Abstract

A radiation-emitting semiconductor component, comprising a semiconductor body which emits a primary light, a luminescent conversion element which emits fluorescent light, in which the luminescent conversion element comprises a suspension of a luminous substance in a matrix material, wherein the luminescent conversion element is in direct contact with a part of the surface of said semiconductor body, and wherein the fluorescent light emitted from said luminescent conversion element is approximately half the total emission of the light of the radiation-emitting semiconductor component.
