Abstract
A method of producing a light-emitting diode includes providing at least one light-emitting diode chip, providing a suspension comprising a solvent and particles of at least one luminescent material, arranging the at least one light-emitting diode chip in the suspension, electrophoretically depositing the particles on an outer face of the at least one light-emitting diode chip, and completing the light-emitting diode.

A method of producing a light-emitting diode comprising:
- providing at least one light-emitting diode chip,
- providing a suspension comprising a solvent and particles of at least one luminescent material,
- arranging the at least one light-emitting diode chip in the suspension,
- electrophoretically depositing the particles on an outer face of the at least one light-emitting diode chip, and
- completing the light-emitting diode.
A light-emitting diode comprising at least one light-emitting diode chip comprising at least one outer face through which electromagnetic radiation generated in the light-emitting diode chip when said light-emitting diode chip is in operation leaves the light-emitting diode chip, and particles of at least one luminescent material electrophoretically deposited onto the outer face of the light-emitting diode chip.
A method of producing a light-emitting diode comprising:
- providing at least one light-emitting diode chip,
- providing a suspension comprising a solvent and particles of at least one luminescent material,
- arranging the at least one light-emitting diode chip in the suspension,
- electrophoretically depositing the particles on an outer face of the at least one light-emitting diode chip,
- providing a further suspension comprising a solvent and particles of at least one further luminescent material,
- arranging the at least one light-emitting diode chip at least in part in the suspension,
- electrophoretically depositing the particles of the at least one further luminescent material on an outer face of the at least one light-emitting diode chip,
- wherein the particles of the at least one luminescent material and the particles of the at least one further luminescent material on the outer face of the at least one light-emitting diode chip form a pattern of first regions with particles of a first luminescent material and second regions with particles of a second luminescent material.
