히트파이프 방식의 LED 보안등용 방열장치에 관한 연구

다국어 초록 (Multilingual Abstract)

With the advantages of power saving, increased life expectancy and fast response time over traditional incandescent bulb, LEDs are increasingly used for many applications including automotive, aviation, display, transportation and special lighting applications. Since the high heat generation of LED chips can cause a reduction in lifetime, degradation of luminous efficiency, and variation of color temperature, studies have been carried out on the optimization of LED packaging and heat sinks. In this study, a heat pipe type cooling device, instead of a solid aluminum heat sink, was designed for LED security lightings. And numerical analysis was carried out to evaluate its cooling performance.
