A headlamp for an automobile, incorporating a light source provided with a substantially cylindrical filament f, an elliptical reflector C having two foci F1, F2, one of which is located in the proximity of the filament f and the other in front of this filament, and a converging lens L the focus of which is in the proximity of the front focus of the reflector C. The reflecting surface of the reflector is modified in a critical zone Z of the reflector, this critical zone Z being defined as that capable of projecting on a standard screen, images of the filament forming a predetermined angle a at most equal to 30 DEG with the vertical. <IMAGE> |
