Thermally efficient compact fluorescent fixtures

Abstract

This paper desaibes the development of thermally efficient compact fluorescent fuctures. Experimental data shows that decreases in fixture efficiency can approach 20% due to elevated temperature conditions inside the lamp compartment. These elevated temperatures inaease the minimum lamp wall temperature of the compact fluorescent lamp and reduce the light output and efficacy of the lamp ballast system.

Dirt depreciation of compact fluorescent lamp downlights

“…However, most compact fluorescent downlight fixtures present a highly constricted thermal environment to the temperature sensitive compact fluorescent lamp. According to previous studies the losses in lumen output can be as high as 20% [1][2][3]. One of the emerging techniques for mitigating the thermal losses is convective venting.…”
