시뮬레이션을 이용한 반사판 재질에 따른 LED Module의 광학적 특성

LED have many problem as narrow light view angle, high price, drift phenomenon of color coordinate, high heating problem for lower power, lower weight and small size. But, with the development of blue LEDs and the improvement of LED brightness, color variation are becoming more and more popular as lighting and application devices in this page, I used the Light Tools which was a simulation program in order to recognize optical a few characteristic of LEDs arrangement along reflector matrial and designed LED Arranged 5 phi LED in 5㎜ interval in the square that was 10×10 And designs a reflection board on pcd, structural design of PCB changed as five type. - Aluminum, Gold. Chromlum, Nickel, Copper,
