The present invention relates to a method of manufacturing light-emitting diodes in which a light emitted from a semiconductor chip (3) is converted into visible light by a ceramic phosphor substrate (1) and emitted accordingly, whereby a ceramic phosphor substrate (1) is sintered to a sintered density (S1), the ceramic phosphor substrate (1) is coated with a ceramizable powder and a locally selective sintering is carried out by means of a laser beam, wherein the precursor layer (7) forms an optically active ceramic surface structure (9) on the ceramic phosphor substrate and provides. In this way, optical properties, in particular scattering properties on the surface, can be adjusted in a targeted manner, so that production, in particular of white light-emitting diodes, is effectively simplified. |
