ABSTRACT:
The invention relates to a headlamp for an automobile vehicle comprising an elliptical reflector, a light source positioned in a region of the first focus of the reflector, a lens, the focus of which is in a region of the second focus of the reflector, and a mask interposed between the reflector and the lens to effect a cut-off of the light beam emitted. A mirror is located in front of the mask and adapted to return direct light rays emitted by the light source onto the front face of the mask which thereby diffuses them towards the lens.
