Abstract: 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.

Abstract: 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.
