Abstract (en)

[origin: CN108662548A] The invention relates to a vehicle headlight (100), comprising a headlight housing (101), at least one light source (102), at least one projection optical system (104), at least one cooling channel (107) and a cooling medium. The at least one light source (102) is set up to emit light in the form of a light beam (105) in the direction of the at least one projection optics (104) and to form a lightimage on the road in front of the vehicle. The at least one light source (102) and the at least one projection optics (104) are located within the headlight housing (101). The at least one cooling channel (107) is thermally conductively connected to at least one heat source and the at least one cooling channel (107) is arranged to cool the heat source when the cooling medium flows through it. Theat least one cooling passage (107) comprises at least one releasable connection coupling (108, 109) which is inserted into the cooling passage (107).
