Light conductor with a ribbon-shaped light emitting area

A light conductor (10) with in input coupler (24, 26) which is arranged in such a way that divergent incident light is coupled into the inside of the light conductor in such a way that the coupled in light (12, 14) inside of the light conductor is distributed into a first layer, parallel layers, and into second layers, whereby each second layer is spanned by a perpendicular of the first layer and by a line located in the first layer, and with a light emitting area (18), characterized in that the input coupler is designed so that light is coupled in such a way that it has a lower divergence in the second layers than in the first layers and that the light conductor consists of a first deflection area between the input coupler and the light emitting area (18), which redirects light emitted from the input coupler incident on the deflection area (36) in an angle which is at least as big as the product of the value of the critical angle of the total internal reflection and the factor 2 and whereby the light conductor consists of further deflection areas (38) which are illuminated with light emitted from the first deflection area and which direct the incident light from the first deflection area into a preferred direction (z) for further common deflection areas.
