  • Publication number: 20060250808
    Abstract: A vehicle fitted with at least one tail light (1) and a rear license plate (8) to be illuminated, a light source (2) for emitting a light beam to a optical waveguide (4) disposed adjacent the light source is provided, said optical waveguide being provided with an input surface (5) facing towards the light source for inputting at least part of the light beam from the light source, as well as with at least one output surface (6) for outputting a light beam that is being passed through the optical waveguide to the license plate and/or the at least one tail light. The light source can be a light emitting diode.

  • Publication number: 20050231981
    Abstract: An illumination system, preferably for illumination in a car, comprising at least one plain or slightly curved, solid light guide (4) made of transparent material, said light guide receiving light from a light (2) source and being provided with means (5, 6) for extracting light from said light guide, the means for extracting light from said light guide have. Reflecting surfaces (7, 8, 9, 10) the slopes of which are varied as a function of the position of the extracting means in the light guide as well as the position of a reading plane, so as to direct the light flux to a desired reading plane position. Preferably the illumination system a laminated structure of light guide layers, said layers being formed of a light guide layer for diffuse homogeneous illumination (1) and at least one light guide layer (4) for spot illumination of a reading plane.

  • Publication number: 20050083493
    Abstract: An electric lamp (1) comprising an elliptical reflector body (3) with a light emission window (5) and with a light-transmitting cover (11) positioned in the light emission window. A light chamber (7) is defined by the reflector body, in which chamber a light source (13) is positioned in a first focus (F1) of the reflector body. A second focus (F2) of the reflector body is located outside the light chamber and at an end (19) of an optical waveguide (17). The cover is provided with IR-reflecting means (15) and is parabolically or elliptically shaped, the cover having a focus (Flid) which is located on the light source.
