Patent ID: 7347602

Claim:
Headlight for a motor vehicle having an optical axis, intended to produce a light beam with a cut-off in the top region of the beam, comprising: (a) a reflector, notably of the ellipsoidal type, having a first focus and a second focus disposed on the optical axis; (b) a light source placed substantially at the first focus of the reflector, (c) a convergent optical means having an object focus situated close to the second focus of the reflector; (d) a first shield having a substantially horizontal top edge situated in the vicinity of the second focus of the reflector, the top edge of the first shield being disposed adjacent to and extending substantially transversely to the optical axis of the headlight; and (e) a second shield having a substantially horizontal top edge substantially parallel to the top edge of the first shield but offset along the optical axis in order to be situated closer to the optical means, the top edge of the second shield being disposed adjacent to and extending substantially transversely to the optical axis of the headlight; wherein the first and second shields create a cut-off in the light beam of the headlight, notably limiting iridescence phenomena, and the second shield and the first shield comprise a single piece with a transverse section substantially in a V or U shape, the two arms of which correspond to the two shields.
