Research on property of high-power white LED

Bin Gan, Jin Shangzhong

Abstract

The luminous intensity,luminous flux and color coordinate of high-power white LED have relations with different place.We analyze the factors,and bring forward solving method.Meanwhile,we also conduct an experiment on the change of luminous intensity,luminous flux and peak wavelength with current and time.From the result of the experiment,we know that the temperature has a serious effect on the high-power LED.
