Effizienter Wellenlaengenkonverter und Leuchtvorrichtung mit einem effizienten Wellenlaengenkonverter

DE 102008027339 A1 UPAB: 20091118 NOVELTY - The converter (1) has a heat conducting lattice, a heat conducting diamond layer (3) in the form of substrate, and a luminescent material for partial conversion of an electromagnetic primary radiation into a secondary radiation. The wavelength of the secondary radiation is different from that of the primary radiation. The lattice and the diamond layer are arranged within an area of the converter. The area is provided for irradiation, where an arrangement of the lattice and the diamond layer is partially permeable for primary radiation and/or secondary radiation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a lighting device comprising an electromagnetic primary radiation emitting radiation source. USE - Wavelength converter i.e. wavelength converter foil, for use in a lighting device (all claimed). Uses include but are not limited to a vehicle headlight, a projector, an optical lithography system and an endoscope. ADVANTAGE - The wavelength converter contains a polymer such as silicone, polyurethane or epoxy which possesses high transparency, where the polymer is thermal mechanically adaptable and flexibly processable, thus ensuring high conversion efficiency even for higher radiation efficiency and/or low transmission losses
