Abstract: A light device, especially a headlight for motor vehicles, comprises a holding bushing (1), covered by a translucent cover (2), and an inner chamber (3) having mounted there in an optical system (5) 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 (51) and a light assembly (52) 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.

Abstract: A light device, especially a headlight of motor vehicles, comprises at least one light unit (1), or a group (1a, 1b) of light units, at least one optical directing element (3, 2e, 3f), 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 (4) 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 (11, 21, 31) containing a system of trim edges (13, 23, 33) 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.

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.

Abstract: A light source comprises light emitting diodes (LED) (1) with a monocrystal (2), covered by a cap (3) of a transparent material at one side and fitted with an anode contact element (4) to supply and a cathode contact element (5) 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 (43, 45) and with their cathode contact elements (5) to another cooling plate (53, 55). 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 (44, 54; 46, 56) arranged on the sides of the cooling plates averted from the LED's.

Abstract: A source line simulator system determines a line of source code that corresponds to a virtual return address in response to executing a debugging command on the source code. The simulator system determines whether the line of source code that corresponds to the virtual return address is correct and can enable a simulator mode based on a determination that the line of source code that corresponds to the virtual return address is not correct. The simulator system can generate a debugging graphical user interface (GUI) that displays an indicator at a line of source code that is correct.

Abstract: A signal lamp for a front and rear lighting of a vehicle includes at least one light source for emitting light, wherein the at least one light source is hidden from view; a reflector for reflecting the light emitted by the at least one light source away from the vehicle; and at least one light guide disposed between the reflector and a cover of the signal lamp, the at least one light guide having a first end and a second end, wherein the first end is disposed adjacent the at least one light source and the second end is located adjacent a focus point of the reflector.
