  • Patent number: 11760929
    Abstract: The invention relates to a conversion element comprising a wavelength-converting conversion material, a matrix material in which the conversion material is inserted, and a substrate on which the matrix material and the conversion material are directly arranged, the matrix material comprising at least one condensed sol-gel material selected from the following group: water glass, metal phosphate, aluminium phosphate, monoaluminium phosphate, modified monoaluminium phosphate, alkoxytetramethoxysilane, tetraethyl orthosilicate, methyltrimethoxysilane, methyltriethoxysilane, titanium alkoxide, silica sol, metal alkoxide, metal oxane or metal alkoxane, the conversion element being arranged in the beam path of a laser source, the conversion element being mounted in a mechanically immobile manner in relation to the laser source, and the radiation of the laser source being dynamically arranged in relation to the conversion element.

  • Publication number: 20220013697
    Abstract: A method for producing a conversion element comprising the following steps is described: providing a conversion layer having a matrix, in which phosphor particles are brought in, the phosphor particles comprising a host lattice having activator ions and being concentrated in a enrichment zone, providing a compensation layer having the matrix, in which compensation particles are brought in, which comprise the host lattice and are concentrated in a enrichment zone, and joining the conversion layer and the compensation layer in such a way that the enrichment zone of the conversion layer and the enrichment zone of the compensation layer are arranged symmetrically to one another with respect to a symmetry plane of the conversion element conversion element and a component are also specified.
