发明名称 Headlamp for Vehicles
摘要 A headlamp for vehicles with a semiconductor-based light source arrangement including a number of chips with a matrix-type arrangement of the light sources for the forming of a light source group. Neighboring light sources have an equidistant distance relative to one another. The headlamp also includes an optics unit for the projection of the light sources to form a given light distribution. At least two light source groups are arranged on a common carrier, and a group distance between neighboring light source groups is larger than the distance between the neighboring light sources of the respective light source groups. The light source groups are assigned a common optics unit, and the optics unit being configured so that border light sources of neighboring light sources groups arranged on edges of the respective neighboring light source groups and facing one another are projected to form overlapping light spots. The border light sources are dimmed down so that the overlapping light spots have an illuminance lying within a desired value deviation of the illuminance of the neighboring light spots. The neighboring light spots being projected by depiction of the light sources are situated next to the border light sources of the respective light source groups.

主权项 1. A headlamp for vehicles comprising: a semiconductor-based light source arrangement, including: a number of chips with a matrix-type arrangement of the light sources for the forming of a light source group, wherein neighboring light sources have an equidistant distance relative to one another, and an optics unit for the projection of the light sources to form a given light distribution, wherein at least two light source groups are arranged on a common carrier, wherein a group distance between neighboring light source groups is larger than the distance between the neighboring light sources of the respective light source groups, wherein the light source groups are assigned a common optics unit, wherein the optics unit being configured so that: border light sources of neighboring light sources groups arranged on edges of the respective neighboring light source groups and facing one another are projected to form overlap-ping light spots, and the border light sources are dimmed down so that the over-lapping light spots have an illuminance lying within a desired value deviation of the illuminance of the neigh-boring light spots, the neighboring light spots being projected by depiction of the light sources being situated next to the border light sources of the respective light source groups.
