COLD CATHODE FLUORESCENT LAMP, MANUFACTURING METHOD THEREOF AND ADSORPTIVE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a cold cathode fluorescent lamp capable of achieving a significant reduction in impurity gases/particles in a tube, improvements in emission efficiency and operation efficiency, and a long life due to a reduction in operating voltage. SOLUTION: This cold cathode fluorescent lamp comprises a light transmissive tube 200 and at least one cup-shaped adsorptive structure 202. The light transmissive tube 200 is sealed and filled with a gas that emits light through excitation by application of a voltage. The adsorptive structure 202 is disposed at an end of the tube 200, and comprises a supporting member 204 having an opening 214, and an adsorptive material layer 206 that fills the opening 214.
