Abstract

Market for LED lights as a newly-growing industry has been growing, and secureness of high efficiency and long life through optimal thermal design are crucial for further popularization. In this study, considerable improvement in thermal performance for a 10W LED light has been done compared to a previous model. For this, numerical model has been established through experiments and used to optimize design factors in heat release such as fin shape, PCB kind or LED number etc. Furthermore, prototype of a LED light has been made and the improved thermal performance was verified with heat release experiments.

신성장 동력 산업으로 분류된 LED 조명등은 점차 수요가 확대되고 있으나 본격적인 대중화를 이루기 위해서는 여전히 LED 방열 설계 최적화를 통한 긴 수명과 고효율 확보가 매우 중요하다고 하겠다. 본 연구에서는 기존 10W LED 조명등에 비하여 방열 성능이 더욱 개선된 LED 조명등을 개발하고자 하였다. 이를 위하여 기존 램프의 방열 성능 실험을 통하여 수치해석 모델을 완성하였고 이러한 수치 모델을 이용하여 방열핀 형상, PCB 종류 및 LED 개수 등과 같은 방열 설계 인자들을 최적화하였다. 또한, 시제품을 제작한 후 방열 성능을 실험으로 검증함으로써 방열 성능이 획기적으로 개선된 10W LED 조명등을 성공적으로 개발하였다.
