发明名称 ELECTRODE FOR COLD-CATHODE FLUORESCENT LAMP
摘要 A cold-cathode fluorescent lamp having high brightness with long life and an electrode for this lamp are offered. The electrode comprises a base and a covering layer that covers the surface of the base. The base is formed of one metal selected from nickel, a nickel alloy, iron, and an iron alloy. Consequently, a base having a shape, such as a cup, can be easily produced. The covering layer comprises (a) a surface layer made of tungsten or molybdenum and (b) a bonding layer that is made of zinc alloy and that is placed between the base and the surface layer. In comparison with nickel and iron, tungsten and molybdenum are resistant to sputtering, have a small work function, and have a high melting point. The presence of the bonding layer enables sufficient bonding between the surface layer and base. A cold-cathode fluorescent lamp provided with the foregoing electrode can suppress the reduction in brightness and the consumption of the electrode. Therefore, it has high brightness and long life.
