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.

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.

Abstract: A composition comprises from 60-98 weight percent of a casting resin such as an epoxy resin, from 2-30 weight percent of an alcohol or sugar such as 3 (4), 8 (9)-bis(hydroxymethyl)tricyclo[5.2.1.02,6]decane, from 0.2 to 2.0 weight percent of a thermal initiator such as an onium salt, from 0.2-2.0 weight percent of a bonding agent such as 3-glycidyloxypropyltrimethoxysilane, from 0-3.0 weight percent of a flow improver, from 0.2-5.0 weight percent of a metal complex with an organic ligand such as an amino acid, acetate, carbonic acid, amine and acetylacetonate including zinc di-(2-ethylhexanoate) and from 0-4 weight percent of a thixotropic agent and/or a flow modifier.

Abstract: The wavelength-converting casting composition is based on a transparent epoxy casting resin with a luminous substance admixed.

Abstract: An epoxysiloxane condensate is modified by means of an in situ reaction with an organic compound, which is di-functional or multifunctional if warranted. By means of the disclosed method, the characteristics of epoxysiloxane condensates, epoxy resin mixtures, epoxy resin formulations and molded bodies manufactured therefrom can be varied easily and economically.

Abstract: To produce a mechanically firm glued connection between two surface regions of surfaces to be connected, a method is provided which provides each of the surfaces with surface regions having a peak-to-valley thickness of less than 0.3 &mgr;m and the surface regions are brought together in such a way that an intermediate space, which is filled with the glue, is produced therebetween and the space has a small average thickness of less than 0.31 &mgr;m and extends over a surface area of at least 20×20 &mgr;m2. The glue is preferably brought into the intermediate space by capillary action and contacts of high quality can be achieved with this method.

Abstract: The invention relates to a single-component adhesive system that consists at least of a casting resin, in particular of an epoxy casting resin, and a multivalent alcohol. The low-viscosity adhesive system can be microdosed, is stable in storage, is completely hardenable and is suitable for applications in which the dimensional tolerances are in the &mgr;m and sub-&mgr;m region.

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.
