Comfortable working environment with LED lighting

The responsible wayforward in office lighting As a responsible corporate citizen, Philips has a long-standingcommitment to providing lighting solutions that improve people’slives and are environmentally sound.

And as the industry leader in lighting, we are constantly striving todeliver innovations that meet the present and future needs of thepeople who use and experience our products.

New wave in office lightingWith the trend toward a knowledge-based economy, human factorslike staff well-being, motivation and retention are crucial forbusinesses today.

Flexible and inspirational, lighting can play a key role in the officeenvironment, helping to make people’s working lives more enjoyableand productive.

In offices, we are seeing a clear shift from functional lighting towardsintelligent, dynamic lighting. We continue to drive this trend withinnovations based on sustainable, energy-efficient technologies suchas LEDs.

LED – the way aheadSolid-state or LED lighting represents the most significant developmentin lighting since the invention of electric light well over a century ago. Itoffers unprecedented design freedom in terms of colour, dynamics,miniaturization and architectural integration, as well as significantadvances in energy efficiency and lifetime. In particular, the rapiddevelopment of high-power white-light LEDs is set to revolutionize theway we light our homes, cities, shops and offices.In our new range of LED office products, we managed to master typicalLED-related challenges originating from the high brightness and thecolour rendering of this new light source. All our office products arecompliant with the European standards with respect to direct andindirect glare, as well as colour rendering.

In exploring the needs and desires of our customers and end-users inoffices, we have identified three key lighting themes – well-being,ambience and the environment.

LED lighting and well-being – enablinghigh performanceLighting doesn’t just help us to see better, it also affects how we feel.Daylight – the form of light with which we are most comfortable –changes in level and colour temperature throughout the day, affectingour emotions, moods, perception and performance.

In high-intensity working environments like offices, the dynamics ofdaylight have been shown to have a stimulating and inspiring effect,enhancing staff motivation and well-being. Utilizing this potential,Philips has developed Dynamic Lighting, and it is incorporated in ourLED office lighting range. These LED-based solutions can becontrolled in colour temperature and dimmed. This means that officeworkers can also adapt the environment to their personalpreferences, enabling them to perform even more effectively.

Using LEDs for office lighting brings the challenge of transforming thehigh brightness of the LED point source into a glare-free surface oflight. Philips applies advanced technologies to ensure visual comfortthat meets office lighting norms.

DayWave Philips has developed DayWave – the first LED-based luminaire forfunctional office lighting. Incorporating cool and warm-white LEDsand an innovative optical system, this organically shaped fixture hasbeen specifically conceived to create a more natural, inspiringambience, in order to enhance staff well-being and performance.DayWave uses the innovative Micro Lens Optic (MLO) with anadvanced optical system to ensure full compliance with the Europeanstandards on office lighting (UGR 19, 1000 cd/m² at 65º).

Ambience creation through LED lighting –ever-changing atmospheres

Lighting provides a unique way to transform oursurroundings and create appealing, emotionally upliftingatmospheres. Thanks to their dynamic, colour-changingcapability, wall-washing effects and ease of control, LED-based solutions enable an ever-changing palette of lightingambiences.

Colour is more powerful in evoking an emotional responsethan white light. In offices, (changing) coloured LED lightingcan be used to create a more vibrant and dynamic workingenvironment. It can also be used to adapt the ambience ofa room for a specific purpose, for instance turning a simplemeeting room into an inspiring environment for a creativebrainstorm session, or making the company restaurantsuitable for a business dinner with a client.

Focusing attentionIn public areas of offices, colour and colour-changing areexcellent means of directing attention. Here too, LEDs arehighly effective, as their saturated colours exert a strongvisual attraction.

When repetition of a colour or a colour combination in acertain context is associated with a company, ‘branding’ hasbeen successful. LED-based coloured light can also be usedto increase or reflect corporate identity in office buildings.

LED solutions for offices

At Philips, we strive to improve people’s quality of life, aswell as the quality of the world we live in. We do this in avariety of ways – for instance by reducing the environmentalimpact of our products and processes.

Going beyond legislation, we believe we can help create asustainable future by developing innovative lightingsolutions that are kinder to the environment (minimizedhazardous substances) and offer lower cost of ownership(maximized energy savings and lifetime).

LED office lighting – the future’s here todayPhilips covers the entire solid-state lighting value chain and is at the forefront of the development of this new technology.We now offer complete office norm-compliant LED lighting solutions that improve people’s lives and are environmentallysound. In 2008 we achieved a milestone in this regard, lighting the office of French insurer Generali on the Champs-Elysées in Paris – the world’s first office to be lit entirely with LED solutions.

LED solutions like our new LED-based downlight offersignificant environmental benefits. They are free ofhazardous substances, highly efficient (low W/m2), long-lasting, reduce waste (miniaturization) and prevent lightnuisance (no spill light).

In flexitime working environments like offices in particular,the energy and cost-saving potential of LED-based lightingsolutions, in conjunction with our advanced lightingcontrols, is substantial.

Rogier van der Heide talking about the roleof LED lighting in the office of tomorrow

What are the qualities you look for in office lighting? What doyou want to achieve when you’re designing office lighting?

What I look for is the creation of a visual environment withsufficient dynamics – visual dynamics. This doesn’t mean thelights should go up and down: within the field of view I liketo create a contrast which is pleasant to the eye, withoutstrain, without fatigue. Although compliance with the normis often a requirement, I’m more interested in a certain levelof visual dynamics, because it offers a more attractiveenvironment and ultimately therefore a more pleasantworkplace.

I can create visual dynamics by making light more targeted,more focused. But I can also work on the different materialsin the office space. They can reflect differently. So even if Ihave to make a uniform lighting scheme, I can still createvisual dynamics by changing the materials in the space. I amlooking for tight integration of these elements – light andmaterials.

How do you see LEDs helping you to realize these qualities?

They can definitely help. The total system efficacy might getclose to fluorescent fittings, but I don’t think LEDoutperforms tube light in office lighting yet. Until thatchanges, the benefits are more in the fact that they are smalland can therefore be built into all kinds of interior elements,for example a plinth, niche, cove, etc. That was neverpossible before in office lighting.

Clients want office lighting to be modular and flexible,because they change the layout of those spaces.Traditionally, office lighting was always in the ceiling, in a 60x 60 cm grid. Now with LED, it has been miniaturized, wehave more opportunities to put it in places where lightcouldn’t be put before – integrated in the components thatmake up the office space. For me, that is the main benefit.

LED solutions for offices

Do you see the future of office lighting being a mix of conventionaland solid-state?

At the moment yes. Ultimately it may all be replaced, but atthe moment it’s a mix, definitely. Visual attraction issomething that can be achieved easily with LED, maybe notso easily with fluorescent. Although, in our own office wehave a fluorescent system, a Philips product, with uplighting,and in that way we create visual dynamics, because we havehighlights on the ceiling.

Ambience, well-being and the environment: the threefundamentals of contemporary thinking on office lightingdesign?

Yes, what I call visual dynamics is maybe more of atheoretical term, but ultimately it creates ambience andwell-being. There are a lot of developers interested in howthese three elements link in to productivity in theworkplace. And I think developers are even moreinterested in that than business owners or employers. Theysee added value in cranking up the quality of the officespaces that they try to rent out. They are in a verycompetitive market. They have to offer values other thanjust square metres and air conditioning. So they are alllooking for differentiation, and offices that specifically focuson sustainability and well-being in the workplace will have acompetitive advantage.
