In various embodiments, a lighting apparatus is provided. The lighting apparatus includes at least one light generating device configured to generate at least one polarized primary light beam; and at least one luminescent body, separated from the at least one light generating device, which can be illuminated by the polarized primary light beam. The at least one polarized primary light beam strikes a surface of the luminescent body at a Brewster angle, and is p-polarized in relation to this surface.
