Simulation and Analysis of Free-form Head-lamp's Low Beam Distributing

Anti-dazzling is a key technology for automobile safety, at the same time, it is also a world problem which had not been well resolved. This paper discusses the development of free-form head-lamp, the regulation on low beam distribution which stipulated by ECE and the theory of ray-trace. This paper builds a free-form reflector using the software REFLECTORCAD and builds linear lamp-house to trace rays by the software TRACEPRO,and has gained real distributing of free- form reflector on the distribute-screen.
