Patent number: 11365859Abstract: The invention relates to a motor vehicle headlight (1) comprising a light module having a plurality of light sources (110, 120, 130) and a plurality of primary optics (210, 220, 230), wherein the light sources (110, 120, 130) each have a light-emitting surface (111, 121, 131) and are arranged on a common circuit board (50). The circuit board (50) has a circuit board reference point and a light reference plane, wherein the light reference plane is defined by at least three light reference points, and the circuit board reference point lies in the light reference plane. The primary optics (210, 220, 230) each have a light-incoupling surface (211, 221, 231) and a light-outcoupling surface (212, 222, 232), and are held in position by a common holder (60). The holder (60) has a holder reference point and an optics reference plane, which is defined by at least three optics reference points (21, 22, 23) and in which the holder reference point also lies.Type: GrantFiled: December 3, 2018Date of Patent: June 21, 2022Assignee: ZKW Group GmbHInventors: Andreas Hölzl, Sascha David, Matthias Frühwirth, Josef Gürtl
