ABSTRACT:
The cathode for a gas discharged lamp includes gettering materials which are placed within the interior of the cathode shell. Other components may also be placed inside the cathode for continuous activation. For example, in mercury vapor lamps, a mercury amalgam is placed within the cathode. In another embodiment, a mass of electron emission assisting compound is placed within the cathode to replenish the emission assisting compound which deteriorates from the cathode.
