Abstract

The utility model discloses a master and secondary type tungsten filament four spiral filament, which comprises a four spiral body, wherein the first spiral body is a spiral body formed by the secondary tungsten filament winding around the master tungsten filament in spiral type, the second spiral body is a spiral body formed by the first spiral body winding in spiral shape, the third spiral body is a spiral body formed by the second spiral body winding in spiral shape, and the fourth spiral body is a spiral body formed by the third winding in spiral shape. The utility model is reasonable in structure, which largely increases amount of saved electron and contact area of the filament and the electron when the light is up, so that electron dust is evenly heated in the light discharging process. The cathode is easy to trigger, which improves quality of the fluorescent lamp and lengthens service life of the lighting tube.

Description

Major-minor tungsten filament formula four coiled filaments
Technical field:
The utility model relates to a kind of filament.
Background technology:
Existing Filament of fluorescent lamp is based on monofilament formula triple helical, mariages formula triple helical, major-minor filament type three helical and compound triple-coil filament, and its structure has explanation with name in national sector standard QB/T3734-2005.In the production of power saving fluorescent lamp, use major-minor filament type three helical filament more and more, but major-minor filament type three helical filament store electrons powder amount is few, and the tungsten filament in the major-minor filament type three helical filament is big not enough with the electronics powder contact area that is stored in the filament, cause in the system lamp bank gas process electronics powder inequality of being heated, the cathode activation difficulty, it is early stage yellow black to make that fluorescent lamp occurs, and shortens lamp tube service life.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and store electrons powder amount is big, the measured major-minor tungsten filament of fluorescent lamp matter formula four coiled filaments of making.
Technical solution of the present utility model is:
A kind of major-minor tungsten filament formula four coiled filaments, it is characterized in that: four helical layer bodies are arranged, the ground floor helicoid be by secondary tungsten filament around main tungsten filament helix shape around the helicoid that forms, second layer helicoid is that the ground floor helicoid is made helical form around the helicoid that forms, the 3rd helical layer body is that second layer helicoid is made helical form around the helicoid that forms, and the 4th helical layer body is that the 3rd helical layer body is made helical form around the helicoid that forms.
Secondary tungsten filament by one or two side by side near tungsten filament form.Ground floor, the second layer, the 3rd layer, the 4th helical layer body are that the cross section is that circular or oval-shaped spring-like connects helicoid.
The utility model is rational in infrastructure, owing to increased spiral one time than triple-coil filament, increased store electrons powder amount greatly, and when having increased the filament heating power and the contact area of electronics powder, the electronics powder is heated evenly in the feasible system lamp bank gas process, cathode activation is easy, has improved fluorescent lamp and has got quality, has prolonged lamp tube service life.And can be by major-minor silk formula four coiled filaments by main tungsten filament being got the various combination of diameter and four screw diameters, under the constant condition of other electrical quantitys, at an easy rate resistance is done greatly, be very easy to the coupling of filament and fluorescent tube.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is the configuration diagram of A portion among Fig. 1 (being the ground floor helicoid).
Fig. 3 is the spirochetal configuration diagram of the second layer.
Fig. 4 is the configuration diagram of the 3rd helical layer body.
Embodiment:
A kind of major-minor tungsten filament formula four coiled filaments, four helical layer bodies are arranged, the ground floor helicoid is by secondary tungsten filament 1 around main tungsten filament 2 helical forms around the helicoid that forms, second layer helicoid is that the ground floor helicoid is made helical form around the helicoid that forms, the 3rd helical layer body is that second layer helicoid is made helical form around the helicoid that forms, and the 4th helical layer body is that the 3rd helical layer body is made helical form around the helicoid that forms.
Secondary tungsten filament by a tungsten filament (or two side by side near tungsten filament) form.Ground floor, the second layer, the 3rd layer, the 4th helical layer body are that the cross section is that the spring-like of oval (or circular) connects helicoid.
