摘要： A lamp envelope is provided with an alumina layer and a multilayer phosphor coating on the alumina layer. The phosphor coating includes a top phosphor layer with a first weight percent of rare earth activators and a middle phosphor layer with a second weight percent of rare earth activators. The second weight percent is less than the first weight percent so that a total amount of the activators in the coating is reduced while maintaining a required lamp brightness and color rendering index (CRI). Preferably, the second weight percent is about 50-60% of the first weight percent and the middle layer is about 30-50% of a total weight of the coating so that a total weight of the activators in the coating is no more than about 80% of a weight of the activators in the coating if the first and second weight percents were the same.

摘要： An electroluminescent lamp having a high color rendering index (CRI) can be made using a phosphor blend comprising a mixture of an electroluminescent phosphor and an europium-activated alkaline earth silicon nitride phosphor, wherein the electroluminescent phosphor is selected from a blue-emitting electroluminescent phosphor, a blue-green-emitting electroluminescent phosphor, or a combination thereof. Preferably, the lamp exhibits a CRI of at least about 75, and, more preferably, at least about 80. A preferred blend contains from about 10% to about 20% by weight of the europium-activated alkaline earth silicon nitride phosphor.
