The cold cathode fluorescent discharge tube null Ni which has the electrode and its electrode which for the cold cathode fluorescent discharge tube were formed with the electrode alloy and that electrode alloy for the cold cathode fluorescent

摘要

PROBLEM TO BE SOLVED: To provide an electrode alloy for a cold-cathode fluorescent discharge tube that has a longer lamp service life, as compared with that of the cold-cathode fluorescent discharge tube equipped with an electrode formed with pure Ni, superior cost benefit and superior moldability, and to provide an electrode for the cold-cathode fluorescent discharge tube, or the like, formed with the alloy.;SOLUTION: The electrode alloy is an Fe-based alloy constituted of containing 3.0 to 8.0% of Ni or Cr in % by mass and balance of Ni and unavoidable impurities. Moreover, this electrode for the cold-cathode fluorescent discharge tube is equipped with a tube part 3, in which one end is left open and an end plate part 4 to close the other end of the tube part 3, while the tube part 3 and the end plate part 4 are integrally molded by using the Fe-based alloy.;COPYRIGHT: (C)2009,JPO&INPIT
