Claim 0:
1. 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);
a condensation protection device (30) arranged in the headlight housing (10) with at least one air duct (40) for guiding air (41); and
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 at least one air exit opening (43) faces the cover plate (11), wherein the air (41) guided in the at least one air duct (40) can be heated by thermal radiation generated by the at least one radiation emitter (60),
wherein the at least one radiation emitter (60) is arranged within the at least one air duct (40) in the region of the air entry opening (42), wherein the air duct (40) is made of an infrared radiation-reflecting and light-impermeable wall material (45), and the at least one 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 at least one air exit opening (43), and
wherein the at least one air duct (40) between the air entry opening (42) and the at least one air exit opening (43) has a first curved longitudinal axial section (50) as well as, spaced apart therefrom in the longitudinal axial direction (44) of the air duct (40), at least one further, second curved longitudinal axial section (55).
