摘要：
A light emitting device comprises at least one light emitter, typically an LED, operable to generate blue light and a wavelength conversion component. The wavelength conversion component can be light transmissive or light reflective and comprises at least two phosphor materials that are operable to absorb at least a portion of said blue light and emit light of different colors and wherein the emission product of the device comprises the combined light generated by the LED(s) and the phosphor materials. The phosphor materials are configured as a pattern of non-overlapping areas on a surface of the component.
