ABSTRACT:
A negative glow discharge lamp including a wire anode and a cathode disposed within a phosphor-coated envelope. The thickness radius of the wire used for the anode is less than the electron mean free path in the discharge. In a preferred embodiment, the wire anode is in the form of a cylindrical cage coaxially surrounding the cathode and includes a pair of wire rings spaced apart and interconnected by a plurality of transversing wire segments. The diameter of each of the wire rings and the length of each of the wire segments are greater than the electron mean free path in the discharge. The wire anode does not attain a positive anode voltage drop (PAVD) during lamp operation. As a result, the efficiency of the glow discharge lamp is improved.
