摘　　要：本文以LED路灯为例,实验测试了其PC透镜在紫外老化前后配光性能的变化,模拟计算了这种变化对道路照明效果的影响。结果表明,当PC透镜紫外老化时,其配光特性发生改变,相应地道路照明效果可能无法满足设计要求。建议有关标准应考虑紫外老化对LED路灯配光性能的影响。Taking LED street lamp as an example,the paper tests the changes of light distribution performance before and after UV aging,and the influence of such changes on road lighting effects is simulated.The results show that when the lens undergoes UV aging,its light distribution ability decreases,as a result the road lighting parameters may not meet the design requirements.The effect of UV aging on the light distribution should be considered in relevant standards.
