摘要：

A new optical structure was designed for the developed LED headlamp. The far beam optical structure was realized with a free form reflector which collect as much as the light to satisfy the demand on light distribution for far beam; the passing beam was composed of three identical cells to ensure enough illumination and each cell have a LED with five 1w led chip packaged in line. A dissymmetry ellipsoidal reflector was used to concentrate the rays and a shade was employed to produce the cut-line. The optical performance was simulated with ASAP (advance system analysis program) and the results show a good agreement with the requirement for headlamp in national standard
