Abstract

A projector headlamp comprised at least a reflector, shield and a (projection) lens. The reflector is designed by the multi-ellipsoid equation to shape a free curved surface, to produce a wide pattern for use. There is an excellent bevel angle design on the shield's right side. A projection lens is an aspherical surface, its curves of the axial cross-section is made by 4 dimensional equations. Thus a new projector headlamp with a best photometric pattern, a sharp cut-off line is created and it absolutely can meet severe international certification requirements.
