A display device for a motor vehicle is provided. The display device includes at least one display with a display surface for displaying content via a plurality of pixels. The display device comprises a light-guiding lens with at least one entry surface and an exit surface. During operation of the display device the light emitted from the display surface enters the light-guiding lens through the at least one entry surface and is emitted by an exit surface, such that the content is shown on the exit surface. In one embodiment, the exit surface features a different shape. In another embodiment, the exit surface is a different size than the at least one display surface. In another embodiment, the display device comprises several displays with display surfaces at distances to each other, and the light-guiding lens features merely one exit surface or several exit surfaces directly adjoining each other.

A lighting device is provided for a motor vehicle. The lighting device comprises at least one imaging component with at least one active surface, on which imaging elements for the generation of pixels of a light distribution are arranged matrix-like. The lighting device further comprises a light-guiding optics having at least one entry surface and one exit surface. During operation of the lighting device, the light emanating from the at least one active surface enters the light-guiding optics through the at least one entry surface and exits the light-guiding optics through the exit surface. The exit surface has a different shape and/or a different size than the at least one active surface, and/or a plurality of active surfaces and only one exit surface or a plurality of adjacent exit surfaces are provided.

Lighting device for a motor vehicle

A lighting device for vehicles, and in particular headlamps, having a light source unit, and having a holographic unit for the generation of a given light distribution. The holographic unit has a hologram on the basis of a photo-sensitive material, onto which the holographic information is applied by means of an exposure process. The hologram is formed by a multitude of hologram segments. The hologram segments are each assigned a separate light source of the light source unit. The hologram segments serve to generate the given light distribution. Herein, holographic information is applied to the hologram segments depending on different wavelengths and different angles of the light source assigned to the hologram segments.

Lighting device for vehicles

A lighting apparatus for vehicles with a housing sealed by a transparent covering panel, containing a light source unit and an optical unit for producing a predetermined light function, wherein the optical unit has a hologram element and/or diffractive element in which diffraction information for producing the light function is contained, wherein optics are disposed downstream of the hologram element and/or the diffractive element in the light beam path, so that light of different orders of diffraction emerging from the hologram element and/or the diffractive element produce different light functions.
