Abstract:
The invention provides a car lighting unit (1) comprising a reflector (10) and a light source (20) arranged to generate light (21). The reflector (10) circumferentially surrounds the light source and the reflector has a reflector opening (11). The reflector is arranged to reflect at least part of the light from the light source through the reflector opening. The car lighting unit further comprises a 3D hologram (30). The car lighting unit is constructed to generate a beam of light (22) and a holographic 3D image (31), using light from the light source (20).
