ABSTRACT:
An electric discharge lamp with an internally threaded electrode is disclosed. The lamp includes an envelope, a support rod, and an electrode can with an interior surface having a multiplicity of peaks, points, of sharp edge regions. These equal height prominences evenly extended around the inside wall of the electrode can. The threaded electrode yields a highly emissive electrode with no emissive material to be eroded.
