摘　　要：LED广告屏的亮度是造成光侵扰问题的主要因素。我们调查了京津地区17处LED广告屏参数及其对周边居住建筑造成的光侵扰。展开针对不同设置条件下LED广告屏光侵扰模拟研究。设置条件确定为LED广告屏亮度、距受侵扰建筑水平距离、面积、与居住建筑水平夹角、以及与居住建筑垂直夹角五个自变量,以窗口受到25 lx的侵扰照度为基准,得出多变量共同影响下窗口照度的变化规律以及单一变量与窗口照度之间的相对关系。Previous studies have shown that the brightness of the LED advertising screen is the main cause of optical intrusion problems. The research includes the optical intrusion to the surrounding residential architectures with different setting conditions based on the parameters of 17 LED advertising screens in Beijing and Tianjin. The setting conditions is composed of five independent variables including the brightness and area of the screens,straight and level distance from the intrusive architectures,and both the horizontal and vertical angle of the architectures. The research is based on 25 lx intrusive illumination indicating the variation tendency of window illumination under multi-variable influence,and relationship between the single variable and window illumination.
