A communication device is provided for a motor vehicle that works with traffic-relevant information provided through light signals. The communication device comprises a primary imaging optical system to create the input image from the received scenic image, which may comprise a light car2car signal and/or a light car2X signal including traffic-relevant information. It further comprises a DMD array of mirrors for receiving the input image and transmitting it to a primary optical sensor adapted to convert the input optical image to an electric signal for processing, to thereby find out whether and what places of the input image sources of the signals are found in.

Communication device of a motor vehicle

A light source comprises light emitting diodes (LED) () with a monocrystal (), covered by a cap () of a transparent material at one side and fitted with an anode contact element () to supply and a cathode contact element () to lead away direct current at the other side. The LED's arranged in a row are connected with their anode contact elements to one thermally and electrically conductive cooling plate () and with their cathode contact elements () to another cooling plate (). These mutually insulated cooling plates are arranged with their lateral sides next to each other and on the surfaces averted from the LED's they are fitted with cooling elements for transfer of heat to cooling media. The cooling elements may comprise sets of cooling fins () arranged on the sides of the cooling plates averted from the LED's.

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.
