Electrode material

Abstract

The invention relates to electrode material which is characterized in that it has a fluorophor layer on its inner wall, a glass tube with rare gas and mercury sealed in it and a pair of electrodes which are equipped on the two ends of the glass tube. Wherein the electrodes are comprised with Ni alloys, the Ni alloys comprise at least one element out of the basic group comprised with rare-earth element Ti, Hf, Zr, V, Fe, Nb, Mo, Mn, W, Sr, Ba, B, Th, Be, Si, Al, Y, Mg, In, which total mass is greater or equal to 0.001 mass percentages and less or equal to 5.0 mass percentages, and the rest of the alloys is Ni and other foreign materials. As the electrode is comprised with Ni alloys, it has the advantages of having good discharge character, oxidation resistance, sputter resistance and reaction resistance of mercury.

Description

technical field [0001] The present invention relates to an electrode material suitable for an electrode of a cold cathode fluorescent lamp, a method for manufacturing an electrode for a cold cathode fluorescent lamp using the electrode material, and a cold cathode fluorescent lamp. In particular, cold-cathode fluorescent lamps with higher brightness and longer life are involved. Background technique [0002] At present, cold-cathode fluorescent lamps have been fully utilized as light sources for original irradiation of image scanners, liquid crystal monitors of personal computers, and liquid crystal display devices (liquid crystal displays) such as liquid crystal televisions. : refer to JP-A-2004-71276, JP-10-144255). CCFLs have, for example figure 1 structure shown in . figure 1 It is an example of a cold cathode fluorescent lamp, and is a cross-sectional view showing its schematic structure. The cold cathode fluorescent lamp 100 has a glass tube 102 in which a phosphor...

AI Technical Summary

Problems solved by technology

As a result, the consumption of the electrodes and the formation of amalgam are accelerated, leading to a reduction in the life of the fluorescent lamp

If the electrode is enlarged, the disadvantages caused by sputtering can be reduced, but in this case, there are the following problems: 1. It deviates from the requirements for thinning and miniaturization; 2. The non-light-emitting part becomes larger

However, these electron-releasing substances are scattered by the impact of ions generated by the discharge during lighting of the lamp, so it is difficult to further extend the life of the lamp.
