Claim Text:
1. A light conductor ( 10 ) with an 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 ) propagates inside the light conductor in planes that are parallel to a first plane, and in second planes, whereby each second plane is spanned by a perpendicular of the first plane and by a line located in the first plane, and with a light emitting area ( 18 ), said input coupler acting to produce light that is coupled in such a way that it has a lower divergence in the second planes than in the first planes, said light conductor including 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 first 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 a plurality of further deflection areas ( 38 ) which are illuminated with light emitted from the first deflection area and which each direct the incident light from the first deflection area into a preferred common direction of illumination (z) so as to produce a parallel, aligned and homogenous light beam from said light conductor.
