    Abstract: A method for fabricating an LED/phosphor structure is described where an array of blue light emitting diode (LED) dies are mounted on a submount wafer. A phosphor powder is mixed with an organic polymer binder, such as an acrylate or nitrocellulose. The liquid or paste mixture is then deposited over the LED dies or other substrate as a substantially uniform layer. The organic binder is then removed by being burned away in air, or being subject to an O2 plasma process, or dissolved, leaving a porous layer of phosphor grains sintered together. The porous phosphor layer is impregnated with a sol-gel (e.g., a sol-gel of TEOS or MTMS) or liquid glass (e.g., sodium silicate or potassium silicate), also known as water glass, which saturates the porous structure. The structure is then heated to cure the inorganic glass binder, leaving a robust glass binder that resists yellowing, among other desirable properties.

    Abstract: A ceramic green wavelength conversion element (120) is coated with a red wavelength conversion material (330) and placed above a blue light emitting element (110) such that the ceramic element (120) is attached to the light emitting element (110), thereby providing an efficient thermal coupling from the red and green converters (330, 120) to the light emitting element (110) and its associated heat sink. To protect the red converter coating (330) from the effects of subsequent processes, a sacrificial clear coating (340) is created above the red converter element (330). This clear coating (340) may be provided as a discrete layer of clear material, or it may be produced by allowing the red converters to settle to the bottom of its suspension material, thereby forming a converter-free upper layer that can be subjected to the subsequent fabrication processes.

    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.
