ABSTRACT:
The temperature of a fluorescent lamp is optimized by monitoring the current used to power the lamp and changing the cooling state (on to off, off to on) whenever lamp current increases. The optimum current level is some minimum value; any increases in this value are detected and a signal is fed back to a controller which regulates the instant mode of operation of a cooling device. With the cooling mode reversed, the lamp current will be reduced towards its optimum value. The cooling mode remains unaltered until the lamp current rises again. Thus the optimum temperature (minimum current to produce the required light level) is achieved without reference to either an absolute current or temperature.
