Lighting module for a vehicle headlight
First Claim
1. A lighting module for a vehicle headlight for producing a light beam of the cut-off type, the module including:
- a first reflector having a substantially elliptical surface for reflecting light rays, at least one light source arranged in the vicinity of the first focus of the said first reflector, a second reflector for producing the cut-off output beam, the focus of the said second reflector being located in the vicinity of the second focus of the said first reflector, and a third reflector which is a so-called bender, the upper face of which is reflective, the said bender being located between the said first reflector and the said second reflector and having an edge which is a so-called cut-off edge, and which is arranged in the vicinity of the second focus of the said first reflector, whereby to form the cut-off in the light beam, the light source being a light emitting diode.

Abstract
The present invention is concerned with a lighting module for a vehicle headlight for giving a light beam of the cut-off type, particularly one which is adapted to use with light-emitting diodes. The module has a second reflector having a substantially elliptical surface for reflecting light rays and at least one light source arranged close to the first focus of the first reflector. The module also includes a second reflector for producing the cut-off or dipped output beam, the focus of this reflector being arranged close to the second focus of the first reflector. The module further includes a third reflector or bender, having a reflective top face and being situated between the first and second reflectors. This third reflector has a cut-off edge arranged close to the second focus of the first reflector, whereby to form the cut-off within the light beam. The light source is a light-emitting diode.
