PREAMBLE TO THE DESCRIPTION
The following specification describes the invention

The present invention relates generally to apparatu s for handling electrical components.
Compact Fluorescent Lamps (CFL) is basically a low discharge lamp. Basically compact fluorescent lamp contains two major parts, sealed capsule and ballast. Sealed capsule is basically where electronic discharge happened and ballast feed the power to the capsule by generating rated high voltage. There are two types of CFLs are available at market. One is retrofit type CFL and other one is non-retrofit type. In case of retrofit type CFL ballast is included in the lamps and housed by plastic base and aluminum cap and the ballast is electronic ballast which generates high frequency to make quick discharge of electron in the capsule. In case of non-retrofit type CFL ballast is not included in the lamp, ballast is fitted in the luminaries and the ballast is magnetic ballast, which generate high voltage across the capsule to make electronic discharge in the capsule. After making of the lamps each type of CFLs has to aged and test for a specified time frame before sending to market. Aging is basically the process in which electrical parameters like wattage, filament current, lumen output are stabilized to give the rated parameters after continuos burning of lamps for a specified period.
Traditionally the process of aging is done by loading the lamp on the aging conveyor, testing the same and unloading the lamp from the conveyor. Wherein the aging process is to be done for both retrofit and non-retrofit CFLs. For conducting mass aging of CFLs linear horizontal conveyors are used. The traditional system includes major drawbacks such as cost implications for getting two getting separate conveyors for retrofit and non

retrofit type, increase in use of man power to handle two separate conveyors, investment of time factor to a considerable amount and many more.
To overcome the above mentioned drawbacks an invention is presented herewith an electric holder for aging of non- retrofit lamps in the same conveyor used for retrofit type of compact fluorescent lamp.
An object of the invention is to provide an electrical holder which can be used for aging process for both retrofit and non-retrofit lamps in the same conveyor.
Another object of the invention is to provide an electric holder for again process, which can save significant time by reducing the loading and unloading of the product on both the conveyors.
Yet another object of the invention is to provide an electrical holder, which can reduce the investment of manpower on both the conveyors to single conveyor.
Another object of the invention is to provide an electrical holder, which can significantly reduce the capital investment on two conveyors to one conveyor.
Another object of the invention is to provide a holder, which can be used anywhere for testing the non retrofit CFLs at any places where luminaries is not available.

In accordance with the invention, a preferred embodiment of the invention is disclosed herewith comprising an aging conveyor typically used for testing retrofit lamp, made up of a plurality of the carrier blocks connected to the links of a pair of parallel roller chains. As the lamp moves down the conveyor an electric current is periodically passed through for the purpose of aging the lamp to cause the requisite chemical reaction within the bulb. Any defective lamps may be visually detected and can be segregated at unloading point of the aging conveyor. The linear aging conveyor for retrofit lamps is basically a linear aging conveyor moving in one direction. The conveyor consists of number of base plates. The base plates are connected on a chain. The chain is driven using an electrical motor. Controlled electrical supply is given to aging conveyor's phase plate and neutral plate through variac and control panel. There is a brush contact in the lower part of each and every holder. While conveyor is in motion the brush contacts touches phase plate and neutral plate. So during that time power is transmitted to the holder through brush contact. There are different voltage zones like low voltage (150Volt), nominal Voltage (230Volt) and high voltage (275 Volt) are available at the aging conveyor. So while moving the conveyor lamps will pass through law voltage, nominal voltage, high voltage zone and lamps get aged. Loading and unloading zone is available at the conveyor. Operators load the lajnps at loading zone and get it unload from unloading zone.
In accordance with the invention, the aging conveyor for the process of aging of the retrofit CFL includes a base plate with a holder for retrofit lamp attached to it. In concurrence with the base plate, magnetic ballast can be mounted on it with an additional upper plate. The upper plate in turn is attached with the holder for Non-Retrofit lamp.

For aging of the non-retrofit type CFLs we have to fit the new developed electrical holder into the holder of retrofit holder. The developed electrical holder consists of three parts. One is adapter, which will be fitted into the holder of retrofit type aging conveyor. Electrical power will transmit to the next part (Ballast) from aging phase plate through this holder. Second part is ballast. The input of the ballast is connected with the part one for getting the electrical power. Ballast will raise the required voltage to ignite the lamp and also limit the inrush current through the circuit. The output of the ballast is connected to the non-retrofit type lamp holder, which is mounted upward.
Last part is the holder for the non-retrofit type holder. The input of the holder is connected to the output of the ballast. Non retrofit type lamps are placed on this part and lamp will get the supply from ballast through top holder.
