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).
Claims10
A car lighting unit comprising:
- a reflector,
- a light source arranged to generate light, wherein the reflector circumferentially surrounds the light source and defines a reflector opening, the reflector being arranged to reflect at least part of the light from the light source through the reflector opening, and
- a 3D hologram disposed proximate to the light source such that, in operation, the light source generates a holographic 3D image and a separate beam of light, which beam of light providing a signaling function, and wherein the ratio of the luminous intensity related to the holographic 3D image to the total luminous intensity of the light generated by the lift source is in the range of 0.01-0.1.
A car lighting unit comprising:
- a reflector,
- a single light source arranged to generate light, wherein the reflector circumferentially surrounds the light source and defines a reflector opening, the reflector being arranged to reflect at least part of the light from the light source through the reflector opening, and
- a 3D hologram disposed proximate to the light source such that, in operation, the light source generates a holographic 3D image and a separate beam of light, which beam of light providing a signaling function, and wherein the ratio of the luminous intensity related to the holographic 3D image to the total luminous intensity of the light generated by the light source is in the range of 0.01-0.1.
