Abstract:
1. A lighting device, comprising: a plurality of semiconductor light sources; and a plurality of optical waveguides; wherein the optical waveguides each have at least one light coupling-in surface and a light coupling-out surface; wherein the light coupling-in surfaces of the optical waveguides are respectively assigned a light-emitting surface of at least one semiconductor light source, such that light emitted by the light-emitting surface of the at least one semiconductor light source impinges on the light coupling-in surface of the optical waveguide assigned thereto; wherein the light coupling-out surfaces of the optical waveguides are arranged in the form of a matrix; wherein the light coupling-in surface of the respective optical waveguide is smaller than the light-emitting surface of the at least one semiconductor light source assigned to said optical waveguide, and an optical diaphragm embodied as a grating having grating cells is provided, which is arranged in the region of the light coupling-in surfaces of the optical waveguides, such that light coupling-in surfaces belonging to different optical waveguides are arranged in different grating cells of the optical diaphragm embodied as a grating.
