Abstract

An electromagnetic radiation emitting assembly includes a carrier, an electromagnetic radiation emitting component arranged above the carrier, and a potting material at least partly surrounding the electromagnetic radiation emitting component and into which are embedded phosphor that converts the electromagnetic radiation and heat-conducting particles that conduct heat arising during operation of the electromagnetic radiation emitting assembly, wherein a phosphor concentration in the potting material near the electromagnetic radiation emitting component is greater than a particle concentration of the heat-conducting particles in the potting material near the electromagnetic radiation emitting component, and a particle concentration of the heat-conducting particles in the potting material near the electromagnetic radiation emitting component is greater than in the potting material remote from the electromagnetic radiation emitting component.
