摘要： A low-pressure discharge lamp includes, in an exemplary embodiment, a light-transmissive envelope, a fill-gas composition capable of sustaining a discharge sealed inside the light-transmissive envelope, and a phosphor composition at least partially disposed on an interior surface of the light-transmissive envelope. The phosphor composition is disposed on an interior surface of the light-transmissive envelope in a plurality of layers that include at least a basecoat phosphor layer and a topcoat phosphor layer. The basecoat phosphor layer includes at least one halophosphor and the topcoat phosphor layer includes a blend of at least two rare earth phosphors. The basecoat phosphor layer has a greater Color Rendering Index (CRI) value than the topcoat phosphor layer.

摘要： Disclosed herein are lamps comprising a radiation source and a phosphor blend configured for conversion of radia tion, the phosphor blend including at least two different rare earth phosphors, wherein the phosphor blend comprises at least one multimodal rare earth phosphor. Disclosed advantages may include greater lumen output than an identical lamp in which the phosphor blend, at the same loading, does not comprise at least one multimodal rare earth phosphor.
