The arc tube 10 includes a glass tube 12 encapsulated with an appropriate amount of mercury and an inert gas, and a phosphor 13 disposed on the inner surface of the glass tube 12. The cold cathode fluorescent lamp electrode 2A connected to the end of the arc tube 10 includes a cup electrode 22 and an electrode lead 25. The cup electrode 22 is located inside the arc tube 1 , and may be any material selected from the group consisting of conductive metal tungsten (W), molybdenum (Mo), nickel (Ni), niobium (Nb), and niobium (7) or Made of alloy, it can also be made of K〇var or the alloy of Kovar and Y (Y).

The inner lead 27 is connected to the glass tube 2, and one end extending toward the inner side of the glass tube 12 is joined to the cup electrode 22 by soldering. The inner lead 27 has a cylindrical shape, and the inner lead length a is 2·5 to 3.5 mm, and the inner lead diameter di is preferably from 0.6 to 丨5 mm in consideration of resistance and strength. The outer lead 28 extending outward from the end of the glass member 12 is integrally formed with the inner lead 27 2 and is connected to an external power source (not shown) in a plug-in manner, and supplies current to the cup electrode 22 . . Therefore, the outer lead 28 also has a cylindrical shape 'having a length b of 2 to 8 mm, and its diameter d2 is substantially the same as the inner lead diameter dl, that is, preferably 〇.6 to le5 mm. The outer lead 28 and the inner lead 27 are made of the same hard material, that is, any one selected from the group consisting of tungsten 9 200845096 (wy (Mo), nickel (10), 铌 、, 纪 (7) or ', 5 to ' or by decua Made of (Kovar) or Kovar and γ (γ) alloys.

After the lead wires 28 and the inner leads 27 are connected by soldering, the electrode leads 25 are manufactured by forming the outer leads 28 and the inner leads 27 through the same body. In such a cold cathode fluorescent lamp, when an electric current is supplied from the external power source to the cup electrode 22 via the inner lead 27 through the outer lead 28, the inside of the arc tube 1 is caused to be released. The ultraviolet light generated by the discharge activates the phosphor U, and the generated and outward illumination can be used as a backlight for the liquid crystal display device. The cold cathode fluorescent lamp electrode according to the embodiment of the present invention is connected to an external power source (not shown) via a B-plug connection. Therefore, it is not necessary to connect the outer lead 28 to the electric wire connected to the external power source (not shown) by the soldering welding. Therefore, the same hard material as the inner lead π can be used instead of the soft material, and the outer lead 28 is inside. The lead wires 27 are integrally formed. Since it is not necessary to connect the outer lead 28 and the inner lead 27 @welding process, it is easy to manufacture. In addition, since there is no welded portion between the outer lead 28 and the inner lead 27, the phenomenon of breakage due to deterioration of the welded portion does not occur, or the resistance of the welded portion increases and the oxidation phenomenon hinders the passage of current. The problem of reduced performance. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, and it should be understood by those skilled in the art that it is within the spirit and scope of the present invention. Various modifications and changes can be made.
