Abstract

The device has a light source (2), a pot-shaped main reflector (6) for emitting an essentially narrow light beam and an additional reflector element (7) in front of a sub-region of the lateral periphery of the main reflector. The additional reflector is made of transparent material and structured so that it totally reflects at least part of the light from the source incident on it.
