1. A light emitting diode (LED) package, comprising:

  • at least one LED that emits LED light in an LED emission profile;

    a first plurality of scattering particles to scatter a first target wavelength and a second plurality of scattering particles to scatter a second target wavelength different from said first target wavelength, said first and second scattering particles arranged around said LED to scatter said LED light to improve the uniformity of said LED emission profile; and

    wherein said first and second scattering particles are arranged in regions around said LED based on emission angles.
