Abstract
The utility model discloses a main/auxiliary-tungsten filament single-core stacked triple-coil filament formed through coiling of a secondary filament coiling body in a spiral manner. The secondary filament coiling body comprises a primary filament coiling body and a secondary molybdenum filament, and further comprises a secondary auxiliary tungsten filament spirally coiled on the primary filament coiling body and the secondary molybdenum filament, the primary filament coiling body and the secondary molybdenum filament being disposed side by side; and the primary filament coiling body comprises a main tungsten filament and two primary molybdenum filaments and further comprises more than one primary auxiliary tungsten filament spirally coiled on the main tungsten filament and the two primary molybdenum filaments, the main tungsten filament and the two primary molybdenum filaments being disposed in a mutually adjoined manner and the primary auxiliary tungsten filaments being adjoined to each other. The main/auxiliary-tungsten filament single-core stacked triple-coil filament has the advantages of firm structure, high electronic powder storage capacity, rapid start upon energizing and long service lifetime.
Description
Technical field
The utility model relates to a kind of filament, particularly a kind of main and auxiliary type list core superposing type triple-coil filament.
Background technology
The life-span of power saving fluorescent lamp negative electrode depends primarily on the ability of the anti-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 subjected to Ions Bombardment to produce fracture of wire, the life-span of the fluorescent lamp knot that namely comes to an end.Therefore, how to strengthen the ability of the anti-Ions Bombardment of filament, improve the intensification usefulness of filament and the storage capacity of raising electronic powder and become 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 double-spiral structure filament.The filamentray structure of this structure is firm not; The electronic powder of storage is insufficient, causes cathode activation difficulty, filament energising startup slowly, so that early stage yellow deceiving appear in electricity-saving lamp, the useful life of fluorescent tube is undesirable.
The utility model content
The purpose of this utility model is, a kind of main and auxiliary type list core superposing type triple-coil 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: a kind of main and auxiliary type list core superposing type triple-coil filament, it by filament secondary winding body in the shape of a spiral coiling form, filament secondary winding body comprise side by side winding body of a filament and secondary molybdenum filament and one be spirally wrapped around side by side winding body of a filament and an auxiliary tungsten filament of secondary on the secondary molybdenum filament; Winding body of described filament comprise mutually near main tungsten filament and two molybdenum filaments arranging and be spirally wrapped around mutually near on main tungsten filament arranging and two molybdenum filaments more than one near once auxiliary tungsten filament.
In the aforesaid main and auxiliary type list core superposing type triple-coil filament, winding body of described filament comprises mutually near main tungsten filament and two molybdenum filaments arranging and is spirally wrapped around mutually near one on main tungsten filament arranging and two molybdenum filaments auxiliary tungsten filament once.
Compared with prior art, the utility model adopts main and auxiliary type list core superposing type triple-helix structure, so that filamentray structure is firm; Greatly increased the ability of filament store electrons powder, make the electronic powder reserves higher, cathode activation is more prone to, shortened filament preheating time, the filament energising starts faster, has improved the bombardment resistance energy of filament, and anti-bombardment ability is stronger, avoid the filament phenomenon of turning black in early days, prolonged the useful life of filament.

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.Main and auxiliary type list core superposing type triple-coil filament, as shown in Figures 1 to 3, it by filament secondary winding body in the shape of a spiral coiling form, filament secondary winding body comprise side by side winding body 4 of a filament and secondary molybdenum filament 6 and one be spirally wrapped around side by side winding body 4 of a filament and the auxiliary tungsten filament 5 of a secondary on the secondary molybdenum filament 6; Winding body 4 of described filament comprise mutually near main tungsten filament 3 and two molybdenum filaments 1 arranging and be spirally wrapped around mutually near on main tungsten filament 3 arranging and two molybdenum filaments 1 more than one near once auxiliary tungsten filament 2.Preferred version is selected an once auxiliary tungsten filament 2.
Add man-hour, as shown in Figures 1 to 3, with two molybdenum filaments 1 and a main tungsten filament 3 mutually near arrangement, again on the common spiral filament forming machine with one once auxiliary tungsten filament 2 be wound in the shape of a spiral above-mentioned mutually near two molybdenum filaments 1 arranging and main tungsten filament 3 on, obtain winding body 4 of filament; Then a winding body 4 and a secondary molybdenum filament 6 are arranged in parallel, on the common spiral filament forming machine an auxiliary tungsten filament 5 of secondary being wound in the shape of a spiral on above-mentioned winding body 4 that is arranged in parallel and the secondary molybdenum filament 6, obtain the secondary winding body again; After again filament secondary winding body being carried out thermal finalization processing, a secondary winding body is being twined on the core-pulling filament winding machine in the shape of a spiral side by side around to plug, extract plug out, carry out the second heat heat treatment after length cuts in accordance with regulations, can obtain main and auxiliary type list core superposing type triple-coil filament of the present utility model after again a molybdenum filament 1, secondary molybdenum filament 6 on the filament being dissolved.
