Abstract:
A wavelength conversion structure comprises a first phosphor layer and a second phosphor layer formed on the first phosphor layer, wherein the first phosphor layer comprises a plurality of first phosphor particles, and the second phosphor layer comprises a plurality of second phosphor particles. The average particle size of the second phosphor particles is not equal to that of the first phosphor particles.
