Patent number: 9196800Abstract: The light-radiating semiconductor component has a radiation-emitting semiconductor body and a luminescence conversion element. The semiconductor body emits radiation in the ultraviolet, blue and/or green spectral region and the luminescence conversion element converts a portion of the radiation into radiation of a longer wavelength. This makes it possible to produce light-emitting diodes which radiate polychromatic light, in particular white light, with only a single light-emitting semiconductor body. A particularly preferred luminescence conversion dye is YAG:Ce.Type: GrantFiled: November 2, 2009Date of Patent: November 24, 2015Assignee: OSRAM GmbHInventors: Ulrike Reeh, Klaus Höhn, Norbert Stath, Günter Waitl, Peter Schlotter, Jürgen Schneider, Ralf Schmidt

Patent number: 5618872Abstract: The invention relates to the use of momodisperse, non-porous, spherical particles based on SiO.sub.2, TiO.sub.2, ZrO.sub.2, Al.sub.2 O.sub.3, V.sub.2 O.sub.5, Nb.sub.2 O.sub.5 or mixed systems thereof, which are optionally modified on the surface by covalently bonded organic groups, as fillers in organic matrix materials, the refractive index of the particles being adapted to the refractive index of the organic matrix according to the use.Polymeric or polymerizable systems which comprise these particles can be used, for example, as embedding compositions for optical, electro-optical and optoelectronic components. Such embedding compositions show an improved optical homogeneity. Light-emitting diodes produced with them are distinguished, inter alia, by an improved light yield.Type: GrantFiled: December 9, 1994Date of Patent: April 8, 1997Assignees: Merck Patent Gesellschaft mit beschrankter Haftung, Siemens AGInventors: Ludwig Pohl, Kurt Marquard, G unter Waitl, Ulrike Reeh, Ernst Wipfelder
