II. BIRTH HISTORY OF HIND LAMPS LTD
In the town of Etawah, Shikohabad, where presently Hind Lamps is situated, was infact a cotton
factory which was closed that time.In 1934-35, a contractor purchased this land and building
and started work of manufacturing lamps. It was named Hindustan Lamps Works Ltd. At that
time area was 35 acre and production capacity was 1000-1200 bulbs per day. But because of
some unfavorable conditions it could not operated even for one year and was closed that time.
In 1942, A Punjabi industrialist Shri Kishanchandra Sindhi and Mr. M.L. Gava bought it
and divided it into two parts one KAYCEE INDUSTRIES LTD. which was responsible for
manufacturing electric bulbs and other was KAYCEE GLASS WORKS which was responsible
for shell of the bulbs.
But in 1947, India faced partition and due to it, RADIO LAMPS WORKS LTD. was rooted out
from Karanchi and was transferred to Shikohabad. KAYCEE GLASS WORKSand KAYCEE
INDUSTRIES was merged in RADIO WORKS LTD. But due to country conditions, economic
situation firm was not good and it became very hard to run the factory.
After some time Kamal Nayan Bajaj came and took over the firm and with the collaboration of
three Europeans and Philips setup HIND LAMPS LTD. in 1951
III. INTRODUCTION OF HIND LAMPS
Hind Lamps Ltd. is a unit of Bajaj Electricals Ltd. The factory was established in 1951.It was time of starting the Lighting industry in India. A Philanthropist, a business tycoon and
freedom fighter Shri Jamnalal Bajajs eldest son Shri KamalNayan Bajaj, himself an
eminent industrialist was at the helm of the Bajaj Group of companies. It was his
entrepreneurship that bought KAYCEE GLASS WORKS. A small flame and glass shell making
factory at Shikohabad and Bajaj Electricals together combined to establish a factory. During
1946-47 KAYCEE Glass Works amalgated with Bajaj Electricals.
In the year, 1941 the Bajaj Group took a step forward. It entered into collaboration with N.V
Phillips Glaileampen Fabrieken of Holland and three leading British Electricals firms association
Electricals Industries Ltd. Crompton, Parkinson Ltd. and G.E. Electricals formed Hind Lamps.Bajaj Electrical provided half of the capital while European brought in the other half of the end.
Phillips provided technical management. This was a time when joint venture was rare unlike
today. The agreement was signed on 23 Nov. 1951. Hind Lamps commenced operation on 1st
January 1952.

VI. FLUORESCENT TUBULAR LAMP(FTL)
BASIC PRINCIPLE OF OPERATION:-
A fluorescent lamp is a glass tube containing some mercury vapour, with a phosphorescent
coating on the interior surface of the tube. The mercury vapour is made to glow by using a high
voltage across its electrodes that sets off an electric arc discharge in the tube. The discharge canalso be described as a conducting plasma. The resulting flow of current through the mercury
vapour is stable and well-controlled by an external ballast, or loading device, which consists of a
high-inductance choke-coil that is connected in series with the tube. The continuing dischargeglow is invisible to the human eye but it causes the phosphorescent coating on the interior
surface of the tube to emit visible light.
A fluorescent tube lamp works by using the fluorescence principle. It contains two filaments, one
at each end of the tube, which glow to heat up the gas contained inside the tube. The inner
surface of the tube is coated with compound of elements having fluorescent properties, such as
phosphorus. When it was manufactured all normal air was removed from the tube. In place of the
air just a small trace of a gas is put into the tube, such as mercury vapour (for a white color),carbon di oxide (forgreen), neon(forredcolor), etc. When the electrical supply is turned on, what
happens is that the two filaments glow and then the contacts of the starter open. This action
provides a voltage across the tube that is high enough to ionise the warmed-up gas inside thetube. This ionised gas, also called a "plasma", excites the special fluorescent coating on the
inside of the tube so that it gives out visible light.

Note about the need for a choke and a starter
Without a high inductance choke in series with the tube, the plasma in the tube would simply
short-out the service wires. That would always cause the circuit's protective fuse to blow - or itscircuit breaker to trip - to cut off the supply of current to the tube. If that happened the tube light
would never be able to perform its intended purpose, which is to continue running - and giving
out a continuous light- for long periods of time. The starter is a special kind of switch: its
contacts are made of a metal alloy which, soon after a voltage is applied, heats up and bends,
causing the switch contact stopped. So a high-inductance choke must be used in circuit with the
starter and the tube for two reasons:
firstly the choke generates a high voltage pulse across the tube when the starter's contactsopen. That pulse causes the gas in the tube to ionise and become a low-resistance plasma
and secondly, because it is wired in series with the tube, the choke greatly reduces the current
drawn by the tube once it contains the low-resistance plasma.
NOTE:- A Tube Light Is a High Vacuum and Low Pressure Device, so it is also termed as a
Vacuum Light

Let us discuss all the processes in brief one by one-
1. SUSPENSIONIt is a process in which the coating solution is prepared with the help of various
chemicals used in the suspension room.
Suspension Solution is made up of
Liquid Ammonia Allon-C (Aluminium Oxide Powder) DM Water Fluorescent Powder Water Based Binder Adinol
In this room the suspension/Fluoresent powder is prepared and it takes approx.. 8 hours to
prepare and make it for use.
7/31/2019 Industrial Training Report on Tubelights

2. COATING (300X4=1200 Shells)After the suspension/Fluorescent powder is prepared then it is filled in to the glass shell with the
help of the doser and this process is completed in approx. of 16 hours .
The coating is made on to the glass shell to convert the UV rays produced into the shell to the
Visible Light that we uses.
3. SINTERINGSintering process is lead to the drying of the chemicals used during the coating process.
As we knows , we uses Ammonia, Allon-C , DM Water, Binder and the fluorescent powder as a
suspension solution for the coating.
Here we will provide the coated glass shell to the furnace at which approx.. 600 oC of temperature
is maintained, Here we will dry all the chemicals like as Ammonia, Allon- C, DM Water, Binder
etc. At final output we get only fluorescent powder binded on to the glass shell.
4. WIPINGWiping is the brushing of the sides of the glass shell after the coating process.
It is done due to the proper capping at the ends and there is no chemicals produced at the ends
when they are mounted with the Aluminium Caps and the mounts .It is done because as the
fluorescent powder is proced at the ends they will produce defects at the packing ends of the
glass shell.
In this process the sintered glass shell is brushed at both of the ends with a fixed brush and after
that at the conveyer chain it is flushed off with the help of air pressure.
5. BRANDINGIn this process the stamp of the company or the manufacturer is imposed on the glass shell after
the coating and the wiping process.
6. SEALING (32 Heads)Sealing process is also be said to be shell and mounting and this process is done at following two
machines:-
A.Flare MachineB. Feet Machine

positions of the machine head as 1,2,3.
This machine has two burners named melting burner and Cutting Burners.
Gases- Oxygen+LPG+Blower.
SO2 is used for the lubrication at the reamer plate or flare tool.
Length Adjuster-Cutting Burner-Glazing Burner(For Smoothing)
Then the manufactured flare is sent to the next production line to feet machine for further
production.
B.Feet Machine (28 Heads)In this Proceess the mount is prepared for the tube light and this is prepared with the help of feet
machine. In this machine the lead in wire is feeded into the flared tube.
First of all the flare is put into the hopper, and this flare is moved to another position and at that
position the catcher puts up the Lead in wire and puts two wires into the flare and then a exhaust
tube is put into the flare and the process continues at different different burners and then the
mount is prepared .
And then it is annealed at different temperatures/gas pressures . It is done to make the mount
crack free.
And at the mount machine we will use an emitter to increase the resistivity of the filament.
Emitter: 5.3-7 mg
Filament: Tungsten(25-26 mm)
At MOUNT machine there are total 18 Heads.
7. PUMPINGIn this process the gases and the mercury is filled up into the tubelight and is to be packed at the
both of the ends.

XI. GENERAL LIGHTING SERVICES(GLS)
BASIC PRINCIPLE OF OPERATION:-
The incandescent light bulb, incandescent lamp or incandescent light globe produces light by
heating a filament wire to a high temperature until it glows. The hot filament is protected fromoxidation in the air with a glass enclosure that is filled with inert gas or evacuated.
Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings,
from 1.5 volts to about 300 volts. They require no external regulating equipment, have
low manufacturing costs, and work equally well on either alternating current or direct current. As
a result, the incandescent lamp is widely used in household and commercial lighting, for portable
lighting such as table lamps, carheadlamps, and flashlights, and for decorative and advertising
lighting.
Incandescent bulbs are less efficient than several other modern types of light bulbs, with most
varieties converting less than 10% of the energy they use into visible light (with the remaining
energy being converted into heat). Some applications of the incandescent bulb deliberately usethe heat generated by the filament. Such applications include incubators, brooding boxes for
poultry, heat lights for reptiletanks, infrared heating for industrial heating and drying processes,
and the Easy-Bake Oven toy. But waste heat can also significantly increase the energy required
by a building's air conditioning system.
Incandescent light bulbs are gradually being replaced in many applications by other types
ofelectric lights, such as Fluorescent Lamps, Compact Fluorescent Lamps (CFL), Cold Cathode
Fluorescent Lamps (CCFL), high-intensity discharge lamps, and Light-Emitting Diodes (LEDs).
These newer technologies improve the ratio of visible light to heat generation.

As all of us are familiar with the Tube light and the Bulbs that all of us are using at our
homes, in now a days every person is using a bulb or a tube light for its use. So the Fluorescent
Tubular Lamps and the General Lighting Services are the broad used terms in the field of the
Electrical Engineering. The production of such type of the products is a challenging term for any
of the industry to organize all the things in a proper manner.
Hence the production of the tubular lamps and the Incandescent bulbs will lead to the
development in the field of Electrical. The various advancements in this technology will lead to
the development of the various CFLs (Compressed Fluorescent Lamps) using the same principle
of the Tube Light and are producing a huge amount of intensity of light for our use in Nights or
Day in various different ways and different modes like as cool day, brighter etc.
