Abstract :
A series of prototype fixtures that employ convective venting and heat sinking to reduce elevated lamp temperatures is described. Experimental data show that decreases in fixture efficiency can approach 20% due to elevated temperature conditions inside the lamp compartment. The elevated temperatures increase the minimum lamp-wall temperature of the compact fluorescent lamp and reduce the light output and efficacy of the lamp ballast system. It is shown that the cooling strategies can produce 20% increases in light output and efficacy.<>
