Abstract
The electric light source with several filaments consists of glass casing, filaments, guide wires, exhaust pipe, horn and lamp holder. Its advantages are simple structure, ingenious design, low cost, convenient application, and long service life of electric light source.
Description
The present invention relates to a kind of electric light source, particularly a kind of electric light source that a plurality of filaments are arranged.
At present, electric light source is varied, if any the thermal radiation electric light source, and the gas discharge electric light source, but these electric light source major parts have only a filament or two filaments, as bulb, fluorescent tube, as long as disintegration of filament, just be done for, thereby useful life is shorter, this is existing deficiency with electric light source at once.
The purpose of this invention is to provide a kind of electric light source, this electric light source such as bulb, fluorescent tube have two filaments at least in each electric light source, fluorescent tube has four filaments at least, has burnt out one, just can reinstate another, in order to improve the life-span, overcome the deficiency of existing electric light source.
Purpose of the present invention can reach by following embodiment:
The present invention is by glass shell, filament, seal wire, blast pipe, oviduct and lamp holder are formed, glass shell, blast pipe, oviduct is with now using electric light source, its difference is a filament, seal wire and lamp holder, filament has at least more than two, contain two, only rare three or four of seal wire, the lamp holder shape is substantially with existing lamp holder, just increased a multidirectional selector switch on top near the glass shell place, multidirectional selector switch has two contacts, after a filament is damaged, just can be by the contact of the multidirectional selector switch of change, make two seal wires connections elsewhere, another filament is worked on, thereby can improve the useful life of electric light source.
The present invention also can be used for the gas discharge electric light source, that is to say the electric light source of a plurality of electrodes, as fluorescent lamp, but filament has at least more than three, and seal wire is answered corresponding increase, and two is equipped with multidirectional selector switch, promptly a disintegration of filament changes multidirectional selector switch and uses another again.
Advantage of the present invention is simple in structure, is skillfully constructed, and is cheap, easy to use, is a kind of desirable, practical electric light source the useful life that can improve electric light source.
The present invention is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the overall structure schematic diagram of bulb for the thermal radiation electric light source.
Fig. 2 is a fluorescent tube overall structure partial schematic sectional view for the gas discharge electric light source.
Fig. 3 is the fluorescent tube electrical schematic diagram.
As Figure 1-3, this electric light source is that bulb is made up of glass shell 1, filament, seal wire, blast pipe 7, oviduct 9 and lamp holder 13, glass shell 1, blast pipe 7, oviduct 9 are bulb with electric light source now together, its difference is embodied on filament, seal wire and the lamp holder, the present embodiment filament has three, be filament first 20, filament second 3, filament the third 21, seal wire has inner guide wire 5, Dumet wire 6, outer leading lights silk 8 to be formed by connecting, anodal seal wire has one, and the negative pole seal wire has three i.e. cloudy seal wire 10, two cloudy seal wire 19, three cloudy seal wires 18.Lamp holder 13 shapes substantially with existing lamp holder, have just increased a multidirectional selector switch 14 on top near glass shell 1 place, and multidirectional selector switch 14 has two contacts, i.e. moving contact 12 and fixed contact, and fixed contact connects cloudy line 17.Multidirectional selector switch 14 also two contacts be armature contact, promptly connect during positive and negative electrodes in same, disconnect simultaneously, in this case, electric light source has a plurality of positive poles and negative pole.After a filament is damaged, two cloudy seal wires 19 are connected, make 3 work of filament second, thereby bulb can continue luminous.After filament second 3 is bad, can also change filament the third 21, analogize in proper order.In order to guarantee insulation, lamp holder 13 places also establish porcelain tube 11, and porcelain tube 11 and lamp holder 13 have been bonded in.
The present invention also can be used for gas discharge electric light source such as fluorescent tube, but filament also has two above filaments at least except that filament first 20 is arranged, need 14, two porcelain tubes 11 of two multidirectional selector switches on it, and lamp base 22, fluorescent material 23, glass tube 24 are with now using fluorescent tube.
The setting of thermal radiation electric light source molybdenum wire hook of the present invention (4) can according to how many settings of filament, and promptly filament is many, and molybdenum wire hook (4) is many.
Claims (7)
1, a kind of electric light source that a plurality of filaments are arranged, form by glass shell (1), filament, seal wire, blast pipe (7), oviduct (9) and lamp holder (13), glass shell (1), blast pipe (7), oviduct (9) are with now using electric light source, it is that filament causes rare two that its feature is levied, seal wire causes rare three or four, and lamp holder (13) is located at multidirectional selector switch (14) on top near the glass shell place.
2, electric light source according to claim 1 is characterized in that its also gas discharge electric light source, that is to say the electric light source of a plurality of electrodes, and as fluorescent lamp, but that filament causes is rare more than three, and two is equipped with multidirectional selector switch (14).
3, electric light source according to claim 1 is characterized in that multidirectional selector switch (14) has two contacts, i.e. moving contact (12) and fixed contact, and fixed contact connects cloudy line (17).
