Abstract (en)

[origin: DE19814300A1] The invention relates to a headlight or a light (1) for a vehicle, comprising a diffusing panel (2), a casing (5), light sources (3) mounted in the housing (5), reflectors (4) allocated to said light sources and a ventilation system comprising at least one air intake opening (10), an air outlet opening (15) and a blower (7). In order to avoid diminished headlight efficiency in a headlight with fogging plastic parts, the invention provides a blower (7) that is a suction blower suctioning the air from the casing (5). Air guiding devices (30, 31) are mounted inside the casing (5) in such a way that the blower (7) guides the air away from the diffusing panel (2) and directs it pass the hot air pockets towards the back part of the casing opposite to the diffusing panel (2).
