Abstract

PURPOSE:To save the electric power consumption the control and flickering by using a tube in which the diameter of the tube, and ring, sealed gase, and sealed gas pressure thereof are of specific ones. CONSTITUTION:The diameterd 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-krypton-argon, xenon-krypton-neon, or xenon-krypton-argon-neon in which xenon and krypton contained ar at least not more than 30% is sealed as a sealed gas, and the gas pressure is specified at 1.4-2.7torr.
