Abstract

The utility model discloses a multi-filament lamp which belongs to a lighting lamp. The utility model is characterized in that a plurality of filaments are additionally arranged in the existing lamp (such as a daylight lamp tube, an H-shaped energy-saving lamp tube, etc.); the filaments are divided into a starting filament and working filaments; the working filaments which has a certain number works when the lamp is emitting light; the working filaments can be used successively with the aid of a switching device. The utility model has the advantage that the service life of the lamp is increased by times.

Description

Multi-filament lamp set

The utility model relates to a class lighting, and it is applied to adopt in the lighting of the luminous or emitting electrons of filament.

At present, the fluorescent tube of light fixtures such as traditional fluorescent lamp, H type electricity-saving lamp, constitute by the mercury vapour in plug, heater lead, filament, glass shell and the fluorescent tube, fluorescent lamp build-up of luminance (lighting) mode generally can be divided into two kinds: the hot build-up of luminance of Inductive ballast and the cold build-up of luminance of electric ballast (also having extremely, other electric ballast is hot build-up of luminance), so-called hot build-up of luminance, be exactly to make filament heating back build-up of luminance fluorescent tube by electric current earlier in the filament, cold build-up of luminance then is that the lamp tube ends filament does not generate heat and just directly adds and high voltage is lighted by lamp lighting-up; Fluorescent tube after lighting, just transmit and receive electronics and keep lamp luminescence by filament, the filament of every end only is one in the fluorescent tube of this class light fixture at present, lamp lighting-up and luminous all are these root filaments, but the life-span of fluorescent tube just depend on this root filament, and can be divided into two aspects: i.e. moment of build-up of luminance and light times two aspect to burn-out life influence ground external factor, test factually, because the immediate current of build-up of luminance is big, temperature is high, be the main cause that causes filament to damage, account for 6 one-tenth; If the filament one of arbitrary end is disconnected in the lamp tube ends, just cause scrapping of whole fluorescent tube.The most tangible example is exactly the fluorescent tube of fluorescent lamp, turns black at two ends before this with fluorescent tube after a period of time, and then very fast fluorescent tube has just been scrapped.The life-span of a fluorescent tube is very short.

The purpose of this utility model is exactly by adopting a plurality of filaments, not only making fluorescent tube normally luminous, and the life-span of fluorescent tube is significantly improved.

The utility model is achieved like this: the filament of the every end of fluorescent tube is made many, build-up of luminance is showed the score with point to be born by different filaments, and make every end build-up of luminance filament be divided into two, allow a filament job earlier, after work a period of time, there is the filament of an end to break, at this moment adopt certain conversion equipment, re-use an other filament, make fluorescent tube luminous again, filament in fluorescent tube has an end has all broken, and this root fluorescent tube is just scrapped.The life-span of fluorescent tube just can significantly improve like this.

Be that example specifies how to realize the utility model below with the fluorescent-lamp tube:

Figure one is the local schematic diagram of the utility model fluorescent tube.

Figure two is a kind of structures of the filament of the utility model fluorescent tube.

Figure three is structures of traditional fluorescent lamp filament.

In figure one, figure two, figure three:

1,2,3 is filament among the figure.

4,5,6 is heater lead.

7 is the screw of inner conduction.

8 is reverse stem.

9 and 10 is lamp tube ends plug (electrode).

11 is insulation board.

12 is the metal cap of lamp tube ends.

13 for covering on a little garden tube cover outside the filament.

14 tube glass.

Filament

1 and 2 is as build-up of luminance and the dual-purpose filament of work among the figure two, and filament 3 is only as build-up of luminance rear running light silk; When adopting hot build-up of luminance, filament 1 heating power is the build-up of luminance fluorescent tube then, but because filament 3 is leading, behind lamp lighting-up and replace filament 1 emitting electrons automatically and keep lamp luminescence, filament 1 not work this moment, like this, because the participation of 3 filaments, add filament 1 and work successively, thereby make lamp tube service life improve more than the twice at least with filament 2; When fluorescent tube adopts cold build-up of luminance, though

filament

1 and 3 all is added with voltage, but filament 3 is preceding and directly excite fluorescent tube and keep lamp luminescence, because filament 3 is ring-like, it can not be worked with the top for disconnected at least twice, but this moment,

filament

1 and 2 can be worked again successively, calculated like this, and lamp tube service life is traditional more than four times of lamp tube service life.

Below in conjunction with Figure of description one, specify a kind of structure (can be designed to multiple structure) of multi-filament fluorescent tube.

Heater lead 6 links to each other with plug 10, heater lead 5 links to each other with plug 9, heater lead 4 links to each other with stem 8,

filament

1 and 2 conversion are such: fluorescent tube uses the initial stage earlier with filament 1, filament 2 then is not connected with plug 9 owing to reverse stem 8 and does not work, (this moment screw 7 not precession go) has no progeny when filament 1 usefulness, as long as screw 7 precessions are gone with screwdriver, plug 9 is linked to each other by screw 7 with stem 8, like this, filament 2 is communicated with

plug

9,10 again and works, and fluorescent-lamp tube is just luminous again.Little cover 13 prevents lamp tube ends blackout usefulness, its principle be the electrodeposition substance that evaporates of filament on little cover 13, thereby prevented to be deposited on the glass tube of lamp tube ends and made the fluorescent tube blackout.

Claims

1, a kind of lighting mainly is made of glass shell, filament, heater lead and plug, it is characterized in that: its filament is to be made of a plurality of filaments that cover in the little cover.

2, according to claim 1 described lighting, it is characterized in that: filament is divided into build-up of luminance filament and work filament two parts, and respectively has some (1～3) individual.

3, according to claim 1 described lighting, it is characterized in that at filament outer mask one little cover, be used for depositing the material of filament volatilization, prevent the glass shell blackout of light fixture.
