摘要： In a vehicle headlight comprising a light module (1) with a light source support (3), with at least one light source (17) and a reflector part (5) associated with the at least one light source (17), it being possible for reference elements (24) on the reflector part (5) to be brought into an operative connection with corresponding reference elements (25) on the light source support (3), the light source support (3) can be pushed into a guide part (2) with guide rails (6) for the reflector part (5), and the reflector part (5) has a catch (22) associated with the light source support (3) to displace the reflector part (5) together with the light source support (3) along the guide rails (6), which are designed to bring the reference elements (24) on the reflector part (5) into an operative connection with the corresponding reference elements (25) on the light source support (3) when the light source support (3) is pushed in.

摘要： The invention relates to a headlight (1), comprising a headlight housing (10) with a light exit opening (12), which is closed by means of a cover plate (11), at least one LED light source (21), which is arranged in at least one light module (20) positioned in the headlight housing (10) for generating a specified light distribution in front of the headlight (1), as well as a condensation protection device (30) with at least one air duct (40) for guiding air (41), as well as with at least one radiation emitter (60), wherein the at least one air duct (40) has an air entry opening (42) and at least one air exit opening (43), and the air exit opening (43) preferably faces the cover plate (11), as well as the air (41) guided in the air duct (40) can be heated up by means of the thermal radiation generated by the radiation emitter (60). The at least one radiation emitter (60) is arranged within the air duct (40) in the region of the air entry opening (42), wherein the air duct (40) is made of an infrared radiation-reflecting as well as light-impermeable wall material (45), and the air duct (40) has at least one curved longitudinal axial section (50) with a radius of curvature (51) and an angle of curvature (52) between the air entry opening (42) and the air exit opening (43).
