Abstract

A high power LED which is being used in many illumination applications as a new light source was simulated for its physical structure and then its optical properties were analyzed. To obtain accurate results from the designed LED model, properties of the die chip and reflector cup were varied. As a result, a high power LED model which has a radiation pattern of a Lambertian with its viewing angle of approximately $140^{\circ}$ and total included angle of $160^{\circ}$ was designed.

새로운 광원으로 각종 조명장치에 응용이 되는 고출력 LED 광원의 물리적 구조로부터 시뮬레이션을 통하여 광학적 특성을 분석하였다. 설계한 LED 광원이 신뢰할 수 있는 결과를 얻기 위하여 die chip과 reflector cup의 구조적 특성을 변화시켰으며. 그 결과 Lambertian 형태의 배광 분포를 가지며. 반치 폭(Viewing angle)은 $140^{\circ}$, Total Included Angle은 $160^{\circ}$를 갖는 고출력 LED 광원을 설계하였다.
