Abstract: A lighting system includes an optical unit. The optical unit includes at least one light guide, which is provided for at least one light source. The lighting system further includes a retaining frame for the optical unit, via which frame the optical unit is fastened to a printed circuit board including the at least one light source, and a spacer for positioning the optical unit, which spacer is arranged between the retaining frame and the printed circuit board, the spacer having at least one continuous bearing opening in order to receive the at least one light guide. At least one guide recess is formed on the edge of the at least one bearing opening and at least one support face is provided on the edge, on which support face the light guide introduced into the bearing opening can be supported.

Abstract: In various embodiments, a lighting system is provided. The lighting system includes an optical unit having a plurality of light guides which are respectively provided for at least one light source and which respectively have an input coupling face. On the output side, the light guides are connected via a common connecting portion of the optical unit, the connecting portion having an output face, pointing away from the light guides, for the light emerging from the light guides. The lighting system further includes a holding frame for the optical unit, by means of which the optical unit is fastened to a printed circuit board, having the light sources, of the lighting system.
