Abstract

See full text

Various embodiment may relate to a lighting device, including a light mixing element having a light entry surface and a light exit surface, multiple light sources, the primary light of which can be is radiated onto the light entry surface, a wavelength conversion unit having a carrier, on which a luminescent volume is arranged, which luminescent volume can be is illuminated by means of the primary light emitted by the light exit surface, and at least one decoupling optical unit for forming useful light emitted by the wavelength conversion unit, which has at least one non-imaging safety region. The multiple light sources radiate the primary light thereof at an angle onto the light entry surface. The at least one safety region occupies a position on the decoupling optical unit which corresponds to a region of high intensity of the primary light in the case of remote luminescent volume.
