Description of the Invention: </ RTI> The present invention relates to a cold cathode fluorescent lamp, and an electrode and an electrode unit constituting a part of a cold cathode glory lamp, particularly an electrode structure of a cold cathode fluorescent lamp. [Prior Art] Cold cathode fluorescent lamps are easy to use, low in power consumption, and long in life. In recent years, they have been commonly used for backlights of liquid crystal panels. The cold cathode fluorescent lamp generally has the following structure: a pair of electrodes are disposed opposite each other inside a glass tube filled with a rare gas and a mercury gas, and the wires are connected to the respective electrodes. The electrode system is formed into a cup shape and disposed such that the opening portions of the cup face each other. If a voltage is applied to the electrode through the wire, electrons are emitted from one of the electrodes, collide with the mercury atom, and generate ultraviolet rays. Ultraviolet rays are converted into visible light by a fluorescent film formed on the surface of the glass tube, and visible light is emitted from the inside of the glass tube. Therefore, the life of the cold cathode fluorescent lamp is highly correlated with the consumption of mercury gas. • The electrode is usually made of nickel. For example, it is 99.7% nickel, 0.1% manganese, 0.1% iron, and other impurities (carbon, antimony, copper, sulfur) 〇1%. In the chain 3 has a trace amount of cobalt of about 0. 0 U. The above mixing ratio is % by weight. If nickel is hit by argon or the like inside the glass tube, the helium atoms will be knocked out and scattered. This phenomenon is called sputtering. The scattered nickel atoms become amalgam due to the intrusion of mercury atoms, so the effective amount of mercury gas reduces the result, which consumes mercury gas and is associated with a decrease in the life of the cold cathode fluorescent lamp. Therefore, in recent years, some people have explored the use of electrodes with good splash resistance, 2138-7731-pf; Ahddub 5 1306617 and seek to extend the life of cold cathode fluorescent lamps. Specifically, there has been a technique of using a cup electrode such as copper (M〇) or niobium (Nb) which has a low work function as compared with a lock and has excellent sneezing performance. <Details of the Japanese Patent Publication No. 2002-358992 and Japanese Patent Application Laid-Open No. Hei No. Hei. + However, cold cathode fluorescent lamps using these metals have the following problems. First, use high-brightness metal such as turning or sharp. "The electrode has surface oxidation when sealed in a glass tube. Specifically, in the manufacturing step of the cold cathode fluorescent lamp, after the electrode is disposed at the end of the glass tube, the sealing glass (glass beads) at one end of the glass tube is placed in the atmosphere as a gas burner. The same is fired to make it sealed in a glass tube and hermetically sealed. However, when the glass beads are melted, heat is transferred to the electrodes and the surface of the electrodes is oxidized by heat. If the surface of the electrode is emulsified, it is not possible to produce special splash resistance due to a drop in splash resistance. Further, since molybdenum or niobium is not easily reduced once it is oxidized, it is difficult to reduce it by an atmosphere such as hydrogen in the subsequent step. Second, since molybdenum or niobium is a high melting point metal, when the wire is welded to the electrode, it is necessary to use very high heat to obtain sufficient joint strength. In particular, the melting point of molybdenum is about 340 (TC, which is more commonly used as the melting point of Kovar (k〇var) used as a wire (about 155 〇. 〇 is much higher, it is necessary to make the wire fully melt and bond However, since the molybdenum electrode hardly melts, the joint strength may not be obtained as a result. If a temperature at which the molybdenum electrode can be sufficiently melted is applied, the temperature applied to the wire is too high, and the joining becomes difficult. When using a copper wire filled with a double-structured wire made of Kovar, the copper has a melting point of 1 〇 8 〇, which is lower, so There is an internal copper melt first, and 2138-7731-PF flows out during the fusion; Ahddub 6. 1306617. Copper acts as a heat release tool for the heat of the electrode to escape from the outside of the glass tube when the lamp is used. However, if copper flows out, In the interior of the outer tube made of Kovar, there is a void that is not filled with copper, which is related to the deterioration of the heat release performance. Third, (4) 铌 - generally expensive, use When the electrode of the substrate is compared with the electrode made of nickel, it is easy to increase SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides a cold cathode fluorescent lamp which is excellent in spatter resistance and manufacturability and economical. The cold cathode fluorescent lamp of the present invention has a glass tube. At least a rare gas and a mercury gas are sealed in the inner space of the hermetic seal, and a phosphor layer is formed on the inner wall surface in the inner space; and the cylindrical electrode has a bottom portion formed at the 9-end and an opening portion at the other end, and the opening portion They are arranged opposite each other; and one end of the wire is joined to the bottom surface, and the force end is pulled out to the outside of the glass tube. The cylindrical electrode is made of nickel or nickel alloy as the _ IF two coffins, and is added with deoxidation. The metal material is formed. The metal to which a material based on a nickel or a nickel alloy is added has a property of segregating oxygen from the outside and is easily segregated into crystal grain boundaries in the form of an oxide. The tendency of the crystal grain boundary to be selectively formed by the combination of each other's knives, so that the combination of the particles of the crystal grain boundary can be enhanced by the use of the radix moxibustion oxides, and the spray resistance can be improved. The cold cathode fluorescent lamp of the present invention has a low melting point of nickel or σI as a substrate. Therefore, the heating at the time of bonding with the wire can be further improved at a low temperature. Furthermore, 2138 -7731-PF; Ahddub 7 .1306617 The cold cathode fluorescent lamp of the present invention has nickel or a nickel alloy as a base material, and therefore has a good workability as a cylindrical electrode, and is also effective for reducing the material cost. The metal is preferably titanium, and the mixing ratio of titanium is preferably 〜·〇1 to 2.0% by weight. The metal having deoxidation can also be a cone, and the wrong one is 05~1. 1% by weight. The metal having deoxidation can also be used. For the purpose of giving, the mixing ratio of 铪 is preferably 〇· 05~1 _ 1% by weight. The wire may be of a two-layer construction: the outer peripheral portion is formed of an electrical conductor, and the inside is filled with copper or a copper alloy. "The electrode of the present invention is a cylindrical electrode used in a cold cathode fluorescent lamp, the bottom portion is provided at the end, and the opening portion is provided at the other end, and the alloy is recorded or recorded as a substrate, and is added by deoxidation.

The envelope 0 surrounded by the inner wall surface 4 is a total of 0, and the glass interior space 5 is sturdy. ^ Search for rare gases and mercury, and reduce the internal pressure to a very large amount of atmospheric pressure. A pair of electrode units 6 are provided at both ends of the longitudinal direction of the glass tube 2. At least 7° 6 is composed of a cylindrical electrode 7 and a wire 9 joined to the bottom surface portion 8 of the cylindrical electrode 7. The cylindrical electrode 7 of each electrode unit 6 = 2138-7731-PF; Ahdciub 9 1306617 The position in the longitudinal direction of the internal space 5 of the glass member 2 is slightly inside, and the opening portion 1 of the cylindrical electrode 7 is Further, the opening portions 10 of the electrode unit 6 are arranged to face each other. One end of each of the wires 9 is melted to the bottom surface portion 8 of the corresponding cylindrical electrode 7. The other end penetrates the glass beads 3 and is pierced from the outside of the glass tube 2. The wire 9 is made of a conductive material such as Kovar (6). Fig. 2 is an enlarged perspective view of an electrode unit 6 having a cold cathode discharge lamp j. The cylindrical electrode 7 constituting the electrode unit 6 has an opening portion 10' on one side in the longitudinal direction and a cylindrical portion 23 which is closed by the bottom surface portion 8 on the other side. The cylindrical electrode 7 presses a metal plate into a cylindrical shape (cup shape). One end surface 12 of the wire 9 is welded to the bottom surface portion 8 of the cylindrical electrode 7. The cylindrical electrode 7 is made of nickel or a recording alloy as a base material, and is made of a material to which a deoxidizing metal (hereinafter referred to as an additive) is added. As the additive, for example, titanium, zirconium, or titanium is given. The mixing ratio of titanium is preferably 混合1 to 2 〇% by weight, and the mixing ratio is preferably mu% by weight, and the mixing ratio is preferably 0.05 to 1.1% by weight. The upper limit of each mixing ratio mainly determines the manufacturability of the cylindrical electrode 7. That is to say, if the mixing ratio is higher than the above, the material becomes hard and it is difficult to press into a cylindrical shape. The lower limit of each mixing ratio is set so that sufficient splash resistance can be obtained, as will be described later. The composition of the examples is: 9 g. 7 %, titanium 〇. 〇 5 %, mammoth . 15 %, other impurities (carbon, bismuth, copper, sulfur, magnesium, iron) 0-1%. 01左右左右的小钴。 In addition, nickel containing about 0.01% trace of cobalt. The reason why the splash resistance of the tubular electrode 7 is improved by mixing the metals is described with reference to Fig. 3 . The following is an example of titanium, but the same is true for 鍅 and 铪. The nickel or nickel alloy is generally of a polycrystalline structure, at the junction 2138-7731-PF; Ahddub 10 .1306617, the boundary surface of the crystal G, < Since the interparticle-to-particle combination of the crystal grain boundary B is weak, the striaphile B valley is susceptible to splashing. The splatter is mainly from the grain boundary and slowly expands to the inside of the crystal G. In the case of molybdenum or niobium, if oxidized, sneezing proceeds remarkably from the crystal grain boundary B. These substances - the quality as described above, - g - broken oxidation is not easy to reduce 'so it is difficult to restore the resistance to splashing - splashing performance. 1. In contrast to the present invention, the deoxidation characteristics of titanium are utilized. That is to say, the addition of the % of the pain to the nickel has a tendency to be segregated in the grain boundary B, and titanium is no exception. Further, in the case where the titanium is sufficiently segregated to the crystal grain boundary B and the oxygen from the outside is extracted, the bonding force between the crystals of the crystal grain boundary B can be improved, and the sneezing resistance of the electrode can be improved. The minimum value of the aforementioned mixing ratio is as follows: the door is resistant to splashing and the sufficient titanium is distributed in the crystal grain boundary.

In the test, a large number of samples with different additions (% by weight) were added to the recording, and the spatter resistance and workability were evaluated. The comparison between the evaluation department and the purely recorded book was determined to be 1 2 3 and 4 in order of goodness. Purely recorded splash resistance is not very good, it is set to 3, and the processability is good. Therefore, it is determined that the performance of the electrode is determined by visually determining the amount of splashing of the electrode, and the amount of splashing is less. $ starts from 1, 2, and 3. The workability is formed into a cup-shaped electrode. The potential of the molded body is determined by the comprehensive consideration of the accuracy of the formed shape and the presence or absence of defects, and is determined to be 1, 2, 3, and 4 in good order. : The workability is only 4, which is not suitable for practical workability, and 3 is qualified as follows. Further, the sample having a splash resistance of 3 was used as the pure nickel phase 2138-7731-PF; Ahddub u 1306617: the benefit was due to 1^, and was not used. In this way, the results of V of each sample were as shown in Table 1. The samples having good sputtering performance and workability are 2nd to Rth. , at 8, 8, 12 (the bottom of the table). In this way, it was confirmed that the performance of an electrode in which nickel, niobium, and tantalum were added as an additive substance was significantly higher than that of a conventional nickel-based (no additive) electrode. In particular, a sample containing 5% by weight of titanium ruthenium was excellent in spatter resistance and processability.

The tubular sister 7 has a nickel or a recording alloy as a substrate, and the ratio of the added substance is low. Therefore, the melting point is substantially equal to the recorded refining point (脳.c). The melting point of the cylindrical electrode 7 is substantially the same as the melting point of the material of the wire 9, that is, the starting point of the Kovar nickel (1 550. 〇, so when the wire 9 is spliced to the cylindrical electrode 7 and fixed, two The softening is the same degree, and they are mutually 2138-7731-PF; Ahddub 12 .1306617 is melted into an alloy and firmly fixed. In contrast, when the electrode is composed of a key-equivalent metal, the wire 9 can only be melted. Fixing, it is easy to produce a limit on the adhesion strength or the adhesion step. The invention can solve the problem such as = at the same time. Furthermore, the cold cathode fluorescent lamp of the invention has a low mixing ratio of the added substances, thereby enabling cost The effect is minimized. That is to say, since the cold cathode fluorescent lamp of the present invention is made of a recording or recording alloy, the cost is not far from the electrode of the recording or nickel alloy, and an economical cold glory lamp can be provided.

The cold cathode love lamp of the present embodiment differs from the third embodiment in the configuration of the catheter. The other portions are the same as the embodiment of the 帛i. Therefore, only the configuration of the catheter will be described, and the same portions as those of the first embodiment will be omitted as shown in Fig. 4. The wire constituting the electrode unit 61) has a multi-layer (double-layer structure): (k〇var) constitutes the inside of the outer side Μ, and the inner portion & portion 32 made of copper (Cu) or a copper alloy is inserted to heat the heat generated by the electrode to provide a front end portion The periphery is surrounded by a copper-clad structure Wt) 34' and connected to a power supply device (not shown) via a Dumei line 34. The cylindrical electrode 7 and the first! Similarly, in the embodiment, a substrate is recorded or recorded, and a material to which a metal such as titanium, erbium, or ytterbium is added is formed on the substrate. Therefore, regarding the splash resistance (4) i implementation 完全 completely - like. Further, the melting point of the cylindrical shape is the same as the recorded refining point because the bonding to the wire 9b does not require an excessively high temperature. Therefore, the inner portion 32 of the wire 9b is overheated due to heat welding, and the possibility of copper being blown out to the outside is possible. Subtract 2138-7731_PF, -Ahddub 13 1306617 • Small. Therefore, the heat dissipation of the wire 9b can be sufficiently ensured. Although the present invention has been described above with respect to the embodiments, the present invention is of course not limited to the above embodiments, and various modifications can be made. For example, titanium, tantalum, and niobium are listed as additives, but these may be used in combination. Further, the portion that is easily splashed is the bottom surface of the cylindrical portion 23 of the cylindrical electrode and the portion on the side of the portion 8. Therefore, it is possible to mix only the metal having the deoxidation effect in the portion, and it is also possible to increase the mixing ratio of the metal having the deoxidation effect in the portion. The present invention has been described with reference to the preferred embodiments of the present invention, and it is understood that various changes and modifications may be made without departing from the scope and scope of the appended claims.
