  • Controlled arc stream in high intensity discharge lamps
    Patent number: 4064418
    Abstract: A discharge lamp with minimized upward bowing of the arc in which conductors carrying full arc current are placed in close proximity above and below the arc tube. The conductors run parallel with the longitudinal axis of the arc tube and the conductors above the arc are electrically connected in such a manner as to carry full lamp current in the opposite direction of the arc, thus repelling the arc in a downward direction, and the conductor or conductors below the arc tube are electrically connected so as to carry full lamp current in the same direction of the arc, thus attracting the arc downward.
