MOTOR VEHICLE LIGHTING DEVICE WITH AN OPTICAL FIBER HAVING A COUPLING LENS AND A TRANSPORT AND CONVERSION LENS

摘要

A motor vehicle lighting device is proposed, having a light source, and having an optical waveguide, which has a coupling lens, which has at least one reflector, wherein the optical waveguide has first and second planes that are perpendicular to one another, and intersect, and wherein the lines of intersection are each defined by a light beam emitted from the reflector. The device is distinguished in that a 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 not altered, or is altered less strongly, and in that the optical waveguide has a transport and transformation lens, wherein the coupling lens and the transport and deflection lens are separate components.

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 in 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 transformation 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.
