Abstract:
A conformal thin-film phosphor layer is disposed over a surface of a hemispherical lens, a Fresnel lens, or a microlens array, thereby forming a phosphor-coated light extraction structure. Also disclosed is a phosphor-converted photonic crystal light emitting device that incorporates a thin-film phosphor layer. A wafer-level packaging process incorporating a thin-film phosphor layer is also disclosed herein.
