Night lighting has become an important environmental assets of the city,high-quality night lighting can better serve the city,serving the city residents in the nightlife.This study came into being in this context,and it is a quantitative study of how the light intrusion caused by the urban illumination shade affects the inhabitants.More specifically described as "a clear color tendency of the color of light,the residents in the visual environment for recreational activities,the visual effects of visual and psychological effects of interference." This paper aims to lay the foundation for effective prevention and control of light intrusion,in order to ultimately enhance the quality of night lighting.This paper combs the related research on the quantification of shade intrusion,clarifies the complexity and influencing factors of the research.The field research of the multi-city is carried out,and the database is established.The structural model of the light infiltration evaluation system is established,and the intrusion factors And the experimental method for subjective evaluation of color light intrusion in laboratory was extracted.Finally,the threshold of interference assessment of typical color light intrusion was obtained by quantitative analysis of large number of experimental results.The structural models of light intrusion assessment system are composed of "intrusion source","intrusion factor" and "intrusion form".The four kinds of intrusion sources are: point,static surface,dynamic surface and mass light source.Five kinds of intrusion factors are brightness,Light color,dynamic form,light-emitting time,light-emitting area;3 major forms of intrusion: brightness intrusion,color light intrusion,dynamic intrusion.The structure model of light intrusion evaluation system is the combing of the complexity of light intrusion,and the evaluation of complex optical intrusion is realized.The depth of research is from the qualitative research to the quantitative research stage,which is the theoretical innovation of this thesis.The method of color-light intrusion evaluation is to sort out the three related experimental methods by combing the threshold of psychophysics: limit method,constant stimulus method,and Likert scale method,which are proved by contrast and pre-experiment.It is applied to the experimental method of colorless intrusionevaluation experiment in non-straightforward state,which ensures the scientific rationality of the experiment and further establishes the basis of quantitative research of light intrusion.It is the innovation of the method.Interference with typical shade intrusion on indoor activities The threshold of assessment is the interference of six hue(red,yellow,green,cyan,blue,and purple) shades under three infiltration area levels(Sw / Sl = 1,4,16) Threshold.In this paper,we discuss the relationship between the interference threshold and the area of intrusion and the difference of season,sex and tone,and then discuss the application of threshold.Threshold research is the most important innovation in this paper.Quantitative research of light intrusion is the only way to solve the problem of light intrusion.This paper has laid the data foundation for the follow-up research,provided the scientific method and the experimental scheme,expanded the depth and breadth of the research,and finally got the quantitative results of light pollution control,prevention and control measures have a certain guiding significance.
