Abstract
A sealing electrode for discharge lamp having electrically conductive cup, and an emitter pellet is disclosed. The cup seals a passage into the discharge lamp, and additionally supports the electrode pellet or tip for the discharge. The design enables the emitter, electrode and seal structure to be made separately off line, while also enabling the emitter to be protected from contaminants during subsequent assembly.
