Abstract

In a cold cathode fluorescent lamp aiming at lengthening, downsizing and increasing mechanical strength of translucent tubes as well as aiming at high brightness of the lamp, the problem is to provide solder for connecting lead lines in a cold cathode fluorescent lamp that can control occurrence of rubbing sound at the connections of lead lines using the solder that supply a large amount of current to electrodes and conduct heat generated at the electrodes to the outside of the translucent tubes. The solder includes Tin and bismuth as main constituents and also includes copper and phosphorus. It is preferred that the tin content in the solder is 50 mass% to 85 mass%, the bismuth content being 15 mass% to 50 mass%, the copper content being more than 0 mass% less than 1.0 mass% and the phosphorus content being more than 0 mass% less than 0.1 mass%, provided that the total of the contents is 100 mass%.

Description

201032939 VI. Description of the invention: - [Technical field of invention] The thief of the material is smashed in this continent. [Previous technology] Force ίϊ ί ΐ 因为 because of high Μ, high color, long life, low power consumption ί 'It is widely used in the back field of He, the pulse source, the photocopier (10), the light source, and various display screens. The cold cathode fluorescent lamp has the following constitution, for example. Second, the both ends of the light-transmitting wire 2 such as the glass of Table 7F are sealed by bead glass or the like, and the member 3 is hermetically sealed. Omm的范围。 The outer diameter of the light-transmitting tube 2, for example, a range of L 5~6· 〇, preferably 1. 5~5. The light-weight layer 4 is disposed on the inner wall surface of the light-transmitting tube. The county body of the phosphor layer is composed of a phosphor selected from a phosphor that emits green light, a phosphor that emits blue light, and a phosphor that emits red light, and may be emitted. White light. Mercury and a rare gas, for example, helium, etc., are quantitatively introduced into the internal space 5 of the light-transmitting tube, and the internal pressure is reduced to about a tenth of the atmospheric pressure. At the longitudinal ends of the light transmission tube, cup electrodes 7 are disposed opposite to the opening portion 1A. The leads 9' are respectively soldered to the cup-shaped bottom surface of each electrode. The other end of each lead penetrates the sealing member 3 and is taken out to the outside of the light-transmitting tube. In such a cold cathode fluorescent lamp, when a voltage is applied between the electrodes, the rare gas is electrically ionized because of a small amount of electrons present in the light transmitting tube. The ionized rare gas collides with the electrode to release secondary electrons, causing glow discharge. Ultraviolet rays such as 253·7 nm and 360 rm are emitted from mercury excited by the glow discharge. The phosphor which emits blue, green, red light or the like is provided by the inner wall of the light-transmitting tube which receives the ultraviolet ray, and the light is mixed, and the white color is emitted after the color is reproduced. Such a cold cathode fluorescent lamp requires a thinning and a small diameter for the light transmission tube, and a high mechanical strength 3 201032939 electric, sub-cold = burn light lamp, while the liquid crystal display device is required to be thinned and the area is increased. At the same time as the high-brightness requirements are required, the exhaust gas, the electric motor, and the electric motor can be found in the electrode portion. In such a cold cathode lamp, it is preferred that the electrode is not subjected to oxidative degradation during soldering, and that the wire is not only similar to the sealing member in manufacturing, but also caused by heat generated. The thermal expansion volume changes, and the sealing member can also be; the holding gas 'two, that is, because of the thermal change, in the lead, as shown in Figure 4, the scorpion vortex is such a chrome alloy line (four) line 9a, In the transparent part, the copper-iron-nickel power supply is used to connect the solder to the y============================================================================= However, the socket is slipped and a slip sound occurs. The wire expands due to the heat of conduction.

[Patent Document 1] 2002-180226 [Draft] [Problems to be Solved by the Invention] The purpose of this Ming Ming is to provide a kind of cold and yin-turned soft solder 201032939. In the cold cathode fluorescent lamp that achieves the long strip of light-transmissive tube: brightness: brightness: ^^: The occurrence of the sliding sound is achieved. The joint part of the soft cloth is used to suppress the [technical means of solving the problem] 参❿,, the lion, the invention is related to a kind of cold yin, including ^ί光Si 征 You have used the cold cathode fluorescent lamp _ joint, its special [effect of the invention] The cold cathode fluorescent lamp of the present invention is used for soft ------ [Embodiment] The invention of the invention is characterized in that the soft solder for the lead of the fluorescent lamp is characterized in that it is given by tin. Knife and 3 have copper and phosphorus. Tin can be used for the connection with soft solder, to the good surface and the connection of the lead (C) is improved, and the content of the material is 50% by mass or more. The content of the other metals in the bamboo material is preferably the ratio of the desired amount of the metal, and the ratio of the tin phase is (10) mass%. The content of tin is 5G or more. 于 ^ at 201032939 It is soft U. If the content of tin is less than 85% by mass, the sliding sound that can be caused by sliding with the connecting body can be connected. In the case of expansion, the connection can be ensured to give strength, that is, 吏 in the daily lead expansion Between the connectors, it is ίίί=closed, which can suppress the connection with (10) and the soldering station. ί Even if the lead is swollen, it can maintain the connection with the connected ▲ =__, which can be __ high hardness and mechanical strength “ Ϊ 所 所 “ = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Ϊα 〇\' ίπ_Soft solder coloring. The scale is in the middle of the soft itch material, and it is possible to suppress the method of cooling and solidifying the lead and the bonded body of the bonded body due to the deterioration of the connection. In addition, metal salts such as 201032939 are mixed in a desired ratio. For the lead wire of such a cold cathode fluorescent lamp, there is no turning, limit, and 2 (= == iron around the core wire 11 of the alloy and the recorded alloy. i 12 Ϊ 仏 can be exemplified by 〇. 6mm, the film thickness of the copper layer can be exemplified by the straight copper layer of the heart line ' Combine the quotation 1 to the heterogeneous ^®. The lead is solvent-treated to remove copper oxide to form a good fusion. The layer ^' can also be used to seal the light-transmissive tube with a sealing member.
