Abstract

PURPOSE:To eliminate a rise of the starting voltage at a low temperature and the generation of the flicker, and thereby to enhance the luminous efficiency of a circular fluorescent lamp, by forming the size of a circular glass bulb in a certain diameter of the tube, and by introducing ino the tube a mixed rare gas whose principal component is argon and the by sealing the tube under a certain sealing pressure. CONSTITUTION:The outer diameter d of the tube of a circular glass bulb is formed in the length of 30-32mm. and the mixed rare gas whose principal component are mercury and argon, or argon is introduced into the tube, then sealed under a sealing pressure of 1.5-2.5 torr. Thereby, this luminous efficiency is enhanced as compared with that of a conventional circular fluorescent lamp, and further, the rise of starting voltage at a low temperature and the generation of the flicker resulting from a conventional electric power-saving type circular fluorescent lamp can be eliminated.
