Description
Technical field:
The utility model relates to a kind of alloy electrode, belongs to the part field of electron-optical arrangement.
Background technology:
CCFL (Cold Cathode Fluorescent Lamp-CCFL) is mainly used in the backlight of LCD liquid crystal display notebook computer, console display, color TV, instrument, instrument, also extensively is disposed at the light source of scanner, facsimile machine, photocopier; Be applied to use and applications such as high-rise building residence imports and exports safety direction board, emergency light, indoor senior artistic decoration, night trail guide, solar lawn street lamp, the high pressure of configuration, high frequency electric source make fluorescent tube have light intensity, even, soft, characteristics such as do not glimmer.Because its power saving, brightness is big, the life-span is long, volume is little, can make multiple shape, so demand is enlarging day by day.
Present CCFL electrode structure is hollow nickel cup electrode, and hollow nickel cup connects the wire of certain coefficient of expansion, and this wire is that electrode and glass tube merge the coupling part, decides the coefficient of expansion other end wiry and is connected with plain conductor.In view of the present situation of CCFL electrode, there are some problems in the CCFL fluorescent tube on production technology:
1. current C CFL lighting tube production technology is the amalgamation gold bar of packing in the lamp tube electrode outer end, after the mercury bar discharges mercury, need add the glass tube of thermal cut-out dress mercury bar, produce venting, spread in fluorescent tube, vacuum degree and argon filling purity in the influence pipe cause the fluorescent tube photoelectric properties to descend.
2. existing CCFL lamp tube ends is equipped with hollow nickel cup electrode, and down, can't eliminate in working order by the foreign gas that metal electrode produces in fluorescent material, the glass tube for fluorescent tube.
3. after using mercury bar technology to inject mercury, during CCFL work, fluorescent material, glass tube can absorbed portion mercury, and the mercury of minimizing can not get replenishing, and makes the fluorescent tube light decay become big, has influenced the life-span of fluorescent tube.
Thereby keeping the generation of vacuum degree, purity inert gas, minimizing foreign gas in the fluorescent tube, also can in time replenishing mercury is the key that improves the CCFL overall performance, as the electrode of critical component, in the solution of the problems referred to above, important function is arranged.
The utility model content:
The purpose of this utility model is to provide a kind of alloy electrode.
Described alloy electrode, by release mercury alloy, inhale one or both or three kinds of alloy components of making, metal jackets in mercury alloy and the getter alloy, decide coefficient of expansion alloy silk, plain conductor is formed, described alloy component places in the metal jacket, an end of deciding coefficient of expansion alloy silk is connected with the metal jacket, and the other end of deciding coefficient of expansion alloy silk is connected with plain conductor.
Metal jacket in this alloy electrode is the tubular of a both ends open or an end opening or the cup-shaped of an end opening; The cross section of metal jacket is circle, rectangle or polygon.
Alloy component in the above-mentioned alloy electrode is bulk or strip.In the practical application, preferred bulk alloy parts are cylindric or circular.When using the strip alloy component, preferred strip alloy component is that a spiral is thread.
The metal jacket must meet the electrovacuum instructions for use, vertically open seam or seamless can be arranged, and length is 2～6mm.The metal sheath material can be alloys such as stainless steel, nickel, molybdenum, tantalum, titanium, nickel-clad iron.
Release mercury alloy, for titanium amalgamation bronze, zirconium alloy, zirconium Al rare earth alloy, zirconium lead amalgam powder is one kind of or the mixed-powder of several arbitrary proportions, the particle size average is less than or equal to 100 orders.
Getter alloy is titanium zirconium rare earth alloy, zirconium alloy, zirconium Al rare earth alloy, zirconium vanadium iron nickel alloy, and its particle size average is less than or equal to 120 orders, can be the mixture of above-mentioned single or multiple arbitrary proportion alloy.
Inhale mercury alloy, be one or more the arbitrary proportion mixed-powders formed in indium, tin, lead, bismuth, calcium, the aluminium.
In the practical application, can be as required, select one or both or three kinds in above-mentioned three kinds of alloys, m ut f pulv, release mercury alloy: getter alloy: the weight ratio of inhaling between the mercury alloy is 1～1.5: 1～0.2: 0.1～0.02, and the powder pressure forms piece or strip places in the metal jacket; Alloy component also can be made as wire and place in the metal jacket, fixes by engaging or elastic deformation.During filling, should satisfy alloy powder and be fixed in the jacket, and should not be full of the inner space of canning tube, must leave 10～80% space, so that the emission of the electronics during lamp works.
The metal jacket is weldingly connected with an end of deciding coefficient of expansion alloy silk, and the other end of deciding coefficient of expansion alloy silk links to each other with welded wire.As shown in Figure 1.
Decide coefficient of expansion alloy silk and have the identical coefficient of expansion with the glass material of CCFL fluorescent tube.
The utlity model has following advantage:
1. owing to containing, alloy electrode described in the utility model releases mercury alloy, can discharge the mercury of capacity behind the employing coreless induction furnace induction heating, cooperate and inhale mercury alloy, discharge excessive mercury and also can be absorbed by the suction mercury alloy, so can release mercury by accurate quantification, the stable state when guaranteeing CCFL work.
2. used up mercury during lamp works can be emitted by inhaling the mercury that mercury alloy absorbed, and the mercury in the fluorescent tube is replenished, and can keep the operating state of fluorescent tube the best.
3. because the operation of release mercury is to carry out in fluorescent tube, the complexity in the time of can reducing to make on the one hand shortens Production Time, can also reduce the unnecessary mercurous discarded object that production process produces on the other hand.
Fluorescent tube quit work and lamp tube service life at the end, mercury vapour is absorbed by low-melting-point metal and solidifies in the fluorescent tube, scatters thereby eliminated liquid mercury, has improved the difficulty of recovery operation, helps environmental protection.
5. include getter alloy in the electrode described in the utility model, so fluorescent tube in working order down, electrode can absorb oxygen, nitrogen, hydrogen, carbide isoreactivity gas residual or that produce in the fluorescent tube, the lamp works time is long more, the electrode getter action is obvious more, thereby can guarantee that lamp works is stable, high briliancy, long-life, be far superior to not have the CCFL fluorescent tube of getter alloy.
