Triple-coil filament has played enormous function at fluorescent lamp in the development of compact energy-saving fluorescent lamp.The triple-coil filament that adopt present domestic market mainly comprises monofilament triple-coil filament, cable triple-coil filament, master-slave type three-helix filament etc., wherein master-slave type three-helix is used more extensive, compare with preceding two class filaments, the main and auxiliary type filament has the advantage of configuration aspects, and the sputter of electronics powder is few, for the life-span that prolongs electricity-saving lamp, avoid the early stage yellow black obvious effects that has; But because major-minor tungsten filament internal-external temperature difference is bigger, between auxilliary silk and the main silk and secondary twine a large amount of electronics powder that the body core is being wrapped up in, when exhaust, activate difficultly, adopt such filament that the exhaust air technique and the Design of Digital Ballast of fluorescent tube manufacture process are had relatively high expectations.
Summary of the invention
The utility model provides that a kind of electron ion rational in infrastructure, anti-bombardment ability is strong, electric heating transforms the usefulness height, filament thermal radiation area is big, negative electrode decomposes novel two main filament three-helical filaments effective, long service life.
A kind of two main filament three-helical filament, comprise by once twining body and twine the filament main body that forms and the filament pin at filament main body two ends through twice spiral, wherein, described once twine body by two parallel near main tungsten filament and the unidirectional auxilliary tungsten filament that evenly closely is spirally wound on two main tungsten filaments form.
The filament main body is twined body by secondary and is formed through the one-way spiral winding, and the centre bore of filament main body is circular, and can twine body by secondary is that circular steel core pin spiral winding forms around cross section, extracts the steel core pin at last out and gets final product; Secondary winding body forms through the one-way spiral winding by once twining body, and the centre bore that secondary twines body also is circular, can be that circular molybdenum heart yearn spiral winding forms around cross section by once twining body equally, removes the molybdenum heart yearn at last and gets final product.The diameter of molybdenum heart yearn can be determined according to actual needs, is generally 2～3 times of winding body screw diameter to be wound, the winding that is beneficial to twine body.The helix length of filament main body can determine that the length of filament pin can determine according to actual needs that the centre bore of filament pin is circular according to the size of actual tube diameter.
Two main tungsten filaments are made up of equal diameters or the first main tungsten filament that does not wait and the second main tungsten filament, according to the size of the first main tungsten filament and the second main tungsten filament diameter, auxilliary tungsten filament is spirally wound on to form on the first main tungsten filament and the second main tungsten filament with pyriform or ellipse and once twines body; The winding of auxilliary tungsten filament effectively protects the first main tungsten filament and the second main tungsten filament to avoid its surface damage; Adopt two main tungsten filaments simultaneously, the surface area of the tungsten filament that increases, the reserves of electronics powder have been increased, further prolonged the useful life of electricity-saving lamp, made simultaneously that tungsten filament is widely distributed evenly, electric heating transforms that usefulness improves, the increase of filament thermal radiation area makes that the electronics powder is heated evenly, cathodal closing decomposes evenly fast, cathode electronics powder decomposition activation effect is effectively promoted.
Two main filament three-helical filament manufacture method of the present utility model is: will assist at first that tungsten filament is unidirectional evenly closely to be wound on the heart yearn group that the first main tungsten filament and the second main tungsten filament form, once twined body, wherein the first main tungsten filament and the second main tungsten filament be parallel to each other and a side mutually near; Then filament is once twined body and be wound on the molybdenum heart yearn, obtain secondary and twine body; The secondary winding body that obtains is carried out spiral winding for the third time around the steel core pin make the filament main body, and respectively stay the identical secondary of a segment length to twine body, obtain two main filament three-helical filaments through subsequent treatment as filament pin at filament main body two ends.
The beneficial effects of the utility model are embodied in: selection will assist tungsten filament resemble a pear in shape shape or elliptical shape spiral surrounding two near main tungsten filament on structure; effectively protected main tungsten filament to avoid its surface damage; the mechanical strength and the toughness of main tungsten filament have better been strengthened; improved the finished product rate; make tungsten filament and the adhesion of electronics powder firmly be difficult for dropping simultaneously; more anti-electron ion bombardment, tungsten filament is widely distributed evenly in the filament; electric heating transforms usefulness and improves; filament thermal radiation area increases is heated evenly the electronics powder; cathodal closing decomposes evenly fast; cathode electronics powder decomposition activation effect is effectively promoted.
