Abstract:
A method for producing a light-emitting diode includes providing a light-emitting diode chip including a semiconductor body, and applying a luminescence conversion material to an outer area of the semiconductor body by thermal spraying such that at least part of electromagnetic radiation generated during operation of the light-emitting diode impinges on the luminescence conversion material, or providing a radiation-transmissive carrier, applying a luminescence conversion material to an outer area of the carrier by thermal spraying, and arranging the carrier at a radiation exit area of the light-emitting diode chip such that at least part of electromagnetic radiation generated during operation of the light-emitting diode impinges on the luminescence conversion material.
