摘　　要：为研究路灯布置对道路交会区的照明影响,本文首先对南京市区内常见的3种道路交会区的照明现状进行分析,然后针对交会区各自特点及照明现状提出了改进后的布灯设计方案。最后,通过照明软件DIALux的模拟计算分析,有效验证了所提优化方案的可行性。结论表明:对于小型交会区,应尽量避免使用中杆灯及泛光灯灯具,避免过度设计;对于中型交会区,应考虑路口的补充照明,兼顾道路的过渡段;大型交会区应考虑道路转弯处的照明,同时为考虑整体的均匀度,应酌情提高灯杆高度。In order to study the influence of street lamp layout on the lighting of conflict area,this paper first analyzes the current lighting situation of three common conflict areas in Nanjing urban area,and then puts forward an improved layout design scheme according to their respective characteristics and lighting status.Finally,the feasibility of the proposed optimization scheme is effectively validated by the lighting software DIALux.The data reveals that for small conflict areas,the use of medium pole lamps and floodlight lamps should be avoided as far as possible,and excessive design should be avoided;for medium-sized conflict areas,supplementary lighting at conflict areas and transition sections of roads shall be considered;the lighting at the turning of the road shall be considered for large intersection areas,and the height of the light pole shall be increased as appropriate to ensure the illuminance uniformity.
