Abstract:
A lighting device is disclosed comprising a plurality of semiconductor light sources disposed on a carrier, wherein the light from the light sources is coupled into assigned lightguides at a set angle to the surface normals of the carrier and the lightguides are provided with reflecting and light exit faces such that the envelope of the light outcoupling faces forms a curved surface segment.
