  • Patent number: 7288606
    Abstract: A casting resin compound as an assembly and encapsulation material for electronic and optoelectronic component parts, modules and components, for example for casting out optoelectronic components on the basis of acid anhydride-curable epoxy compounds, particularly bisphenol A-diglycidyl ether, contains multi-functional epoxy novolak resins, particularly an epoxy cresol novolak. This casting resin compound exhibits a clearly increased glass transition temperature, is suitable for mass-production, exhibits no health deteriorations, and supplies SMT-capable products that can be utilized in the automotive sector.

  • Patent number: 7276736
    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 ?m and a mean grain diameter d50?5 ?m.

  • Patent number: 7151283
    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.

  • Publication number: 20060244000
    Abstract: A surface-mountable light-emitting diode light source is described, in which the leadframe-bends toward the rear side of the package that are required for surface mounting lie within a transparent plastic molded body. Also described is a method of producing a mixed-light, preferably white-light source on the basis of a UV- or blue-emitting semiconductor LED. The LED is mounted on a leadframe, a transparent plastics molding composition is mixed with a conversion substance and possibly further fillers to form a molding composition. The leadframe is encapsulated, preferably by the injection-molding process, with the molding composition in such a way that the LED is surrounded on its light-exiting sides by the molding composition.
