  • Patent number: 8324793
    Abstract: A luminescent material includes an aluminate phosphor of formula I A1+xMg1+yAl10+zO17+x+y+1.5z:Eu2+, R3+, where 0?x?0.4, 0?y?1 and 0?z?0.2. A is selected from Ca, Ba, and Sr and combinations thereof. The aluminate phosphor is doped with a rare earth ion (R3+), which exists in stable multi-valence states in the luminescent material. R3+ is selected from the group consisting of Sm3+, Yb3+, Tm3+, Ce3+, Tb3+, Pr3+ and combinations thereof. Phosphors of formula I may be blended with other blue, yellow, orange, green, and red phosphors to yield white light phosphor blends. A lighting apparatus including such a luminescent material is also presented. The light apparatus includes a light source in addition to the luminescent material.

  • Patent number: 7737639
    Abstract: A fluorescent lamp includes a light-transmissive glass envelope having an inner surface, means for providing an electric discharge to the interior of the glass envelope, a phosphor layer within the interior of the glass envelope and a discharge-sustaining fill gas and a mercury dose sealed inside the light-transmissive glass envelope. The light-transmissive glass envelope can comprise a light-transmissive mixed alkali glass envelope and the phosphor layer can comprise a phosphor layer of approximately three mg/cm2. A barrier layer of approximately 0.3 mg/cm2 or less of alumina can be applied to the inner surface of the light-transmissive glass envelope. The mercury dose can be present in an amount to provide a saturated mercury vapor pressure within the light-transmissive glass envelope throughout substantially the entire life of the lamp. The lamp can have an end-of-life mercury consumption value of approximately 0.63 mg or less, including 0.
