Abstract

Bei einem Reflektor für abgeblendete oder abblendbare Kraftfahrzeugscheinwerfer, dessen Reflexionsfläche einen asymmetrischen Zwickelbereich (1), einen oberen Bereich (2) und einen unteren Bereich (3) aufweist und dessen Reflexionsfläche so ausgebildet ist, daß die gewünschte Lichtverteilung ohne korrigierende Lichtscheibe hergestellt ist, ist zur möglichst vollständigen Anpassung der Lichtverteilung im horizontalen und vertikalen Bereich senkrecht zur Mittelachse des Scheinwerfers an eine gewünschte Lichtverteilung der Flächenverlauf der Reflexionsfläche im asymmetrischen Zwickelbereich (1) derart gestaltet, daß jedes in einem beliebigen Punkt der Reflexionsfläche reflektierte Wendelbild mit ein und demselben Punkt in unmittelbarer Nähe der z. B. vom Gesetzgeber vorgegebenen Grenzlinie gelagert ist. With a reflector for dimmed or dimmable Motor vehicle headlights, the reflection surface one asymmetrical gusset area (1), an upper area (2) and has a lower region (3) and its reflection surface is designed so that the desired light distribution without corrective lens is made for complete adjustment of the light distribution in the horizontal and vertical area perpendicular to Center axis of the headlamp to a desired one Light distribution of the surface course of the reflection surface in the asymmetrical gusset area (1) designed so that each in reflected at any point on the reflective surface Spiral image with one and the same point in the immediate vicinity the z. B. stored by the legislator predetermined limit line is.
