  • Patent number: 12600232
    Abstract: A display device for the interior of a vehicle comprises light sources, light guides, and holograms. The light guides are arranged next to one another and each has an entrance surface and a reflective area. Each light source emanates light that enters the entrance surface of an associated light. At least one of the holograms is arranged at or in each light guide. The light emanated by each light source enters the entrance surface of the associated light guide in a direction of the reflective area of the associated light guide, is reflected by the reflective area of the associated light guide in a direction of the hologram of the associated light guide, and interacts with the hologram of the associated light guide.

  • Patent number: 12467601
    Abstract: A surface light guide for a light of a motor vehicle. The surface light guide includes a light coupling section which is directly or indirectly connected to a light decoupling section. The light decoupling section includes a first flat side, a second flat side which is arranged opposite to the first flat side, a light decoupling surface which is arranged on the first flat side, and a decoupling structure which is arranged on the first flat side or on the second flat side. The decoupling structure has a plurality of individual and spaced-apart light decoupling elements. The decoupling structure deflects light rays which are coupled in by an illuminant so that deflected light rays are emitted through the light decoupling surface. The light coupling section couples in light rays from the illuminant and mixes the coupled-in light rays.
