    • 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.
    • 灯壳在氧化铝层上设置有氧化铝层和多层荧光体涂层。 荧光体涂层包括具有第一重量百分比的稀土活化剂的顶部荧光体层和具有第二重量百分比稀土活化剂的中间荧光体层。 第二重量百分数小于第一重量百分比,使得涂层中的活化剂的总量减少,同时保持所需的灯亮度和显色指数(CRI)。 优选地,第二重量百分比为第一重量百分比的约50-60%,中间层为涂层总重量的约30-50%,使得涂层中活化剂的总重量不大于约 如果第一和第二重量百分比相同,涂层中活化剂重量的80%。
