Abstract
A lighting device for vehicles, including a housing, which is closed by a transparent cover panel and contains a holographic lamp unit having has a light source unit, and including an optical unit containing a holographic element for generating a holographic luminous surface, the holographic element being disposed between the light source unit and the cover panel, so that it may be back-lit with the aid of the light source unit, and the holographic unit has a structure such that the holographic luminous surface is disposed between the holographic element and the cover panel, forming a distance from the holographic element and the cover panel.
Claims13
A lighting device for vehicles, the lighting device comprising:
- a housing that has a transparent cover panel;
- a holographic lamp unit including a light source unit and a holographic element for creating a holographic luminous surface,
- wherein the holographic element is arranged between the light source unit and the cover panel so that the holographic element is adapted to be back-lit via the light source unit, and
- wherein the holographic element has a structure such that the holographic luminous surface is arranged between the holographic element and the cover panel, the holographic luminous surface being spaced apart from the holographic element by a first distance and being spaced apart from the cover panel by a second distance, and
- wherein the holographic luminous surface is a floating, virtual luminous surface that runs substantially parallel to the holographic element.
