  • Publication number: 20050029929
    Abstract: The invention proposes an arrangement of luminescent materials for excitation by means of a radiation source and involving the use of a luminescent material having a Ce-activated garnet structure A3B5O12, in which the first component A contains at least one element from the group consisting of Y, Lu, Se, La, Gd, Sm and Tb and the second component B represents at least one of the elements Al, Ga and In, and a plurality of the luminescent materials are mixed together. An associated wavelength-converting casting compound and an associated light-source arrangement are further proposed.

  • Publication number: 20050014302
    Abstract: The invention describes a radiation-emitting semiconductor component with a luminescent conversion element, at which the semiconductor body is placed in a recess of the base body. A cup-like area is molded inside of the recess around the semiconductor body, which contains the luminescent conversion element and coats the semiconductor body. The cup-like portion is formed as indentation inside of the recess or as annular border on the base of the recess.

  • Publication number: 20040084687
    Abstract: The wavelength-converting casting composition is based on a transparent epoxy casting resin with a luminous substance admixed. The composition is used in an electroluminescent component having a body that emits ultraviolet, blue or green light. An inorganic luminous substance pigment powder with luminous substance pigments is dispersed in the transparent epoxy casting resin. The luminous substance is a powder of Ce-doped phosphors and the luminous substance pigments have particle sizes ≦20 &mgr;m and a mean grain diameter d50≦5 &mgr;m.

  • Publication number: 20040016908
    Abstract: The wavelength-converting casting composition is based on a transparent epoxy casting resin with a luminous substance admixed. The composition is used in an electroluminescent component having a body that emits ultraviolet, blue or green light. An inorganic luminous substance pigment powder with luminous substance pigments is dispersed in the transparent epoxy casting resin. The luminous substance is a powder of garnets, thiogallates, aluminates, or orthosilicates doped with rare earths, and preferably Ce-doped phosphors. The luminous substance pigments have particle sizes≦20 &mgr;m and a mean grain diameter d50<5 &mgr;m.

  • Patent number: 6669866
    Abstract: A phosphor for light sources, the emission from which lies in the short-wave optical spectral region, as a garnet structure A3B5O12. It is activated with Ce, the second component B representing at least one of the elements Al and Ga, and the first component A is terbium or terbium together with at least one of the elements Y, Gd, La and/or Lu. In a preferred embodiment, a phosphor having a garnet of structure (Tb1−x−yRExCey)3(Al,Ga)5O12, where RE=Y, Gd, La and/or Lu; 0≦x≦0.5−y; 0<y<0.1 is used.
