Abstract

A lighting device is provided for a motor vehicle. The lighting device comprises at least one imaging component with at least one active surface, on which imaging elements for the generation of pixels of a light distribution are arranged matrix-like. The lighting device further comprises a light-guiding optics having at least one entry surface and one exit surface. During operation of the lighting device, the light emanating from the at least one active surface enters the light-guiding optics through the at least one entry surface and exits the light-guiding optics through the exit surface. The exit surface has a different shape and/or a different size than the at least one active surface, and/or a plurality of active surfaces and only one exit surface or a plurality of adjacent exit surfaces are provided.
