ON OSRAM INDIA PVT. LTD.

COMPANY

The brand name of OSRAM was "born" in 1906 and registered by the

Deutsche Gasglhlicht-Anstalt In 1919, the world famous picture logo with the light bulb also made its first appearance 1985 OSRAM integrates as the first manufacturer the electronic ballasts (ECG). On July 1, 1919 AEG, Siemens & Halske AG and Deutsche Gasglhlicht AG (Auer Gesellschaft) merged their light bulb production activities

COMPANY PROFILEThis global player has its headquarters in Munich and

employs more than 41.000 people throughout the world. In the 2007 fiscal year (to the end of September) sales amounted to 4.7 billion euros. Osram is one of the two largest lighting manufacturers in the world and has 48 factories in 17 countries Osram India is growing at very fast growth rate for last few years.

Energy saving lamps

Energy saving lampsOSRAM energy saving lamps live up to 15 times longer

and consume up to 80% less energy than conventional light bulbs. when it comes to purchase prices, OSRAM energy saving lamps quickly pay for themselves and save you money for a long time to come

Halogen lamps

Halogen lampsy Halogen lamp is an incandescent lamp with a

tungsten filament contained within an inert gas and a small amount of a halogen such as iodine or bromine. The combination of the halogen gas and the tungsten filament produces a chemical reaction known as a halogen cycle that increases the lifetime of the bulb and prevents its darkening by redepositing tungsten from the inside of the bulb back onto the filament. The halogen lamp can operate its filament at a higher temperature than a standard gas filled lamp of similar power without loss of operating life

LED lamps

y lamps can be made interchangeable with other types of lamps. A light-

emitting-diode lamp is a solid-state lamp that uses light-emitting diodes (LEDs) as the source of light. The term "LED lightbulb" is also colloquially used. "LED lamp" may in general refer to conventional semiconductor light-emitting diodes, to organic LEDs (OLED), or polymer light-emitting diodes (PLED) devices, although OLED and PLED technologies are not commercially available in 2010. y Since the light output of individual light-emitting diodes is small compared to incandescent and compact fluorescent lamps, multiple diodes are often used together. In recent years, as diode technology has improved, high power light-emitting diodes with higher lumen output are making it possible to replace other lamps with LED lamps. One high power LED chip used in some commercial LED lights can emit 7527 lumens while using only 100 watts.[1] LED

Compact fluorescent lamps

Compact fluorescent lamps A compact fluorescent lamp (CFL), also known as a

compact fluorescent light or energy saving light (or less commonly as a compact fluorescent tube), is a type of fluorescent lamp

Constructiony The most important technical advance has been the replacement of electromagnetic ballasts with electronic ballasts; this has removed most of the flickering and slow starting traditionally associated with fluorescent lighting. y There are two types of CFLs: integrated and non-integrated lamps. Integrated lamps combine a tube, an electronic ballast and either an Edison screw or a bayonet fitting in a single unit. These lamps allow consumers to replace incandescent lamps easily with CFLs. Integrated CFLs work well in many standard incandescent light fixtures, reducing the cost of converting to fluorescent.

Components CFLs have two main components: a gas-filled tube

(also called bulb or burner) and a magnetic or electronic ballast Standard shapes of CFL tube are single-turn double helix, double-turn, triple-turn, quad-turn, circular, and butterfly. Electronic ballasts contain a small circuit board with rectifiers, a filter capacitor and usually two switching transistors connected as a high-frequency resonant series DC to AC inverter

High Intensity Discharge lamps

high-intensity discharge (HID) lamp is a type of

electrical lamp which produces light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz fused alumina arc tube This tube is filled with both gas and metal salts. The gas facilitates the arc's initial strike. Once the arc is started, it heats and evaporates the metal salts forming a plasma, which greatly increases the intensity of light produced by the arc and reduces its power consumption

The process begins with the cutting of straight glass shells.,

PROCESS OF MAKING CFL

The shells are bent into a u shape.

The tubes are washed in a chemically purified water at a temperature of 65-75 degrees centigrade .

After the wash the tubes are dried for about 25 minutes at a temperature of about 80 degrees centigrade

A coating of fluorescent powder prepared with a binder and purified water is then applied to the glass shells. The fluorescent powder is a combination of phosphor (containing calcium phosphate, aluminum oxide) and polyethylene oxide and dispersion agents

The tubes are dried and put in a baking machine that maintains a temperature of about 550 degrees centigrade. After three minutes the tubes are taken out and a fluorescent-whitening agent is applied

The filament is slipped inside the tubes

The ends of the glass tubes are cleaned and they are mounted on a sealing machine for locking the filament inside the tube

The tubes are vacuumed in an exhaust machine and mercury and argon are introduced into the tubes while the cathodes are heated

The tubes are sealed using a tipping machine and the electrical components such as the ballast are soldered with the tubes

The CFLs are capped with a plastic base and sent for uality checking that involves grading of CFLs based on their luminescence
