![]() ![]() An electrode structure (for example, refer to Patent Document 2) in which a low-scattering object shielding ring is attached to an introduction line is known. ![]() The discharge electrode is a secondary electron emission coefficient so as to surround an electrode structure (see, for example, Patent Document 1) that forms a space with a metal cylinder or a discharge electrode that is joined to an introduction line. ![]() The sintered metal body is interpolated and joined to the lead-in wire, and the second metal cylinder is attached so as to cover the first metal cylinder, whereby the outer surface portion on the bottomed side of the first metal cylinder and the second metal cylinder are attached. The present invention relates to an electrode structure of a cold cathode fluorescent tube having a relatively large tube diameter that is used, for example, as an advertising backlight. Figure 2 Description Translated from Japanese Further, the annular ceramic cover 6 and the glass tube 7 may be integrated to form a glass tube with a cover so as to have translucency. At this time, first and second locking projections k 1 and k 2 projecting inwardly before and after the glass tube 7 are provided to prevent dropping. As an electrode structure 1 of a cold cathode fluorescent tube having a tube diameter of about 15.5 to 38 mm, an annular ceramic cover 6 is attached to a tip opening of a cylindrical discharge electrode 5 made of an iron-based material, A glass tube 7 having translucency is placed on the outside and integrated.
