Title:
SEMICONDUCTOR WHITE LIGHT SOURCE
Document Type and Number:
WIPO Patent Application WO/2004/038815
Kind Code:
A1
Abstract:
The inventive semiconductor white light source comprises a semiconductor radiating crystal (1) which is based on a multicomponent Al-In-Ga-N system and generates the light in the blue-violet spectral range, and a coating containing a phosphor (5) which absorbs a part of light emitted by the crystal and gives off light in the yellow spectral range. An oxonitride $g(a)-sialon material activated with a divalent europium is used in the form of a phosphor.
