Abstract
PURPOSE: To stabilize arc without fail, by specifying the relation among the lamp voltage, the pressure of filled starting gas and the mixture ratio of xenon or krypton to argon.
CONSTITUTION: Electrodes 2, 2 are provided at the ends of a luminous tube 1. The distance between these electrodes is not less than 800mm. The input per unit length of the electrodes is not less than 60W/cm. The inner diameter of the luminous tube 1 is not more than 50mm. The pressure P torr of starting gas filled in the luminous tube 1, the lamp voltage V and the mixture ratio R % of xenon or krypton to argon are related to one another as PV≤190R+19000
