Abstract
The utility model discloses a double-tungsten-filament tertiary-spiral filament, comprising a spiral filament main body (1). The two ends of the spiral filament main body (1) are respectively provided with a filament foot (2). The double-tungsten-filament tertiary-spiral filament is characterized in that the filament feet (2) and the spiral filament main body (1) are formed by spiral filament secondary winding bodies (3) which are formed by filament primary winding bodies (4); each filament primary winding body is formed by winding of a main tungsten filament (5) and an auxiliary tungsten filament (6) which is spirally wound on the main tungsten filament (5). Compared with the existing common filament, in the double-tungsten-filament tertiary-spiral filament, the service life is longer, the winding speed of the filament is higher, filament breaking is not easy to occur, the storage amount of electronic powder is higher, the bombardment resistance is strong, and the temperature rise time is shorter.
Description
Technical field
The utility model relates to a kind of filament of electricity-saving lamp, particularly a kind of two tungsten filament triple-coil filaments that are used for the energy-conservation fluorescent lamp in tubule footpath.
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.
The burn-out life of power saving fluorescent lamp depends on the ability of filament stored electrons powder, and under the identical situation of the helical structure of filament, the storage capacity of electronics powder structure direct and the filament helical body has relation.At present, the length of helical body depends on the size of the caliber of fluorescent lamp, because the spiral of helical body can not short circuit in the caliber that limits, thus limited the storage area of electronics powder, thus the useful life of fluorescent tube influenced.
The utility model content
The purpose of this utility model is, a kind of longer service life, the faster and difficult generation fracture of wire of filament winding speed, strong, the shorter two tungsten filament triple-coil filaments of heating-up time of higher, the anti-bombardment ability of electronics powder reserves are provided.。
For solving the problems of the technologies described above, the technical solution of the utility model is as follows: two tungsten filament triple-coil filaments, it comprises spiral helicine filament main body, the two ends of filament main body are wire foot, described wire foot and filament main body are made up of helical heater secondary winding body, filament secondary winding body once twines body by 2 filaments to be formed, and filament once twines body and formed by the coiling of 1 tungsten filament helix shape.
In the above-mentioned monofilament triple-coil filament, the length of described filament helical body is 8.5～10.5mm, and the length of wire foot is 3～4mm.
Compared with prior art, filament secondary winding body of the present utility model once twines body by 2 filaments to be formed, filament once twines body and is formed by the coiling of 1 tungsten filament helix shape, therefore can increase the storage capacity of cathode electronics powder, and improve the firmness that the electronics powder adheres to; Electronics powder reserves are high more, be easy to the active electron powder more, shortened filament preheating time, the heating-up time is shorter, improve the bombardment resistance energy of filament greatly, anti-bombardment ability is stronger, avoids turning black in early days phenomenon, the contact area of electronics powder when also having increased the filament heating power greatly, fluorescent tube electronics powder in the exhaust decomposable process is heated evenly, cathode activation is easier, and energising starts faster, can significantly improve the useful life of fluorescent tube; Filament principal length and wire foot length are the results through applicant's repetition test, comparison, screening, summary, make result of use of the present utility model especially desirable.
