VEHICLE HEADLIGHT WITH AERATION SYSTEM

The invention aims to optimize air circulation by conducting it as close as possible to the window (4) of the projector (10), while completely avoiding the risk of water entering the housing (5). To this end, the invention exploits the solution of an air inlet (A1) in the projector at the rear of the housing (5). According to one embodiment, a projector, intended to be inserted into a motor vehicle, comprises a housing (5) forming a housing for a light source (2), a window (4), a reflector (8, 8a, 8i) and a ventilation opening (6a) of a block (6) arranged in a wall of the housing (5). This projector comprises a duct (11) having an inlet (11 e) and an outlet (11 s), this duct being connected by its inlet (11 e) to the ventilation opening (6a), and its outlet (11 s) is placed as close as possible to the window (4). The air (A2) is thus diffused as close as possible to the level of the lower part of the window (4).
