摘　　要：综合性体育场馆的场地照明存在灯具数量多、使用率低、初投资大等问题,基于此,对标Ⅴ级照明标准,以耗电量为优化目标,选择贪心算法,提出针对手球场地的灯具位置和投射角度优化方案。基于现有灯具,进一步提出针对篮球、排球场地灯具开关数量及投射角度优化调节方案。以“十四运”某场馆为例,相比于人工布灯,优化设计后手球场地LED灯具数量减少16盏,总功率下降19416 W,耗电量减少26%,篮球、排球场地灯具耗电量分别下降31%和56%。可见基于贪心算法的照明系统优化设计可以有效减少场地灯具数量,不同比赛项目间灯具优化调节提高了灯具利用率,不但节约了前期购置及安装成本,而且在后期运行阶段节能效果显著。In comprehensive gymnasium,the lighting system suffers from disadvantages such as large number of lamps,low utilization rate,and large initial investment.Based on this,according to the class V lighting standard,taking power consumption as the optimization goal,and choosing a greedy algorithm,we propose an optimization scheme for the position and projection angle of lamps for handball courts.Furthermore,based on the existing lamps,an optimal adjustment scheme for the number of switches and projection angles of lamps in basketball and volleyball courts is proposed.Taking the venue of the 14th National Games as an example,compared with artificial lighting,the number of lightemitting diode lamps in the handball venue is reduced by 16,the total power is reduced by 19416 W,and power consumption is reduced by 26%.The power consumption of lamps and lanterns in basketball and volleyball courts is decreased by 31%and 56%,respectively.The optimized lighting system based on the greedy algorithm can effectively reduce the number of field lamps.The optimal adjustment of lamps between different competition events improves the lamputilization rate,thereby reducing the early purchase and installation cost as well as considerably saving energy in the later operation stage.
