Abstract
The utility model discloses a multi-auxiliary filament four-helical heater. The utility model is characterized in that the multi-auxiliary filament four-helical heater comprises a structure formed by spirally winding a triple filament winding body, wherein the triple filament winding body is formed by spirally winding a secondary filament winding body (6), the secondary filament winding body (6) is formed by spirally winding a primary filament winding body, and the primary filament winding body comprises a main tungsten filament (2) and two or three auxiliary tungsten filaments (3) spirally wound outside the main tungsten filament (2). The utility model has the advantages of higher reserve volume of the electronic powder, faster temperature rise during energization and prolonged service life of the filament.
Description
Technical field
The utility model relates to a kind of filament, the filament on particularly a kind of fluorescent lamp.
Background technology
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.
At present, the filament of the power saving fluorescent lamp on the market mainly adopts the triple-helix structure filament.The filament store electrons powder space of this structure is limited, and as above powder easily causes the cathode activation difficulty too much or decomposes not thoroughly, and it is early stage yellow black to make that electricity-saving lamp occurs, and the useful life of fluorescent tube is undesirable.
The utility model content
The purpose of this utility model is, a kind of many auxilliary silk four coiled filaments are provided.Its electronics powder reserves are higher, and energising heats up very fast, can prolong the useful life of filament.
The technical solution of the utility model: many auxilliary silk four coiled filaments, it is characterized in that: it comprises by filament three times twines the body structure that forms of shape coiling in the shape of a spiral, filament three times twine body 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 twines body by main tungsten filament be spirally wrapped around two of main tungsten filament outside or three auxilliary tungsten filament coilings and form.
In above-mentioned how auxilliary silk four coiled filaments, described filament once twines body and is formed by main tungsten filament and two auxilliary tungsten filament coilings that are spirally wrapped around main tungsten filament outside.
In aforesaid many auxilliary silk four coiled filaments, described filament once twines body and also can be formed by main tungsten filament and three auxilliary tungsten filament coilings that are spirally wrapped around main tungsten filament outside.
Compared with prior art, the utility model the utility model adopts the structure of quadruple spiral, increased the ability of store electrons powder greatly, made electronics 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.
