含水银的气体放电管及其吸气装置发明领域 FIELD OF THE INVENTION Field of the Invention

本发明涉及气体放电管，确切地说，涉及含水银的气体放电管及其吸气装置。背景技术 The present invention relates to a gas discharge tube, and more particularly, to a gas discharge tube containing mercury and a suction device thereof. Background technique

含水银的气体放电管，其种类非常丰富，有冷阴极荧光灯 (简称 CCFL)、直管型家用热阴极荧光灯 (也就是一般所说的日光灯）、高压汞灯、外置电极荧光灯管 (简称 EEFL灯管）、紫外线灯管、大功率水银整流管、水银开关管等。这些放电管的用途非常广泛，比如冷阴极荧光灯，它结构简洁、灯管细巧、表面亮度高、灯管温升小、使用寿命长，因此作为一种新颖的微型强光源，被广泛应用于液晶显示器、扫描仪、汽车仪表盘和微型广告灯箱等产品。 There are many types of gas discharge tubes containing mercury, including cold cathode fluorescent lamps (CCFL), straight tube domestic hot cathode fluorescent lamps (also known as fluorescent lamps), high-pressure mercury lamps, external electrode fluorescent lamps (EEFL for short) Lamps), UV lamps, high-power mercury rectifiers, mercury switch tubes, etc. These discharge tubes have a wide range of uses, such as cold cathode fluorescent lamps. They have a simple structure, a compact tube, a high surface brightness, a small temperature rise, and a long service life. Therefore, they are widely used as a novel miniature strong light source in liquid crystals. Monitors, scanners, car dashboards and miniature advertising light boxes.

在现有技术中，含水银的气体放电管，包括玻璃管壳、设置在玻璃管壳端部的电极、充入玻璃管壳内的一种或多种惰性气体和汞蒸气以及涂覆在管壳内壁 _t的荧光粉。图 1所示的就是作为典型含水银气体放电管的 CCFL灯管。如图所示，常规的 CCFL灯管包括：玻璃管壳 2、涂覆在管壳内壁上的荧光粉 4、封入管内的气本（例如氖氩混合气体和汞蒸气） 5以及设置在灯管两个端部的电极 1，该电极 1包封装在灯管端部的电极丝（钨丝、杜美丝或可伐合金丝） 6以及焊接在灯管内侧电极丝 6 上的镍管或镍筒 3。 In the prior art, a mercury-containing gas discharge tube includes a glass tube shell, an electrode disposed at an end of the glass tube shell, one or more inert gases and mercury vapors filled in the glass tube shell, and a coating on the tube. Phosphor for the inner wall of the shell_t. Figure 1 shows a CCFL lamp as a typical mercury-containing gas discharge tube. As shown in the figure, a conventional CCFL lamp tube includes: a glass tube shell 2, a fluorescent powder coated on the inner wall of the tube shell 4, an airbag enclosed in the tube (such as a neon-argon mixed gas and mercury vapor) 5 and a lamp tube Two end electrodes 1, the electrode 1 encapsulates the electrode wire (tungsten wire, Dumet wire or Kovar wire) 6 enclosed at the end of the lamp tube and the nickel tube or nickel welded to the electrode wire 6 inside the lamp tube Tube 3.

传统上不在含水银的气体放电管内设置吸气装置，因为该吸气装置可能会把该气体放电管内的水银一起吸收掉。但是，放电管所使用的玻璃和管内的荧光在长期点灯的工作过程中，会不断地排放出吸附的杂质，并从材料内部扩散排放出气体杂质和活性低熔点金属。因为没有吸气装置，这些气体杂质和活性金属进入放电管内部，将使放电管内气体的放电内阻增加，从而使放电管内的材料 "中毒" 而部分丧失其功能。这严重影响了含水银气体放电管的使用寿命。发明内容 It is not conventional to provide a getter device in a mercury-containing gas discharge tube, because the getter device may absorb the mercury in the gas discharge tube together. However, the glass used in the discharge tube and the fluorescence in the tube will continuously discharge the adsorbed impurities during the long-term lighting operation, and the gas impurities and active low melting point metals will be diffused and discharged from the inside of the material. Because there is no getter device, these gas impurities and active metals enter the interior of the discharge tube, which will increase the internal discharge resistance of the gas in the discharge tube, thereby "poisoning" the material in the discharge tube and partially losing its function. This seriously affects the service life of the mercury-containing gas discharge tube. Summary of the invention

本发明的目的就在于解决以上的技术问题，提供一种用于含水银气体放电管的吸气装置，它在不吸收水银的同时，能有效地吸收放电管内的杂质，从而可大大延长放电管的寿命。 The purpose of the present invention is to solve the above technical problems, and to provide an air suction device for a mercury-containing gas discharge tube, which can effectively absorb impurities in the discharge tube while not absorbing mercury, which can greatly delay Long discharge tube life.

本发明的另一个目的在于提供一种包含该吸气装置的含水银气体放电管。 Another object of the present invention is to provide a mercury-containing gas discharge tube including the getter device.

根据本发明的第一方面，提供一种用于含水银气体放电管的吸气装置，它包括设置在该含水银气体放电管内部的至少一个合金体（即，烧结的金属体），其中，所述的合金体由包括至少一种耐高温金属和至少一种铁族金属在内的材料制成。 According to a first aspect of the present invention, there is provided a getter device for a mercury-containing gas discharge tube, which includes at least one alloy body (ie, a sintered metal body) disposed inside the mercury-containing gas discharge tube, wherein, The alloy body is made of a material including at least one refractory metal and at least one iron group metal.

较佳地，可将该合金体设置为多孔合金筒或多孔合金片，该多孔的孔隙度可设置在 50 %- 96 %范围内。 Preferably, the alloy body can be set as a porous alloy cylinder or a porous alloy sheet, and the porosity of the porous body can be set within a range of 50% -96%.

铁族金属包括铁、钴和镍中的至少一种，耐高温金属包括钨、钼、钽和铌中的至少一种，它们的合计成分在 50%- 100 %的范围内。 The iron group metal includes at least one of iron, cobalt, and nickel, and the heat-resistant metal includes at least one of tungsten, molybdenum, tantalum, and niobium, and their total composition is in the range of 50% to 100%.

根据本发明的另一方面，提供一种包含上述吸气装置的含水银的气体放电管，它包括玻璃管壳、设置在玻璃管壳端部的电极丝、充入玻璃管壳内的一种或多种惰性气体和汞蒸气以及涂覆在管壳内壁上的荧光粉，其中，在所述电极丝上设置根据本发明的吸气装置。 According to another aspect of the present invention, there is provided a mercury-containing gas discharge tube containing the above-mentioned getter device, which includes a glass tube shell, an electrode wire provided at an end of the glass tube shell, and a type filled in the glass tube shell. Or more inert gas and mercury vapor and phosphor powder coated on the inner wall of the tube shell, wherein the getter device according to the present invention is provided on the electrode wire.

在这种情况下，放电管中的电极为内置，这种内置式电极的放电管可包括 CCFL、日光灯和高压汞灯等。 In this case, the electrodes in the discharge tube are built-in. The discharge tube of such a built-in electrode may include CCFL, fluorescent lamp, high-pressure mercury lamp, and the like.

根据本发明的另一方面，提供一种含水银的气体放电管，包括玻璃管壳、设置在玻璃管壳端部的电极丝、充入玻璃管壳内的一种或多种惰性气体和汞蒸气，其中，在所述电极丝上设置根据本发明的吸气装置。 According to another aspect of the present invention, a mercury-containing gas discharge tube is provided, which includes a glass tube shell, an electrode wire provided at an end of the glass tube shell, one or more inert gases and mercury filled in the glass tube shell. Vapor, wherein the getter device according to the present invention is provided on the electrode wire.

在这种情况下，放电管中的电极仍然为内置，该灯管包括直管型紫外线消毒用灯管。 In this case, the electrodes in the discharge tube are still built-in, and the tube includes a straight tube type ultraviolet disinfection tube.

根据本发明的另一个方面，提供一种含水银的气体放电管，它包括玻璃管壳、在该玻璃管壳内充入的一种或多种惰性气体和汞蒸气、在管壳端部的玻璃外部所涂覆的导电涂料、与该导电涂料连接的电源引入环以及在玻璃管壳内壁上所涂覆的荧光粉，其中，所述的气体放电管内部还包括至少一个根据本发明的吸气装置。 According to another aspect of the present invention, a mercury-containing gas discharge tube is provided, which includes a glass tube shell, one or more inert gases and mercury vapor filled in the glass tube shell, The conductive paint coated on the outside of the glass, the power supply lead-in ring connected to the conductive paint, and the fluorescent powder coated on the inner wall of the glass tube shell, wherein the inside of the gas discharge tube further comprises at least one absorber according to the present invention.气装置。 Gas device.

在这种情况下，放电管中的电极为外置，这种外置式电极的放电管可包括直管型外置电极的含水银气体放电灯，其中的吸气装置可在所述管壳端部用玻璃缩口卡住或设置在所述管壳的中部。 In this case, the electrodes in the discharge tube are external, and the discharge tube of such an external electrode may include a mercury-containing gas discharge lamp of a straight tube type external electrode, wherein the suction device may be at the end of the tube shell. The part is clamped or set in the middle of the tube shell with a glass neck.

在本发明中，因为使用了上述包括至少一种铁族金属的吸气装置，因而对氧、氮、一氧化碳、二氧化碳、水蒸气等杂质气体有极大的亲和力，并能与这些杂质气体很快地产生化合物，从而将它们吸收掉。与一般使用的吸气剂相比，本发明的合金体几乎不与汞蒸汽发生反应，从而也就不会影响灯管的发光均匀性和使用寿命。 In the present invention, since the above-mentioned getter device including at least one iron group metal is used, Impurities such as nitrogen, carbon monoxide, carbon dioxide, and water vapor have a great affinity, and can quickly generate compounds with these impurity gases, thereby absorbing them. Compared with the commonly used getter, the alloy body of the present invention hardly reacts with mercury vapor, and thus does not affect the uniformity of light emission and service life of the lamp tube.

同时，本发明的吸气装置还可以在吸收杂气的同时，充当电极的角色。因为该吸气装置包括了多孔合金筒或多孔合金片，其表面积很大，因此吸收的电子发射材料也比常规的含水银气体放电管的电极要增加几倍。这样一来，工作时该吸气装置表面发射出的电子数就随着该含水银气体放电管功率的增加而大量增加，放电管因此可以承受更大的工作电流而仍然处于稳定的工作状态下。另一方面，因为该吸气装置的合金中包括了至少一种耐高温的金属，所以该放电管的工作电流也增加了，相应地，其表面亮度也随之增加了。因而，根据本发明的气体放电管，其光电参数要比普通的气体放电管提高很多。 At the same time, the getter device of the present invention can also act as an electrode while absorbing impurities. Because the getter includes a porous alloy cylinder or a porous alloy sheet, and its surface area is large, the absorbed electron emitting material is also several times larger than that of a conventional mercury-containing gas discharge tube electrode. In this way, the number of electrons emitted from the surface of the getter device during operation increases greatly with the increase of the power of the mercury-containing gas discharge tube, so the discharge tube can withstand a larger working current and still be in a stable working state . On the other hand, because the alloy of the getter includes at least one high-temperature-resistant metal, the working current of the discharge tube also increases, and accordingly, the surface brightness also increases. Therefore, according to the gas discharge tube of the present invention, its photoelectric parameters are much higher than those of ordinary gas discharge tubes.

根据本发明的含水银气体放电管，能在不縮短工作寿命的前提下承受比常规的含水银气体放电管大一倍的工作电流，其表面亮度也有显著提高。而如果与常规的含水银气体放电管在相同的工作电流下工作，本发明的含水银气体放电管的寿命可提高 1〜1. 5倍。附图说明 The mercury-containing gas discharge tube according to the present invention can withstand a working current that is twice that of a conventional mercury-containing gas discharge tube without shortening the working life, and its surface brightness is also significantly improved. 5 倍。 And if with the conventional mercury-containing gas discharge tube working at the same operating current, the life of the mercury-containing gas discharge tube of the present invention can be increased by 1 ~ 1. 5 times.

在前文中已经提到，在众多含水银气体放电管中，冷阴极荧光灯 (CCFL)是最典型的。因此，在下文中，将首先介绍包含本发明吸气装置的冷阴极荧光灯的实施例。 As mentioned earlier, cold cathode fluorescent lamps (CCFL) are the most typical of many mercury-containing gas discharge tubes. Therefore, in the following, an embodiment of a cold cathode fluorescent lamp including a getter device of the present invention will be first introduced.

图 2和图 3分别示出了根据本发明第一实施例的冷阴极荧光灯管的结构及其吸气装置中多孔合金筒部分的放大立体示意图。根据本发明的冷阴极荧光灯管包括玻璃管壳 2、涂覆在管壳 2内壁上的荧光粉 4、封入管内的气体 5、封装在灯管端部的电极丝 6 以及在该电极丝上设置的吸气装置 7，其中，电极丝的两端分别向灯管内侧和灯管外侧延伸。 Fig. 2 and Fig. 3 respectively show enlarged structures of a cold-cathode fluorescent tube according to a first embodiment of the present invention and enlarged perspective views of a porous alloy tube portion in a getter device thereof. The cold-cathode fluorescent lamp tube according to the present invention includes a glass tube shell 2, a fluorescent powder 4 coated on the inner wall of the tube shell 2, a gas enclosed in the tube 5, an electrode wire 6 enclosed at an end of the lamp tube, and an electrode wire provided thereon. The inhaler 7 of the present invention, wherein both ends of the electrode wire extend to the inside of the lamp tube and the outside of the lamp tube, respectively.

与图 1所示的现有技术的冷阴极荧光灯管不同的是，在本发明的冷阴极荧光灯管中不再另外设置电极，而采用包含至少一种耐高温金属和至少一种铁族金属的吸气装置 7来代替常规使用的镍管 3。该吸气装置 7由一多孔合金筒构成，并通过例如焊接设置在灯管内侧的电极丝 6上，从而在完成吸气工作的同时，又可以很好地充当电极的角色。 Different from the cold cathode fluorescent lamp of the prior art shown in FIG. 1, the cold cathode fluorescent lamp of the present invention is not provided with an additional electrode, and an electrode containing at least one high temperature resistant metal and at least one iron group metal is used. A getter device 7 is used instead of the conventionally used nickel tube 3. The getter device 7 is composed of a porous alloy tube and is, for example, welded to the electrode wire 6 provided inside the lamp tube, so that it can play a good role as an electrode while completing the getter work.

作为 CCFL灯管中最关键部件之一的电极，承担着灯管通电、发射电子、建立磁场、加热灯管等诸多功能，因此灯管性能的优劣很大程度上取决于电极材料。但是目前，在 CCFL灯管中普遍使用的镍管或镍筒是经过大比例压缩后拉制而成的，属于致密金属，故其表面积受灯管内径和电极长度的限制，造成实际工作的表面积不够大。同时，金属镍的熔点仅为 1453Ό左右，所以在点灯工作时无法承受较大的灯管电流及较强的电子流和离子流的冲击，从而限制了灯管工作时表面亮度的提高。但是，在使用根据本发明吸气装置的冷阴极荧光灯管中，就不存在以上的问题了。 As one of the most critical components in CCFL lamps, the electrode bears many functions such as energizing the lamp, emitting electrons, establishing a magnetic field, and heating the lamp. Therefore, the performance of the lamp depends largely on the electrode material. However, at present, nickel tubes or nickel tubes commonly used in CCFL lamps are drawn after a large proportion of compression, which is a dense metal. Therefore, the surface area is limited by the inner diameter of the tube and the length of the electrode, which causes the actual working surface area. not big enough. At the same time, the melting point of metallic nickel is only about 1453 Ό, so it cannot withstand the impact of large lamp currents and strong electron and ion currents during lighting operation, which limits the improvement of surface brightness during lamp operation. However, in the cold cathode fluorescent lamp tube using the getter according to the present invention, the above problems do not exist.

因为该吸气装置包括了孔隙度在 50 %-96 %范围内的多孔合金筒或多孔合金片，其表面积很大，因此吸收的电子发射材料也比常规的含水银气体放电管的电极要增加几倍。这样一来，工作时该吸气装置表面发射出的电子数就随着该含水银气体放电管功率的增加而大量增加，放电管因此可以承受更大的工作电流而仍然处于稳定的工作状态下。另一方面，因为该吸气装置的合金中包括了至少一种耐高温的金属，所以该放电管可以较大的电流进行工作，相应地，其表面亮度也随之增加了。因而，根据本发明的气体放电管，其光电参数要比普通的气体放电管提高很多。当然，在该吸气装置的多孔合金筒或多孔合金片中，还可以惨杂除本发明所规定的铁、钴、镍、钨、钼、钽和铌七种元素之外的物质，只要其含量不超过 50 %，换言之，本发明所规定的金属元素的合计成分必须在所述吸气装置全部材料的 50 %〜100%的范围内。在此基础上，所述吸气装置 7中所含有的本发明所规定的成分可从下组中进行选择-Because the getter device includes a porous alloy cylinder or porous alloy sheet with a porosity in the range of 50% -96%, and its surface area is large, the absorbed electron emitting material is also increased compared with the electrode of a conventional mercury-containing gas discharge tube. Several times. In this way, the number of electrons emitted from the surface of the getter device during operation increases greatly with the increase of the power of the mercury-containing gas discharge tube, so the discharge tube can withstand a larger working current and still be in a stable working state. . On the other hand, because the alloy of the getter includes at least one high-temperature-resistant metal, the discharge tube can work with a relatively large current, and accordingly, the surface brightness is also increased accordingly. Therefore, the gas discharge tube according to the present invention has a much higher photoelectric parameter than the ordinary gas discharge tube. Of course, in the porous alloy cylinder or porous alloy sheet of the getter, substances other than the seven elements of iron, cobalt, nickel, tungsten, molybdenum, tantalum, and niobium specified in the present invention may be mixed, as long as they are The content does not exceed 50%. In other words, the total composition of the metal elements specified in the present invention must be within a range of 50% to 100% of the entire material of the getter device. On this basis, the components specified in the present invention contained in the suction device 7 can be selected from the following group −

1.钨或钼或钽或铌或钨 +钼或钨 +铌或钨 +钽或钼 +铌或钼 +钽或钽 +铌或钨 +钼 +钽或钨 +钽 +铌或钨 +钼 +铌或钼 +钽 +铌或钨 +钼 +钽 +铌（70 %〜90% ) /铁或镍或钴或铁 +镍或铁 +钴或镍 +钴或铁 +镍 +钴（10%〜30 % ) 1. Tungsten or molybdenum or tantalum or niobium or tungsten + molybdenum or tungsten + niobium or tungsten + tantalum or molybdenum + niobium or molybdenum + tantalum or tantalum + niobium or tungsten + molybdenum + tantalum or tungsten + tantalum + niobium or tungsten + molybdenum + Niobium or molybdenum + tantalum + niobium or tungsten + molybdenum + tantalum + niobium (70% ~ 90%) / iron or nickel or cobalt or iron + nickel or iron + cobalt or nickel + cobalt or iron + nickel + cobalt (10% ~ 30%)

2.钨或钼或钽或铌或钨 +钼或钨 +铌或钨 +钽或钼 +铌或钼 +钽或钽 +铌或钨 +钼 +钽或钨 +钽 +铌或钨 +钼 +铌或钼 +钽 +铌或钨 +钼 +·钽 +铌（40 %〜70% ) /铁或镍或钴或铁 +镍或铁 +钴或铁 +镍 +钴（30 %〜60% ) 2. Tungsten or molybdenum or tantalum or niobium or tungsten + molybdenum or tungsten + niobium or tungsten + tantalum or molybdenum + niobium or molybdenum + tantalum or tantalum + niobium or tungsten + molybdenum + tantalum or tungsten + tantalum + niobium or tungsten + molybdenum + Niobium or molybdenum + tantalum + niobium or tungsten + molybdenum + tantalum + niobium (40% to 70%) / iron or nickel or cobalt or iron + nickel or iron + cobalt or iron + nickel + cobalt (30% to 60%)

3.钨或钼或钽或铌或钨 +钼或钨 +铌或钨 +钽或钼 +铌或钼 +钽或钽 +铌或钨 +钼 +钽或钨 +钽 +铌或钨 +钼 +铌或钼 +钜 +铌或钨 +钼 +钽 +铌（10 %〜40% ) /铁或镍或钴或铁 +镍或铁 +钴或镍 +钴或铁 +镍 +钴（60%〜90% )。 3. Tungsten or molybdenum or tantalum or niobium or tungsten + molybdenum or tungsten + niobium or tungsten + tantalum or molybdenum + niobium or molybdenum + tantalum or tantalum + niobium or tungsten + molybdenum + tantalum or tungsten + tantalum + niobium or tungsten + molybdenum + Niobium or molybdenum + hafnium + niobium or tungsten + molybdenum + tantalum + niobium (10% ~ 40%) / iron or nickel or cobalt or iron + nickel or iron + cobalt or nickel + cobalt or iron + nickel + cobalt (60% ~ 90%).

由以上的成分所制成的吸气装置适用于根据本发明的所有含水银气体放电管。本发明的吸气装置 7采用以上所述之一组的成分形成。它一方面是一多孔制品，因而表面积比同样规格的致密镍管电极大 2〜20倍以上；另一方面，又极容易吸收降低电子发射能级的表面涂料，使其与吸气装置牢固结合，并在长期工作过程中使之逐步而缓慢地释放出来。 The getter made of the above components is suitable for all mercury-containing gas discharge tubes according to the present invention. The getter device 7 of the present invention is formed by using one of the components described above. On the one hand, it is a porous product, so its surface area is 2 to 20 times larger than that of a dense nickel tube electrode of the same specification; on the other hand, it is extremely easy to absorb surface coatings that reduce the electron emission level, making it firm with the getter. Combination, and gradually and slowly release it in the long-term work process.

图 4和图 5分别示出了根据本发明第二实施例的冷阴极荧光灯管的结构及其吸气装置中的多孔合金片部分的放大立体示意图。其与图 2和图 3所示的冷阴极荧光灯管的区别仅在于，用多孔合金片 8替代了合金筒 7，故对这个实施例不再详细描述。 Figs. 4 and 5 respectively show enlarged structures of a cold-cathode fluorescent lamp tube and a porous alloy sheet portion in a getter device according to a second embodiment of the present invention. It differs from the cold-cathode fluorescent lamp tube shown in Figs. 2 and 3 only in that the alloy tube 7 is replaced with a porous alloy sheet 8, so this embodiment will not be described in detail.

图 6示出的是根据本发明的 CCFL连续点灯的寿命曲线。从曲线的变化可以看出，在点灯的初期（约 200小时），灯管的表面亮度明显下降（约下降 3 %〜5% )。这是因为点灯初期灯管内玻璃、荧光粉、电极内的杂质气体向灯管内扩散排放，致使灯管内杂质气体的含量明显增加，而本发明吸气装置的合金筒或合金片表面刚刚开始激活，从而不能很快地吸收这些杂质气体，由此造成了亮度的明显下降。随后在不断点灯至 400小时左右，灯管内杂质气体的排放进入稳定的状态，而本发明吸气装置的合金筒或合金片开始明显发挥作用，即大量吸气，从而使灯管内的杂质气体含量又明显下降。因此，灯管的表面亮度又明显上升，几乎回复到灯管初期点灯时的亮度，这是常用的 CCFL所不能达到的。再继续点灯时，灯管的表面亮度衰减进入了稳定、缓慢、几乎呈直线状态的下降。这是由于灯管的老化（例如荧光层的老化衰减、灯内汞的消耗反应）所造成的，但是使用本发明吸气装置的灯管，其老化要比其它常规的灯管缓慢得多。在连续点灯 1. 5万小时时，本发明的灯管，其表面亮度的衰减比其它灯管要减小 10 %左右。这是由于本发明的吸气装置在点灯过程中会不断地吸收灯管内的杂质气体，从而使灯管内的杂质气体保持在极低的水平。同时，本发明的吸气装置在点灯过程中不会与灯管内的汞蒸气发生反应和吸收，因而能维持灯管内汞的含量，这就是灯管表面亮度衰减缓慢的原因。根据现有测量数据推算，使用本发明吸气装置的灯管寿命可以达到 5万小时以上。 FIG. 6 shows a life curve of a CCFL continuous lighting according to the present invention. From the change of the curve, it can be seen that at the initial stage of lighting (about 200 hours), the surface brightness of the lamp tube is significantly reduced (about 3% to 5%). This is because the impurity gases in the glass, fluorescent powder, and electrodes in the lamp tube are diffused and discharged into the lamp tube during the initial lighting period, which causes the content of the impurity gases in the lamp tube to increase significantly. The surface of the alloy cylinder or alloy sheet of the getter device of the present invention has just Began to activate, so that these impurity gases could not be absorbed quickly, which caused a significant decrease in brightness. Subsequently, when the light is continuously turned on for about 400 hours, the discharge of the impurity gas in the lamp tube enters a stable state, and the alloy cylinder or alloy sheet of the suction device of the present invention starts to play a significant role, that is, a large amount of air is sucked in, thereby causing impurities in the lamp tube Gas containing The amount has dropped significantly. Therefore, the brightness of the surface of the lamp tube rises significantly, almost returning to the brightness when the lamp was initially lit, which cannot be achieved by the commonly used CCFL. When lighting is continued, the surface brightness of the lamp tube decays into a steady, slow, almost linear decline. This is caused by the aging of the lamp tube (such as the aging degradation of the fluorescent layer and the mercury consumption reaction in the lamp), but the lamp tube using the suction device of the present invention has a much slower aging than other conventional lamp tubes. When the lamp is continuously lit for 15,000 hours, the attenuation of the surface brightness of the lamp tube of the present invention is reduced by about 10% compared with other lamp tubes. This is because the suction device of the present invention continuously absorbs the impurity gas in the lamp tube during the lighting process, thereby keeping the impurity gas in the lamp tube at an extremely low level. At the same time, the inhalation device of the present invention does not react and absorb with the mercury vapor in the lamp tube during the lighting process, so it can maintain the mercury content in the lamp tube, which is why the brightness of the surface of the lamp tube decays slowly. According to the estimation of the existing measurement data, the life of the lamp tube using the inhalation device of the present invention can reach more than 50,000 hours.

除了 CCFL之外，日光灯作为热阴极荧光灯中的一种，也是含水银气体放电管中常用的。以下就详细地描述使用本发明吸气装置的日光灯。 In addition to CCFLs, fluorescent lamps are one of the hot cathode fluorescent lamps and are also commonly used in mercury-containing gas discharge tubes. The fluorescent lamp using the suction device of the present invention is described in detail below.

图 7示出了根据本发明第三实施例的家用热阴极荧光灯 (俗称日光灯）的结构示意图。根据本发明的日光灯灯管包括玻璃管壳 2、涂覆在管壳 2内壁上的荧光粉 4、封入管内的气体 5 (稀有气体和汞蒸气）、封装在灯管端部的由钨丝制成的热阴极 11 以及在该热阴极导入端近灯丝处例如用焊接设置的吸气装置 7。在本例中，该吸气装置 7包括一多孔合金片，在点灯过程中它会不断地吸收日光灯管内的杂质气体，从而使日光灯管内的杂质气体保持在极低的水平。同时，该吸气装置 7在点灯过程中不会与日光灯管内的汞蒸气发生反应和吸收，因而能维持灯管内汞的含量，由此，延长日光灯管的寿命。 Fig. 7 is a schematic diagram showing the structure of a domestic hot cathode fluorescent lamp (commonly known as a fluorescent lamp) according to a third embodiment of the present invention. A fluorescent tube according to the present invention includes a glass tube housing 2, a phosphor 4 coated on the inner wall of the tube housing 2, a gas 5 (a rare gas and a mercury vapor) enclosed in the tube, and a tungsten wire packaged at the end of the tube. The resulting hot cathode 11 and a getter device 7 provided near the filament at the lead-in end of the hot cathode, for example, by welding. In this example, the getter device 7 includes a porous alloy sheet. During the lighting process, it continuously absorbs the impurity gas in the fluorescent tube, thereby keeping the impurity gas in the fluorescent tube at an extremely low level. At the same time, the suction device 7 does not react and absorb with the mercury vapor in the fluorescent tube during the lighting process, so it can maintain the mercury content in the fluorescent tube, thereby extending the life of the fluorescent tube.

图 8示出的是根据本发明第四实施例的紫外线管的结构示意图。它包括玻璃管壳 2、封入管内的气体 5 (氖氩混合气体和汞蒸气）、电极丝 1以及在该电极丝上设置的吸气装置 7。在本例中，该吸气装置 7包括一多孔合金筒，它的工作原理与上述的多孔合金片相同，从而同样起到吸气的作用。 FIG. 8 is a schematic structural diagram of an ultraviolet tube according to a fourth embodiment of the present invention. It includes a glass tube shell 2, a gas 5 (neon-argon mixed gas and mercury vapor) enclosed in a tube, an electrode wire 1 and a getter device 7 provided on the electrode wire.

After the getter device of the present invention is provided on the electrode, the service life of the discharge tube can be greatly extended, especially in CCFL, the The gas device can simultaneously function as an electrode and play a better role than a conventional electrode. Next, a mercury-containing gas discharge tube with an external electrode is discussed.

It includes a glass tube shell 2, a gas enclosed in the tube 5 (neon-argon mixed gas and mercury vapor), and a coating on the outer glass wall The color temperature of the coated conductive coating 9 (ie, the conductive layer), the power supply introduction ring 10 connected to the conductive coating 9, and the conductive layer and the inner wall of the lamp tube is 7600. K's phosphor 4 and two porous alloy cylinders 7 as suction devices which are clamped with glass necks at both ends of the tube.

虽然在上述的实施例中，外置电极荧光灯中的吸气装置是在灯管两端部用玻璃缩口卡住的，但事实上，根据本发明的外置电极荧光灯，其吸气装置可以用管壳内部的任何部件固定在任何位置，比如在管壳的中部。 Although in the above-mentioned embodiment, the suction device of the external electrode fluorescent lamp is clamped with glass necks at both ends of the lamp tube, in fact, according to the external electrode fluorescent lamp of the present invention, the suction device can Use any part inside the tube shell to fix it in any position, such as the middle of the tube shell.

需要说明的是，以上的实施例 3-5虽然都只用了多孔合金筒或多孔合金片中的一种结构，但与 CCFL—样，这两种结构可以进行互换。 It should be noted that although the above embodiments 3-5 only use one structure of the porous alloy cylinder or the porous alloy sheet, the two structures can be interchanged with the CCFL.

除了以上的实施例之外，本发明的吸气装置还可以设置在高压汞灯、金属卤化物灯、水银整流灯、水银开关管等含水银蒸气的灯管中，这里不作一一介绍了。 In addition to the above embodiments, the getter device of the present invention may also be provided in lamps containing mercury vapor, such as high-pressure mercury lamps, metal halide lamps, mercury rectifier lamps, and mercury switch tubes, which are not described here one by one.
