    Abstract: An arc lamp having short length. The lamp includes an anode extending into one end of the lamp envelope and a cathode extending into the other end of the envelope. Both electrodes include a shoulder portion outside of the envelope in abutting relation with the ends of the envelope. The ends of the envelope are metallized on the outer surface thereof and a sealing ring includes an annular portion enclosing the ends of the envelope for sealing relation with the metallized bands on the envelope. The ring further includes a radially inwardly extending seat portion disposed intermediate the ends of the envelope and the shoulder portion of the electrodes.

    Abstract: An arc lamp having a tubular envelope enclosing a first fixed electrode disposed at one end and a second electrode structure, having a movable tip, disposed at the other end of the tubular envelope. The second electrode structure includes a fixed hollow electrode portion secured to the tubular housing and a movable electrode portion slidably carried in the opening of the hollow electrode and provided with a tip portion for extending out of the hollow electrode. The movable electrode includes a core of magnetic material having a tip extending therefrom through an opening in the hollow electrode and in axial alignment with the first electrode. The core is in biased relation with the hollow electrode by means of a spring seated between the hollow electrode and core. An electromagnetic coil is circumferentially mounted about the core for movement of the movable electrode responsive to energization of the coil.
