Study on Matching Value of Illumination in Night Lighting Environments

摘要

Night lighting plays an important role in the field of crime prevention. The horizontal illumination and the vertical illumination are important indicators to measure the proportion of crimes. In order to study the optimal match between the illumination of the exit plane and the illumination of the vertical plane in anti-crime lighting, 12 sets of LED light environment were set up in the residential area. Weber Fischer law is used to analyze the experiment, and the best matching relationship between horizontal illumination and vertical illuminance in the field of crime prevention at 4m is concluded. The experiment was analyzed with Weber-Faxler's law, and the best illumination matching relationship corresponding to the face clarity of 4m distance was obtained. The results are referential for crime prevention by means of night lighting.
