摘　　要：重点对近年来白光LED的进展进行评述 。White LED has attracted considerable interest in recent years because of further improvement of “green lighting source” and micro solid state lighting source.It can be used for aerospace lighting, emergency and signal lighting,hazardous lighting,electronic signs,general industrial lighting.This paper considered the development of white LED for lighting source and compared our sample with foreign products.For the products of Nichia Corporation,the luminescent intensity is 5 5cd;the color coordinate is x=0 31,y =0\^32;the color index is 85.For the products of Opto Technology Inc.,the luminescent intensity is 0 5 cd;the color coordinate is x=0 26,y =0 25;the color index is 48.For our sample,luminescent intensity is 1 4 cd;the color coordinate is x=0 30,y =0 28;the color index is 89.
