Abstract

A lighting arrangement comprises an optical apparatus (4) with a radiation outlet surface (41) and an optoelectronic component (2) for producing radiation, with an element (3) which is formed like a reflector being formed. The shape and arrangement of the element are suitable for deflecting radiation generated in the component through the radiation outlet surface, and the element is designed to specifically absorb this radiation. The lighting arrangement is preferably intended for particularly homogeneous back-lighting of display apparatuses such as liquid crystal displays (LCDs).
