Abstract (en)
[origin: WO2004042271A2] The aim of the invention is to achieve an optimal illumination provided by a light guide having a structurally simple design. To this end, the reflecting surfaces (13, 14) are offset to one another while extending transversal to the beam direction of the lighting means (8, 11) and, when viewed in the beam direction, they join one another without forming, in essence, any gaps. As a result, no shadows are formed between the individual reflecting surfaces (13, 14) thereby enabling an optimal utilization of light emitted by the lighting means (8, 11). The inventive light guide is provided for lighting motor vehicles.
