Abstract: Coating systems suitable for use in fluorescent lamps, particularly as scattering agents within a UV-reflecting coating for the purpose of improving fluorescent lamp luminosity. Such a coating system is provided on a transparent or translucent substrate and includes a phosphor coating and a scattering agent that scatters UV rays. The scattering agent includes an inorganic powder present in a separate UV-reflecting layer adjacent the phosphor coating and/or dispersed in the phosphor coating so that the scattered UV rays are absorbed by the phosphor coating and cause the phosphor coating to emit visible light. The inorganic powder exhibits low or no absorption to UV rays having wavelengths of 185 nm and 254 nm and is not reactive with mercury.

Abstract: Phosphor-containing coating compositions and methods capable of changing the lumen maintenance characteristics of phosphor-containing coatings and fluorescent lamps that utilize such coatings. Lumen maintenance of a fluorescent lamp can be modified by forming a phosphor-containing coating to contain at least a first phosphor that depreciates during operation of the fluorescent lamp, and forming the phosphor-containing coating to further contain an additive composition in a sufficient amount and sufficiently uniformly distributed in the phosphor-containing coating to inhibit depreciation of the first phosphor during operation of the fluorescent lamp.

Abstract: Described are methods and apparatus for providing fluorescent lamps having a two-layer phosphor coating that includes a base coating and a top coating that economically provides a high color rendering index (CRI) of at least 87 with improved brightness. In an embodiment, a low-pressure discharge lamp includes a light transmissive envelope having a basecoat phosphor layer disposed on an inner surface, wherein the basecoat phosphor layer includes less than ten percent weight of a rare earth phosphor. Also included is a topcoat phosphor layer on a surface of the base coat phosphor layer that includes a blend of at least red, green, green-blue and blue emitting rare earth phosphors, and a fill gas composition within the light transmissive envelope.

Abstract: Phosphor particles, methods for their use to produce fluorescent lamps, and fluorescent lamps that make use of such particles. Such a phosphor particle has a core surrounded by a shell, and the shell contains GdMgB5O10 doped (activated) with at least terbium ions as a rare earth-containing phosphor composition that absorbs ultraviolet photons to emit green-spectrum light. The core is formed of a mineral material that is chemically compatible with the rare earth-containing phosphor composition of the shell, but does not contain intentional additions of terbium.
