  • Patent number: 4899260
    Abstract: A body of a material as clear as glass, is arranged behind the parts to be illuminated and passes light beams from at least one illumination source to the areas to be illuminated and reflects the beams by deflection at reflection surfaces to the individual areas to be illuminated. The optical conductor body (1) includes a plate (1) with a substantially planar surface, openings (7, 8, 9) extending transversely through the plate (1), the walls (7a, 8a, 9a) of these openings extending at right angles to the central plane (5) of the plate at an acute angle to the course of the light beams and having reflection surfaces. The light beams are passed parallel to the central plane (5) of the plate within the plate, the light beams being reflected into recesses provided as output areas and being reflected out of these recesses by means of reflection surfaces (10b) inclined with repsect to the central plane (5) of the plate.
