Abstract
A headlight, especially a motor vehicle headlight, comprises a bushing (1) with a translucent cover (2) forming an inner chamber (3) including a light source (4), an optical system (5) for guiding the light beam from the light source, a cooling body having the light source mounted thereon and fitted with cooling elements (61) to extract heat from the heat source, and a cooling channel (7) for passage of the cooling media for heat extraction from the cooling elements. The cooling channel is closed with respect to the chamber to prevent the cooling media from passing through the chamber outside the cooling channel The body forms the wall of a part of the cooling channel, and the cooling elements face the inner space of the cooling channel. The part of the cooling channel whose wall comprises the cooling body is arranged in a controlled movable way in the inner chamber.
