Abstract：Among all the light sources of light trespass , LED advertising screen is one of the most typical chromatic light trespass sources due to the following concerns , including large luminous area , high luminance, great transient luminance variation difference , high color saturation and so on .The study is based on two surveys .One is the optical parameter data collected on light trespass effect by LED advertising screen through the window .The other is the subjective investigation of the surrounding residents .Through the above surveys , this paper analyzed typical chromatic light trespass around residential buildings caused by LED Advertising Screens.From the data collected in Tianjin, 7 cases in total, the study analyzed the spectral range of the typical chromatic light trespass , the range of the luminance and duration of light trespass.In conclusion, the study compared the data with the current code standard of lighting design , in order to determine the degree of typical chromatic light trespass .
