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 8.6lm/W was obtained under 300mA.While the current is less than 700mA
the efficiency is larger than 7lm/W. The change of color coordinate is very small and the color index is between 75 and 85
