ABSTRACT:
The lighting device for a vehicle has at least one central reflector (10), which is formed as a substantially closed hollow body. The reflector (10) is formed from two reflector parts (11, 12), which have light outlet openings facing each other. The reflector parts (11, 12) are shaped like portions of an ellipsoid of revolution and are arranged so that their first focal points (Fl) coincide and their second focal points (F2) lie on the peak of the opposing reflector part (11, 12). The light emitting body (16) of the light source is arranged in the vicinity of the first focal points (F1). Because of this structure of the reflector (10) almost all of the light issuing from the light emitting body (16) is concentrated on the second focal points (F2) of the reflector parts. A light guide (18) is positioned to guide light away from each reflector part in the vicinity of its second focal point (F2). The light guide (18) conducts the light entering its end portion connected to the reflector (10) to a vehicle light outlet unit (19). The vehicle light outlet units (19) can have their own reflector (21) for collection and formation of the light beam from the light issuing from the light guide (18).
