    Abstract: A negative glow discharge lamp including an anode and an indirectly-heated cathode disposed within a phosphor-coated envelope. The cathode includes a heater filament surrounded by a metallic cylinder which is coated with an emissive material. The differential resistance of the heater filament is sufficient to internally ballast the flow discharge lamp.

    Abstract: A glow discharge lamp having increased efficiency and including a light-transmitting envelope which contains a gas fill material. A pair of electrodes is disposed in the envelope. Lead-in wires couple to the electrodes and are hermetically sealed in the envelope. The gas fill material includes at least one noble gas and a quantity of nitrogen. The nitrogen is in an amount from 1.5 percent to less than 10 percent of the total fill material.

    Abstract: A glow lamp includes electrodes having both elements and oxides formed with a portion of the elements applied thereto to provide a glow lamp which can be used as a switch and which has a relatively low breakdown voltage but a relatively large current-handling capability. The glow lamp is constructed by a method which includes the step of causing relatively large, variable frequency currents to flow between adjacent electrodes for a limited time period to create the combination of elements and oxides on the electrodes.
