中文摘要： 从居住建筑窗口进入室内的室外照明侵扰光会对居住者的生活与休息产生严重干扰，甚至影响到居住者昼间的工作。这一问题是目前居民关注最多且研究难度较大的一类光污染。本项目研究对指导居住区光环境设计、科学检测评估侵扰光的影响、提高居住质量有重要意义。本项目主要以城市中典型居建筑窗口受到的侵扰光为基本研究对象，在大量测量居住建筑周边光环境及建筑窗口受到的侵扰光的光度参数的基础上，建立研究基础数据库。通过统计分析，建立典型评价模型，提取出用于评价实验的侵扰光面积、侵扰光亮度、色彩等评价参数。并在实验室内设计并建造可调节上述光参数的实验空间，展开对人员在实验空间中休闲状态的影响程度的实验研究，从而得出不同评价光参数的亮度阈值，为居住建筑夜间室内侵扰光的规范标准制定以及道路照明、景观照明的设计标准修订提供基础研究数据。

英文摘要： Light trespass, which comes into the interior through the residential buildings' windows, would seriously interfere the residents' life and rest, even the daytime work. That has became the most concerned problem, also isone of the light pollutionaspects which isdifficult to research. For guiding the design of residential lighting environment, scientifically estimating the influence of light trespass, improving the residential quality, the research has to be carried out. The project mainly researches the light trespass from the typical dwellings' windows in the city. On the basis of measuring the lighting environment of massive dwellings and the photometric parameters of corresponding light trespass, the research database can be established. Through the data analysis, evaluation model which contains the ratio relationship of light trespass area, the intensity of light trespass, brightness, color and other evaluation parameters can be acquired. Then an experimental space will be set upwhich can regulate theabove parameters. Through the laboratory research, the impact of subjects under different statuses, such as leisure, can be studied. After that, the limitations of evaluation parameters can be obtain. This research will provide basic data for formulating the standard of light trespass of residential buildings.
