Abstract: A wavelength converter includes a converter layer for at least partly converting primary light of a first spectral composition into secondary light of a second spectral composition, an electrically insulating first insulation layer arranged below the converter layer, a mirror being arranged at the front side of said insulation layer facing the converter layer, at least one conductor track which is arranged at the first insulation layer and which extends laterally at a distance from the mirror, mutually spaced apart contacts extending through the first insulation layer, of which contacts in each case at least two contacts electrically connect a conductor track to a rear side of the first insulation layer, and mutually spaced apart electrically conductive solder connection volumes arranged below the first insulation layer, said solder connection volumes being electrically connected in each case to one of the contacts.

Abstract: A lighting apparatus including a light generating device and at least one light wavelength conversion element and also at least one light directing means is provided. The light generating device and the at least one light directing means are configured in such a way that linearly polarized light is generated and directed from different directions to the at least one light wavelength conversion element, such that the linearly polarized light impinges on a surface of the at least one light wavelength conversion element from different directions in each case at an angle of incidence which corresponds to a Brewster angle, wherein the polarization direction of the linearly polarized light is parallel to the plane of incidence thereof.

Abstract: According to the present disclosure, a converter device is provided. The device includes a phosphor element for converting a pump radiation into a conversion radiation and an excitation coil for producing an alternating magnetic field in which the phosphor element is arranged. The phosphor element has a conductor loop forming a coupling coil that is inductively coupled to the excitation coil such that the coupling coil and hence the phosphor element can be monitored by way of the inductive coupling.
