An optoelectronic device with a mixture including silicone and a fluoro-organic additive is disclosed. In an embodiment the device includes at least one radiation-emitting or radiation-detecting semiconductor and a mixture including silicone and a fluoro-organic additive. The mixture may be a component of at least one of the following elements: a package body element surrounding the at least one semiconductor at least in places, a radiation-guiding element arranged in a beam path of a radiation emitted by the semiconductor or detected by the semiconductor, a heat-conducting element configured to conduct heat emitted by the semiconductor or received by the semiconductor, or an adhesive element.

Optoelectronic device with a mixture having a silicone and a fluoro-organic additive

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.

Light-radiating semiconductor component with a luminescence conversion element

Disclosed is a wavelength-converting converter material comprising at least one wavelength-converting phosphor comprising phosphor particles, wherein a portion of said phosphor or all of said phosphor is present in the form of nanoparticles. Also disclosed is a light-emitting optical component comprising such a converter material and a method for producing such components.

Wavelength-converting converter material, light-emitting optical component, and method for the production thereof

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 &#x2266;20 &#x3bc;m and a mean grain diameter d&#x2266;5 &#x3bc;m.

Wavelength-converting casting composition and light-emitting semiconductor component

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.

Surface-mountable light-emitting diode light source and method of producing a light-emitting diode light source

To secure an optical lens over an optoelectronic transmitter or receiver, it is proposed to use a UV-initiated or photoinitiated, cationically curing epoxy resin, by means of which the bonded joint can be set and thereby fixed in a few seconds. Also proposed, for use as adhesives, are resin compositions that can be applied as liquids, are optically matched, and are optimized for durable, reliable use in optoelectronic components and for the large-scale manufacture thereof.

Optoelectronic component and method for the production thereof

A radiation-emitting surface-mountable component has a light-emitting diode chip mounted on a leadframe. A molding material encapsulates the leadframe and the light-emitting diode chip.

Light-radiating semiconductor component with a luminescene conversion element

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.

Wavelength-converting casting composition and white light-emitting semiconductor component

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 phosphorous group of the general formula ABX:M, and the luminous substance pigments have particle sizes &#x2266;20 &#x3bc;m and a mean grain diameter d&#x2266;5 &#x3bc;m.
