Description
Technical field
The utility model relates to a kind of filamentray structure of electricity-saving lamp, particularly a kind of major-minor type three-thread three-spiral filament for energy-saving lamp.
Background technology
Power saving fluorescent lamp is present most important artificial light sources, extensively is used in the whole world.Especially in industry and commercial lighting field, the ideal that the diversity of its high-effect, good light output, color and long useful life make it to become in the above-mentioned lighting field is selected.The life-span of power saving fluorescent lamp is after the reason that defective workmanships such as having got rid of wick column bursts, gas leakage causes, concerning the power saving fluorescent lamp of technology compliant, its life-span is depended on because of mercury runs out of the fluorescent tube inefficacy that causes and launches thermionic cathode life, and wherein most important factor is exactly a cathode life.The life-span of power saving fluorescent lamp negative electrode depends primarily on the ability of the anti-ion bombardment of its filament and the ability of quick excitation electron, when filament can not heat up or heat up the electron deficiency that slowly causes cathode emission to light fluorescent lamp or when exhausting attached to the electronics powder on the filament, filament produces fracture of wire because of being subjected to ion bombardment, the life-span of the fluorescent lamp knot that promptly comes to an end.Therefore, how to strengthen the ability of the anti-ion bombardment of filament, improve the intensification usefulness of filament and the storage capacity of raising electronics powder and become the prolongation filament and the key in power saving fluorescent lamp life-span.
Present energy-saving lamp filament mainly adopts the master-slave type three-helix structure, is promptly twined by a main tungsten filament and three spirals of an auxilliary tungsten filament and forms the master-slave type three-helix structure.Though the filament bombardment resistance of this structure can be also better, the storage capacity of electronics powder is also more, because production efficiency is low, and disconnected easily auxilliary silk, exhaust efficiency is low, influences the reliability of fluorescent tube.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of longer service life, the faster and difficult generation fracture of wire of filament winding speed, strong, the shorter major-minor type three-thread three-spiral filament for energy-saving lamp of heating-up time of higher, the anti-bombardment ability of electronics powder reserves.
For solving the problems of the technologies described above the technical solution of the utility model: major-minor type three-thread three-spiral filament for energy-saving lamp.It by the filament secondary twine body in the shape of a spiral the shape coiling form, the filament secondary twine body by filament once twine body in the shape of a spiral the shape coiling form, filament once twine body by main tungsten filament and be spirally wrapped around on the main tungsten filament near the auxilliary tungsten filament coiling more than three or three form.
Above-mentioned major-minor type three-thread three-spiral filament for energy-saving lamp, specifically, filament once twine body be by main tungsten filament and be spirally wrapped around on the main tungsten filament near three auxilliary tungsten filament coilings form.
Aforesaid major-minor type three-thread three-spiral filament for energy-saving lamp, filament once twine body also can be by main tungsten filament and be spirally wrapped around on the main tungsten filament near four auxilliary tungsten filament coilings form.
Aforesaid major-minor type three-thread three-spiral filament for energy-saving lamp, filament once twine body can also be by main tungsten filament and be spirally wrapped around on the main tungsten filament near five auxilliary tungsten filament coilings form.
The beneficial effects of the utility model: the utility model adopts at least three auxilliary tungsten filaments to carry out three-section type spiral winding side by side synchronously, can increase the storage capacity of cathode electronics powder and firmly, electronics powder reserves are higher, be easier to the active electron powder, shortened filament preheating time, heating-up time is shorter, improve the bombardment resistance energy of filament greatly, anti-bombardment ability is stronger, avoid turning black in early days phenomenon, the contact area of electronics powder when also having increased the filament heating power greatly is heated evenly fluorescent tube electronics powder in the exhaust decomposable process, and cathode activation is easier, energising starts faster, can significantly improve the useful life of fluorescent tube, its life-span can reach 10000 hours, and energy-saving effect can reach 80%; And under the identical situation of gross power, owing to adopt three auxilliary tungsten filaments to twine side by side, carefully more a lot of than the diameter that adopts an auxilliary tungsten filament to twine the auxilliary tungsten filament that is adopted, production cost reduces (three thin tungsten filaments are equivalent to a thick tungsten filamen) greatly, not only speed of wrap is faster, wrapping wire efficient is higher (to be needed on every centimeter length when adopting an auxilliary tungsten filament to twine originally around 240～250 circles, only need be on every centimeter length when adopting three auxilliary tungsten filaments to twine now around 80 circles, wrapping wire efficient can improve 60%), and when twining, be difficult for taking place fracture of wire, the product percent of pass height, make fluorescent tube after reliability higher.And the sectional area of the auxilliary tungsten filament of sectional area ratio that three auxilliary tungsten filaments are added up wants big, and (when adopting an auxilliary tungsten filament with a main tungsten filament originally, about 10% electric current is by assisting tungsten filament thereby increased the overcurrent of auxilliary tungsten filament; After adopting three auxilliary tungsten filaments side by side now, can bring up to more than 30% by the electric current of auxilliary tungsten filament) not only intensification is faster, and the load that has alleviated main tungsten filament, has prolonged the useful life of main tungsten filament.The utility model is applicable to various fluorescent lamps, is a kind of novelty, high-quality, efficient, long-life power saving fluorescent lamp filament product.
