A projector having a lamp and a reflector that reflects the light beams emitted by the lamp toward a light exit opening of the projector is provided. It is possible to vary the position of the reflector and of the lamp relative to one another, and to set the distribution of the exiting light by displacing the reflector and/or the lamp. The reflector is provided with facets that form a reflective surface for reflecting the light beams emitted by the lamp. The facets being constituted by their surface shaping such that the light beams generate a light field with a desired light distribution and whose light beam width can be set in a wide range by displacing the reflector and/or the lamp.

A lighting device comprising a plurality of lighting modules which include a module carrier on which a light source with a plurality of controllable light-emitting diodes emitting light of different wavelengths and arranged on a board, a temperature sensor and a module electronic are arranged. Said module electronic contains a digital circuit with a microcontroller for the local and autonomous signal processing, which actuates the LEDs in dependence on the temperature such that the brightness, color and chrominance of the light mixture composed of the LEDs emitting light of different wavelengths is constant. Said lighting modules being connected with other lighting modules or an external controller via a digital interface for transmitting the board temperature of the respective lighting module detected by means of the temperature sensor. A central master module or the external controller actuates the lighting modules such that a uniform brightness is obtained over the radiating surface.

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.

Disclosed is an illumination device comprising at least one electrical planar lamp module that is provided with a module housing, the depth of which is small compared to the light-emitting area of the planar lamp module. Said planar lamp module can be connected to other planar lamp modules. The module housing encompasses a lamp housing and a lamp frame which is connected to the lamp housing and is provided with means for mechanically connecting the lamp frame to the lamp frame of at least one additional planar lamp module.

A holder for a lamp with a glass vessel and a lamp base includes at least one spring element and at least one connecting part which can move relative to the spring element between two positions. In the first position the locking part thereby enters into contact with the spring element to that this is blocked and pressed against the lamp base of a lamp inserted in the bushing of the holder. In the second position the locking part exerts no or only reduced pressure on the spring element.
