    摘要: The invention relates to a lighting apparatus for generating light. A primary light generator generates primary light (6), which is converted by a light converting material (8) into secondary light (3), wherein the primary light is directed to a primary surface (9) of the light converting material. An enclosure (10) comprising a transparent cover (7) hermetically encloses the light converting material, wherein the transparent cover is transparent to the primary light and located on the primary surface of the light converting material. The enclosure increases the photostability of the light converting material. This allows increasing the intensity of the primary light by, for example, increasing the power of the primary light and, thus,of the secondary light, and/or by focusing the primary light onto a smaller area on the primary surface, thereby allowing decreasing the optical Étendue of the secondary light, without damaging the light converting material.
