摘　　要：从汽车前照近光灯GB25991—2010标准出发,提出了一种LED近光灯的设计方案.该方案采用外表面为自由曲面的透镜及反射面为自由曲面的反射器,使光源经配光后在受照屏上的光照分布满足配光要求。结果表明:采用200lm的LED光学照明系统性能能够满足GB25991—2010标准对汽车前照近光灯光照分布的要求。该系统具有高光学效率、外形紧凑的优点。A design of LED dipped headlight is proposed matching GB25991--2010 standard. Lens and reflector with free form surfaces are used to distribute the light in order to meet the requirements of the national standard. The result shows that the optical system can fulfill the requirements perfectly with a 2001m LED light source. Meanwhile, the optical system has very high efficiency as well as a compact structure.
