ABSTRACT:
The invention relates to a masked beam motor vehicle headlamp of the type comprising, in succession: a reflector (1); a light source (3); a masking screen (E) having a cutoff edge (A); and a converging lens (4). The headlamp is characterized in that the screen is fitted, beneath its cutoff edge (A) and at least in its central portion, with an opening suitable for allowing a portion of the light flux directed towards the screen to pass therethrough. Means are provided to direct said light flux passing through said opening so that it is combined with the light flux which is not intercepted by the screen, thereby improving the light characteristics of the masked beam as finally projected by the headlamp.
