Abstract: A semiconductor light module with at least one semiconductor light source and with a cooling body. The cooling body has a base section with a mounting side on which is mounted the semiconductor light source. The base section has a cooling side on which is arranged a cooling structure. A blowing unit is provided, which produces a forced convection of the cooling structure with blown air stream. An inventive deflection channel is provided and it is designed in such a manner that a deflection of the blown air stream by at least 90° between the air outlet direction of the blown air stream from the blowing unit and a flow direction of the blown air stream through the cooling structure are produced.

Abstract: An illumination device comprising a housing positionable at a distance from an area to be illuminated and having at least one lighting module, on a support in the housing, that has lighting units having the same light distribution characteristics. Each of the lighting units contains lighting elements and associated lenses arranged in front of the same in the light-emitting direction. Different lighting modules may include lighting units having different light distribution characteristics, while the lighting units have optical axes running parallel to each other. At least one lighting unit is configured such that its light distribution characteristics have at least one asymmetrical section relative to a central plane of the lighting unit.

Abstract: A ship includes a network, integrating services for security and control services and/or for multimedia and infotainment services on board the ship. The service-integrating network includes services for security-related systems as well as services for non-security-related systems. The conventional situation for network solutions on board cruise ships is characterized by a number of service functions and individual networks distributed over the entire ship. In at least one embodiment, the service-integrating network is embodied as a redundant ring both for services for security-relevant systems as well as for services for non-security-related systems. As such, the number of security functions and service functions and the number of individual networks can be advantageously reduced to a common high-security network.

Abstract: The invention relates to a headlight for a motor vehicle with a sealing disk, which as a component of a housing seals an interior enclosed by the housing from the environment, wherein a layer system, comprising a lower layer, followed by a metal layer and an upper layer, is deposited on the side of the sealing disk directed towards the interior by means of a vacuum method, wherein the lower layer and/or the upper layer is deposited either as a nitride of the elements Al or Si or as an oxide or a mixed oxide of the elements Si, Ti Al, Zn, Sn, In, Nb, Zr, or Ta.

Abstract: A method for welding the surfaces of materials, of which at least one is glass, during which the energy that is required for the welding process is provided by with a laser beam, characterized by the fact that an intermediate sealing glass is applied between the surfaces that are to be welded and that the laser beam is adjusted in such a way that only the intermediate sealing glass melts.

Abstract: The interferometer comprises a light source, at least one beam splitting means, a beam combiner means, measuring and reference arms as well as wave guides for guiding the light to the beam splitting means and for guiding the light back to photodetectors. Beam splitting means and beam combiner means are formed by integrated optics elements on a substrate. The wave guides on the substrate form a measuring arm (7.sub.1) and two reference arms (6.sub.1, 8.sub.1) which have different optical path lengths for setting a phase difference. An evaluation electronics for determining correct as to signs, the change in optical path length in the measuring arm (7.sub.1) is connected to the photodetectors.
