Abstract: A multi-stage lamination process is used to laminate a wavelength conversion film (220) to a transparent substrate (230), and subsequently to a light emitting element (110). The wavelength conversion film (220) may be an uncured phosphor-embedded silicone polymer, and the lamination process includes heating the polymer so that it adheres to the transparent substrate (230), but is not fully cured. The phosphor-laminated transparent substrate (230) is sliced/diced and the wavelength conversion film (220) of each diced substrate is placed upon each light emitting element (110). The semi-cured wavelength conversion film (220) is then laminated to the light emitting element (110) via heating, consequently curing the phosphor film. Throughout the process, no glue is used, and the optical losses associated with glue material are not introduced.
