A low beam headlamp for motor vehicles includes an objective made of pressed glass whose one side is formed as aspheric partial surfaces of identical or different aspherity. The partial surfaces are staggered in the direction parallel to the optical axis of the objective and the resulting step has rounded edges. The aspheric partial surfaces adjust light distribution to achieve a desired quality of the light-dark boundary zone projected on the driveway, and provide corrected color fringes of the passing light beam.

Low beam or fog headlamp for motor vehicles

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.

Dimmed headlight, particularly for motor vehicles

A headlight arrangement for vehicles, particularly for power vehicles, comprises a light source with a light reflector forming a light beam which illuminates a roadway with a predetermined light distribution, and at least one adjustable element for changing the light distribution.

Headlight arrangement for vehicles

In the headlight of a motor vehicle, a holder of the objective is secured against rotation but is axially displaceable in the housing of the headlight. In order to adjust a width of cut of the objective a rotatable spacer ring, provided with projections cooperating with respective projections of the housing, is positioned between the holder and the end wall of the housing so as to adjust the position of the objective on an optical axis of the headlight.
