Abstract
A novel cathode of a fluorescent lamp is composed of flat filaments of T1-T2 tube diameter, V type filaments of 1.5 times of T3-T4 tube diameter, U type filaments of 2.5 times of T5 tube diameter or S type filaments of 3 times of tube diameter, the filaments are made into double spirals, three spirals or main and auxiliary type three spirals by tungsten filaments, are dip coated or electrophoresised with ternary carbonate electric powder on the surface, are exhausted to electrically decompose into oxide electrodes, under the condition that the lamp tube is used for driving an electronic ballast, a hot cathode wiring method without filaments can be adopted. The invention not only solves the problem that the tube diameter below T3 is not easy to seal and assemble, but also solves the key problem of making the T1 hot cathode fluorescent lamp without the method, and solves the problem that the electric powder storage is not enough after thinning the tube diameter of the fluorescent lamp. The invention is useful for improving switching characteristic of the fluorescent lamp, increasing lumen maintenance rate and prolonging light decline. The test proves that fifty present to one time of life service of the one lamp tube can be extended.
Description
Technical field
The present invention relates to electricity field, relate in particular to lighting apparatus, particularly fluorescent lamp, concrete is novel cathode of fluorescent lamp.
Background technology
Now in the technology, make negative electrode as general lighting is continued to use a paperback with the fluorescent lamp commercial applications over nearly 70 years filament always, (1 T=1/8 inch, 3.175mm) age in vogue does not feel that also the bad assembling of this silk or electronics powder reserves are not enough at T12, T10.Invention and application from the seventies triphosphor Fluorescent Powder in last century, the fluorescent lamp caliber refine to T3, T2 from T8, T5 always, in the fluorescent tube production process, obviously feel this flat silk be bad and seal, assemble that the electronics powder reserves that are coated in the filament surface also feel not enough.In fact " one " font paperback method of this root filament has seriously restricted the fluorescent lamp quality and the lifting in life-span, even crisis is to the survival and development of this lamp kind of fluorescent lamp.
Summary of the invention
The purpose of this invention is to provide novel cathode of fluorescent lamp, described this novel cathode of fluorescent lamp will solve the bad not enough problem of electronics powder reserves of sealing, assembling and being coated in the filament surface of " one " font filament paperback in the fluorescent tube production process.
Novel cathode of fluorescent lamp of the present invention, constitute by 2.5 times of " U " type silks of 1.5 times of " V " type silks of the raw silk rings of T1-T2 caliber, T3～T4 caliber, T5 caliber or 3 times of " S " type filaments of the above caliber of T8, filament turns to double helix or triple helical by tungsten filament, and exhaust energising heating and decomposition becomes efficient oxidation thing electrode.The raw silk rings negative electrode of described T1～T2 caliber is vertically arranged, described vertical installation method is one section quartz glass tube of cover or a titanium dioxide aluminum pipe on an inner guide wire, the prior filament of the good electronics powder of dip-coating is sleeved on quartz glass tube or aluminium dioxide tube outside, again filament sealed exhaust energising heating and decomposition with two inner guide wires that one is long and the other is short are wired after firmly end to end again; 1.5 times of " V " type wire cathodes of described T3～T4 caliber, be when designing, to extend an original paperback filament more than 1.5 times, on stem stem, increase a molybdenum hook during assembling and make filament support, promptly the negative electrode of a paperback filament has been changed system into the negative electrode of " V " type silk paperback, when dip-coating or electrophoretic electronic powder two sections branches of " V " type are done twice and carry out sealing again afterwards, exhaust energising heating and decomposition; 2.5 times of " U " type wire cathodes of described T5 caliber, be when designing, to extend an original paperback filament more than 2.5 times, during assembling on stem stem two molybdenum hooks of equidistant increase make filament support, promptly the negative electrode of a paperback filament has been changed system into a negative electrode that equidistantly separates " U " type silk paperback of three sections, three sections of dip-coating or electrophoretic electronic powder time-divisions are sealed exhaust energising heating and decomposition after carrying out for three times again; 3 times of " S " type filament cathodes of the above caliber of described T8, be that an original paperback filament is extended 3 times when designing, on three seal wire stem stems, increase a molybdenum hook during assembling again and make filament support, a filament is divided into three sections, the first segment filament head and first inner guide wire are wired firmly, the first segment filament tail is connected naturally with the second segment filament head, support by a molybdenum hook support, the second segment filament tail is connected naturally with the 3rd segment filament head and is wired firmly with second inner guide wire, the 3rd segment filament tail and the 3rd inner guide wire are wired firmly, first section with second segment filament be " V " font, parallel assembling, the 3rd segment filament tiltedly loads and fits over first, below during two segment filaments lean on, three sections of dip-coating or electrophoretic electronic powder time-divisions are sealed exhaust energising heating and decomposition after carrying out for three times again.
Further, the raw silk rings of described T1～T2 caliber, 1.5 times of " V " type silks of T3～T4 caliber, 2.5 times " U " silk of T5 caliber, 3 times of " S " type filament cathodes of the above caliber of T8, under the situation that fluorescent tube drives with electric ballast, all adopt no filament hot cathode mode of connection, soon filament end to end or head, middle and end connect together.
Further, under the situation of 3 times of " S " type filament cathode fluorescent tubes with the inductance ballast driven of the above caliber of described T8, first and second outer seal wire connects together and is a binding post of fluorescent tube one end, and the 3rd outer seal wire is another binding post.
Further, the raw silk rings of described T1～T2 caliber, 1.5 " times V " type silk of T3～T4 caliber, 2.5 times of " U " type silks of T5 caliber or 3 times of " S " type filaments of the above caliber of T8 end to end or head, middle and end when connecting together, Q during its filament design
200Mg get maximum, the filament cold resistance is got minimum value.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention is under the Filament-free heated cathode fluorescent lamp guide of theory, one tubes is by the function of utilization filament and negative electrode coenosarc on the exhaust car, make the triplex carbonate electronics powder of cathode-coated decompose, give vent to anger and activate to filament energising heating, form oxide electrode and just stop using the filament function of negative electrode afterwards, so when a target of initial design one tubes on the cathode function of complete meaning, tungsten filament is the Base Metal and the carrier of negative electrode, its Q
200The value of mg be that trend is maximum, the value of the Design of length of negative electrode also is to tend to the longest, the reserves of final a pair of cathode electronics powder are to obtain maximum.Therefore, the present invention had both solved the bad problem of sealing assembling of T3～T2 caliber hot-cathode fluorescent lamp, also solved the key issue that to make T1 caliber thermal cathode fluorescent tube, especially electronics powder reserves are not enough after having solved the refinement of fluorescent lamp caliber, negative electrode is not good and cathodic sputtering is serious by the wall switch performance, early stage blackhead, light decay is big, the root problem that the life-span is short.
Purpose of the present invention, feature and advantage will be elaborated by embodiment.
