Abstract

This invention relates to a cold cathode fluorescent lamp tube. Upon its wall surface, it builds fluorescent layer. It employs electrode combination in the internal airproof space filling with rare gas. It seals two ends of glass tube wall surface that coating with the mercury. The electrode combination comprises electrode, seal component, and wire. The electrode is deployed in the internal space. The seal component seals the two ends of glass tube. The wire is pulled out to glass tube outside. This seal component at least employs the multilayer structure that second metal material wrapping up and covering the first metal material. Comparing the first metal material to the second metal material, it has higher thermal conductivity, smaller resistance coefficient, higher thermal conductivity, and smaller resistance coefficient.
