摘　　要：从越野车野外夜间行车安全性出发,提出了越野车辅助驾驶灯的最低目标配光标准,并给出了满足该配光标准的光学系统设计方案。该方案采用自由曲面透镜,使光源经配光后在受照屏上的光照分布满足配光要求。仿真结果表明:采用15 000lm的LED光学照明系统性能能够满足文中提出的目标配光标准。From the consideration of off-road vehicle driving safety at night, a minimum lighting standard, as well as the optical design solution which can meet this standard, is proposed. The optical design solution uses a freeform surfaces lens to ensure that the light distribution can meet the requirement of the off-road auxiliary driving light standard proposed. The simulation result shows that the optical system can perfectly fulfill the standard with a 15,0001m LED light source.
