  • Patent number: 9870913
    Abstract: A flash discharge tube includes tungsten pins configuring a pair of discharge electrodes, and an envelope. The envelope includes a central region, serving as an alkali-free region, which is configured with an alkali-free glass except for quartz glass. The central region becomes in a high temperature state during a firing operation of the flash discharge tube. The central region is smaller than a maximum region enclosing a gas-tight space formed by hermetically sealing the pair of the discharge electrodes and is not smaller than a minimum region enclosing an arc-discharge space formed between the tungsten pins of the pair of the discharge electrodes. The alkali-free region contains either no alkali metal component or not larger than a predetermined amount of an alkali metal component. Then, a trigger electrode is disposed in the alkali-free region. This provides the flash discharge tube featuring a stable short-interval continuous-firing operation.

  • Patent number: 7982400
    Abstract: A high-intensity discharge lamp includes a discharge vessel made of an insulator, and a cathode and anode. A V-shaped gap is provided between the anode and a first region of the vessel directly adjacent to where the anode separates from an interior surface of the vessel. A secondary cathode is provided on an exterior surface of the vessel at the first region, where the secondary cathode is positioned so that the V-shaped gap and the first region are between the secondary cathode and the anode. An electric field at the first region produces a dielectric barrier discharge (DBD) which generates ultraviolet (UV) and vacuum ultraviolet VUV photons that impinge on the cathode and initiate a breakdown between the cathode and anode.
