A light emitting device comprises at least one solid-state light source (LED) operable to generate excitation light and a wavelength conversion component located remotely to the at least one source and operable to convert at least a portion of the excitation light to light of a different wavelength. The wavelength conversion component comprises a light transmissive substrate having a wavelength conversion layer comprising particles of at least one photoluminescence material and a light diffusing layer comprising particles of a light diffractive material. This approach of using the light diffusing layer in combination with the wavelength conversion layer solves the problem of variations or non-uniformities in the color of emitted light with emission angle. In addition, the color appearance of the lighting apparatus in its OFF state can be improved by implementing the light diffusing layer in combination with the wavelength conversion layer. Moreover, significant reductions can be achieved in the amount phosphor materials required to implement phosphor-based LED devices.
