Automotive Forward Lighting with Use of High Flux White Light-Emitting-Diodes 2006-01-0104

In general, an LED headlamp consists of an optical system, an electrical system and a mechanical system. Conventionally, the optics of a headlamp is a classical illumination set, which includes a light source, a reflective mirror and/or a lens. In this research, the source simulation, a reflector design and the propotype are presented. The application ways of the LED headlamp prototype include fog lamps, low beam lamps and high beam lamps, and overall with a light distribution that approaches the ECE regulation. Presently, the AFS (Adaptive Front Lighting System) is one of the strongest areas of development for the headlamp design, and the LED headlamp with the AFS function will be the leading trend in the next generation. Therefore, the LED headlamp design and AFS function are integrated to produce the prototype of the AFS-LED headlamp. Finally, the study will show that an optical system to provide the applicable possibilities for the adaptive front lighting system (AFS).
