摘要： An illumination apparatus for a motor vehicle comprises: a light source, an optical waveguide with an incident surface and a reflective region; and a hologram arranged on or in the optical waveguide. The illumination apparatus is configured such that light emitted by the light source enters the incident surface of the optical waveguide in the direction of the reflective region, is reflected by the reflective region inside the optical waveguide in the direction of the hologram and interacts with the hologram. The average distance between the light source and the incident surface is at least half as great as the average distance between the reflective region and the hologram.

摘要： A lighting device for a motor vehicle is provided with numerous light sources. A flat waveguide has one entry surface and at least one exit surface. A cover panel is provided, and the light generated by the light sources enters the waveguide, at least in part, through the entry surface, the light entering through the entry surface exits, at least in part, through the at least one exit surface, and the light exiting the waveguide through the at least one exit surface at least partially exits the lighting device through the cover panel. A housing is provided that at least partially encases the numerous light sources, the waveguide, and the cover panel. The thickness of the lighting device in the direction perpendicular to the length and width of the waveguide is less than 20-mm where light exits the cover panel when the lighting device is in operation.

摘要： A lighting device for vehicles includes a light source unit containing numerous light sources, and includes a hologram unit containing numerous hologram segments for generating a predefined light distribution. The hologram segments form reflection hologram segments behind and/or next to the light source unit in the main beam direction (H) of the lighting device, such that light emitted from the light source strikes the reflection hologram segment at an acute angle (φ). Holographic diffraction information is stored in the reflection hologram segments for generating a signal light distribution. The light source unit contains just one printed circuit board or one printed circuit board substrate.

摘要： 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.
