Patents by Inventor Ulrike Reeh

Ulrike Reeh has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9196800
    Abstract: 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: Grant

    Date of Patent: November 24, 2015
    Assignee: OSRAM GmbH

  • Patent number: 5618872
    Abstract: 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.

  • Patent number: 5492981
    Abstract: A casting resin system containing epoxyalkylsiloxane is provided for covering optoelectronic components. The casting resin system includes a resin constituent containing a mixture of epoxyalkylsiloxanes and cycloaliphatic epoxy resins. The casting resin system can be hardened with a polycarboxylic acid anhydride as a hardener component to form molding materials that are transparent and color-stable.
