摘　　要：本文主要针对多维度低位路灯的能耗问题进行探究。本文首先对多维度低位路灯的照明方式进行分析,通过建立道路照明模型,根据反射原理初步得到了灯具照射的最佳照射角度,同时也说明了正逆向的照明方式相比传统照明方式更节能的原因;然后针对灯具的光学配光与结构配光进行分析,得到影响灯具出光效率的关键因素在于透镜出光面高度;接着对透镜出光面能量分布与有效出光面高度进行了实验测试,根据实验结果选取了最优出光面高度,对灯具进行了初步优化,将灯具效率提升了27%;最后根据降低出光口高度的思路设计了异形透镜,将灯具出光效率提升了113%。This article mainly focuses on the energy consumption of multi-dimensional low-level street lamps.The thesis first analyzes the lighting methods of multi-dimensional low-level street lamps.By establishing a road lighting model,the optimal illumination angle of the lamp illumination is initially obtained according to the principle of reflection,and it is also explained at the same time about the reason of why the forward and reverse lighting methods are more energy-efficient than the traditional lighting methods.The optical and structural light distribution of the lamps were analyzed,and the key factor that affects the light output efficiency of the lamps was learned to be the height of the light-emitting surface of the lens.The energy of the light-emitting surface of the lens was analyzed.The distribution and effective light-emitting surface height were tested experimentally.According to the experimental results,the optimal light-emitting surface height was selected,and the lamp was initially optimized,which increased the lamp efficiency by 27%.Finally,the special-shaped lens was designed according to the idea of reducing the height of the light-emitting port.The light output efficiency of the lamp has been increased by 113%.
