| 摘要 |
The invention relates to a reflector for a motor vehicle headlight comprising a reflecting quadric which is substantially in the shape of a paraboloid of revolution intersected by upper and lower segmenting planes, an electrical lamp filament being placed substantially at the focus of the said quadric in order to provide the main beam illumination by the reflection on the said quadric of the light beams emitted by the said filament, and passage through an optical glass placed in front of the said quadric. The reflector according to the invention is characterised in that at least the lower segmenting plane of the reflector 1 is provided, on its inner surface illuminated by the main beam filament 4 of the light generation lamp, with a plurality of reflecting spherical elements 7, spaced apart in a concentric arrangement comparable to the Fresnel patterns with respect to their common axis passing through the focus F of the working reflecting conic section of the reflector, this focus F also being their common centre. Application to the motor industry. <IMAGE>
