Claim Text:
1. A motor vehicle lighting device having a light source and having an optical waveguide, which has a first side and a second side lying opposite the first side, and narrow sides lying between an edge of the first side and an edge of the second side, and connecting the first side to the second side, and which has a coupling lens that couples and transforms the light from the light source, wherein the coupling lens has at least one reflector, which transforms light emitted from the light source into a solid angle, and wherein the optical waveguide has imaginary first planes and second planes, which are defined in that the first and second planes are perpendicular to one another, and intersect, wherein the lines of intersection are each defined by a light beam emitted from the reflector, wherein the transformation by the coupling lens occurs such that an aperture angle of propagation directions of the light beams lying in the second planes is reduced, and the aperture angle of propagation directions lying in the first planes is altered less strongly than the aperture angle of the propagation directions lying in the second planes, and wherein the optical waveguide has a transport and deflection lens, which transports the light transformed by the coupling lens to a light emission surface of the optical waveguide, wherein the coupling lens and the transport and deflection lens are separate components, wherein the coupling lens is designed as a circular-edged component having a convex light decoupling surface that is congruent to a concave light coupling surface of the transport and deflection lens, and these surfaces adjoin one another directly, in the direction of the light beams passing through them and wherein the coupling lens has a first reflector at its center, which has the form of a funnel-shaped recess having a circular base surface.
