The light output of a fluorescent lamp is controlled and optimized. The light output of a lamp peaks at some optimum value of mercury cold spot temperature. During operation the lamp output is continually monitored, any drop in peak light output is detected, and a signal is generated which reverses the instant mode of operation of a cooling device placed in proximity to the lamp cold spot. With the cooling mode reversed, the light output will rise towards the peak. The cooling mode remains unaltered until the light output falls again. |
