A light emitting device includes at least one particle over the light emitter. Light at a first wavelength travels from the emitter along a first path adjacent to the particle and at a second wavelength along a second path that passes through the particle. The particle converts the light on the second path from the first wavelength into a second wavelength. The light at the first wavelength mixes with the light at the second wavelength to form light of a third wavelength, which may be white light or another color.
