Abstract
The utility model discloses a main/auxiliary-type single-core double-helix lamp filament. A lamp filament primary winding body is wound spirally to obtain the main/auxiliary-type single-core double-helix lamp filament. The lamp filament primary winding body comprises one main tungsten wire (1) and two molybdenum wires (3) which abut against each other, and more than two auxiliary tungsten wires (2) which are arranged side by side and are spirally wound on the one main tungsten wire (1) and the two molybdenum wires (3) which abut against each other. According to the main/auxiliary-type single-core double-helix lamp filament of the utility model, a main/auxiliary-type single-core double-helix structure is adopted; the capacity of storing electronic powder of the lamp filament is greatly increased; with lager electronic powder storage, a cathode can be activated with greater easiness, as a result, the preheating time of the lamp filament is shortened, and the lamp filament is energized and started faster; and further, the bombardment-resistant performance of the lamp filament is improved; with stronger bombardment-resistant ability, the blackening of the lamp filament in an early state can avoided, and the service life of the lamp filament can be prolonged.
Description
Technical field
The utility model relates to a kind of filament, particularly a kind of main and auxiliary type list core coiled 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 electronic powder of the filament storage of this structure 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 coiled coil filament is provided.It is large to the utlity model has the electronic powder reserves, 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 coiled coil filament, it by winding body of filament in the shape of a spiral coiling form; Winding body of described filament comprises mutually near a main tungsten filament and two molybdenum filaments of arranging, and is spirally wrapped around mutually side by side the auxiliary tungsten filament more than two near a main tungsten filament of arranging and two molybdenum filaments.
In the aforesaid main and auxiliary type list core coiled coil filament, winding body of described filament comprises a mutual main tungsten filament and two molybdenum filaments near arranging, and is spirally wrapped around mutually near a main tungsten filament of arranging and two auxiliary tungsten filaments side by side of two molybdenum filaments.。
Compared with prior art, the utility model adopts main and auxiliary type list core double-spiral structure, greatly increased the ability of filament store electrons powder, made 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.
Description of drawings
Fig. 1 is the structural representation of a winding body of the present utility model;
Fig. 2 is the cross section enlarged drawing of a winding body of the present utility model;
Fig. 3 is filament outline drawing of the present utility model.
Being labeled as in the accompanying drawing: 1-master's tungsten filament, the auxiliary tungsten filament of 2-, 3-molybdenum 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 coiled coil filament, as shown in Figures 1 to 3,1, main and auxiliary type list core coiled coil filament, it is characterized in that: it by winding body of filament in the shape of a spiral coiling form; Winding body of described filament comprises mutually near a main tungsten filament 1 and two molybdenum filaments 3 of arranging, and is spirally wrapped around mutually side by side the auxiliary tungsten filament 2 more than two near a main tungsten filament 1 of arranging and two molybdenum filaments 3.Preferred version is selected three auxiliary tungsten filaments 2.
Add man-hour, as shown in Figures 1 to 3, with a main tungsten filament 1 and two molybdenum filaments 3 mutually near arrangement, again common spiral filament forming machine will three auxiliary tungsten filaments 2 side by side be wound in the shape of a spiral above-mentioned mutually near main tungsten filament 1 arranging and two molybdenum filaments 3 on, obtain winding body of filament; Then will obtain winding body of filament and carry out thermal finalization processing, in the shape of a spiral side by side be wound into plug on the core-pulling filament winding machine winding body again, 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 coiled coil filament of the present utility model after again the molybdenum filament 3 on the filament being dissolved.
