Abstract
A lighting device (31), in particular a rear luminaire, for a vehicle (30) is provided. The lighting device (31) has a hologram (34) and a light source (32) for illuminating the hologram (34). An image, more particularly a real image (35), is thereby generated, which can also lie outside the physical boundaries of the lighting device (31).
Claims9
A lighting device configured as a front headlight or rear luminaire for a vehicle, comprising:
- a multiplicity of individual holograms that, when illuminated, generate a corresponding multiplicity of real individual images having different spatial orientations;
- and
- a light source configured to illuminate the multiplicity of individual holograms;
- wherein, with respect to the lighting device being in its installed orientation in the vehicle, the multiplicity of individual holograms is configured to generate the corresponding multiplicity of real individual images at corresponding locations in free space at the front or rear of the vehicle that are outside physical boundaries of the lighting device.
