Luminescent diode, comprises a light-emitting semiconductor chip embedded in a casting composition transparent for the emitted light

摘要

Luminescent diode comprises a light-emitting semiconductor chip (7) embedded in a casting composition transparent for the emitted light. The casting composition has a structure having a cross-section profile formed by tapered protrusions whose half-width value is smaller than the wavelength of the emitted light. An Independent claim is also included for a process for the production of the luminescent diode. Preferred Features: The chip is arranged in a housing (8) which is cast with the casting composition. The casting composition has a base casting made from an epoxy resin with a surface layer made from an inorganic-organic hybrid polymer or polymethylacrylate.
