Abstract
PURPOSE: To provide a high voltage vapor discharge lamp which lowers its firing start voltage, reduces irregularity and stabilizes its quality by regulating the interval between the central shaft and supporting wire of a transparent ceramic light emitting tube.
CONSTITUTION: Electrodes 2a, 2b are sealed via metallic caps 3a, 3b, respectively of niobium or the like at both ends of a light emitting tube 1 of transparent ceramic filled with sodium, mercury and inert gas to support the electrodes 2a, 2b by the caps 3a, 3b. There are disposed the central shaft of the tube 1 and a supporting wire 4 connected to the metallic cap 3a so that the interval therebetween is within 11mm. Thus, it can sufficiently recuce the firing start voltage. It can also simplify the construction adapted for mass production.
