    Abstract: The voltage required to initiate an arc across the electrode gap in a gas-filled arc lamp can be significantly reduced by providing a refractory metal sleeve overhanging the tapered end of one of the electrodes. The direction and extent of the overhang must be such that the electric field strength at the distal end of the overhanging portion of the sleeve is greater than at the apex of the electrode to which the sleeve is affixed.

    Abstract translation: 通过提供悬垂在一个电极的锥形末端的难熔金属套筒,可以显着地减少在充满气体的电弧灯中跨越电极间隙引发电弧所需的电压。 突出端的方向和范围必须使得套筒的悬垂部分的远端处的电场强度大于在套筒固定的电极的顶点处的电场强度。
