Abstract

A lighting device for a vehicle, having a plurality of light sources, which are arranged in an array, in particular in line-by-line and column-by-column fashion, and can be operated independently of each other at least in part, wherein the light sources emit light during operation; an exit face through which the light emanating from the light sources passes; and a plurality of extensive boundary elements, which extend at least partly in a region between the light sources and the exit face and serve to separate the light emanating from different light sources, wherein at least some, preferably all, of the extensive boundary elements have a reflector which at least partly reflects the light emanating from one of the light sources in the direction of the exit face.
