Abstract:
A holographic lighting device for vehicles with a light source for emitting light and with an optical unit containing a hologram element which is set up in such a way that a hologram image is generated in a given field of view. In the hologram element, such hologram information is inserted that by changing a viewing angle from a center position of the viewer, in which the viewer is arranged vertically to a surface of the hologram element, in the direction of a lateral boundary position of the viewer in which a boundary of the field of view is reached, at least in some areas, a distance between the generated hologram image and the hologram image in the center position is increased or is rotated by a vertical and/or horizontal axis, and/or a brightness of the hologram image is reduced.
