Abstract

The invention provides a light-emitting arrangement (100, 200, 300), comprising: a light source (101, 201, 301) adapted to emit light of a first wavelength; a wavelength converting member (106, 206, 306) comprising a 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; a sealing structure (103) at least partially surrounding said wavelength converting member to form a sealed cavity (105, 205, 305) containing at least said wavelength converting member, said cavity containing a controlled atmosphere; and a getter material (108, 208, 308) arranged within said sealed cavity,wherein said getter material is adapted to operate in the presence of water and/or produces water as a reaction product. Such getter materials have high capacity for removal of oxygen from the atmosphere within the sealed cavity,such that a low oxygen concentration can be maintained within the cavity. Hence, the lifetime of the wavelength converting material may be prolonged.
