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.

Light source

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.
