近年来LED广告屏在城市中广泛使用,但居住区周围布置的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。通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围,提出了对LED屏幕设置的建议。
LED advertising screen in recent years, widely used in the city, but the layout of residential areas around the LED advertising screen at night residents formed a strong shade of light. In order to clarify the degree of shade of LED light screen and its prevention and control measures, taking 17 LED advertisement screens in Beijing and Tianjin area and its invaded residential buildings as research objects, a subjective questionnaire survey was conducted and on-site testing of LED advertising screen intrusion light Color coordinates, brightness and other parameters, access to 187 questionnaires and 288 sets of test data. Through comparative analysis of the subjective questionnaire and test data, it is clear that the main intrusive factors of the LED advertisement screen are the relative positional relationship between the LED screen and the residential building, the brightness level of the LED screen invaded and its numerical change and the light color of the LED screen are alternately changed, The wavelength of intrusion of color and brightness of the numerical range, put forward the recommendations of the LED screen settings.
