摘　　要：色温是影响LED路灯性能的一个重要因素,但对于色温分布均匀性的测量及评价尚未有明确的规范与指标。对3种典型结构的LED路灯进行空间相关色温分布测量,比较分析它们的相关色温分布均匀性的特点。通过对造成LED路灯相关色温分布均匀性差异的原因进行简要分析,指出单颗LED的相关色温分布是造成LED路灯相关色温分布差异的主要因素,并提出改善方法,以期为LED路灯的设计和评价提供依据。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.
