摘要：

An effective high-efficiency LED headlamp system for automotive low-beam lighting which consists of parabolic reflector, compound lenses and combined prisms, is introduced in this paper. Using a single, high-brightness LED, the illumination requirements for a headlamp low beam specified by UNECE regulation Addendum 111: Regulation No. 112 Revision 2' can be achieved. On the test screen at a distance of 25m, simulation results as well as testing results for the prototype meet the requirements of the UNECE regulation for all specified regions and key points.
