Abstract

A radiation-emitting component is disclosed. In embodiments a component includes a radiation-emitting semiconductor chip having a radiation exit area including a side face and a main face, a conversion element having a radiation exit area including a side face and a main face, and a first reflection element disposed downstream of the conversion element and the radiation-emitting semiconductor chip, wherein a ratio of a sum of the radiation exit areas of the radiation-emitting semiconductor chip to a sum of the radiation exit areas of the conversion element is greater than 1, wherein the conversion element adjoins the radiation-emitting semiconductor chip, wherein the radiation-emitting semiconductor chip is configured to generate primary radiation, wherein the conversion element is configured to convert the primary radiation into secondary radiation, and wherein the primary radiation and the secondary radiation leave the radiation-emitting component exclusively through the first reflection element.
