CN2606454Y - Reusable incandescent bulb - Google Patents

Abstract

The utility model disclose a reusable incandescent bulb which comprises a bulb head, a bulb shell, an oviduct, a light core and electrical source touch point. The utility model is characterized in that: the oviduct is provided inside with a length of alternative conducting filament and a length of fixed conducting filament extends into the inside of the bulb, passing through the oviduct; additionally, a group of lengthes of conducting filament having one end connected with the length of alternative conducting filament respectively and the other end extend to the inside of the bulb shell are also arranged; a group of lengthes of filament having one end connected with the length of fixed conducting filament and the other end the extending out ends of the group of lengthes of conducting filament respectively; so when one length of filament is burnt out, the filament can be connected with another filament to illuminates again; as a major incandescent bulb consuming country, our country adopts the utility model to prolong the serving life of the common incandescent bulb which is determined by the serving life of the filament, thereby reducing the environment pollution caused by the abandoned bulbs and bringing enormous economic and social benefits.

Description

A kind of reusable incandescent lamp bulb

Technical field

The utility model belongs to lighting field, relates in particular to a kind of reusable incandescent lamp bulb.

Background technology

After the ordinary incandescent lamp bubble used certain hour, at first filament can break because of aging, caused whole bulb can not continue illumination and used, and can only throw away as discarded object.The consumption of bulb is very big, about 3,000,000,000 of the quantity of China's year consumption bulb.Because bulb is to be made of a variety of materials, to scrap the back and be difficult to recycle, this can cause the significant wastage of social resources, has also polluted environment.If behind filament break, can reuse, thus the life-span of prolongation bulb, and just can save great amount of manpower and material resources, the minimizing environmental pollution alleviates consumer's burden, produces huge economic benefit and social benefit.

There was the people once to take to punch in the past at the top of Lamp bulb case, after filament breaking is changed again, vacuum-pumping and sealing again, make " regeneration bulb ", but because secondary vacuum pumping can't reach original vacuum degree standard, the bulb service life after the regeneration is extremely short, is not applied; Afterwards, the someone imagines establish two filaments in bulb again, changes the contact on the lamp holder into three by two, and also changes the contact on the bulb socket into three by two, when first filament with having no progeny, can reach reusable purpose as long as the contact of lamp holder replaced.But doing one like this is that versatility is poor, change bulb socket in a large number, the 2nd, can't on screw-socket bulb, implement, and it is bigger to apply difficulty.

Summary of the invention

The purpose of this utility model is to provide a kind of can make reusable reusable incandescent lamp bulb behind the existing incandescent lamp bulb disintegration of filament, thereby effectively addresses the above problem.

The utility model is to realize like this, the lamp holder bottom is connected with oviduct, oviduct and wick to be one and to place in the cell-shell, cell-shell is connected with lamp holder, one fixedly seal wire connect power contact and stretch in the cell-shell by oviduct, a conversion seal wire connects another power contact and places in the oviduct, one group of seal wire one end places in the oviduct and can join with the conversion seal wire respectively, its other end stretches in the cell-shell, one group of filament one end all joins with the end points that fixing seal wire stretches out, and its other end joins with the end that its seal wire stretches out respectively.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

Description of reference numerals is as follows:

Filament 1, filament 2, cell-shell 3, fixedly seal wire 4, wick 5, oviduct 6, lamp holder 7, conversion seal wire 8, seal wire 9, seal wire 10, power contact 11, power contact 12.

Embodiment

Below in conjunction with accompanying drawing enforcement of the present utility model is described further, be provided with oviduct (6) in lamp holder (7) bottom, oviduct (6) is one with wick (5) and places in the cell-shell (3), cell-shell (3) is connected with lamp holder (7), one fixedly seal wire (4) connect power contact (11) and stretch in the cell-shell (3) by oviduct (6), a conversion seal wire (8) connects another power contact (12) and places in the oviduct (6), seal wire (9,10) the one end places in the oviduct (6) and can join with conversion seal wire (8) respectively, its other end stretches in the cell-shell (6), filament (1,2) the one end all joins with the end points that fixing seal wire (4) stretches out, its other end respectively with seal wire (9,10) end points that stretches out joins.

The conversion seal wire is joined with any seal wire wherein, can throw light on after the energising.After used filament had broken, hand-held lamp holder reinforcing on certain direction made it vibrations, the conversion seal wire is broken away from formerly join with another root seal wire with seal wire, and bulb just can throw light on again, thereby realizes reusable function.

Claims (1)

1. A kind of reusable incandescent lamp bulb, it is the oviduct (6) that connects by lamp holder (7) and bottom, the wick (5) that is connected as a single entity with oviduct (6), power contact (11,12), the cell-shell (3) of sealing is formed, it is characterized in that one fixedly seal wire (4) connect power contact (11) and stretch in the cell-shell (3) by oviduct (6), a conversion seal wire (8) connects another power contact (12), place in the oviduct (6), one group of seal wire (9,10) the one end places in the oviduct (6) and can join with conversion seal wire (8) respectively, its other end stretches in the cell-shell (3), one group of filament (1,2) the one end all joins with the end points that fixing seal wire (4) stretches out, its other end respectively with its seal wire (9,10) end that stretches out joins.
