Abstract

PURPOSE:To save the electric power consumption, increase the staring voltage at a low temperature region, and control the flickering during starting at a low temperature by using a tube with specific tube diameter, ring diameter, sealed gase, and gas pressure thereof. CONSTITUTION:The diameter (d) of a tube is specified at 30-32mm., and the outer diameter (D) of a ring at 220-240mm.. A rare gas mixture of xenon-argon, xenon- neon, or xenon-argon-neon which contains xenon at least not more than 25% is sealed as a sealed gas, and the sealed pressure is specified at 1.3-2.5torr.
