Description

Multiple main thread master-slave type three-helix energy-saving lamp filament and preparation method thereof
Technical field
The present invention relates to filament of a kind of electricity-saving lamp and preparation method thereof, particularly a kind of multiple main thread master-slave type three-helix energy-saving lamp filament that is entwined by the main tungsten filament more than three or three, molybdenum filament and the auxilliary tungsten filament more than one or and preparation method thereof.
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.
Present energy-saving lamp filament mainly adopts the master-slave type three-helix structure, promptly by a main tungsten filament and a molybdenum filament side by side as heart yearn, the outside is twined through three spirals with auxilliary tungsten filament and is formed the master-slave type three-helix structures.Though the filament bombardment resistance of this structure can be also better, the storage capacity of electronics powder is also more, and the contact area of electronics powder is big inadequately during the filament heating power, and cathode activation is slow, and lamp tube service life is not very desirable; If power is accomplished 300W, because operating current is big, main tungsten filament must be selected the tungsten filament of thick specification, and the tungsten filament of thick specification has increased the coiling difficulty, and fracture of wire also takes place easily, and product percent of pass is low, make fluorescent tube after reliability low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of longer service life, the faster and difficult generation fracture of wire of filament winding speed, higher, the anti-bombardment ability of electronics powder reserves is strong, the heating-up time is shorter multiple main thread master-slave type three-helix energy-saving lamp filament and preparation method thereof.
For solving the problems of the technologies described above, technical scheme of the present invention is as follows: multiple main thread master-slave type three-helix energy-saving lamp filament.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 by parallel near main tungsten filament more than three or three and molybdenum filament and the auxilliary tungsten filament coiling more than one or that is spirally wrapped around on main tungsten filament and the molybdenum filament form.
Above-mentioned multiple main thread master-slave type three-helix energy-saving lamp filament, specifically, filament once twine body be by parallel near three main tungsten filaments and molybdenum filaments and the auxilliary tungsten filament coiling more than one or that is spirally wrapped around on three main tungsten filaments and the molybdenum filament form.
Aforesaid multiple main thread master-slave type three-helix energy-saving lamp filament, filament once twine body be by parallel near three main tungsten filaments and molybdenum filament, and an auxilliary tungsten filament coiling that is spirally wrapped around on three main tungsten filaments and the molybdenum filament forms.
