  • Fluorescent lamp of improved lumen maintenance and mercury consumption
    Patent number: 8629608
    Abstract: The inner surfaces of fluorescent lamp tubing are provided with a phosphor coating. The phosphor coating defines an inward-facing surface. A protective coating is deposited on the inward-facing surface of the phosphor coating. The protective coating defines an innermost surface and makes effective recombination of Hg ions possible on the innermost surface of the second coating before the Hg ions collide with the phosphor particles in the phosphor coating.
    Type: Grant
