At forward voltage V f=3.5V, forward current I f=20mA, and room temperature, the luminous intensity of the white LED is 1cd, and the chromaticity coordinate of CIE (x,y) (0.31, 0.38), which is near to the pure white (0.33,0.33).

• 在室温 ,正向电压 3 5V ,正向电流2 0mA时 ,W LED轴向亮度为 1cd,CIE色坐标为 (0 3 1 ,0 3 8) ,接近纯白色 (0 3 3 ,0 3 3 )。
