ELECTRODE STRUCTURE, LOW-PRESSURE DISCHARGE LAMP, ILLUMINATION DEVICE, AND IMAGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To use a low-pressure discharge lamp having a large tube diameter by improving a sealing property of a glass tube having a large tube diameter. SOLUTION: An electrode structure 100 includes: an electrode 101; a lead line 102 of which one end is connected to the electrode 101; and a glass bead 103 formed to cover at least a part of the lead line 102. The glass bead 103 has a multilayer structure. COPYRIGHT: (C)2011,JPO&INPIT
