摘要

The lamp (1) has a lamp unit (3) e.g. LED, arranged on a base carrier (2), and an external cover (5) formed as a component of a housing, which is arranged in a pre-determined distance before the lamp unit. A primary optics (6) with a catadioptric imaging device is attached to the lamp unit located on the base carrier. The imaging device forms a parallel beam of rays (10) from a light emitted from the lamp unit, where the imaging device comprises a converging lens (8) and a reflection device (9).
