Patent number: 11371669Abstract: The invention relates to a lighting device (1) for a motor vehicle headlight for generating a light pattern with a light-shadow line, wherein the lighting device comprises a light source (10), a light-permeable body (100), a light injection element (101) for injecting light which the at least one light source (10) emits, and a projection device (500). The light-permeable body (100) has an aperture device (103) with an aperture edge region (104). A light beam (S2) spreading in the optical element (110) is displayed by the projection device (500) as a light pattern (LV) with a light-shadow line (HD), with the light-shadow line (HD) being determined by the aperture edge region (104) of the aperture device (103).Type: GrantFiled: November 26, 2019Date of Patent: June 28, 2022Assignee: ZKW Group GmbHInventors: Matthias Kemetmüller, Bernd Eichinger, Markus Danner, Andreas Moser, Lukas Leonhartsberger
