In various embodiments, a lighting apparatus is provided. The lighting apparatus includes a primary light generating device configured to generate a primary light beam, a phosphor body configured to at least partly convert the primary light beam into secondary light, and a shell-shaped reflector situated in a primary light path between the primary light generating device and the phosphor body. The reflector has in at least one part of its reflection surface a plurality of grooves which run openly in their longitudinal extent and which are arranged parallel to one another.

Lighting apparatus

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.
