Headlight for a motor vehicle comprising a reflector and an optical deviation element
First Claim
1. A headlight for a motor vehicle comprising:
- a reflector having a wall, an optical axis and at least one focus;
a light source disposed near said at least one focus, anda transparent optical deviation element disposed in front of a portion of the reflector, for providing a substantially horizontal spread of light, wherein the reflector includes at least one arcuate portion on at least one side of a plane passing through the optical axis of the reflector, at least one additional reflector being disposed adjacent to and on a side of the at least one arcuate portion opposite the optical axis, for collecting at least part of the light from the source passing through the at least one arcuate portion so as to produce at least one light beam is not intercepted by the transparent optical deviation element.

Abstract
Headlight for a motor vehicle comprising a reflector with an optical axis and at least one focus, a light source placed close to a focus of the reflector, and a transparent optical deviation element placed in front of part of the reflector, this element consisting of a module comprising a so-called “square lens” and the reflector placed behind the said lens, the module being able to provide an essentially horizontal spread of the light. The wall of the reflector comprises at least one scallop on one side of a plane passing through the optical axis of the reflector, and at least one additional reflector is disposed on the side of the scallop opposite to the optical axis, this additional reflector being designed to collect at least some of the light coming from the source emerging from the scallop, and to produce an additional beam which is not intercepted by the lens.
