Abstract

PURPOSE:To eliminate any beam deterioration as well as to improve the efficiency by sealing a specific gas under a specific pressure range in a bulb of a discharge lamp. CONSTITUTION:A transparent tube is formed with its inside diameter of 16-38mm., and electrodes are provided on both ends of the transparent tube to form a bulb for a discharge lamp. Only one rare gas selected from Xe, Kr, Ar, Ne, and He, is sealed in the bulb of discharge lamp, where the pressure of the rare gas is in the ranges 0.5torr>Xe>0.05torr, 0.8torr>Kr>0.1torr, 1.0torr>Ar>0.2torr, 4.0torr>Ne> 0.5torr, and 4.0torr>He>0.8torr.
