HEADLIGHT
First Claim
1. A headlight, especially a motor vehicle headlight, comprising a bushing (1) with a translucent cover (2) forming the inner chamber (3), inside the chamber (3) a light source (4), an optical system (5) for guiding the light beam from the light source (4), a cooling body (6), the light source (4) being mounted on the side of the cooling body (6) that faces the inner chamber (3), the cooling body (6) being fitted with cooling elements (61) to extract heat from the heat source (4), and a cooling channel (7) for passage of the cooling media for heat extraction from the cooling elements (61), wherein the cooling channel (7) is closed with respect to the chamber (3) to prevent the cooling media from passing through the chamber (3) outside the cooling channel (7), the body (6) forms the wall of a part of the cooling channel (7), the cooling elements (61) of the cooling body (6) face the inner space of the cooling channel (7) and the said part of the cooling channel (7) whose wall comprises the cooling body (6) is arranged in a controlled movable way in the inner chamber (3).

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.
