초록

LED조명장치는 자동차분야, 항공, 디스플레이, 전송장치 그리고 특수조명등의 응용장치로의 활용이 증가하고 있다. 일반적으로 고출력 RGB 멀티칩 LED는 표시용이나 경관조명용 또는 감성조명용으로 적용되고 백색 LED는 표시용 조명에서 최근 들어 일반조명용으로 적용되고 있으며, 고출력 백색 LED의 출시와 광효율의 증가는 이를 더욱 가속화하고 있다. 본 논문에서는 백색 LED와 RGB 멀티칩 LED 조명장치를 동일한 사양으로 제작하여 물리적, 전기적, 광학적 조명특성을 분석하여 향후 LED조명시스템의 제작에 정량적 데이터를 제공하고자 한다. 이를 위해 LED의 주요한 물리적 특성인 방열특성에 대한 성능분석, 전기적 특성의 분석을 위한 전력 및 드라이브 효율에 대한 성능분석을 수행하였고 조명특성을 위한 연색성, 배광특성, 광효율을 측정하였다. 백색 LED와 RGB 멀티칩 LED 조명장치를 활용한 응용장치의 적용방법을 확립하고 나아가 다양한 조명시스템에 LED 조명장치를 적용하는데 참고가 되는 기초 데이터를 제시하고자 한다.

LEDs are increasingly used for many applications including automotive, aviation, display, transportation and special lighting applications. Generally, the RGB multichip LED luminaire applied to signboard, emotional lighting system and display device and the white LED luminaire applied to general lighting system. white LED spectra for general lighting should be designed for high luminous efficacy as well as good color rendering. This paper describes characteristics of LED luminaire white LED and RGB multichip LED. Two type of LED luminaire prototype used experiment physical, electrical and optic test and performance analyzed. RGB multi-chip and phosphor-type white LED luminaire were analyzed by experiment on their color characteristics and luminous efficacy of radiation, distribution curve, and electrical characteristics. Research work is in progress to develop an improved performance for optic and electrical works well for two type of LED luminaires.
