US Patent 9285102 Radiation-emitting component

A radiation-emitting component with a semiconductor body is intended for emitting electromagnetic radiation from its front side. The component also includes a reflective optical element. This optical element is intended to direct some of the radiation emitted by the semiconductor body, which impinges directly on the reflective optical element, into an outer region of a target zone. A refractive optical element is intended to focus the reflected fraction of the radiation into the outer region of the target zone and to focus the remaining fraction of the radiation into an inner region of the target zone.
