Abstract

The utility model discloses a four-filament, tri-spiral energy-saving lamp filament. The filament is made of a spirally wound secondary wound filament body (3); wherein, the secondary wound filament body (3) is made of a spirally wound primary wound filament body (2); and the primary wound filament body (2) is made of four or more wound tungsten filaments (1) which abut against one another. Since the tungsten filaments (1) are synchronously wound side by side in a tri-spiral manner to form the filament, the electron powder reserve is higher, cathode activation becomes easier, the warm-up time of the filament is shortened, the electrified filament can be started more quickly, and the service life of the filament is greatly prolonged. Moreover, the production cost is reduced, and the production efficiency and the acceptability rate of the product are increased.

Description

Filament of four-filament three-helical energy saving lamp

Technical field

The utility model relates to a kind of filamentray structure of electricity-saving lamp, particularly a kind of filament of four-filament three-helical energy saving lamp that is formed by the tungsten filament coiling more than four or four.

Background technology

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.

At present, the filament of the power saving fluorescent lamp on the market mainly adopts monofilament triple-helix structure or mariages triple-helix structure, promptly twines through three spirals with a tungsten filament or two tungsten filaments and makes.The electronics powder of the filament storage of this structure is insufficient, and it is slow to cause cathode activation difficulty, filament energising to start, and it is early stage yellow black to make that electricity-saving lamp occurs, and the useful life of fluorescent tube is undesirable.And production efficiency is low when twining, fracture of wire easily, and exhaust efficiency is low, influences the reliability of fluorescent tube.

The utility model content

Technical problem to be solved in the utility model is, a kind of filament of four-filament three-helical energy saving lamp is provided.Not only electronics powder reserves are higher, the energising intensification is very fast for this filament, can prolong the useful life of filament, and production efficiency are higher, is not easy fracture of wire.

For solving the problems of the technologies described above, the technical solution of the utility model is such: filament of four-filament three-helical 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 be by near the tungsten filament coiling more than four or four form.

Above-mentioned filament of four-filament three-helical energy saving lamp, specifically, filament once twine body be by near four tungsten filament coilings form.

Aforesaid filament of four-filament three-helical energy saving lamp, filament once twine body also can be by near five tungsten filament coilings form.

Aforesaid filament of four-filament three-helical energy saving lamp, filament once twine body can also be by near the coiling of six roots of sensation tungsten filament form.

The beneficial effects of the utility model: the utility model adopts the tungsten filament more than four or four to carry out three sections spiral windings side by side synchronously, increased store electrons powder amount greatly, make electronics powder reserves higher, cathode activation is more prone to, and has shortened filament preheating time, and the filament energising starts faster, improved the bombardment resistance energy of filament, anti-bombardment ability is stronger, avoids the filament phenomenon of turning black in early days, has prolonged the useful life of filament.And under the identical situation of gross power, owing to adopt the tungsten filament of greater number to twine side by side, carefully more a lot of than the diameter that adopts a tungsten filament or two tungsten filaments to twine the tungsten filament that is adopted, production cost reduces greatly that (gross power of four thin tungsten filaments is equivalent to a thick tungsten filamen, but the cost of four thin tungsten filaments is more much lower than the cost of a thick tungsten filamen), not only speed of wrap is faster, wrapping wire efficient is higher (to be needed on every centimeter length when adopting a tungsten filament to twine originally around 240～250 circles, only need be on every centimeter length when adopting four tungsten filaments to twine now around 60 circles, wrapping wire efficient can improve 75%), and when twining, be difficult for taking place fracture of wire, the product percent of pass height, make fluorescent tube after reliability higher.
