城市照明色光对居民室内活动的干扰阈值

城市照明的发展与LED的广泛使用致使居住区室外光环境日益明亮,且常见彩色光,居民的室内休闲娱乐活动所受到的影响也日见显著。从居民的主观感受出发,通过主观评价实验,得出正常室内照明情况下城市照明色光对居民看电视的干扰阈值,包括表征居民视觉感知的"明度阈值"和表征光源实际情况的"亮度阈值"。讨论了城市照明色光对居民室内活动干扰的季节差异、性别差异和色调差异,并对阈值结论的应用性进行了讨论。

Threshold of the disturbance to residents indoor activities by colored light from urban lighting

The development of urban lighting and the widespread use of LED have led to increasingly bright outdoor light conditions, common colored light in residential areas and increasingly impacts on residents'' indoor recreational activities before curfew. From the perspective of residents'' subjective feelings, the subjective evaluation experiment results in the interference threshold of urban colored light on residents'' watching TV activities under the condition of normal indoor lighting, which includes the "lightness threshold" characterizing residents'' visual perception and the "brightness threshold" characterizing of light source reality. This paper analysed that the seasonal difference, gender difference and hue difference of urban lighting color interfered with residents'' indoor activities. And the applicability of threshold conclusion was also discussed.
