  • Aluminum base for electric lamps having a plastic coating for improved corrosion resistance
    Patent number: 4178059
    Abstract: A screw base for high intensity discharge lamps or for larger sizes of incandescent lamps utilizes a threaded aluminum shell coated with a thin film of polytetrafluoroethylene. The thin film is penetrated at points of maximum contact pressure with the socket to provide electrical continuity while effecting a low friction surface preventing galling and sticking of the base in the socket and permitting easy lamp insertion and removal.
    Type: Grant

  • Ceramic lamp having tubular inlead containing yttrium-zirconium mixture
    Patent number: 4056752
    Abstract: A high pressure sodium vapor lamp arc tube of alumina ceramic has end closures one of which includes an externally projecting tube of niobium or tantalum serving as inlead and having a portion extending into the inside of the arc tube. A tungsten electrode shank is welded into the end of the niobium tube but the seal at the weld may not be fully hermetic. To assure a fully hermetic seal, a mixture of yttrium and zirconium which has a lower melting point than pure yttrium is included in the niobium tube.

  • Universal burning alkali metal vapor lamp with amalgam storage in exhaust tubulation
    Patent number: 4035682
    Abstract: In a high pressure alkali metal vapor lamp arc tube having a sealed off metal exhaust tube projecting through an end closure, the tip of the exhaust tube is the cold spot where excess alkali metal condenses. A fine mesh screen friction-retained in the exhaust tube prevents passage of liquid droplets; any alkali metal impinging on the screen is slowly revaporized and condenses at the tip due to the higher temperature at the screen.
