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.
