Abstract A holographic lighting apparatus includes at least two channels for the respective associated lighting functions. Each channel includes an edge-lit arrangement with an incoupling surface for coupling light from a light source into the arrangement, and an outcoupling surface; and a light source. The edge-lit arrangements of the channels are all included in a monolithic component having a common outcoupling surface, and each channel is arranged so as to be rotated about a surface normal of the outcoupling surface along an azimuthal arrangement angle. The component has at least one holographic structure for generating the lighting function of the relevant channel when said structure is illuminated by the light source of the channel. Also provided are a vehicle including a corresponding lighting apparatus, the use of the lighting apparatus as a display in a vehicle, and the lighting apparatus as an LED collimator.
