Selective filtering of wavelength-converted semiconductor light emitting devices

摘要

A light emitting device comprises a filter material capable of absorbing the first light and overlying the wavelength-converting material. A light emitting device comprises: (a) a semiconductor light emitting device chip capable of emitting first light having a first wavelength; (b) a wavelength converting material (20) capable of absorbing the first light and emitting second light having a second wavelength, where the wavelength converting material overlies at least a portion of the top surface and a portion of the side surface of the chip; and (c) a filter material (19) capable of absorbing the first light and overlying the wavelength converting material.
