Abstract

Thermal management of light sources based on Light Emitting Diodes technology is a fundamental issue that can significantly affect the performance and life time of installed lighting products. By conducting an experimental study, this paper focuses on the vital role of passive cooling method in thermal management of low-power SMD LEDs Light bars. The used approach in this work aims to give an appropriate model to evaluate the thermal resistance of the heat sink. In order to optimize the cooling performance of a heat sink, it is recommended to minimise its thermal resistance as same as improve its cooling capacity since the thermal resistance impact the total resistance of LED package. In addition, the experimental measurements associated to the LEDs’ illuminances and temperature distribution are made using advanced equipment such as digital luxmeter, and IR camera, respectively, which the results are analyzed by Raycam reporting System software in real time.
