1. A method of producing a light-emitting diode comprising:

  • providing a light-emitting diode chip comprising a semiconductor body,providing a radiation-transmissive carrier formed from one selected from the group consisting of ceramic material, semiconductor material, glass and plastic,applying a luminescence conversion material directly to an outer area of the carrier by cold gas spraying, andarranging the carrier at a radiation exit area of the light-emitting diode chip by a glass such that at least part of electromagnetic radiation generated during operation of the light-emitting diode impinges on the luminescence conversion material, wherein the glass has a low melting point and/or is formed by a sol-gel process,wherein the luminescence conversion material comprises at least one inorganic phosphor or at least one organic phosphor, the at least one inorganic phosphor is selected from the group consisting of garnets doped with rare earth metals, alkaline earth metal sulfides doped with rare earth metals, thiogallates doped with rare earth metals, aluminates doped with rare earth metals, orthosilicates doped with rare earth metals, chlorosilicates doped with rare earth metals, alkaline earth metal silicon nitrides doped with rare earth metals, oxynitrides doped with rare earth metals and aluminum oxynitrides doped with rare earth metals, and the at least one organic phosphor is selected from the group consisting of perylenes, benzopyrenes, coumarins, rhodamines, azo dye, terylene dye, quaterylene dye, naphthalimide dye, cyanine dye, xanthene dye, oxazine dye, anthracene dye, naphthacene dye, anthraquinone dye and thiazine dye.
