Abstract:
1. A car lighting unit comprising: a reflector, a light source arranged to generate light, wherein the reflector circumferentially surrounds the light source and has a reflector opening, the reflector being arranged to reflect at least part of the light from the light source through the reflector opening, a daylight 3D hologram arranged to receive daylight and generate a source-unrelated holographic 3D image by daylight, wherein the source-unrelated 3D hologram is a reflective 3D hologram comprised by the reflector, the reflector further comprising an optical opening arranged to guide away, as hologram feed light, at least part of the light from the light source, a source-related 3D hologram, external from the reflector and arranged to receive the hologram feed light via the optical opening and generate a source-related holographic 3D image, said car lighting unit being constructed to generate a beam of light and the source-related holographic 3D image by light from the light source; and an optical unit defining an optical chamber arranged to receive the hologram feed light via optical opening, the optical chamber further comprising a reflector arranged to reflect at least part of the hologram feed light in the direction of the source-related 3D hologram.
