Understanding Heat Transfer Mechanisms in Recessed LED Luminaires
نویسنده
چکیده
Reduced maintenance cost due to the long life of light-emitting diodes (LEDs) has attracted the lighting community to this rapidly evolving lighting technology. A high LED junction temperature negatively affects the performance of LEDs. To realize the long-life potential of LEDs, proper thermal management is necessary. This paper describes a numerical and experimental investigation of thermal solutions for an LED recessed downlight under passive cooling. Different heat transfer mechanisms and their contributions for keeping the LED junction at lower temperatures also were analyzed.
