The present invention relates to a lighting device in a motor vehicle. The lighting device includes a light source for emitting light and at least one plate-shaped light conductor, which is made in form of a block optics. The block optics includes two boundary surfaces which run opposite towards each other at a certain distance, a totally reflective side surface between the boundary surfaces, and a light coupling-out area arranged between the boundary surfaces. A coupling-in section is arranged on at least one of the boundary surfaces. The lighting device further includes at least one substantially rod-shaped light conductor with a light output area which extends along the longitudinal extension of the light conductor in addition to the at least one block optics.

Lighting device in a motor vehicle having a plate-shaped light conductor and a rod-shaped light conductor

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 ().

Illumination device

A lamp for vehicles, in particular motor vehicles, has a light source and at least one light-guide arrangement associated with the light source for guiding the light radiated by the light source and coupled into the light-guide arrangement in a specified direction toward an outcoupling point. The lamp further has a light-diverting device in the light-guide arrangement for diverting and/or splitting the light. The light-diverting device is formed as a recess in the light-guide arrangement, and the diversion takes place by means of reflecting the light on one of the lateral surfaces of the recess. The recess is closed by means of a cover element, such that the recess is covered as viewed from the outside of the light-guide arrangement.

Lamp for vehicles

A motor vehicle headlight assembly includes a reflector extending along a focal line and having an open end, a light source including an elongated gas discharge tube extending within the reflector along the focal line for the light issued thereby onto the reflector to be reflected by the latter into the open end, and an at least translucent light-guiding plate spanning the open end of the reflector and operative for directing light passing through it onto an illumination area situated at a predetermined distance in front of the motor vehicle on which the headlight assembly is mounted when in use. The reflector has at least in general the configuration of a flattened cross-sectionally parabolic cylinder and consists at least in part of two opposing regions at least one of which is inclined by a predetermined angle about the focal line with respect to the position it would have assumed in a true cross-sectionally parabolic cylinder.

Headlight assembly with angularly displaced reflector regions

A headlight for a vehicle has a reflector, a light source, a lens through which a light reflected by the reflector passes, and at least one element which surrounds the lens at least over a part of its periphery and is at least partially light permeable so that the light emitted by the light source and not engaged by the reflector passes through the element and is collected, the element being provided with ring-shaped optical profiles which form a Fresnel lens.

Headlight for a vehicle

A motor vehicle light, comprising a concavely curved reflector; a light source inserted in the reflector; a cover element arranged after the light source as considered in a light outlet direction, by which the light source is at least partially covered when seen from outside on the motor vehicle light; a light-permeable disk for covering the motor vehicle light in the light outlet direction and which is free from optical profiles, the reflector being shaped so that a light emitted by the light source is reflected by the reflector so that it passes on the cover element at least substantially unaffected.

Motor vehicle light

A headlight for a vehicle operating in accordance with a projection principle has a reflector, a light source, a lens through which a light emitted by the light source and reflected by the reflector passes, at least partially light-permeable element which at least partially surrounds the lens at least over a part of its periphery and is provided locally with optical profiles so that the light emitted by the light source and not engaged by the reflector passes through the element and is collected by the element, the light reflected by the reflector and passing through the lens forming an upper bright-dark limit, and at least one additional light source which produces a limiting light and is arranged so that the light emitted by the at least additional light source at least partially passes through the element.

Headlight for vehicle in accordance with projection principle

A headlight for a vehicle operating in accordance with the projection principle, the headlight has a reflector, a light source, a lens through which a light reflected by the reflector passes, at least one partially light-permeable element which surrounds the lens at least over a part of its periphery, so that light which is emitted by the light source and not engaged by the reflector passes through and is collected by the at least one element, wherein, the reflector and the lens being formed so that light which is reflected by the reflector and passes through the lens forms an upper bright-dark limit, the element being formed at least locally as a fresnel lens with ring-shaped optical profiles, and further optical profiles arranged at least in a part of a beam path of the light passing through the element and deviating the light so that it illuminates a region in front of the vehicle above the bright-dark limit formed by the light reflected by the reflector and passing through the lens.

An illumination device for a vehicle has a light source, a reflector which reflects a light emitted by the light source so that the reflected light exits the illumination device in a first light outlet direction, the reflector being interrupted at least in one region, and at least partial light-permeable element arranged in the region and formed so that the light emitted by the light source passes through the light-permeable element and exits the illumination device in a second light outlet direction which deviates from the first light outlet direction.

Illumination device for vehicle

A brake light device for a motor vehicle comprises at least one brake light formed in accordance with prescribed regulations and having a light source, at least one auxiliary brake light and at least one light conductor connecting the auxiliary brake light with the prescribed brake light so that light from the light source of the prescribed light is supplied to the auxiliary brake light.

Brake light device for motor vehicle

A motor vehicle light, especially a signal light comprises a light source, a reflector, a closure disc for closing the motor vehicle light from outside, a collective lens device arranged between the reflector and the closure disc, a screen device arranged between the collective lens device and the closure disc and having light impermeable regions and light permeable regions. The collective lens device directs light which is reflected from the reflector to the light permeable regions. The screen device is formed reflective at its side facing the closure disc, the screen device at least at its side facing the closure disc being curved concavely.

Light for motor vehicle

In a headlight of a motor vehicle, having a housing and a diffusing lens enclosing with the housing an interior of the headlight, the interior is vented by means of a conduit exposed to air streams caused by travelling of the motor vehicle. The conduit is formed as an integrated part of the diffusing lens made of plastics.
