Abstract

PURPOSE:To reduce the painting amount of an expensive rare earth element fluorescent with high efficiency and high color renderability as well as control the increase of power consumption of lamp by confining a mixed rare gas containing mercury and a specific amount of krypton in a tube of a specific diameter with a specific charging pressure. CONSTITUTION:A mixed rare gas, consisting of mercury gas and a charging gas containing 30-70% krypton, e.g., krypton-argon, krypton-neon, or krypton-argon- neon, is confined into a rapid start type 110W straight tube fluorescent lamp, approx. 2,400mm. long and 32-35mm. in diameter, with a charging pressure of 1.5- 2.5 torr. Thus, the rise of lamp voltage can be suppressed, the power of the lamp can be controlled to a specified standard value or less, starting can be made easier, and the life of the lamp can be lengthened.
