Abstract

PURPOSE:To achieve excellent power save effect having improved start characteristic and tube characteristic by encapsulating specific amount of rare gases having the atomic weight higher and lower than that of Ar and the remainder of Ar mixed gas under specific pressure into a bulb. CONSTITUTION:Since the tube current is increased when the outer-diameter of tube exceeds over 30mm. and the size of the ballast is increased for conventional standard while the light is decreased for same tube current when the outer-diameter is shorter than 26mm., the outer-diameter is selected in the range of 26-30mm. while the composition of the starting gas is selected such that the rare gas having the atomic weight higher than that of Ar is contained less than 5vol% while the rare gas having the atomic weight lower than that of Ar is contained less than 5vol% and the remainder is Ar. The starting gas is encapsulated under the encapsulation pressure of 1.5-3.0mm.Hg. Consequently improved starting characteristic and tube characteristic and excellent power save effect are achieved.
