The light device comprises a housing () covered with a transparent or semi-transparent cover () that delimit an inner chamber () inside the housing (), a light unit () situated in the chamber () and equipped with at least one light source, a cooler () associated with the light unit (), and a tubular cooling conduit () that passes through an opening () in the housing () into the chamber () to supply cooling medium () from the cooling medium () source installed outside the housing () to the cooler () and comprises a drive means () for forced flow of the cooling medium () in the tubular cooling conduit (). The tubular cooling conduit () is connected to the cooler () in such a way that the cooling medium () does not escape from the tubular cooling conduit () and cooler () to the surrounding space in the chamber (). Inside the tubular cooling conduit (), one or more adjacent supply channels () are provided to supply the cooling medium () to the cooler () in one direction, and next to the supply channel () or channels (), one or more exhaust channels () are provided to simultaneously discharge the cooling medium from the cooler () in the opposite direction out of the housing ().

Light device for a motor vehicle

A light device, especially a headlight for motor vehicles, comprises a holding bushing (), covered by a translucent cover (), and an inner chamber () having mounted there in an optical system () for generation of light rays and enabling of controlled selective changes of a light trace on a projection surface. The optical system includes a lens () and a light assembly () comprising at least one light source and a carrier to carry the light source. The lens is arranged in a fixed position with respect to the position of the translucent cover, and the position of the light assembly is selectively adjustable in a controlled way with respect to the position of the lens by movement of the light assembly in direction (A) and/or by movement in direction (B), wherein the directions (A) and (B) are substantially perpendicular to direction of optical axis (C) of the lens.

Light device, especially a headlight for motor vehicles

A light device, especially a headlight of motor vehicles, comprises at least one light unit (), or a group () of light units, at least one optical directing element (), adapted to direct the light beam emitted by the light unit, or group of light units, to the required direction, and at least one output lens () for passage of at least a part of the light rays of the light beam or beams to create a light pattern (A, B, C) on the display surface (ZY). On the route of the light beam between the optical directing element and the output lens, there is at least one optical diaphragm element () containing a system of trim edges () to create the required shape of the cross-section of a part or parts of the light beam designed for transmission along the above-mentioned route.

A headlight, especially a motor vehicle headlight, comprises a bushing () with a translucent cover () forming an inner chamber () including a light source (), an optical system () for guiding the light beam from the light source, a cooling body having the light source mounted thereon and fitted with cooling elements () to extract heat from the heat source, and a cooling channel () 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.
