Abstract:
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.
