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.
