| 中文摘要: |
| 为进一步优化传统反光杯在匀光、防眩光等方面的问题，基于Zemax仿真软件设计出了一种匀光性能优越的鳞甲反光杯。仿真结果表明，在杯前25 m处的配光屏幕上，最大光照强度为234 lx，中心HV点的光照强度大于0.80 Emax，各指标均符合国标GB 25991—2010《汽车用LED前照灯》的要求。将鳞甲反光杯与微透镜阵列相结合，使配光屏幕上的最大光照强度减小至59.51 lx，在各项指标仍符合国家标准的情况下，该系统的光斑能量更加均匀，且中心区域的光强进一步降低，光斑边缘过渡更加柔和，防止汽车远光灯产生眩光的效果更好，可以大量应用于汽车前照远光灯。 |

| In order to further optimize the traditional reflective cup for uniform light, anti-glare and other aspects of the problem, a new reflective cup based on Zemax is designed. The simulation results for using the squamous reflective cup show that the maximum light intensity at the front 25 m of the reflective cup is 234 lx, and the light intensity at the center HV point is greater than 0.80 Emax. All indicators meet the requirements of the national standard GB 25991—2010 automotive headlamps with LED sources. The squamous reflective cup can also combine with the micro-lens array. While meeting national standards, the spot energy is more uniform. The central area of light intensity has been further reduced, and the spot edge transition is more smooth. The effect of preventing glare from high beam is better. The system can be widely used in automobile headlamp. |
