ABSTRACT:
A dimmed headlight for a motor vehicle has a vertical center section defining an ellipse whose outer portion transits into an apex portion. The apex portion defines an inner focal point and an outer focal point and the upper elliptical portion defines a focal point coinciding with said inner focal point and a plurality of outer focal points located on the long axis of the ellipse behind the outer focal point of the apex portion when viewed in the direct of reflected light rays. An objective is arranged before the last one of the outer focal points to collect the reflected light rays. The lower part of the reflector contains a light reflecting member and a diaphragm extending transversely to the long axis in the outer focal point of the apex portion. The light reflecting member is oriented such as to reflect downwardly directed light rays from the light source against an upper part of the apex portion. In this manner, light intensity of reflected beam is increased and an improved illumination of the driveway before the vehicle is obtained.
