Abstract
Official abstract text for this publication.
The invention provides a light-emitting arrangement comprising: a light source adapted to emit light of a first wavelength; a wavelength converting member comprising an organic wavelength converting material adapted to receive light of said first wavelength and to convert at least part of the received light to light of a second wavelength, said wavelength converting member and said light source being mutually spaced apart; and a sealing structure at least partially surrounding said wavelength converting member to form a sealed cavity containing at least said wavelength converting member, the gas pressure within said sealed cavity being 1*10 −5 bar (1 Pa) or less. At such pressure, the organic phosphor has been found to have particularly good stability, thus resulting in a longer life time of the phosphor.
First claim
Opening claim text (preview).
The invention claimed is: 1. A light-emitting arrangement, comprising: a light source adapted to emit light of a first wavelength, and a wavelength converting member comprising an organic wavelength converting material adapted to receive light of said first wavelength and to convert at least part of the received light to light of a second wavelength, wherein the wavelength converting member comprises a polymeric matrix or carrier for the organic wavelength converting material, s…
