COLOR-STABLE PHOSPHOR CONVERTED LED

摘要

A light-emitting device is provided, comprising at least one light-emitting diode (100) for emitting light of a first color and a luminescent material (102) arranged on said at least one light-emitting diode to receive at least part of the light emitted by said light-emitting diode. The light-emitting device further comprises a filter (103) arranged to receive light emitted by said light-emitting diode (100) and transmitted through said luminescent material (102) and to absorb light of said first color. The filter comprises a pigment compound distributed in a matrix of silicon and oxygen atoms, in which matrix at least a portion of said silicon atoms are directly bonded to hydrocarbon groups.
