Abstract:
1. A wavelength conversion component for a light emitting device comprising: at least one photoluminescence material; and a light scattering material, wherein the light scattering material has an average particle size that is selected such that the light scattering material will scatter excitation light from a radiation source relatively more than the light scattering material will scatter light generated by the at least one photoluminescence material, wherein the wavelength conversion component is configured such that in operation a portion of the excitation light comprising blue light having a wavelength of greater than or equal to 440 nm is emitted through the wavelength conversion component to contribute to a final visible emission product; wherein the light scattering material scatters the blue light at least twice as much as light generated by the at least one photoluminescence material.
