ELECTRODE FOR COLD CATHODE FLUORESCENT LAMP

摘要

This invention provides a high-brightness and long-service life cold cathode fluorescent lamp and an electrode for the lamp. At least a part of the surface of the electrode is formed of one material selected from the group consisting of rhodium, palladium, and alloys of these metals. For example, a surface layer formed of the above material is formed on the base material. Further, in order to enhance the adhesion between the surface layer and the base material, a bonding layer of gold or a gold alloy is formed on the base material. Since metals such as rhodium are less likely to be alloyed with mercury and have a high melting point, a cold cathode fluorescent lamp provided with an electrode formed of this metal can reduce such unfavorable phenomena that mercury is consumed as a result of formation of amalgam and the brightness is lowered due to unsatisfactory discharge. Further, since the consumption of mercury and the consumption of electrode can be reduced, the lamp has a prolonged service life.
