ABSTRACT:
The reflection surface of the reflector is composed of four segments depending on the low-beam light distribution pattern according to the ECE or SAE standard. For the ECE low-beam light distribution pattern, segment is part of a paraboloid of revolution; segment is a parellipsoid; reflector segment is a parellipsoid; and reflector segment is a general paraboloid. The various segments merge continuously and with smooth transitions with one another. For the SAE low-beam light distribution pattern, the reflector segment is a paraboloid of revolution; the reflector segment is a general paraboloid; the reflector segment is a paraboloid of revolution; and the reflector segment is a general paraboloid; in the SAE low-beam light distribution pattern as well, the reflector segments merge with one another continuously and with smooth transitions. The original beam of light produced by the various reflector surfaces of the reflector 1 is substantially equivalent to the low beam as allowed by law and that is suitable for the road surface, so that the dispersion plate can largely be dispensed with, or else can be inclined steeply or need have only a few optical devices.
