Lighting device for a vehicle, comprising a lighting module having at least one light source and one luminous surface which is illuminated by the light source, from which light emanates during operation of the lighting device, as well as a liquid crystal display which is arranged at least partially in front of the luminous surface in such a way that, during operation of the lighting device, at least one portion of the light emerging from the luminous surface enters an entrance surface of the liquid crystal display and emerges from an exit surface of the liquid crystal display, wherein the lighting device is configured to control the liquid crystal display, in a targeted manner, in order to allow portions of the light impinging on the entrance surface to pass through the liquid crystal display and not to allow other portions of the light impinging on the entrance surface to pass through the liquid crystal display.

Lighting device for a vehicle

A lighting device for a motor vehicle, wherein the lighting device has a circuit board with a multiplicity of light-emitting diodes arranged thereon, a transparent optical layer, and a reflector element, wherein the reflector element is arranged between the circuit board and the optical layer, wherein the reflector element has multiple segments into which the reflector element is subdivided, wherein a segment is associated with each light-emitting diode so that light emitted by the light-emitting diodes can be reflected by the reflector element and can pass through the optical layer. Two light-emitting diodes are arranged in a segment. In addition, a lighting system and a motor vehicle are provided.

Lighting device for a motor vehicle

A lighting device for vehicles with a first lighting unit having a light source and a light beam surface for emitting light and with a second lighting unit containing a light source and a flat light guide having opposite flat sides and narrow sides connecting the same for backlighting the first lighting unit. The flat light guide of the second lighting unit has a backlighting section and a linear light section. The backlighting section is arranged behind the first lighting unit and a front flat side of the flat light guide in the backlighting section serves as a light decoupling surface for the light decoupling of a first part of the light coupled into the flat light guide. The linear light section is at least partially arranged next to the first lighting unit. A narrow side of the flat light guide serves as a light decoupling line.

Lighting device for vehicles

A lighting device for vehicles is provided, having a flat light guide containing two flat sides facing each other, one light input coupling surface for the entry of light at a light input coupling side of the flat light guide, one light output coupling surface for the output of light input at the light input coupling surface with the light output coupling surface arranged at one light output coupling side of the flat light guide. A specified light distribution (L) is thereby generated. The flat light guide further includes one narrow lateral surface connecting the flat sides with each other and extending from one lateral border of the light output coupling side, one collection surface adjacent to the light input coupling surface shaped in such a manner that a partial light beam of the entering light striking the collection surface is reflected in total towards the light output coupling surface without the partial light beam striking the narrow lateral surface. The light output coupling surface featuring a number of protrusions and depressions is alternately arranged transverse to the main beam direction (H), with the protrusions featuring at least two lateral slopes tapered at an acute angle (&#x3b1;) and a tip surface, that the tip surface is shaped in such a manner that a partial light beam which has been totally reflected from the collection surface and/or the flat sides and an additional partial light beam originating directly from the light input coupling surface are refracted at the tip surface to generate a central region (L) of light distribution (L), that the lateral slope of the protrusion is shaped in such a manner that another partial light beam of the input light striking the lateral slope is totally reflected towards the tip surface and exits the flat light guide at the tip surface to generate a lateral region (L, L) of light distribution (L).

A tail light with at least one light source and with a light guide body into which light generated by the light source can be coupled and out of which back-up light can be coupled, and light for illuminating the ground region can be decoupled. The light guide body has a light entry area through which light from the light source can be coupled into the light guide body. The light guide body has at least a first light exit area for the back-up light and a second light exit area for the light for illuminating the ground region, wherein the first and the second light exit areas may overlap. The light guide body has a first reflection surface at which a portion of the coupled-in light can be deflected in the direction of at least one of the light exit areas.
