Abstract

Since LED lights have advantages of long life, low-carbon and high efficiency, they have been widely used as household lamps, automotive lighting, traffic lights etc. In this study, MCPCB LED lamps for automotive LED headlights were manufactured and the performance of heat release was optimized. The developed LED headlight satisfied the target thermal performance with heat pipes and fans, and it was also shown that fan life can be prolonged three times by fan on-off control.

LED(Light Emitting Diode) 조명기기는 장수명, 저탄소, 고효율의 장점을 가지고 있어 현재 가정용 램프, 자동차 조명등, 신호등에 널리 사용되고 있다. 본 연구에서는 자동차 LED 전조등용 MCPCB LED를 제작한 후 방열성능 최적화를 수행하였다. 개발된 LED 전조등은 히트파이프와 팬의 조합시 목표 방열성능 달성이 가능하였고 팬의 on-off 제어를 통해 팬의 수명 또한 3배 정도 연장 가능함을 보였다.
