摘要:
A method of applying a phosphor coating is described. The method comprises forming a suspension of a phosphor and a polymer binder dissolved in a solvent, the phosphor comprising at least one of a nitridosilicate or an oxonitridosilicate phosphor, the polymer binder being capable of decomposing thermally; applying the suspension to a substrate to form a coating; drying the coating; and baking the coating in an inert atmosphere to thermally decompose the polymer binder to form the phosphor coating, preferably at a temperature less than about 400° C. in a nitrogen atmosphere. A preferred polymer binder is polyisobutyl methacrylate

A wavelength-converting plate for a wavelength-converted light emitting diode (LED) assembly. The wavelength-converting plate includes microlenses deposited thereon. The microlenses may have an index of refraction different from the index of refraction of the wavelength-converting plate. The microlenses on the top surface of the plate increase lumen output in a direction normal to the top surface of a wavelength-converting plate.
