Abstract: A method for operating an illumination device as a day travelling light, in particular for automotive vehicles, wherein the device comprises a light source in an illumination housing and a means associated with the light source for bundling the light emitted by the light source, utilizes a light source comprising at least one LED (13).

Abstract: Headlight for motor vehicles, comprising at least one light source and at least one light guide associated with each light source, into which the light emitted by the light source can be coupled via a light coupling surface, wherein each light guide is associated with a light terminator body into which the light from the light guide is passed, wherein the light terminator body has a light output surface and the output light can be imaged through a downstream lens, wherein the at least one light terminator body is fixed on or to a holder and the holder can be pivoted about at least one axis and/or be displaced in at least one plane relative to the at least one lens.

Abstract: The headlight, especially for a motor vehicle, includes at least two separately adjustable reflectors and a reflector height adjusting mechanism for adjusting the reflector heights separately or synchronously. The reflectors include a first reflector for high beam light and/or fog light and a second reflector associated with a low beam light module. The reflector height adjusting device includes separate adjusting devices for individually adjusting the respective heights for the at least two separately adjustable reflectors and a coupling member for the separate adjusting devices. When the separate adjusting devices are put in a coupled state by the coupling member the heights of the at least two reflectors are synchronously adjusted by operation of only one of the separate adjusting devices. The method for adjusting light radiated from the headlight includes performing a pre-adjustment in which each of the reflectors is separately adjusted by the separate adjusting devices.

Abstract: A headlight for a motor vehicle has a light module with at least one reflector and a light source, a first frame with which at least a part of the light module is connected, a first adjusting element for swivelling the first frame around a first swivel axis, a second frame in which the first frame is supported and which is turnable around a second swivel axis, a second adjusting element for swivelling the second swivel frame, a body-fixed frame support in which the second frame is supported, the frames being arranged so that the swivel axes extend perpendicular to one another and arranged in one plane, a base adjustment element for adjusting at least one of the frames around an adjusting axis which is aligned with one of the swivel axis.

Abstract: A device for adjusting a light emission direction of a motor vehicle headlight has a unit for executing a pivoting movement of at least one part of the motor vehicle headlight that is held by a suspension and which effects the light emission direction, about an axis of rotation that is approximately parallel to a vertical axis of the motor vehicle, the unit for executing the pivotal movement having at least one electric motor selected from the group consisting of a direct current motor and an alternating current motor.

Abstract: A headlight for a motor vehicle, having a light module, at least one reflector, the module having at least one holding frame which is turnable about two axes extending substantially perpendicularly to one another in a plan parallel to a light outlet plan of the light module, the axis intersecting one another and having an intersecting point located inside the light module.

Abstract: The invention concerns a motor vehicle headlight with an ignition device (3) for generating an ignition voltage for operating a light (4). The headlight has a safety device 1 for protection from injuries caused by electricity, wherein the ignition device (3) comprises a housing (5) for receiving the light (4) and an ignition switch which can be connected to the light (4) and terminals (6, 7) for electric connection of the ignition switch and the vehicle electrical system. The housing (5) can be mounted to a base plate (2). To improve safety of maintenance or mounting of the headlight, in particular to prevent injuries through contact with exposed electrically conducting parts where high voltages could be present, the use of a safety device 1 is proposed which is disposed on the base plate 2 and comprises means for mounting the housing 5, wherein the ignition device 3 can be connected to the vehicle electrical system via the safety device 1 only when the housing 5 is mounted.
