COLD CATHODE DISCHARGE LAMP

摘要

PROBLEM TO BE SOLVED: To provide a cold cathode discharge lamp which suppresses sputtering of a lead-in wire to increase the life of the cold cathode discharge lamp. SOLUTION: In this cold cathode discharge lamp, a surface of an inner lead-in wire 4a is formed of material having a work function value higher than that of material forming an inside surface of a cylindrical electrode 5.
