目前体育场投光照明都采用正过程设计方法，亦即从照明器布置进而计算照度。本文提出体育场四角塔投光照明逆过程设计理论，即根据照度分布来确定照明布置。为此建立了一个数学模型，假设塔上的投光灯都布置在一点上，且每个塔的水平照度分布具有下列形式： ＥＨ（ｘ，ｙ）＝Ｋ·ｇ（ ｘ）·ｆ （ｙ）本文详细描述了如何确定函数ｇ（ｘ）和ｆ（ｙ）以及塔位可容许范园，其范围与照明要求有关。
At present, stadium lighting lighting uses a positive process design method, that is, from the luminaire arrangement to calculate the illuminance. This paper puts forward the design theory of the reverse lighting process of the stadium’s four-point tower, that is to determine the lighting layout according to the illumination distribution. A mathematical model was established for this purpose, assuming that the floodlights on the tower are all arranged at one point, and the horizontal illuminance distribution of each tower has the following form: EH(x,y)=K·g(x)·f (y This paper describes in detail how to determine the functions g(x) and f(y) and the tower allowable range, whose range is related to the lighting requirements.
