Abstract: A radiation emitting component and a method for producing a radiation emitting component are disclosed. In an embodiment a radiation emitting component includes a radiation emitting semiconductor chip having an active zone configured to generate electromagnetic radiation of a first wavelength range, a reflector having side walls and a bottom surface and a conversion layer comprising a first phosphor configured to convert the electromagnetic radiation of the first wavelength range into electromagnetic radiation of a second wavelength range, wherein the conversion layer is located at the side walls of the reflector, wherein the conversion layer has a cross-sectional area, which decreases from the bottom surface of the reflector to a radiation exit surface of the component, and wherein the reflector is filled with a conversion element comprising a second phosphor configured to convert electromagnetic radiation of the first wavelength range into electromagnetic radiation of a third wavelength range.
