<p>A xenon short-arc lamp includes an arc tube containing a first electrode and a second electrode, sealing tubes on both edges of the arc tube and supporting tubes that are supported in the sealing tubes. Core rods of the first electrode and the second electrode are inserted through and supported by the supporting tubes. A high alternating voltage is applied at the start of the lighting. A trigger wire that is electrically connected to the first electrode is wound around an outer surface of the second electrode side sealing tube at an arc tube side position other than a location of the sealing tube that faces the metal foil. The trigger wire may be wound around an rising part of the arc tube.</p> |
