MOUNT FOR THERMIONIC CATHODE FLUORESCENT LAMP, AND THERMIONIC CATHODE FLUORESCENT LAMP

摘要

PROBLEM TO BE SOLVED: To provide a mount for achieving a thermionic cathode fluorescent lamp having a thin tube diameter and stable light emitting performance and high reliability, and to provide a thermionic cathode fluorescent lamp using the same.;SOLUTION: The mount is composed of a filament electrode 2, leading-in wires 3 and an exhausting tube 4, and an opening end 4a of the exhausting tube 4 is of a funnel shape and the leading-in wires 3 supporting the filament electrode 2 is made to penetrate airtight into the opening end 4a of a funnel shape. Then, the opening end 4a of the exhausting tube 4 with the leading-in wires penetrated and an opening end of a glass tube are fusion-bonded to seal both ends of the glass tube by the mount 7.;COPYRIGHT: (C)2010,JPO&INPIT
