体育场四角塔投光照明的逆过程设计理论

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。

ROD Theory for Stadium Floodlighting With Four Corner Towers

Presently, stadium floodlighting is projected by the method of the obverse order design, which calculates the illumin anc distribution in terms of the lighting arrangement.In this pa- per,a theory of the Reverse Order Design (ROD ) for stadium floodlighting With four corner towers has been put forward, which determines the lighting arrangem.ent in terms of the ill- uminance distribution.A mathematical model has been establi- shed, which supposes that all floodlizhts on a tower are arr- anged at one point and that the horizontal illuminance distri- bution of each tower is given by: EH (x,y).==k. g (x). f (y) How to determine the functions of g (x ) and f (y ) has been described in detail,and the acceptable location of tower has been delimited in this paper, which is related to the lighting requirements.
