Abstract:
1. A dimming device for a searchlight for adjusting a brightness of a light field generated by the searchlight said dimming device comprising a plurality of different screening elements which are formed and provided to partly or completely screen a light emitted by the searchlight, wherein the screening elements are formed by different structured masks at least partly screening the light emitted by the searchlight and which include regularly arranged opaque or partly transparent regions and transparent regions, and means provided for incremental adjustment of the brightness of the generated light field of the searchlight either to bring the screening elements into a region of the light emitted by the searchlight in order to reduce the brightness of the light field generated by one brightness level, or to remove the same from the region of the light emitted by the searchlight in order to increase the brightness of the light field generated by one brightness level.
