Patent ID: 7906892

Claim:
A light emitting device, comprising: a first light emitting diode disposed on a substrate, the first light emitting diode to emit light of a first wavelength; a wavelength conversion material enclosing the first light emitting diode and containing a phosphor for performing wavelength conversion of a portion of the light of the first wavelength emitted from the first light emitting diode; a second light emitting diode separated from the first light emitting diode and disposed on the substrate, the second light emitting diode to emit light of a second wavelength longer than the first wavelength; and a dielectric multilayer reflection mirror formed on the wavelength conversion material and including at least one pair of dielectric layers, wherein the layers of the at least one pair of dielectric layers do not have the same refractive index, wherein the at least one pair of dielectric layers reflect the light of the second wavelength incident on the wavelength conversion material, and wherein the dielectric multilayer reflection mirror is disposed on a portion only of an upper surface of the wavelength conversion material.
