Abstract

The utility model discloses a bulb for illumination, which is formed by that more than two sets of filament structures and an elastic metallic sheet which can be toggled respectively contact the joints of each set of filaments, and the metallic sheet is on a lamp cap, the filaments with different power can be selected for providing lighting effects with different brightness. When one set of filaments is burnt, normal illumination can be recovered by toggling the elastic metallic sheet to the contact of the lamp cap of another set of filaments, and thus one bulb of the utility model can be used for replacing a plurality of bulbs.

Description

Multi-power long service life bulb

The utility model belongs to a kind of illuminating bulb.

Existing commercially available bulb generally is made of one group of filament, glass shell, stem stem, lamp holder.The fundamental cause that influences bulb life is that filament is burnt easily, owing to adopt one group of filament, once burnt, whole bulb can not be used.The glass shell of bulb, stem stem, lamp holder all waste, and have so not only wasted raw material but also contaminated environment.

In order to save material and to prolong the useful life of whole bulb, the utility model has designed a kind of many power long-life bulb.

Key problem in technology of the present utility model is to adopt two groups of above filaments (8), each organizes filament a common junction (10), with conductor common junction is connected with contact (1) on the lamp holder, the other end of filament uses conductor to be connected with each contact (7) on the lamp holder respectively, there are the elastic sheet metal that to stir (6) and each contact to keep well contacting, by stirring elastic sheet metal (6) on the lamp holder to each contact, can select the filament of respectively organizing different capacity for use.

Filament is arranged to arc, and every group of filament is arranged on the warp or parallel of arc body equably, and the filament that is arranged on the parallel adopts the filament arrangement form that has bulb now.Be floor plan or layered arrangement, filament on warp is arranged with broken line form, in case obsolete filament is in the light, each is organized an end and the common junction (10) of filament and connects, and on being drawn out to contact (1) on the lamp holder by a lead along wick column, each organizes each wiring of another termination of filament, and guides on each contact of lamp holder.The quantity of lamp holder contact conforms to the group number of filament, promptly has one group of filament that a contact is just arranged, have how much to organize filament how many contacts are just arranged, and the corresponding connection of an end of each contact on the lamp holder and each group filament.Each contact is evenly distributed on the concentric garden of lamp holder, and not with housing contacts.Contact with each contact on the lamp holder respectively by the elastic sheet metal of stirring on the lamp holder, reach and light the purpose of respectively organizing filament.After one group of filament in the bulb is burnt, take off bulb, the elastic sheet metal of stirring on the lamp holder is organized on the lamp holder contact of filament to another, energized, the filament of this group is promptly lighted.So the contact stirred on the lamp holder of elastic sheet metal and each filament of order contact, can light the filament of each group respectively, reaches the effect that a bulb pushes up several bulbs uses.

Be example in the bulb bulb of six groups of filaments to be arranged below, the utility model is described in further detail.

Fig. 1 is the front schematic view of bulb.

Fig. 2 is the schematic diagram of filament.

Fig. 3 is from A mansion view.

Fig. 4 is the cutaway view of B-B in the bulb.

Among Fig. 1, (1) is the contact of filament common junction (10) on lamp holder, (2) be the fixing screw of elastic sheet metal, (3) be another contact of lamp holder, (2) and use the sheet metal conducting between (3), (4) are lamp shells, and (5) are the glass shells of bulb, (6) be elastic sheet metal, (7) be respectively organize the contact of filament on lamp holder wherein.Bullet on the lamp holder is each contact, is decorated with 6 points among Fig. 3, has a bit to be covered by elastic sheet metal, and (8) are the schematic diagrames of filament, and (9) are the bearing supports of filament, and (10) are the common junction of respectively organizing filament one end.

The lead-in wire of the contact on the lamp holder (1) causes on the common junction (10) of respectively organizing filament from the bulb center, contact (3) is by sheet metal and elastic sheet metal (6) conducting, elastic sheet metal (6) is fixing with screw (2), select contact respectively to organize the lamp holder contact (7) of filament by stirring elastic sheet metal (6), connect with the mains, filament light-emitting, use the same with tungsten filament lamp for general service.

After one group of filament is burnt, stir elastic sheet metal (6) to the lamp holder contact of another group filament, can recover illumination.

Respectively organize the filament that filament can be made different capacity in bulb, for example, make the filament of different capacities such as 5W, 10W, 20W, 60W, also can make the filament of equal-wattage, like this, by stir elastic sheet metal (6) to each the group different capacity filament on the contact of lamp holder, can select the light of different brightness.Reach the purpose of light modulation, and played a lamp and pushed up the effect that several lamps are used, like this, both saved raw material, prolonged the useful life of whole bulb again.

Claims (1)

1, a kind of illuminating bulb, by lamp holder, filament, glass shell, stem stem constitutes, it is characterized in that plural contact [7] is arranged on the described lamp holder, the elastic sheet metal that can stir [6] keeps excellent contact with each contact, two groups of above filaments [8] are arranged, and each organizes filament a common junction [10], is connected with contact [1] on the lamp holder with conductor.The other end of filament is connected with each contact on the lamp holder with conductor respectively, by stirring elastic sheet metal [6] on the lamp holder to each filament contact, select for use and respectively organize filament, the filament of described bulb is arranged to arc body, every group of filament is arranged on the warp or parallel of arc body equably, filament on parallel is with plane or layered arrangement, and the filament on warp is arranged with broken-line type.
