Lighting system and lamp-reflector unit

摘要

The invention relates to a lighting system (1) comprising a lamp-reflector unit (2) in a housing (5), the housing (5) having air flow cooling means (7) and a ventilation opening (8). The lamp-reflector unit (2) is provided with a shield (9), for example a black coating, for avoiding light originating from the lamp-reflector unit (2) to emit from the housing (5) through its ventilation opening (8) during operation of the lamp (16). Thus a simple and relatively quiet cooling of the lighting system (1) is obtained.
