Abstract

LED is standing in the limelight as a light part of the low-carbon green energy. While LEDs are eco-friendly, efficient and durable, extreme heat rises can cause their durability to decrease, with 80% of the power supply being turned into heat energy. Heat radiation systems are important because rising temperatures affect the lifetime of LED elements. Therefore, in this paper, thermal analysis was performed for the shape of heat sink to the LED bulb. Also, it is applied the temperature control systems to our products for optimal performance.

LED는 저탄소 그린에너지 시대의 등기구로서 각광을 받고 있다. 다른 조명용 광원에 비해 친환경적이고 높은 에너지 효율을 가지고 있고 수명이 길다는 장점을 가지고 있지만, 공급전력 중 80%이상이 열에너지로 전환되며, 이에 따른 온도상승이 불가피 하여 높은 온도가 단점으로 꼽히고 있다. 온도상승은 LED소자의 수명에 영향을 미치기 때문에 방열시스템이 중요하게 자리 잡고 있다. 따라서 본 논문에서는 방열성능 향상을 위하여 LED 전구의 heat sink의 형상에 대한 열해석을 통하여 방열 시스템의 효용성을 분석하였다.
