Various embodiments may relate to a lighting apparatus, including at least one primary light source for generating primary light, a reflector having two spaced-apart focal spots, a guiding optical unit disposed downstream of the at least one primary light source and serving for guiding the primary light to a first focal spot of the reflector, and a conversion device for at least partly converting the primary light into secondary light having a different wavelength which is situated at the second focal spot. The reflector has a first reflective partial region, to which the two focal spots are assigned, and a second reflective partial region, which is a partial region retroreflective for the second focal spot. The primary light emitted by the at least one primary light source is incident on the first partial region.
