Abstract:
1. An optical module for a motor vehicle lighting device, capable of emitting at least one type of light beam having a cut-off and comprising: a light source disposed in a reflector; a dioptric element disposed in front of said reflector; a shield disposed between said light source and said dioptric element and having at least one optically active position where it intercepts some of the light rays emitted by said light source, said shield comprising an optically active edge suitable for forming a cut-off in a light beam emitted by the optical module, wherein an additional optical element is disposed between said light source and said shield, said additional optical element being in the vicinity of said optically active edge of the shield and having at least one reflective surface capable of redirecting, above the optically active edge of the shield, at least some of light rays that normally would have been blocked by the shield are reflected by the additional optical element above said optically active edge of the shield toward said dioptric element instead of contacting the shield when said light rays are emitted by the light source toward said shield.
