Abstract
PURPOSE: To stabilize arc and prevent the arc from coming into contact with the inside surface of luminous tube, by specifying the lamp voltage and the pressure of filled argon.
CONSTITUTION: Electrodes 2, 2 are provided at the ends of the luminous tube 1. The distance between these electrodes is not less than 800 mm. The inner diameter of the luminous tube 1 is not more than 50mm. Mercury and, if necessary, metal halide are filled as luminescent substances in the luminous tube 1. Argon is filled as starting gas in the tube. The pressure P torr of the argon filled in the luminous tube and the lamp voltage V are set as PV<1.9×104 and P>4 torr
