静态光侵扰对室内活动的侵扰阈值研究

用于道路、标识等功能照明的静态光源所产生的光侵扰影响居民室内活动.从居民的主观感受出发,通过主观评价实验,结合阈值的操作定义,计算正常室内照明情况下,静态光侵扰的2种常见光色(黄光、白光)、4种面积比(侵扰满窗、1/4窗、1/16窗、1/64窗)条件下的亮度侵扰阈值.结果表明,侵扰光亮度与侵扰程度成强相关;面积比与侵扰程度呈负的强相关;进而得到亮度阈值与侵扰面积比的幂函数关系式.

Study on the trespass threshold of static light trespass on indoor activities of residents

Research shows that light trespass produced by static light sources for functional lighting such as roads and signs affects residents'' indoor activities. Through subjective evaluation, the experiment based on the subjective feelings of residents was carried out combining, with the operation definition of threshold, and the luminance trespass thresholds of two kinds of light colors (yellow and white light), four area ratios (trespass full windows, 1/4 windows, 1/16 windows, 1/64 windows) of urban static white light trespass with normal indoor lighting conditions were calculated. The results show that the intensity of trepass is closely related to the dregree of trespass, the area ratio is negatively correlated with the degree of trespass and a power function equation of the luminance threshold and area ratio is obtained.
