摘　　要：本论文对LED户外显示屏的光污染问题进行了探讨，对LED显示屏的主要光污染，包括光入侵、眩光、显示屏亮度、夜空辉光等光污染，参照国际照明委员会（CIE）与上海市的限制标准，提出了LED显示屏的光污染的参考限制参数。针对显示屏的光污染，提出了器件级的解决方案。在有效可视范围内，光能量集中分布，有利于降低显示屏功耗，在无效可视范围内，尽量降低光能量分布，减少光污染。经过实测数据的对比，这个器件级的降低光污染解决方案，能有效降低无效可视亮度范围内10%～50%的光污染。In this paper, the light pollution of LED outdoor display is discussed. The main light pollution’s references limits , including light invasion, the glare, the LED display’s brightness and sky glow, is proposed. The LED package level solution of the display light pollution has been proposed. Within the valid visible range, the light energy is concentrated here, help to reduce the display power consumption. Within the invalid visible range, try to reduce the light energy distribution and light pollution. By comparison the data of the reduction of light pollution, LED package level solutions can reduce the brightness in the invalid visible range of 10%to 50%of the light pollution.
