摘要
Light pollution becomes more and more serious, but the study on this field is far from enough. In this paper, light environment is defined as light-free area, dark area, intermediate sight area, and bright area. In addition, it is marked with index value by index system, which includes average brightness, brightness evenness, glare index, and background brightness.
