Abstract

The light (l) includes an especially compact lamp (2) and a main reflector (5) which is preferably arranged for the emission of a narrow light beam. An additional reflector (31) is arranged in at least a part of the side extent of the main reflector. The main reflector consists of transparent material and is coated with a reflection layer (23) at its outer or inner side. The additional reflector is arranged at the outer side of the main reflector and no reflection layer is provided on the main reflector in the area of the additional reflector.
