Abstract
The invention provides a tungsten electrode, the whole is a cylinder, with a head, a middle part and an end portion, the end portion includes two sections: the caudad closes to the end portion and close middle part closes to the middle part. The caudad diameter is larger than that of the close middle portion, the middle part where closes to the head is provided with the first auxiliary tungsten coil, the middle part where closes to the end portion is provided with the second auxiliary tungsten coil. The tungsten electrode and high-pressure mercury discharge lamp that uses the tungsten electrode also puts forward a high pressure mercury mercury discharge lamp to adjust the tungsten eletrode, especially the improvement of the end portion to designe the end portion to be a dual-step shape, ensuring the expand with heat and contract with cold of tungsten electrode hardly bearing resistance force without exceeding the bearing strength borne by quartz to avoid bulb broken, meanwhile, the tungsten electrode is ensured not to be fractured easily, which improves the service life.
Description
Technical field
The present invention relates to photoelectric field, particularly relate to a kind of tungsten electrode, the invention still further relates to employing described tungsten electrode
High-voltage mercury discharging lamp.
Background technology
High-voltage mercury discharging lamp is, has two tungsten electrodes being arranged oppositely in an almost spherical quartz chamber body, two
Tungsten electrode relative position is fixed by fused quartz melt respectively, then passes through molybdenum sheet transition, realizes two tungsten electrodes and external power source wire
Connection.Molybdenum sheet is sealed by external heat source heat fusion with quartz glass, forms seal cavity.It is filled with rare in seal cavity
Luminous under gas and hydrargyrum discharge excitation effect between two tungsten electrodes.
Above-mentioned tungsten electrode head is thick, is suspended in seal cavity, afterbody is relatively tiny, is used for fixing in embedment quartz.
If tungsten electrode tail diameter selects larger (0.55mm or more), the flatulence of heat type of the part in tungsten electrode embedment quartz when point is turned off the light
Shrinkage amount exceedes quartzy bearing strength, bulb break easily；If tungsten electrode tail diameter select less (0.55mm or with
Under), intensity deficiency easily occurs and leads to lead rupture.
Content of the invention
The present invention propose a kind of tungsten electrode, solve the problems, such as above-mentioned in mention.
The technical scheme is that and be achieved in that: a kind of tungsten electrode, overall cylindrical, and have head, middle body,
Afterbody, described afterbody includes two sections, is proximate to caudad and the closely middle body portion near middle body of tail end, described closely middle body portion respectively
With diameter greater than described caudal diameter, described middle body is provided with the first auxiliary tungsten wire circle near the part of head, described near in
Body portion is provided with the second auxiliary tungsten wire circle near described caudal part.
By this design so that described afterbody becomes double step shape, realize the transition of deformation and dynamics.
Further, described caudal a diameter of 0.35-0.5mm.
Further, the diameter in a diameter of and described middle body portion in described closely middle body portion compares 0.33-0.66.
Further, described second auxiliary tungsten wire circle length is less than closely middle body minister's degree.
A kind of high-voltage mercury discharging lamp, employs described tungsten electrode.
Further, described high-voltage mercury discharging lamp, including quartz cavity, described quartz cavity two ends are symmetrically placed described tungsten electricity
Pole, described tungsten electrode caudad is fixing with described closely middle body portion embedment quartz, and by molybdenum sheet transition and external power source wire
Connect.
The described tungsten electrode of the present invention and the high-voltage mercury discharging lamp employing described tungsten electrode, by electric by described tungsten
Pole carries out structural adjustment, the improvement of especially described afterbody, makes described afterbody be designed to double step shape, wherein, thinner portion
Divide (i.e. caudad) and quartzy directly contact, play fixation；Thicker part divides (i.e. closely middle body portion) to be cladded with the second auxiliary tungsten wire circle,
Form non-direct contact with quartz it is ensured that described tungsten electrode expands with heat and contract with cold hardly is subject to resistance, not over quartzy bearing strength,
Prevent bulb break, meanwhile, can guarantee that described tungsten electrode does not allow easy fracture again, improve service life.
Brief description
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
Have technology description in required use accompanying drawing be briefly described it should be apparent that, drawings in the following description be only this
Some embodiments of invention, for those of ordinary skill in the art, without having to pay creative labor, also may be used
So that other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is a kind of planar structure schematic diagram of the present invention one embodiment of tungsten electrode；
Fig. 2 is the structural representation of an embodiment of high-voltage mercury discharging lamp of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
As shown in figure 1, a kind of tungsten electrode, overall cylindrical, and there is head 21, middle body 24, afterbody, afterbody includes two
Section, be proximate to respectively tail end caudad 22 and near middle body 24 closely middle body portion 23, closely middle body portion 23 with diameter greater than nearly tail
The diameter in portion 22, the diameter in middle body portion 24 is not less than the diameter in closely middle body portion 23, and in the present embodiment, middle body 24 is near the portion of head
It is arranged with the first auxiliary tungsten wire circle 41, closely middle body portion 23 is provided with the second auxiliary tungsten wire circle 42 near caudad 22 part.
By this design so that afterbody becomes double step shape, realize the transition of deformation and dynamics.
Further, a diameter of 0.35-0.5mm of caudad 22.
Further, the diameter in closely middle body portion 23 and the diameter in middle body portion 24 compare 0.33-0.66.
Further, the second auxiliary tungsten wire circle 42 length is less than closely middle body portion 23 length.
As shown in Fig. 2 a kind of high-voltage mercury discharging lamp, including quartz cavity 1, quartz cavity 1 two ends are symmetrically placed tungsten electrode
2, tungsten electrode 2 caudad 22 is imbedded in quartz with closely middle body portion 23, and is connected with external power source wire by molybdenum sheet 3 transition, its
