Abstract
The invention relates to an apparatus for generating light, comprising a plurality of light sources (), —a control device (), which drives the light sources (), and a superimposition optical unit, which superimposes the light emitted by the light sources () in an exit opening (). It is an object of the invention to provide an apparatus which is improved compared with the prior art. For this purpose, the invention proposes that the superimposition optical unit comprises a first concave mirror (), in the focal plane of which the light sources () are situated, an optical grating (), onto which the first concave mirror () reflects the light () emitted by the light sources (), and —a second concave mirror (), which reflects the light () diffracted at the optical grating () onto the exit opening () situated at the focus of the second concave mirror ().
