PROBLEM TO BE SOLVED: To provide a method for forming a thin-film phosphor layer of a substantially uniform thickness on an optical path of an LED.SOLUTION: There is provided an improved deposition method involving: (1) forming a phosphor powder layer that is substantially uniformly deposited on a substrate surface; and (2) forming a polymer binder layer to fill gaps among loosely packed phosphor particles, thereby forming a substantially continuous layer of thin film. A parylene-based polymer is suitably used as the polymer binder. By this method, a thin-film phosphor layer can be formed. |
