Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
We claim: 1. A light-radiating semiconductor component comprising a semiconductor body having a semiconductor layer sequence comprising layers based on GaN and configured to emit electromagnetic radiation of a first wavelength range during operation of the semiconductor component; and a luminescence conversion element comprising at least one luminescent material, wherein the first wavelength range comprises at least light from the blue spectral range and the luminescence conv…
