ABSTRACT:
A dimming device for a searchlight for adjusting the brightness of a light field generated by a searchlight is provided. The dimming device comprising a plurality of different screening elements, which are formed and provided to partly or completely screen the light emitted by the searchlight. The screening elements are formed by different structured masks at least partly screening the light emitted by the searchlight, which include regularly arranged opaque or partly transparent regions and transparent regions. Means each are provided for incremental adjustment of the brightness of the generated light field of the searchlight either to bring the screening elements into the 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.
