Abstract: A fluorescent lamp includes a glass envelope that is light transmitting. There is means for providing a discharge inside the en velope. A discharge-sustaining fill of mercury and an inert gas is sealed inside the envelope. An underlying phosphor-containing layer is disposed inside the envelope. The underlying layer includes yttrium vanadate phosphor. A protective phosphor-containing layer is disposed over the underlying layer at a location that is more distal from the glass than the underlying layer.

Abstract: 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.

Abstract: A fluorescent lamp is provided including a phosphor blend comprising less than about 10% by weight rare earth phosphor, based on the total weight of the phosphor composition. This phosphor blend, when coated on a lamp, provides a lamp that exhibits high color rendering index (CRI), of at least 87, while simultaneously achieving low CCT. of less than about 4500K, i.e. of between about 3000K and 4500K. The phosphor system provided includes a non-rare earth strontium red broad band phosphor, a non-rare earth blue broad band halophosphor, and a rare earth-doped green-blue emitting phosphor, more specifically, a combination of SAR and blue-halo non-rare earth phosphors, and less than 20wt% BAMn phosphor, based on the total weight of the phosphor system.

Abstract: A fluorescent lamp comprises a glass envelope that is light transmitting. Also included is means for providing a discharge inside the envelope. A discharge-sustaining fill includes mercury and an inert gas sealed inside the envelope. An underlying phosphor- containing layer is disposed inside the envelope. The underlying layer includes zinc silicate phosphor. A protective phosphor-containing layer is disposed over the underlying layer at a location that is more distal from the glass than the underlying layer. A ratio of a surface density of the protective layer to a surface density of the underlying layer is at least 0.4: 1.
