  • Patent number: 10018314
    Abstract: A lighting device for vehicles with an elongated light guide comprising an end face for the coupling-in of light, into which a light beam radiated from a light source can be coupled-in. The lighting device further comprises elements for the coupling-out of light for the deflection of the coupled-in light beam in the direction of a front skin surface of the elongated light guide, on which the light beam can be coupled-out for the generation of a given light function, such that the front skin surface of the elongated light guide is connected to a rear skin surface by means of a curved dispersion surface. At least one light directing element is arranged between a row of light sources and the light guide so that the light of the light sources arranged in a row can be coupled into the rear skin surface or the curved dispersion surface of the light guide.

  • Patent number: 9995451
    Abstract: The invention relates to a lighting device (10) according to the invention for a motor vehicle external light having a light conductor (12), which extends along a longitudinal extension direction (14) and has two end faces (16, 18), at least one first light source (20) for coupling light into one of the two end faces (16, 18) of the light conductor (12), a plurality of second light sources (22) for coupling light into the light conductor (12) vertically with respect to the longitudinal extension direction (14) of the light conductor (12), and a control unit for separate actuation of the at least one first light source (20) and of the plurality of second light sources (22).
