ELECTRODE MOUNT, ARC TUBE, LOW-PRESSURE MERCURY DISCHARGE LAMP, COMPACT SELF-BALLASTED FLUORESCENT LAMP, AND MANUFACTURING METHOD OF ARC TUBE

摘要

PROBLEM TO BE SOLVED: To provide an electrode mount or the like capable of realizing a fluorescent lamp of a smaller bulb shape or the like.;SOLUTION: The electrode mount 61 is provided with a filament coil 41, a pair of lead wires 43, 45 supporting the filament coil 41 at an end, and bead glass 47 retaining the pair of lead wires 43, 45. The arc tube includes an arc tube main body 31 formed by curving a glass tube, and an electrode 33 sealed to an end part 3a of the arc tube main body 31. For the electrode 33, an electrode mount 61 is used. Sealing of the electrode mount 61 at the end part 3a of the arc tube main body 31 is made at a region of the lead wires 43, 45 positioned between the filament coil 41 and the bead glass 47, and the bead glass 47 is disposed outside the arc tube main body 31.;COPYRIGHT: (C)2008,JPO&INPIT
