  • Patent number: 11914173
    Abstract: The invention relates to a reflector for a vehicle, which includes a main body having a plurality of reflection prisms arranged next to each other for each reflecting light. Each reflection prism has a reflection direction along which the reflection prism reflects the light. The main body has first reflection prisms having a first reflection direction and second reflection prisms having a second reflection direction different from the first reflection direction. The second reflection prisms form at least one symbol.

  • Publication number: 20230173978
    Abstract: The described examples relate to a lighting device for a motor vehicle with multiple optical fibers and multiple further fibers, which are woven to a two-dimensional fiber fabric. The multiple further fibers may be formed as multiple further optical fibers or as multiple non-optical fibers. The fiber fabric may be formed corresponding to a developed surface of multiple sides of a preset three-dimensional body, which may be generated by cutting and by selectively separating the multiple optical fibers and the multiple further fibers that are woven with each other, at a distal cut end of the fiber fabric.

  • Patent number: 10800326
    Abstract: A motor vehicle, comprising at least one linear lighting device for directly or indirectly lighting a vehicle interior. The at least one lighting device extends, at least in some sections, horizontally along at least one component of the motor vehicle. The motor vehicle additionally comprises a position-sensing unit for sensing ego information describing a position and an orientation of the motor vehicle. The at least one lighting device is divided horizontally into a plurality of lighting segments, each having a fixed emission profile. The motor vehicle has a control device, configured to: determine a direction of the destination in relation to the motor vehicle; select a sub-group of the plurality of lighting segments comprising at least one lighting segment to be activated; and activate the at least one lighting segment belonging to the sub-group according to lighting brightness or lighting color of the at least one lighting segment.

  • Patent number: 10645529
    Abstract: A motor vehicle is disclosed that includes at least one linear lighting means for directly and/or indirectly lighting a vehicle interior. A position-sensing unit senses ego information describing a position and an orientation of the motor vehicle. A control device determines, from location information describing the position of a person, and from the ego information, direction information describing a direction of the person in relation to the motor vehicle (1), selects, in accordance with the direction information, a sub-group of lighting segments that includes at least one lighting segment to be activated, and activates the lighting segment belonging to the sub-group in accordance with a configuration, which specifies the lighting brightness and/or the lighting color of the lighting segment, and which visualizes the position of the person.
