US 2015/0146302 A1 · LIGHTING DEVICE

Abstract

A lighting device may include at least one light source arrangement for generating primary light; at least one light wavelength conversion element for converting primary light into secondary light; and a filter apparatus disposed optically downstream of the at least one light wavelength conversion element and serving for filtering out primary light. The at least one light source arrangement and the at least one light wavelength conversion element are embodied or correspondingly embodied light directing means are provided in such a way that part of the primary light generated by the at least one light source arrangement impinges on the at least one light wavelength conversion element and part of the primary light generated by the at least one light source arrangement is directed past the at least one light wavelength conversion element.
