Abstract
A glow discharge lamp includes a light-transmitting envelope containing a noble gas fill material. An anode electrode and a cathode electrode are spacedly located within the envelope. The anode electrode includes a single wire having a convoluted portion adjacent the cathode electrode and lying in a plane parallel to a plane intersecting the cathode electrode and a pair of lead-in wires supporting the cathode electrode. The improved anode construction results in an increase in both light output and lamp efficacy.
