PROBLEM TO BE SOLVED: To improve a lighting device having a plurality of semiconductor light sources at low cost. SOLUTION: In the lighting device having a plurality of semiconductor light sources arranged on a support body, each of the light of the light sources enters into a predetermined light guide in a fixed angle for the normal plane of the support body so as to couple thereto. The light guide is constructed so as to equip a light reflection plane and a light emission plane in which the envelope surface of the light reflection plane forms a curved surface segment.

Abstract:
The invention relates to a method for producing an optical fibre or an optical coupling-out structure for light comprising a coupling-out surface with light coupling-out structures, by means of an injection-moulding process. The light coupling-out structures are created by the laser removal of the injection-mould material, or the material of the optical fibre or coupling-out element that have already been injection moulded.
