Radiation-emitting component

A radiation-emitting component includes a radiation source including at least one semiconductor layer sequence that generates radiation; an optical waveguide device disposed downstream of the radiation source; and a conversion element for radiation conversion disposed downstream of the optical waveguide device, wherein radiation is emittable from the radiation source via an emission surface and couplable into the optical waveguide device, radiation is couplable from the optical waveguide device into the conversion element via an input surface, and the emission surface of the radiation source is larger than the input surface of the conversion element.
