摘要(Abstract)：
本文提出了体育场四角塔投光照明逆过程设计方法。该设计分两步进行：首先，根据照明要求确定塔位、塔高以及单塔的光强分布；然后采用减灯法确定投光灯总数和它们的瞄准点。考虑到水平照度的均匀度并不很好，提出了一个水平照度梯度优化方案。本文还提出了如何建立瞄准点与投光灯布置关系的方法，同时详细描述了如何选择灯具以及瞄准点区域。最后根据逆过程投光照明设计方法，建立了一个体育场四角塔投光照明的计算机辅助设计系统。
In this paper, a method of the revezse order design for stadium floodli- ghting with for corner towers has been put forward. It consists of two steps. First, the location and height and a cardlepower distribution of each tower are predeternined in terms of the lighting requirements. Secondly, the sum of lumi- naires and their aiming points,re. determined by using de-lamp method. Conside- ring that the uniformity of the horizomel illuminance is not very we1l, the me- thod of optimizing the gradiant of horizontal i1luminance has been suggested. The method of establishing relation between the aiming points and the anange- ment of floodlights has been still put forward, and laow to choose kind of flo- odlight and the region of aiming points has been described in detail. At last, a computer aided design system has keen beveloped according to the reverse ord r floodlightimg design for stadium with four corner towers.
