摘要：近年来LED广告屏在城市中广泛使用，但居住区周图布置的LED广告屏在夜间对居民形成了强烈的色光侵扰。为了明确LED广告屏形成的色光侵扰程度及其防控措施，以北京、天津地区17处LED广告屏及受其侵扰的居住建筑为研究对象，展开主观问卷调查，并现场测试LED广告屏侵扰光的色坐标、亮度等参数，获得187份调查问卷及288组测试数据。道过对比分析主观问卷和测试数据，明确了LED广告屏的主要侵扰因素为LED屏与居住建筑的相对位置关系、LED屏侵扰光亮度水平及其数值变化和LED屏的光色交替变化，提取了各侵扰色光的波长及亮度数值范国，提出了对LED屏幕设置的建议。

Abstract: In recent years, LED advertising screens have been widely used in cities around China. However, LED screens have induced serious chromatic light trespass problem to residential area around. 17 cases of LED advertising screens and residential buildings affected in Beijing-Tianjin region are studied to make clear influence degree and control measures of the light trespass. The survey is conducted by subjective questionnaire and objective measurement, as LED screens are tested for color coordinates and corresponding brightness range. A total of 187 valid questionnaires and 288 sets of valid test data are collected. The questionnaire and test data show that 3 factors (relative location, brightness and its variation, colors change in rotation) is the key factors of intrusive effects. The range of wavelength and their corresponding luminance ranges for chromatic lights are summarized. Finally+ some design recommendations are provided concerningLED screens setting.
