  • Method, composition, and means for limiting lead wire arcing in an arc discharge lamp
    Patent number: 5449971
    Abstract: A material is provided on the lead wires that support a filament of a fluorescent lamp assembly to inhibit arcing associated with filament burnout. The material comprises a glass that is non-alkaline. Another preferred arrangement is to incorporate a material into the assembly that will release an arc inhibiting gas in response to arcing of the lead wires. For example, a calcium carbonate or strontium carbonate material releases carbon dioxide to terminate undesired lead wire arcing.
