Patent ID: 8124996

Claim:
A light emitting device comprising: a substrate member comprising a surface region; one or more light emitting diode devices overlying the surface region, at least one of the light emitting diode devices being fabricated on a semipolar or nonpolar GaN containing substrate, the at least one or more light emitting diode devices fabricated on the semipolar or nonpolar GaN containing substrate emitting substantially polarized emission of one or more first wavelengths; an optically transparent member coupled to the one or more light emitting diode devices; an optical path provided between the one or more light emitting diode devices and the optically transparent member; a thickness of one or more entities formed within a vicinity of the optically transparent member, one or more of the entities being excited by the substantially polarized emission to emit electromagnetic radiation at one or more second wavelengths; wherein the one or more light emitting diode device include a blue LED device capable of emitting electromagnetic radiation from about 430 nanometers to about 490 nanometers and the one or more entities is capable of emitting substantially yellow light, the substantially polarized emission being blue light; and wherein the one or more entities comprises a phosphor or phosphor blend selected from at least one of (Y,Gd,Tb,Sc,Lu,La) 3 (Al,Ga,In) 5 O 12 :Ce 3+ , SrGa 2 S 4 :Eu 2+ , SrS:Eu 2+ , and colloidal quantum dot thin films comprising CdTe, ZnS, ZnSe, ZnTe, CdSe, or CdTe.
