摘要
对常州万达广场的LED 屏进行测量，结果显示水平照度在距离 LED 电子屏水平距离10～25 m处出现波峰，而后递减；垂直照度在5～30 m 处出现波峰，而后递减。研究发现当LED 显示屏以低纯度、高亮度的颜色作为主色时产生较高的照度；从LED显示屏夜间亮度的控制、播放影片的色彩设计、 LED显示屏的安装3个方面提出LED 显示屏的光污染防治措施。
According to the measurement on LED screen of Changzhou Wanda Plaza, the horizontal illuminance reaches the peak at a horizontal distance of 10 to 25 m from LED electronic screen and then decreases progressively; the vertical illumination reaches the peak at a place 5 ~ 30 m away from the screen and then decreases progressively. According to studies, high illuminance will be generated when LED display screen uses colors with low purity and high luminance as the main color. Measures for control of light pollution of LED display screen are proposed in terms of brightness control of LED display screen at night, color design of played videos and installation of LED display screen.
