[Prior Art] There are many types of gas discharge tubes containing mercury, such as cold cathode fluorescent 10 15 (CCFL) and straight tube type domestic hot cathode fluorescent lamps (also known as neon lamps). High-pressure mercury lamp, external electrode fluorescent lamp (referred to as EEFL lamp official), ultraviolet lamp, high-power mercury rectifier, mercury switch tube, etc. These discharge tubes are widely used, such as cold cathode fluorescent lamps, which have a simple structure, compact tubes, high surface brightness, small temperature rise of the tube, and long service life. The mouth is widely used as a novel miniature strong light source. Products such as liquid crystal display, scanners, car dashboards and micro advertising light boxes. In the prior art, a mercury-containing gas discharge tube includes glass; a shell, an electrode disposed at an end of the glass envelope, a filling in the glass envelope; or a plurality of inert gases and mercury vapors and coating on the inner wall of the envelope On the rong $ powder. Figure 1 shows a coffee tube as a typical mercury-containing gas discharge tube. As shown in the figure, the conventional (10) includes: a face tube shell 2, a plaster 4 coated on the inner wall of the envelope, a gas enclosed in the tube (for example, a wind and a milk vapor) 5 and a lamp. The electrode 1 includes the electrode wire (the crane wire, the Dumet wire or the Kovar alloy 6) and the nickel tube or the nickel tube 3 welded on the wire 6 at the end of the tube. The side of the bag is conventionally not provided with a suction device in the gas discharge tube containing mercury, because 20! 282574 may absorb the mercury in the gas discharge tube together. However, the discharge tube is used. The phosphor powder in the glass and the tube will continuously discharge the adsorbed impurities during the long-term lighting operation, and will diffuse out the gas impurities and the active low-melting metal from the inside of the material 5. Since there is no getter, these gas impurities And the active metal enters the inside of the discharge tube, which will increase the internal resistance of the discharge of the gas in the discharge tube, thereby causing the material in the discharge tube to "poison" and partially lose its function. This seriously affects the service life of the mercury-containing gas discharge tube. The object of the present invention is to solve the above technical problems, and to provide a getter device for a mercury-containing gas discharge tube, which can effectively absorb impurities in the discharge tube while not absorbing mercury, thereby greatly Extending the life of the discharge tube. Another object of the present invention is to provide a mercury-containing gas discharge tube comprising the getter device 15. According to a first aspect of the invention, an air device for a mercury-containing gas discharge port is provided, The crucible includes at least one alloy body (ie, a sintered metal body) disposed inside the mercury-containing gas discharge tube, wherein the alloy body is comprised of at least one high temperature resistant metal and at least one iron group metal within 20 Preferably, the alloy body can be set as a porous alloy cylinder or a porous alloy sheet, and the porous porosity can be set in the range of 5% to 96%. The iron group metal includes iron, cobalt and nickel. At least one type of refractory metal includes at least one of crane, cockroach, neon, and sharp, and their total composition is in the range of % 5 1282574. According to the present invention In another aspect, there is provided a mercury-containing gas discharge tube comprising the above-described getter device, comprising a glass envelope, an electrode wire disposed at an end of the glass envelope, an inert gas or a plurality of inert gases filled in the glass envelope a mercury vapor and a phosphor powder coated on the inner wall of the envelope, wherein a getter device according to the present invention is disposed on the wire electrode. In this case, the electrode in the discharge tube is built in, and the built-in type The discharge tube of the electrode may include a CCFL, a fluorescent lamp, a high pressure mercury lamp, etc. According to another aspect of the present invention, there is provided a gas discharge tube containing silver, comprising a glass envelope, a wire disposed at an end of the glass envelope, and charging One or more inert gases and mercury vapors in the glass envelope, wherein a getter device according to the present invention is disposed on the wire electrode. In this case, the electrode in the discharge tube is still built in, and the lamp tube includes Straight tube type UV disinfection lamp. According to another aspect of the present invention, there is provided a mercury-containing gas discharge tube comprising a glass envelope, one or more inert gases and mercury treatment gas filled in the glass envelope, and a glass exterior at the end of the envelope a coated conductive coating, a power supply lead ring connected to the conductive paint, and a phosphor powder coated on the inner wall of the glass envelope, wherein the gas discharge tube further includes at least one getter according to the present invention Device. In this case, the electrode in the discharge tube is external, and the discharge tube of the external electrode may include a mercury-containing gas discharge lamp of a straight tube type external electrode, wherein the getter device may be at the tube end The portion is caught by a glass shrinkage or disposed in the middle of the envelope. 1282574 In the present invention, since the above-mentioned inclusion of at least one iron group metal is used, the gettering I is placed, and thus the oxygen, nitrogen, carbon monoxide, carbon dioxide, water vapor and the like are greatly affinitive, and can be combined with this (4) The mass gases quickly produce compounds that absorb them. The alloy body of the present invention hardly reacts with mercury vapor as compared with the commonly used getter, and thus does not affect the uniformity and service life of the lamp. In the same way, the inhalation skirt of the present invention can also function as an electrode while absorbing impurities. Since the getter device includes a porous alloy cylinder or a porous alloy sheet having a large surface area, the absorbed electron-emitting material is also several times larger than that of the conventional mercury-containing gas discharge tube. In this way, the number of electrons emitted from the surface of the getter device increases greatly as the power of the mercury-containing gas discharge tube increases, and the discharge tube can withstand a larger operating current while still being in a stable working state. . On the other hand, since the alloy of the getter device includes at least one metal having high temperature resistance, the operating current of the discharge tube is also increased, and accordingly, the surface redundancy is also increased by Ik. Therefore, the gas discharge tube according to the present invention has a much higher photoelectric parameter than a conventional gas discharge tube. The mercury-containing gas discharge tube according to the present invention can withstand a working current twice as large as that of a conventional mercury-containing gas discharge tube without shortening the working life, and the surface brightness thereof is also remarkably improved. However, if the operation is carried out at the same operating current as a conventional aqueous silver gas discharge tube, the life of the mercury-containing gas discharge tube of the present invention can be increased by 1 to 1.5 times. [Embodiment] Hereinafter, a detailed description will be made of the mercury-containing gas gas of the present invention and its getter device with reference to the accompanying drawings and the examples. The same or corresponding components in the drawings are denoted by the same reference numerals. The above and other objects and advantages of the present invention will become more apparent from the following description.
纟前文中已經提到，在衆多含水銀氣體放電管中，A =極螢光燈(CCFL)是最典型的。因此，在下文中，將首先 介紹包含本發明吸氣裝置的冷陰極營光燈的實施例。 圖2和圖3分別示出了根據本發明第一實施例的冷陰 極螢光燈管的結構及其吸氣裝置中多孔合金筒部分的二 f立體示意®。根據本發明的冷陰極螢紐管包括玻璃管 殼2、塗覆在管殼2内壁上的螢光粉4、封入管内的氣體卜 封裝在燈管端部的電極絲6以及在該電極絲上設置的吸氣 裝置7，其中，電極絲的兩端分別向燈管内側和燈管外側 延伸。 與圖1所示的現有技術的冷陰極螢光燈管不同的是， 15 S本發_冷陰極螢光燈管中0另外設置電極，而采用 包合至少一種耐高溫金屬和至少一種鐵族金屬的吸氣裝 置7來代替常規使用的鎳管3。該吸氣裝置7由—多孔^ 金筒構成，並通過例如焊接設置在燈管内側的電極絲6 上，從而在完成吸氣工作的同日寺，又可以很好地充當電極 20 的角色。 作爲CCFL燈管中最關鍵部件之一的電極，承擔著燈 官通電、發射電子 '建立磁場、加熱燈管等諸多功能，因 此燈管性能的優劣很大程度上取决于電極材料。但是目 前，在CCFL燈管中普遍使用的鎳管或錄筒是經過大比例 1282574 壓縮後拉制而成的，屬于緻密金屬，故其表面積受燈管内 裎和電極長度的限制，造成實際工作的表面積不够大。同 時，金屬鎳的熔點僅爲1453°C左右，所以在點燈工作時無 法承叉較大的燈管電流及較强的電子流和離子流的衝 擊，從而限制了燈管工作時表两亮度的提^但是，在使 用根據本發明吸氣裝置的冷陰極螢光燈管中，就不存在以 上的問題了。 因爲該吸氣裝置包括了孔隙度在5〇%_96%範圍内的 夕孔合金请或多孔合金片，其表面積很大，因此吸收的電 子發射材料也比常規的含水銀氣體放電管的電極要增加 幾倍。這樣一來，工作時該吸氣裝置表面發射出的電子數 就隨著該含水銀氣體放電管功率的增加而大量增加，放電 管因此可以承受更大的工作電流而仍然處于穩定的工作 狀態下。另一方面，因爲該吸氣裝置的合金中包括了至少 一種耐高溫的金屬，所以該放電管可以較大的電流進行工 作’相應地，其表面亮度也隨之增加了。因而，根據本發 明的氣體放電管，其光電參數要比普通的氣體放電管提高 很多。 當然，在該吸氣裝置的多孔合金筒或多孔合金片中， 還可以摻雜除本發明所規定的鐵、鈷、鎳、鎢、鉬、鈕和 銳七種元素之外的物質，只要其含量不超過5〇%，換言 之’本發明所規定的金屬元素的合計成分必須在所述吸氣 裝置全部材料的50%〜100%的範圍内。在此基礎上，所 述吸氣裝置7中所含有的本發明所規定的成分可從下組中 1282574 進行選擇： 1 ·鎢或銦或钽或鈮或鎢+鉬或鎢+鈮或鎢+钽或#目 +鈮或鉬+钽或钽+鈮或鎢+鉬+钽或鎢+鈕+鈮或癌 +在目+銳或钥+组+銳或鶴+麵+組+銳（70%〜9〇%) 5 /鐵或鎳或鈷或鐵+鎳或鐵+鈷或鎳+鈷或鐵+鎳+鈷（10 %〜30% ) 2 ·鶴或翻或组或銳或鶴+麵或鶴+銳或嫣+組或· +銳或錮+组或组+銳或鶴+錮+组或鶴+组+銳或鶴 +翻+銳或钥+组+銳或鶴+麵+組+銳（40%〜70% ) 1〇 /鐵或錄或始或鐵+錄或鐵+姑或鐵+錄+钻（30%〜60 %) 3 ·鎢或鉬或钽或鈮或鎢+鉬或鎢+鈮或鎢+钽或鉬 +銳或銷+组或组+銳或鶴+錮+钽或鶴+钽+鈮或鶴 +鉬+銳或顧+组+銳或嫣+銦+组+銳（10%〜40% ) 15 /鐵或鎳或始或鐵+鎳或鐵+始或鎳+始或鐵+鎳+始（60 % 〜90% ) 〇 由以上的成分所製成的吸氣裝置適用於根據本發明 的所有含水銀氣體放電管。 本發明的吸氣裝置7采用以上所述之一組的成分形 20 成。它一方面是一多孔製品，因而表面積比同樣規格的緻 推鎳管電極大2〜20倍以上；另一方面，又極容易吸收降 低電子發射能級的表面塗料，使其與吸氣裝置牢固結合， 並在長期工作過程中使之逐步而緩慢地釋放出來。 圖4和圖5分別示出了根據本發明第二實施例的冷陰 1282574 極螢光燈管的結構及其吸氣裝置中的多孔合金片部分的 放大立體示思圖。其與圖2和圖3所示的冷陰極螢光燈管 的區別僅在于，用多孔合金片8替代了合金筒7，故對這 個實施例不再詳細描述。 圖6示出的是根據本發明的CCFL連續點燈的壽命曲 綫。從曲綫的變化可以看出，在點燈的初期（約2〇〇小時）， 燈管的表面亮度明顯下降（約下降3%〜5%)。這是因爲 點k初期燈管内玻璃、螢光粉、電極内的雜質氣體向燈管 内擴散排放，致使燈管内雜質氣體的含量明顯增加，而本 發明吸氣裝置的合金筒或合金片表面剛剛開始啓動，從而 不能很快地吸收這些雜質氣體，由此造成了亮度的明顯下 降。隨後在不斷點燈至400小時左右，燈管内雜質氣體的 排放進入穩定的狀態，而本發明吸氣裝置的合金筒或合金 片開始明顯發揮作用，即大量吸氣，從而使燈管内的雜質 虱體含量又明顯下降。因此，燈管的表面亮度又明顯上 升，幾乎回復到燈管初期點燈時的亮度，這是常用的CCFl 所不能達到的。再繼續點燈時，燈f的表面亮度衰减進入 了％定、緩慢、幾乎呈直綫狀態的下降。這是由于燈管的 老化（例如螢光層的老化衰减、燈内汞的消耗反應）所造 成的，但是使用本發明吸氣裝置的燈管，其老化要比其他 常規的燈管緩慢得多。在連續點燈15萬小時時，本發明 的燈管，其表面亮度的衰减比其他燈管要减小1〇%左右。 這疋由于本發明的吸氣裝置在點燈過程中會不斷地吸收 燈官内的雜質氣體，從而使燈管内的雜質氣體保持在極低 1282574 的水平。同時，本發明的吸氣裝置在點燈過程中不會與燈 官内的汞蒸氣發生反應和吸收，因而能維持燈管内汞的含 里，這就疋燈官表面壳度衰减緩慢的原因。根據現有測量 資料推算，使用本發明吸氣裝置的燈管壽命可以達到5萬 小時以上。 除了 CCFL之外，日光燈作爲熱陰極螢光燈中的一 種，也是含水銀氣體放電管中常用的。以下就詳細地描述 使用本發明吸氣裝置的日光燈。 圖7示出了根據本發明第三實施例的家用熱陰極螢光 燈（俗稱日光燈）的結構示意圖。根據本發明的日光燈燈管 包括玻璃管殼2、塗覆在管殼2内壁上的螢光粉4、封入 吕内的氣體5(稀有氣體和汞蒸氣）、封裝在燈管端部的由鎢 、、糸製成的熱陰# 11 U及在㉟熱陰極導人端近燈絲處例如 用焊U的吸氣裝置7。在本例巾，該吸氣裝置7包括 一多孔合金片，在點燈過程中它會不斷地吸收日光燈管内 的雜質氣體，從而使日光燈管内氣體保持在極低的 X平门時，該吸氣裝置7在點燈過程中不會與日光燈管 内的汞蒸氣發生反應和吸收，因而能轉燈管内采的含 量’由此，延長日光燈管的壽命。 圖8不出的是根據本發明第四實施例的紫外綫管的結 構不心、圖。6包括玻璃官殼2、封人管内的氣體5(氮氮混 口氣體和汞療氣）、電極絲i以及在該電極絲上設置的吸氣 裝置7。在本例中，該吸氣裝置7包括—多孔合金筒，它 的工作原理與上述的多孔合金片相同，從而同樣起到吸氣 12 1282574 的作用。 以上的幾種含水銀氣體放電管，傳統上其電極都是内 置式的，在該電極上設置了本發明的吸氣裝置之後，可大 大延長放電管的使用壽命，尤其在CCFL中，該吸氣裝置 可以同時充當電極的角色，並發揮比常規電極更好的作 用。接下來，要討論一種電極外置式的含水銀氣體放電管。 圖9示出了根據本發明第五實施例的外置電極螢光燈 的結構示意圖。它包括玻璃管殼2、封入管内的氣體5(氖 氬混合氣體和汞蒸氣）、在燈管兩端的玻璃外壁上塗覆的導 電塗料9(也就是導電層）、與該導電塗料9連接的電源引入 環ίο、與導電層相連的在燈管内壁塗覆的色溫爲76〇〇〇κ 的螢光粉4以及在燈管兩端部用玻璃縮口卡住的兩個作爲 吸氣裝置的多孔合金筒7。 雖然在上述的實施例中，外置電極螢光燈中的吸氣裝 置是在燈管兩端部用玻璃縮口卡住的，但事實上，根據本 發明的外置電極螢光燈，其吸氣裝置可以用管殼内部的任 何部件固定在任何位置，比如在管殼的中部。 需要說明的是，以上的實施例3_5雖然都只用了多孔 合金筒或多孔合金片中的一種結構，但與CCFL 一樣，這 兩種結構可以進行互換。 除了以上的貫施例之外，本發明的吸氣裝置還可以設 置在咼壓汞燈、金屬鹵化物燈、水銀整流燈、水銀開關管 等含水銀蒸氣的燈管中，這裏不作一一介紹了。 爲了進一步說明本發明含水銀氣體放電管的特點，以 13 1282574 下列舉了各個實例。 實例1 直管型冷陰極螢光燈，燈管外徑2.6毫米，燈管内徑 2·〇宅米，燈管長度243毫米，使用鎢、鉬、鐵、鈷合金 5 筒焊接在鎢絲上作爲吸氣裝置（同時起到電極的作用），合 金筒成分範圍··鎢+鉬（10%〜40% )，鐵+鈷（60%〜 90% )。吸氣裝置封接在硼矽酸鹽玻璃（硬玻璃）管上，

are the most typical among many mercury-containing gas discharge tubes. Therefore, in the following, an embodiment of a cold cathode camping lamp incorporating the getter device of the present invention will first be described. 2 and 3 respectively show the structure of a cold cathode fluorescent lamp according to a first embodiment of the present invention and a two-dimensional schematic view of a portion of a porous alloy cylinder in the getter device. The cold cathode fluorescent tube according to the present invention comprises a glass envelope 2, a phosphor powder 4 coated on the inner wall of the envelope 2, a gas enclosed in the tube, and a wire 6 encased at the end of the tube and on the wire. A suction device 7 is provided, wherein both ends of the wire extend toward the inside of the tube and the outside of the tube, respectively. Different from the prior art cold cathode fluorescent lamp shown in FIG. 1 , the 15 S hair-cool cathode fluorescent lamp tube is additionally provided with an electrode, and the inclusion of at least one high temperature resistant metal and at least one iron family is adopted. A metal suction device 7 is used in place of the conventionally used nickel tube 3. The getter device 7 is composed of a porous metal cylinder and is placed on the electrode wire 6 inside the bulb by, for example, welding, so that it can function well as the electrode 20 at the same day temple which performs the suction operation. As one of the most critical components in the CCFL lamp, the electrode is responsible for the energization of the lamp, the emission of electrons, the establishment of a magnetic field, the heating of the lamp, and the like. Therefore, the performance of the lamp depends largely on the electrode material. However, at present, the nickel tube or the cylinder cylinder commonly used in CCFL lamps is drawn after being compressed by a large proportion of 1282574. It is a dense metal, so its surface area is limited by the inner diameter of the tube and the length of the electrode, resulting in practical work. The surface area is not large enough. At the same time, the melting point of metallic nickel is only about 1453 °C, so it is impossible to carry a large lamp current and a strong impact of electron current and ion current during lighting operation, thereby limiting the brightness of the lamp when the lamp is in operation. However, in the cold cathode fluorescent lamp using the getter device according to the present invention, the above problem does not exist. Since the getter device includes a smectite alloy or a porous alloy sheet having a porosity in the range of 5% to 96%, the surface area thereof is large, and therefore the absorbed electron-emitting material is also larger than the electrode of the conventional mercury-containing gas discharge tube. Increase several times. In this way, the number of electrons emitted from the surface of the getter device increases greatly as the power of the mercury-containing gas discharge tube increases, and the discharge tube can withstand a larger operating current while still being in a stable working state. . On the other hand, since the alloy of the getter device includes at least one metal resistant to high temperatures, the discharge tube can operate with a large current. Accordingly, the surface brightness thereof is also increased. Therefore, the gas discharge tube according to the present invention has a much higher photoelectric parameter than a conventional gas discharge tube. Of course, in the porous alloy cylinder or the porous alloy sheet of the getter device, substances other than the iron, cobalt, nickel, tungsten, molybdenum, button and sharp elements specified in the present invention may be doped as long as the content thereof is not More than 5% by weight, in other words, the total content of the metal elements specified in the present invention must be in the range of 50% to 100% of the total material of the getter device. Based on this, the components specified in the present invention contained in the getter device 7 can be selected from the following group of 1282574: 1 · tungsten or indium or tantalum or tantalum or tungsten + molybdenum or tungsten + tantalum or tungsten +钽 or #目+铌 or molybdenum + 钽 or 钽 + 铌 or tungsten + molybdenum + 钽 or tungsten + button + 铌 or cancer + in the eye + sharp or key + group + sharp or crane + face + group + sharp (70% ~9〇%) 5 / iron or nickel or cobalt or iron + nickel or iron + cobalt or nickel + cobalt or iron + nickel + cobalt (10% ~ 30%) 2 · crane or turn or group or sharp or crane + face Or crane + sharp or 嫣 + group or · + sharp or 锢 + group or group + sharp or crane + 锢 + group or crane + group + sharp or crane + turn + sharp or key + group + sharp or crane + face + group + sharp (40% ~ 70%) 1 〇 / iron or record or start or iron + record or iron + gu or iron + record + drill (30% ~ 60%) 3 · tungsten or molybdenum or tantalum or tantalum or tungsten + Molybdenum or tungsten + tantalum or tungsten + tantalum or molybdenum + sharp or pin + group or group + sharp or crane + 锢 + 钽 or crane + 钽 + 铌 or crane + molybdenum + sharp or Gu + group + sharp or 嫣 + indium + Group + sharp (10% ~ 40%) 15 / iron or nickel or start or iron + nickel or iron + start or nickel + start or iron + nickel + start (60% ~ 90%) 〇 made of the above ingredients The getter device is suitable for all mercury-containing gas discharge tubes according to the invention. The getter device 7 of the present invention adopts the composition of one of the above groups. On the one hand, it is a porous product, so the surface area is 2~20 times larger than that of the push-type nickel tube electrode of the same specification; on the other hand, it is very easy to absorb the surface coating which reduces the electron emission level, and makes it and the getter device. Firmly combined and released gradually and slowly during long-term work. Fig. 4 and Fig. 5 respectively show an enlarged perspective view of the structure of the cold cathode 1282574 fluorescent lamp tube and the portion of the porous alloy sheet in the getter device according to the second embodiment of the present invention. It differs from the cold cathode fluorescent lamp shown in Figs. 2 and 3 only in that the alloy cylinder 7 is replaced with a porous alloy sheet 8, so that this embodiment will not be described in detail. Figure 6 shows the life curve of a CCFL continuous lighting in accordance with the present invention. It can be seen from the change of the curve that in the initial stage of lighting (about 2 hours), the surface brightness of the lamp tube is significantly reduced (about 3% to 5%). This is because the glass, the fluorescent powder and the impurity gas in the electrode are diffused and discharged into the lamp tube at the beginning of the point k, so that the content of the impurity gas in the lamp tube is significantly increased, and the alloy cylinder or alloy piece of the getter device of the present invention is obtained. The surface has just started to start, so that these impurity gases cannot be absorbed quickly, thereby causing a significant drop in brightness. Then, after continuously lighting for about 400 hours, the discharge of the impurity gas in the lamp tube enters a stable state, and the alloy cylinder or the alloy piece of the getter device of the present invention starts to function obviously, that is, a large amount of suction, thereby making the inside of the lamp tube The impurity carcass content decreased significantly. Therefore, the surface brightness of the lamp tube rises remarkably, almost returning to the brightness of the lamp at the initial lighting, which is not possible with the conventional CCF1. When the lighting continues, the surface brightness of the lamp f is attenuated to a constant, slow, and almost linear state. This is due to the aging of the lamp (for example, the aging decay of the phosphor layer, the mercury consumption reaction in the lamp), but the lamp using the getter device of the present invention is much slower than other conventional lamps. . When the lamp is continuously lit for 150,000 hours, the lamp of the present invention has a surface luminance reduction of about 1% less than that of other lamps. Therefore, since the getter device of the present invention continuously absorbs the impurity gas in the lamp holder during the lighting process, the impurity gas in the lamp tube is maintained at an extremely low level of 1,282,574. At the same time, the getter device of the present invention does not react and absorb with the mercury vapor in the lamp officer during the lighting process, thereby maintaining the mercury content in the lamp tube, which is why the surface of the lamp lamp has a slow decay. . Based on the existing measurement data, the life of the lamp using the getter device of the present invention can reach 50,000 hours or more. In addition to CCFL, fluorescent lamps are one of the hot cathode fluorescent lamps and are commonly used in mercury-containing gas discharge tubes. The fluorescent lamp using the getter device of the present invention will be described in detail below. Fig. 7 is a view showing the structure of a domestic hot cathode fluorescent lamp (commonly referred to as a fluorescent lamp) according to a third embodiment of the present invention. The fluorescent lamp tube according to the present invention comprises a glass envelope 2, a phosphor powder 4 coated on the inner wall of the envelope 2, a gas 5 (rare gas and mercury vapor) enclosed in the anode, and tungsten encapsulated at the end of the tube. The hot cathode #11 U made by the crucible and the suction device 7 of the welding U are used, for example, at the vicinity of the 35 hot cathode. In the case of the present invention, the getter device 7 comprises a porous alloy sheet which continuously absorbs the impurity gas in the fluorescent tube during the lighting process, so that the gas in the fluorescent tube is kept at the extremely low X flat door, the suction The gas device 7 does not react and absorb with the mercury vapor in the fluorescent tube during the lighting process, and thus can recover the content of the fluorescent tube. Thus, the life of the fluorescent tube is prolonged. Fig. 8 is a view showing the structure of the ultraviolet tube according to the fourth embodiment of the present invention. 6 includes a glass envelope 2, a gas 5 (a nitrogen-nitrogen mixed gas and a mercury treatment gas) in the sealed tube, an electrode wire i, and a getter device 7 provided on the wire. In this example, the getter device 7 includes a porous alloy cylinder which operates in the same manner as the porous alloy sheet described above, thereby also functioning as a suction 12 1282574. The above several kinds of mercury-containing gas discharge tubes are conventionally built-in. After the air suction device of the present invention is disposed on the electrode, the service life of the discharge tube can be greatly extended, especially in the CCFL. The gas device can simultaneously act as an electrode and perform better than a conventional electrode. Next, an electrode-containing mercury-containing gas discharge tube is discussed. Fig. 9 is a view showing the structure of an external electrode fluorescent lamp in accordance with a fifth embodiment of the present invention. The utility model comprises a glass shell 2, a gas 5 enclosed in the tube (a mixture of helium and argon and mercury vapor), a conductive coating 9 (that is, a conductive layer) coated on the outer wall of the glass at both ends of the tube, and a power source connected to the conductive paint 9. Introducing a ring ίο, a phosphor powder 4 having a color temperature of 76 〇〇〇 κ coated on the inner wall of the tube connected to the conductive layer, and two holes as a gettering device which are stuck at the both ends of the tube with glass shrinkage Alloy cylinder 7. In the above embodiment, the getter device in the external electrode fluorescent lamp is caught by the glass shrinkage at both ends of the lamp tube, but in fact, the external electrode fluorescent lamp according to the present invention The suction device can be fixed in any position with any part inside the casing, such as in the middle of the casing.
