Abstract

PURPOSE:To set an exact amount of the enclosed mercury so as to stabilize a discharge, by forming a contracted area of smaller diameter on the inside walls of both ends of an arc-shaped glass tube and enclosing mercury in the space toward the end from the contracted areas. CONSTITUTION:A discharge portion 1a is provided by forming about 130 deg. range of a quartz made glass tube 1 into a circular arc shape, and electrode portions 1b are formed on its both ends. Furthermore, a contracted portion 1c projecting to the circumferential direaction is formed on the predetermined position of the inside wall of each electrode portion 1b, mercury 3 is enclosed in a section toward each end of the tube 1 from each contracted portion 1c, and an electrode 2 is provided, while allowing it to project by 0.7-1.0mm. into the inside of the tube from each surface of mercury 3. Then, plasma arc is generated to carry on discharge, by applying an electric field of 20-100V/mm. potential gradient to the space between electrodes 2, 2. Thereby, the quantity of enclosed mercury 3 can be set exactly by the contracted portions 1c, and the lamp current can be stabilized during a discharge.
