【摘要】：在多车道的道路照明中,需要非对称矩形配光。本文根据非成像光学理论,建立点光源空间与目标照明面之间的拓扑关系,采用合适的反馈优化方法,获得面向扩展光源且在路面上形成均匀非对称矩形光斑的反射器,仿真结果表明,配光后光源的能量基本上被限制在20m×12m的矩形区域内,且实现了非对称的配光,横向照度均匀度达到了85%,纵向照度均匀度达到了80%,满足道路照明要求;并且通过开模实际测试出整体的照度均匀度为80.13%,验证仿真结果以及证明了设计方案的可行性和反射器在路灯灯具中的实用性。
[Abstract]:In multi-lane road lighting, asymmetric rectangular lighting is required. Based on the theory of non-imaging optics, the topological relationship between the point light source space and the illumination surface of the target is established. A reflector facing the extended light source and forming uniform asymmetric rectangular spot on the road surface is obtained by using the appropriate feedback optimization method. The simulation results show that the energy of the light source is basically limited in the rectangular region of 20m 脳 12m after the light distribution, and the asymmetrical light distribution is realized. The horizontal illumination uniformity reaches 85m and the longitudinal illumination uniformity reaches 80 percent, which meets the road lighting requirements. The illumination uniformity of the whole system is 80.13, which proves the feasibility of the design and the practicability of the reflector in the street lamp.
