Abstract
An illumination apparatus for a motor vehicle comprises: a light source, an optical waveguide with an incident surface and a reflective region; and a hologram arranged on or in the optical waveguide. The illumination apparatus is configured such that light emitted by the light source enters the incident surface of the optical waveguide in the direction of the reflective region, is reflected by the reflective region inside the optical waveguide in the direction of the hologram and interacts with the hologram. The average distance between the light source and the incident surface is at least half as great as the average distance between the reflective region and the hologram.
