  • Patent number: 8133433
    Abstract: The disclosure relates to fluorescent lamps and methods of manufacture wherein the mercury is dosed into the lamp in a solid material containing mercury, bismuth, indium and another metal. In one embodiment, the metal is selected from the group consisting of zinc, tin, lead, silver, gold, copper, gallium, titanium, nickel, and manganese. Preferably, the atomic ratio of the indium to the bismuth is in the range of about 0.4:0.6 to 0.7:0.3. The atomic ratio of zinc to the combination indium and bismuth may preferably be in the range of about 0.01:0.99 to 0.20:0.80, and the atomic ratio of mercury to the combination of the indium, bismuth and zinc is preferably in the range of about 0.01:0.99 and 0.15:0.85.

  • Publication number: 20110250455
    Abstract: Mechanical plating provides a new technique of manufacturing of certain materials containing multiple elements, including amalgams, and novel pellets containing multiple materials. Some embodiments provide new and versatile materials for dosing mercury, metals or other inorganic compounds into lamps. Some embodiments include materials comprising layers of metals or compounds built up on a substrate. One embodiment is a layer of zinc amalgam applied to a glass sphere. Also disclosed is an improved method of manufacture for such particles that will speed production, increase yields, lower costs and reduce exposure to mercury in the workplace.

  • Patent number: 6815888
    Abstract: A pelletized lamp fill material suitable for delivering a precise quantity of rhenium and a halogen into the light emitting chamber of a tungsten halogen lamp. The pellet is formed by pressure aggregating a mixture of a metal powder and a rhenium-halogen compound. In a pellet suitable for delivering bromine into the lamp, the metal powder may be mixed with rhenium tribromide powder to form the pellet. The release of the bromine and rhenium is desirably controlled over time as a function of temperature.
