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.

Embodiment Construction

[0041] Embodiments of the present invention will be described below. Electrodes for cold cathode fluorescent lamps were prepared using Ni alloys having the composition (metal Nos. 1 to 36) shown in Tables 1 and 2. The electrodes are made of two electrode materials with different shapes. Specifically, a linear electrode material and a plate-shaped electrode material are prepared. A cup-shaped electrode is produced by forging a wire-shaped electrode material, and a cup-shaped electrode is produced by pressing a plate-shaped electrode material.

Abstract

The invention relates to an electrode material having a glass pipe the inner wall surface of which is provided with a fluorophor layer and the inside of which is enclosed with rare gas and mercury, and a pair of electrodes arranged on two ends of the glass pipe; wherein the electrode is constituted by following Ni alloy which contains at least an element which is selected from a standard group composed of Ti, Hf, Zr, V, Fe, Nb, Mo, Mn, W, Sr, Ba, B, Th, Be, Si, Al, Y, Mg, In and rare earth elements and is more than or equal to 0.001% or less than or equal to 5.0% by mass, and the balance of Ni and impurities. The electrode is not constituted by Ni simple substance but the Ni alloy with the components as above, thus improving the electric discharge performance, oxidation resistance, sputtering resistance and reaction resistance to mercury, and realizing high brightness and long service life.

Description

[0001] This application is a divisional application of the Chinese patent application entitled "Electrode Material" and application number 200610084559.2 submitted to the China Patent Office by Sumitomo Electric Industries, Ltd. and Sumiden Precision Conductor Co., Ltd. on May 25, 2006. technical field [0002] 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 [0003] 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-...
