摘　　要：为提高现有室外篮球场照明光线利用率、降低眩光值,设计了一种偏光照明方案,避免光线照射到场地之外。通过对不同照明方案进行光学分析,找出光线利用率低的原因,并进行偏光设计使光线集中照射到场地内部。使用DIALux进行整体方案模拟分析:整体照度均匀度达到0.85,测出眩光值最大为29,远小于室外体育场眩光要求值50,其均匀度、眩光控制均能够满足各类比赛需求。计算得到光线利用率为75%,远大于现有照明方案的52%。与现有照明方案相比,该方案节能效果显著。In order to improve the light utilization rate of the existing outdoor basketball court lighting and reduce the glare value,this paper designs a deflected lighting scheme to reduce the light exposure to the outside of the field.Through optical analysis of different lighting schemes,the reasons for the low utilization rate of light are found,and the deflected light design is carried out to make the light illuminate the inside of the venue in a concentrated manner.DIALux is used for simulation analysis of the overall scheme:the overall illuminance uniformity reaches 0.85,and the measured glare value GR maximum is 29,which is far less than the outdoor stadium glare required value of 50.The uniformity and glare control can meet the needs of various competitions.The calculated light utilization rate of 75%is far greater than the 52%of the existing lighting scheme.Compared with the existing lighting scheme,the energysaving effect is significant.
