摘　　要：基于LED体积小、窄光束的特点,提出采用复合抛物面收集器(CPC)将LED发出的光收集起来再通过探测器测量其光通量值。采用Tracepro软件建立系统模型,模拟不同角度光线和不同光束角的LED测量结果;在软件模拟的基础上建立实验装置,在此装置上测量7只LED样品,测量结果与光通量绝对测量法进行比较。测量结果表明,该方法可以达到较高的精度。A novel method is presented to measure LED′s luminous flux due to its small size and narrow beam.A compound parabolic concentrator is used to collect the lights from a LED in conjucntion with a detector which in turn measures the luminous flux.The feasibility is validated by simulating single ray with different angles and 3 types of LEDs with software simulation analysis.Furthermore,7 LED samples are tested and the performance comparisons with goniophotometer are performed,and the results demonstrate that t...
