luminaires are ‘ugly’ and not meant for LEDs.

● Overcome the trend to retrofit only.

● New designs for luminaires are needed.

● Mismatch between architects and lighting engineers during planning stage.

● Retrofit is the need in India currently for a large section of the population.

● Moving forward, psychology of lighting will be the trend taking in to consideration cultural issues.

● Productivity and well-being in workplace are contradictory in some cases.

● Need for integrated approach between

stakeholders for lighting installations.

● Non-availability of lighting designers in the country as they are few in numbers.

● Need to address challenges faced by lighting industry from learnings of other sectors.

Program on Skill Development : The half day session titled ‘Technical Session on Skills Development’ was jointly organized by ISLE-KSC and ESSCI (Electronics Sector Skills Council of India), Govt. of India and completely dedicated to Skill Development. Shri Saleem (ESSCI) highlighted the mission and role of ESSCI and suggested inputs from the industry about issues of quality and quantity. Based on these inputs, modifications of the courses can be formulated. Some the issues and challenges faced by the lighting industry on different aspects were highlighted by Shri Srinath Aanegola, Eaton Ltd. (representing large scale manufacturer), Shri C Chandrashekar, Intelux, (representing MSME) and Shri Mathew Kurian, Light and Lighting (representing distributors). Shri Ravi Rao gave the perspectives from the view point of colleges/universities with which he had

interacted and had some data. Shri Srinivas of ESSCI gave his comments with explanations on some of the issues raised. He indicated that the current training modules focus both on technical (how to work) and soft skills (how to behave in workplace). With specific inputs from the industry, the modules can be revised and refined. Regarding establishment of Test Centres, he indicated the support from ESSCI, if their sustainability is addressed by the industry in the long run.

It was refreshing to see such a massive movement quietly undertaken by ESSCI with different levels of training without ignoring less educated persons who are skilled perhaps in electrical installations, carpentry, painting, welding and the like where opportunities for skill development were lacking earlier. It was an eye opener for most of the delegates. The program ended with a small panel discussion.

Release of ISLE Newsletter : Light India International (LII), the official magazine of ISLE (Nov-Dec 2016 issue) was released by our senior member Shri Bhavani Prasad and Chairman Shri M. S. N. Swamy in

presence of Shri Dilip Kumbhat, President, ISLE. Copies were distributed to the other dignitaries on the stage.

Life Time Achievement Awards : During the conference, three eminent persons namely Shri M.S.N. Swamy, Chairman, ISLE-KSC, Shri Anthony Augustine, Innovator from Bengaluru and Shri Dilip Kumbhat, President, ISLE were honored with ‘Life Time Achievement’ awards. A statement of achievements was read for each of them by Shri Pradeep Nettur and the three were felicitated with traditional ‘Mysore Peta’, shawl and garland as is the practice in the region. The audience applauded each of the awardees and it was indeed a pleasant event with broad smiles all around.

Overall, the conference met its objective of dissemination of information and knowledge smoothly and successfully with the cooperation of ISLE office bearers, members, delegates, invitees, exhibitors, speakers and authors of articles.

TOKYU HARVEST CLUB, KYOTO, JAPANThe Tokyu Harvest Club is located in a mountainous area of historical Kyoto city. The architecture and interior design feature traditional Japanese details, but also infuse modern Japan and current trends. The lighting designed by Iris Associates is similarly refined, blending grace and tranquility with the interiors.

The wood ceiling illuminated by buried LED lights welcomes visitors to the entrance lobby. The central art object of the space is lit by fiber optic illumination like scattered stars, and floodlighting of the custom-made super narrow spotlight focuses only on the object.

“This lighting is playful, quiet, dramatic and concealed all at once,” one judge wrote. In the lobby, designers worked to evoke the scenery outside. Illuminating slits along the pillar connects the spaces outside and inside, while the motif of the moon is used for focal points of light.

The illumination integrated into the 110-meter long Japanese transom plays an important part in the lounge. LED strips are placed between the lattice of double layers, lighting up the back side and silhouetting the front to add a layer of light and shadow. In spite of its length, the total power consumption for the transom is 1.3kW. The lounge’s lighting control system plays several preset scenes throughout the day, adapting to the natural light and corresponding with various purposes.

“With this project, the designers were able to demonstrate their sensitivity when dealing with light as an architectural medium,” another judge shared.

The confetti-like artwork in the restaurant is illuminated by controlled lighting under the theme of the four seasons, changing throughout the year. Outside, wooden walls and bamboo surfaces are lit up, reflecting in the water surface. The egg-like structure floating in the pond is illuminated by optical fibers from under the water, and from above by floodlights that wax and wane. Variable color temperature LEDs give visual comfort and create a meditative quality to the space.

The expressed there interest for future collaborative research work.The glimpses of the invited talk session has been shown in Fig.6 & 7.

3. Research Associate meet / Sharing of the research work: The research focus ofthe department can be divided into the areas of outdoor lighting, indoor lighting and measurement technology, is being researched in all areas relating to Visual Perception, Non Visual perception and efficiency. It takes place both basic research and applied research. An important area in all research matters takes the LED technology. The wide range of research topics requires a high level of professional and technical competence. During this Lighting Chair, TU Berlin visit, it was also a very important component of the visit. Here mainly the research sharing with the three research associates has been elaborated.a) Measurement of Threshold Increment from the driver’s point in road lighting applicationName of the research associate Dipl.-Ing. Serkan Önel This research project shows how the glare parameter Threshold Increment can be measured experimentally.The principal purpose of road lighting is to produce quick accurate and comfortable seeing at night in order to provide safeguard for vehicle’s and pedestrians. To achieve this goal standards and recommendation have been given proposed by the several international bodies that specify acceptance criteria for various road classification based on road surface luminance, Veiling

luminance, horizontal illuminance and certain visibility parameter. Modern road lighting designs are done by using computer software to ensure that the above acceptance criterions are being fulfilled. Current theoretical software designs based on current practice and recommendation but discrepancies between theoretical designs and actual lighting installation are sometimes apparent specially for country like India where most of the cases the roads are mixed in nature with more motorized traffic density and the surfaces are not yet standardized and also the roads are yet to be classified properly.Now at the time of driving a motorist’s visual performance can be accessed with respect to the detection of the objects in the on axis (2- degree field of view) as well as in the peripherals or off axis. As we know glare is one of the important parameter for road light designs. A driver faces lots of discomfort due to disability glare. This research work addresses the Discomfort glare assessment for motorists. The experimental setup includes a driver simulator which may simulate a car driver in a road and a glare source i.e. a beamer. This project output will be a valuable methodology for evaluation of Threshold Increment in road lighting installations.

b) Development of adaptive lighting with multi variable light distribution for demand lighting of road space: Name of

the research associate: Dipl.-Ing. Juri Steblau The project of the Technical University of Berlin, focusing on the determination of target parameters for the intelligent control of lighting systems, which can react adaptively to needs and environmental changes. An optimal illumination of the traffic space depends on many different factors. In addition to the geometry of a road and temporal factors such as traffic density, the weather conditions and the ambient brightness, but also the development plays a crucial role. To ensure optimum traffic safety at the same time energy efficiency, as many of the above factors must be considered in lighting design. The aim of this research is the development of luminaires, which guarantee by the superposition of individual light distribution curves adaptive light distribution to changing environmental influences. Existing lighting solutions realized only a light distribution and are therefore suboptimal regarding traffic safety and energy efficiency. The LED luminaires made with the different lenses are controlled with an efficient way to achieve glare free most optimized lighting solution.

c) Non-visual light effects : Human Factors in LightingName of the research associate: Inga Rothert Light is not only the acquisition of visual information, but also synchronizes the circadian rhythm of humans and has on many body functions influence. Since the discovery of a third receptor in the retina, the ipRGC cells, and research is being conducted in this field intensified. That the non-visual effects it depend on a variety of parameters such as spectral and spatial radiation distribution, age etc. Today the lighting system is becoming moreover Human Centric in nature. This research work is going to address the human performance under different spectrum too. These investigations are carried out, which are comparable and generalizable by standardized test conditions. In addition to the spectral and spatial distribution of radiation parameters such as age and chronotype the subjects to be considered. As a result, it will be shown how much potential a spectrally matched to non-visual effects lighting. Recommendations for the development and application of lighting solutions to ensure that the general lighting in the future not only meets visual tasks, but does not support visual effects.

4.Interaction with Prof. Stephan Völker :During the interaction with Professor Völker, he explained about their curriculumfor Electrical Technology, undergraduate course & Lighting Technology for the post graduate courses. He also explained the scopes of collaborations they have with their industry & public works department. He expressed a deep interest to initiate some research collaboration with us in near future. He assigned some road lighting related research problems for my students at Jadavpur University.

5. Visit to a renowned photometric and colorimetric instruments manufacturing company LMTIt was a great experience to visit this world famous photometric & colorimetric instruments manufacturing company LMT. During the visit all possible types of traditional and modern photometric and colorimetric instruments have been seen from its manufacturing stages. It was really an outstanding experience which will help me in teaching about the modern trends in photometry in future.

Understanding light is about understanding the qualitative aspect of lighting design. While light is being defined and described as a radiant energy or wave form etc, it can also be understood as a medium which connects human beings with the environ-ment, creates a sense of vision and thereby enables us to understand the Space, forms, activities, etc around us.This medium has a character, which defines and renders our perception of the environment around us. Therefore the quality of this medium is of paramount importance for the lighting design science. We judge our environment upon how well lit it is, and our activity performance in the environment depends on the visual information received from this environment. The quality of the light in the environment governs the quality of the desired visual information and thereby our performance. The well illuminated space, reveals this information efficiently to the user thereby enabling one to perform satisfactorly. Quality lighting can be further understood by five aspects visual needs, environmental attribute, biological factors, human preference, and efficiency.

Understanding Light

Mr. Vinay BabarChairman, M.P. State Center (ISLE)

Illustration change in perception with varying lighting condition

Visual needs: Every space is designed to house a certain activity or function. For a good lighting condition, we need to understand and analyse the activities, and visual needs of human beings for performing these activities. Task can be categorized as vertical or horizontal, chromatic or mono-chromatic, criticality of the task, etc. Every such task character has different lighting solution depending on its visual needs. Therefore merely following lux level standards for threshold visibility may not necessarily derive to a qualitatively correct solution.

Environmental attributes : Any environment designed for any function should enable human beings, to do that activity and function efficiently and should make one happy while doing that. A light should, therefore enable the human beings to relate with the environment, easily and

Illustrations for different visual needs for different activities.

should make it a pleasure experience while doing so. One may not be able to increase visibility of the subject or object in the environment by merely increasing the incident illumination. Other factors such as CRI (Colour rendering Index), relative contrast, visual acuity, which have an interface with our immediate environment are vital for enhanced visibility.

Biological factors: Our brain continuously monitors the environment with its all aspects, for relevant information, based on which it guides other parts of the body for their respective and relative action. These biological phenomenon occur only after the correct perception of the environment with its attributes. Therefore it is important to

Illustration for varying environmental aspects.

have this relevant information being reveled and being perceived by us. Good lighting compliments these biological aspects of visual information and enables human being perform efficiently.

Human prefernce: Human beings have certain preferences of ambient light of our visual field in the environment. Often these preferences are personal and could be out of geographical and cultural conditioning. This is observed as preference for particular colour temperature in specific geographical condition. This occurs as eye, and brain are

tuned to adopt a specific environment with peculiar and prevailing lighting condition at specific colour temperature, any change in the colour temperature, thereby changing perception of the environment may not satisfy these preferential requirement. Such preferences can be observed with the aging people where sensitivity of glare increases or change in the orientation of the task lighting on a work desk etc.

Illustration for change in the task identification in differentlighting selection.

Efficiency: Efficiency is a vital aspect of a qualitative lighting application, as most thought fully crafted elegant lighting solution may fail to prevail, if it is not efficient for energy consumption. With reducing natural resources and burgeoning requirements, we are posed in a situation, where lighting science needs to develop solutions which are energy efficient and environmentally sustainable. But very often in developing, energy efficient products the quality aspects of the qualitative lighting are compromised. Often energy efficiency and sustainability is thought for in the product inception stage, but same or even more effective solution can be arrived, with addressing lighting requirements as per the ergonomic merits. As the correct lighting design exercise would ensure optimum lighting for each aspect of the space considering all design objectives such as: visual needs, environmental attributes, biological factors, and human preferences, it would also make lighting solution more efficient.With all aspects discussed above, and new trends in lighting technology, advanced and efficient lighting product, we can certainly arrive for lighting solutions which ergonomically correct, visually appealing, interesting and efficient. Thereby make it a qualitative lighting, as we want to understand it (light).Presented Illustrations :Credits Semblance design studio1) Sandvik coromont salaes office, Pune2) Hotel Kanan, Ahmedabad3) Camshot Academy, Pune4) Pratha jwellery studio, Pune

KIRIKKALE MERKEZ NUR MOSQUE, KIRKKALE, TURKEYThe design approach for this ornate mosque was to emphasize the spiritual identity of the space and to create an icon for the city of Kirikkale. The designers from Zeve wanted to enhance and define the structure via their lighting applications, highlighting architectural elements, adding depth, and differentiating the surfaces and materials wherever possible.

Inspired by late Ottoman architecture, the mosque consists of a main dome, four secondary domes, five entrance domes, and four three-balcony minarets. Color temperatures were selected in order to create fine gradations between these complex surfaces from the bottom up. The main dome was lit in 4000K, while the entrance domes and carrier columns were given 3000K, and spots and washes of2700K add a mystic appearance and lend contrast at various points throughout the structure, creating shadows and sparkles on the crescents.

“The application of ‘just enough’ light to the exterior and good use of warm and cool sources complements the character of the façade elements,” praised one judge.

Light and shadow give form and definition to the building. While the half-domes were left in the dark, the patterned windows underneath were lit. Big windows were defined by applying narrow beams of light, creating sharp dark surfaces between them. To ensure harmoniousness between illuminated surfaces, various optics and different wattages were used. Even the lighting levels under each balcony were aimed to be the same.

“Beautiful, sensitive modeling of the mosque’s three-dimensionality allowed for a lighting solution that enhances the architectural form and shows a considered and successful approach to color temperature,” wrote another judge.

To save the daylight appearance of the architecture, products were painted in the color of surfaces and placed in the niches and behind flowerpots wherever possible.

Energy consumption was minimized by LED luminaires and optional lighting scenarios to be applied at different times. The light changes over the course of the evening - saving energy and preserving the nighttime sky. A beautiful, sensitive balance.
