Abstract

A light emitting diode includes a semiconductor body including an active region that produces radiation, a carrier body fastened to the semiconductor body on an upper side of the semiconductor body, the carrier body including a luminescence conversion material consisting of a ceramic luminescence conversion material, a mirror layer applied to the semiconductor body on an underside of the semiconductor body remote from the upper side, and two contact layers, a first contact layer of the contact layers connected electrically conductively to an n-conducting region of the semiconductor body and a second contact layer of the contact layers connected electrically conductively to a p-conducting region of the semiconductor body.
