LED 조명용 2단 반사컵의 최적 설계

초록

In order to reduce the design errors in beam patterns of LED reflector, we had analyzed the change of beam pattern which depend on the light distribution of LED surface. And the analysis results were applied to the optimum design for the 2 step LED reflector. By combining the crossed and uncrossed type reflector, especially, we were able to control the maximum intensity and the beam angle of the radiation beam patterns.
