摘　　要：本文采用了一种结合灯具配光设计与道路照明设计的方法,针对特定路段进行优化。依托一种大功率且高功率密度的小型化、轻量化单颗集成式光源的LED路灯,其在光学性能和热学性能上表现优异,成功实现了长沙市某路段的LED照明节能改造。实际照明效果与道路照明设计软件模拟结果相吻合,主路平均照度(average illuminance,E_(av))由31 lx提升到39 lx,比改造前提高了23%;主路照度均匀度(Uniformity of Illuminance,UI)由0.45提升到0.8,比改造前提高了82%,且主路部分照明功率密度(Lighting Power Density,LPD)由0.89 W/m^(2)降低至0.36 W/m^(2),减小了60%;十字路口部分的LED投光灯升级改造,该路段整体节能率高达66%,阈值增量(Threshold Increment,TI)值仅为0.42%,照明舒适度大大提高,且大大延长了灯具的生命周期,具有很好的道路照明节能改造参考价值和市场推广前景。This paper adopts a method that combines luminaire distribution design with road lighting design,optimizing for specific road segments.Leveraging a high-power,high-power density,compact,and lightweight integrated light source LED street light,which demonstrates excellent optical and thermal performance,a successful energy-saving renovation of LED lighting was achieved for a road segment in Changsha.The actual lighting effect align with the simulation results from the road lighting design software.The average illuminance(E_(av))on the main road increased from 31 lx to 39 lx,a 23%improvement.The uniformity of illuminance(UI)on the main road rose from 0.45 to 0.8,an 82%increase.Additionally,the lighting power density(LPD)on the main road decreased from 0.89 W/m^(2)to 0.36 W/m^(2),a reduction of 60%.For the upgraded LED floodlights at the intersection,the overall energy-saving rate for this section reached 66%,with a threshold increment(TI)value of only 0.42%.The lighting comfort level significantly improved,and the lifespan of the fixtures was greatly extended,providing valuable reference for energy-saving renovations in road lighting and strong market promotion prospects.
