Abstract (en)
[origin: WO2009135345A1] A compound HID electric arc tube includes a discharge tube and two lead-out tubes. The discharge tube has an envelope of blown melted quartz glass or Vycor-type quartz glass with a semitranslucent polycrystalline aluminum oxide (PCA) layer applied to the inside surface thus forming a double-layer envelope. The lead-out tubes are made of melted quartz glass or Vycor-type quartz glass and, near the two ends of the arc tube, are partially coated on their inside surfaces with a polycrystalline aluminum oxide (PCA) layer. After high temperature sintering of the electric arc tube, a two-stage method is used to seal the electrodes. A glass solder seal is used in the first section of the lead-out tube having the inner coating of PCA, and a molybdenum foil press seal is used to seal the quartz glass second section.
