Abstract
The utility model discloses a composite winding energy-saving filament, which comprises a spiral rod structure formed by helically winding two parallel filament primary winding body (4) on a secondary main tungsten filaments (5); two parallel filament primary winding body (4) are tightly arranged side by side; the filament primary winding body (4) comprises one parallel primary main tungsten filament (1), one molybdenum (3), and one auxiliary tungsten filament helically winded on the parallel primary main tungsten filament (1) and the molybdenum (3). The utility model has advantages of firm structure, great storage capability of a filament electronic powder, good start-up performance, and long service life.
Description
Technical field
The utility model relates to a kind of filament, particularly a kind of composite winding energy-saving filament.
Background technology
The life-span of power saving fluorescent lamp negative electrode depends primarily on the ability of the resistance to Ions 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 when lighting fluorescent lamp maybe the electronic powder on being attached to filament exhausts, filament is because being subject to Ions Bombardment to produce fracture of wire, the life-span of the fluorescent lamp knot that comes to an end.Therefore, how to strengthen the ability of the resistance to Ions Bombardment of filament, the storage capacity of the intensification usefulness of raising filament and raising electronic powder has become and has extended filament and the key in power saving fluorescent lamp life-span.
At present, the multi-helical structure that the filament of the power saving fluorescent lamp on market adopts is around to the clubbed filament becoming, and structure is firm not, the electronic powder of storage is also insufficient, cause cathode activation difficulty, filament energising to start slow, electricity-saving lamp is occurred early stage yellow black, the useful life of fluorescent tube is undesirable.
Utility model content
The purpose of this utility model is, a kind of composite winding energy-saving filament is provided.The utlity model has sound construction; Filament electronic powder reserves are large, and startability is good, the advantage that the life-span is long.
The technical solution of the utility model: composite winding energy-saving filament, is characterized in: it comprises by winding body of two filaments side by side and is wound in the shape of a spiral the spiral club shaped structure forming on the main tungsten filament of secondary; Described two winding bodies of filament are side by side side by side near shape; Winding body of described filament comprises side by side one once main tungsten filament and a molybdenum filament, and is spirally wrapped around once main tungsten filament side by side and an auxiliary tungsten filament on molybdenum filament.
In above-mentioned composite winding energy-saving filament, the diameter of described once main tungsten filament is 0.036～0.0395 ㎜; The diameter of the main tungsten filament of described secondary is 0.052～0.06 ㎜; The diameter of described auxiliary tungsten filament is 0.016～0.022 ㎜; The diameter of described molybdenum filament is 0.05～0.07 ㎜.
Compared with prior art, the utility model adopts winding body of filament that main and auxiliary type is wound around time to be wrapped on the main tungsten filament of secondary side by side and forms bar-shaped helical structure, and this structure also coordinated the size of each main tungsten filament and auxiliary tungsten filament, makes filament more firm; Also greatly increased the ability of filament store electrons powder simultaneously, make electronic powder reserves higher, cathode activation is more prone to, shortened filament preheating time, filament energising starts faster, has improved the bombardment resistance energy of filament, and resistance to bombardment ability is stronger, avoid the filament phenomenon of turning black in early days, extended the useful life of filament.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of a winding body of the present utility model.
Being labeled as in accompanying drawing: 1-is main tungsten filament once, the auxiliary tungsten filament of 2-, 3-molybdenum filament, winding body of 4-filament, bis-main tungsten filaments of 5-.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.Composite winding energy-saving filament, as shown in Fig. 1 to 2, it comprises by winding body 4 of two filaments side by side and is wound in the shape of a spiral the spiral club shaped structure forming on the main tungsten filament 5 of secondary; Described two winding bodies 4 of filament are side by side side by side near shape; Winding body 4 of described filament comprises side by side one once main tungsten filament 1 and a molybdenum filament 3, and is spirally wrapped around once main tungsten filament 1 side by side and an auxiliary tungsten filament 2 on molybdenum filament 3.The diameter of described once main tungsten filament 1 is 0.036～0.0395 ㎜; The diameter of the main tungsten filament 5 of described secondary is 0.052～0.06 ㎜; The diameter of described auxiliary tungsten filament 2 is 0.016～0.022 ㎜; The diameter of described molybdenum filament 3 is 0.05～0.07 ㎜.
Add man-hour, as shown in Fig. 1 to 2, by one once main tungsten filament 1 and a molybdenum filament 3 be arranged in parallel, a more auxiliary tungsten filament 2 is wound in the shape of a spiral to above-mentioned of being arranged in parallel on common spiral filament forming machine once on main tungsten filament 1 and a molybdenum filament 3, obtain winding body 4 of filament; Then on common spiral filament forming machine, winding body 4 of two filaments is side by side wound on the main tungsten filament 5 of secondary in the shape of a spiral, length cuts into bar-shaped in accordance with regulations, then carry out second heat heat treatment, after finally the molybdenum filament on filament 3 being dissolved, can obtain the composite winding energy-saving filament that can use on electricity-saving lamp.
