Abstract
In order to provide a device for generating an image on an image surface with N×M image elements which can be illuminated individually, comprising a plurality of semiconductor radiation sources, each of which generates radiation with at least one color, an optical imaging means with a beam guidance, by means of which a plurality of image elements can be illuminated with each of the semiconductor radiation sources, with which it is possible to generate an image on an image surface in as simple a manner as possible using radiation sources, it is suggested that the image surface ( ) be divided into a plurality of continuous image surface sections ( ), each comprising a two-dimensional ensemble of image elements ( ), that an illumination unit ( ) be associated with each of the image surface sections ( ) and that each illumination unit ( ) have at least one semiconductor radiation source ( ) and at least one optical imaging means ( ) of its own associated with this illumination unit ( ), this optical imaging means imaging a radiation outlet ( ) onto the corresponding image surface section ( ) in a free beam propagation.
