  • Excimer lamp
    Patent number: 9159545
    Abstract: A first excimer lamp includes: a quartz glass-made light-emitting tube containing an excimer emission gas sealed therein; and a pair of electrodes for generating dielectric barrier discharge. One of the pair of electrodes is disposed in the inner space of the light-emitting tube so as to extend in the direction of a tube axis of the light-emitting tube, and the other one of the pair of electrodes is embedded in the tube wall of the light-emitting tube so as to extend in the direction of the tube axis of the light-emitting tube. The one electrode is electrically connected to a conductive foil hermetically embedded in an end portion of the light-emitting tube.
    Type: Grant
