摘　　要：要提高LED光源及灯具的能效,应根据实际照明环境,对灯具进行最优化的配光设计,在满足照度要求的情况下降低功率密度,达到较好的节能效果。通过对不同配光的LED路灯的照明效果比较、以及LED路灯与高压钠灯的照明效果比较,验证了灯具配光曲线的设计对实现整个照明系统高能效的作用,给出更准确的LED光源及灯具能效等级评定方法。For improving the energy efficiency of LED light and luminaire,it is necessary to optimize their light distribution design according to the real lighting surroundings.In this way,power density and energy consumption can be further reduced while illuminance requirements are met.By comparing lighting effects of LED street lights with different distribution,high pressure sodium lamp and LED street light,it was verified that the light distribution design of LED luminaire is important for energy saving,and a scientific method for energy efficiency evaluation of LED lights and luminaires is given.
