Research on the Uniformity of Correlated Color Temperature Distribution of LED Street Lamp
Abstract：Color temperature is one of the important factors that affect the performance of LED street lamp. But there has never been a criterion for the uniformity of color temperature. The spatial distributions of correlated color temperature （CCT） of three types of LED street lamps with typical structure are measured to compare the uniformity of CCT of these lamps. Through the analysis of causes for the different CCT uniformity of LED street lamps, it is pointed that LED street lamp＇s CCT distribution is mainly determined by the CCT distribution of single white LED. The solutions to improvethe Uniformity are given to provide the basis for the design and evaluation for LED street lamp.
