Abstract

LED lights as a newly-growing industry are highly energy-efficient and have drawn lots of attention due to higher illuminance and longer life compared to other light sources. In this study, MR16 lights with one high-power LED were considered for the replacement of the previous halogen lights or LED lamps with many LEDs. Thus, fundamental experiments of LED on a MCPCB, 3-dimensional numerical analysis for heatsink design and performance tests of the prototype lights have been done and the MR16 LED lights have been successfully developed.

신성장 동력 산업으로 분류된 LED 조명제품은 고효율 에너지 제품으로 기존 광원보다 조도가 높고 수명이 길어 많은 주목을 받고 있다. 본 연구에서는 기존의 할로겐 MR16 조명등이나 다수의 LED를 사용한 MR16 조명등을 대체할 단일 LED를 사용하는 MR16 조명등을 개발하고자 하였다. 이를 위해 LED 패키지 MCPCB 장착 기초 실험, 3차원 방열 수치해석 및 시제품에 대한 방열 성능실험을 수행하여 성공적으로 고출력 단일 LED MR16 조명등을 개발하였다.
