摘　　要：本文主要利用白光LED单管制备了白光LED面阵 ,将制备的白光LED面阵与日亚公司的同类产品进行了对比。研究了不同电流条件下 ,亮度、流明效率、色坐标和显色指数的变化。The white LED matrix was fabricated.The brightness,efficiency, color coordinate and color index were measured.The parameters of the white LED matrix were compared with that of Nichia. The maximum efficiency of 8 6 lm/W was obtained under 300mA . While the current is less than 700mA, the efficiency is larger than 7 lm/W. The change of color coordinate is very small and the color index is between 75 and 85, when the current changes from 100mA to 1000mA.

关 键 词：白光LED 色坐标 显色指数 面阵
