PHOTOLUMINESCENCE WAVELENGTH CONVERSION COMPONENTS FOR SOLID-STATE LIGHT EMITTING DEVICES AND LAMPS

摘要

A wavelength conversion component for a light emitting device comprises at least one photoluminescence material; and a light scattering material. 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. Use of a light scattering material can reduce usage of the photoluminescence material and can improve an OFF state appearance of the component.
