Abstract

A simple method is proposed to measure the heat dissipation of LEDs and fluorescent lamps in an open system which allows light energy to escape. Based on this method, a comparative study on the thermal and luminous performance of high-brightness LEDs and fluorescent lamps is presented. At rated power, T5 & T8 fluorescent lamps generate about 73%-77% of their total power as heat, whilst three types of highbrightness LEDs dissipate about 87% to 90% of input power as heat. Heat dissipation is an important factor particularly for airconditioned buildings when overall energy efficiency is considered. T5 fluorescent lamps perform better than some existing LEDs in terms of luminous efficacy and heat generation in this study. © 2009 IEEE.
