Abstract

The invention relates to a lighting unit having a light source and a reflector. The light source has a primary light source, the radiance thereof being guided via a scattering optic (10) to an optical converter (20). There a secondary radiance is radiated back and output by the scattering optic acting as a secondary light source.
