Automotive headlight having optics in the reflector |
摘要 |
An automotive headlight has a clear unfluted front cover and a reflector which directs light from a source through the front cover in a desired pattern. The reflective surface is smooth and continuous formed of two edge ellipsoids and a center ellipsoid joined in smooth continuous junctions. The center ellipsoid is modified to include a smooth vertical bump and the ellipsoids are tilted off the axis of the headlight. The headlight is formed by a digital computer aided process which includes tracing the paths of a plurality of light rays emanating from a digitally modeled light source, intersecting a reflector modeled by digital shape functions and projected onto a sphere surrounding the reflector. The light intensity across a part of the sphere is compared with the prescribed automotive headlight specifications. The parameters of the shape functions are changed and the process is performed iteratively to produce a light intensity best matching the specifications.
