Abstract
The utility model relates to a kind of xenon lamp black box, comprise bead, tungsten bar and glass tube, the quantity of described bead is only one, described tungsten bar to be perforated through in described bead and to fire to merge with described bead and is connected, described glass tube only vertically seal welding extremely the wherein side that penetrated by described tungsten bar of described bead is on the surface.In xenon lamp black box of the present utility model, only use a bead, preferably adopt mould to make bead be shaped to flat cylindrical shape; And not using transition material directly to seal, glass tube and bead only fuse vertically, and reduce the impact of the residual stress that radial upper fusion easily produces, achieve process for sealing melt region little, fluorescent tube airtight quality is more reliable; Save the expense of a bead and transition material, technique is also more simple, thus cost is reduced simultaneously.
Description
Technical field
The utility model relates to flash lamp illumination technical field, more particularly, relates to a kind of xenon lamp black box.
Background technology
The compositions such as the usual material comprises glass pipe of xenon lamp black box, bead, tungsten bar, under vacuum conditions, are completed the sealing-in of glass tube and bead, pour quantitative xenon and reach the object causing flash of light in glass tube by machine.Conventional art fires together by two beads with tungsten bar, two beads need be fired into step-like, and then adopt transition material bead and glass all to be sealed in axis and radial direction, therefore conventional art xenon lamp black box not only needs use two beads, and need to use transition material glass and bead to be fused together, if do not use transition material, fluorescent tube that sealing-in completes is axial, and residual stress is excessive easily splits, cause technique more complicated and percent defective is high, and manufacturing cost is higher.
Utility model content
The purpose of this utility model is to provide one to make the easy xenon lamp black box of xenon lamp sealing technology, solves the problem that in prior art, xenon lamp sealing technology is complicated, percent defective is high and cost is high.
The technical scheme that the utility model technical solution problem adopts is: a kind of xenon lamp black box, comprise bead, tungsten bar and glass tube, the quantity of described bead is only one, described tungsten bar to be perforated through in described bead and to fire to merge with described bead and is connected, described glass tube only vertically seal welding extremely the wherein side that penetrated by described tungsten bar of described bead is on the surface.
In xenon lamp black box of the present utility model, described bead is cylindrical shape.
In xenon lamp black box of the present utility model, the diameter of described bead cross section is greater than the height of described bead.
In xenon lamp black box of the present utility model, the ratio of the diameter of described bead cross section and the height of described bead is 3 ~ 10.
In xenon lamp black box of the present utility model, described tungsten bar crosses described bead along the axial penetration of described bead.
In xenon lamp black box of the present utility model, the axis of described glass tube is identical with the direction of the axis of described bead with described tungsten bar respectively.
In xenon lamp black box of the present utility model, described tungsten bar is perforated through described bead at the cental axial position of described bead.
Implement xenon lamp black box of the present utility model, there is following beneficial effect: in xenon lamp black box of the present utility model, only use a bead, preferably adopt mould to make bead be shaped to flat cylindrical shape; And not using transition material directly to seal, glass tube and bead only fuse vertically, and reduce the impact of the residual stress that radial upper fusion easily produces, achieve process for sealing melt region little, fluorescent tube airtight quality is more reliable; Save the expense of a bead and transition material, technique is also more simple, thus cost is reduced simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the xenon lamp black box of prior art;
Fig. 2 is the structural representation of xenon lamp black box of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, xenon lamp seal component architecture of the present utility model is described further:
As shown in Figure 1, xenon lamp black box of the prior art comprises two bead 1a, two bead 1a are not of uniform size, it is stepped after two bead 1a are superposed, tungsten bar 2a is perforated through two bead 1a respectively and fusion is fired together, and glass tube 3a respectively radially welds and then realize to seal with axially being fused with bead 1a by transition material 4a.As can be seen here, the xenon lamp black box of prior art not only needs use two bead 1a, and need to use transition material 4a to be fused together by glass tube 3a and bead 1a, if do not use transition material 4a, glass tube 3a that sealing-in completes is axial, and residual stress is excessive easily splits, cause technique more complicated and percent defective is high, and manufacturing cost is higher.
As shown in Figure 2, the utility model provides one to make the easy xenon lamp black box of xenon lamp sealing technology, and comprise bead 1, tungsten bar 2 and glass tube 3, wherein the quantity of bead 1 is only one, bead 1 is cylindrical shape preferably, also can be other shape in other embodiments.In the present embodiment, bead 1 is that the diameter of the cross section of bead 1 is greater than the height of bead 1, and preferably, the ratio of the diameter of bead 1 cross section and the height of bead 1 is 3 ~ 10 in flat cylindrical shape.In the present embodiment, the ratio of the diameter of bead 1 cross section and the height of bead 1 is 8, and in other embodiments, the ratio of the diameter of bead 1 cross section and the height of bead 1 can be 3,6 or 10 etc.
Tungsten bar 2 is perforated through bead 1 and fires to merge with bead 1 and is connected, and then the two is fixedly connected with, and wherein tungsten bar 2 preferably crosses bead 1 along the axial penetration of bead 1, and more preferably, is perforated through bead 1 at the cental axial position of bead 1.
Only the wherein side that penetrated by tungsten bar 2 to bead 1 of seal welding is on the surface vertically for glass tube 3, and glass tube 3 is axially identical with the direction of the axis of bead 1 with tungsten bar 2 respectively, wherein one end of tungsten bar 2 is sealed in glass tube 3, therefore glass tube 3 is directly soldered on bead 1, do not need transition material, also be not radially connected with bead, the impact of the residual stress that radial upper fusion easily produces is reduced by such design, achieve process for sealing melt region little, glass tube airtight quality is more reliable.
In xenon lamp black box of the present utility model, only use a bead, preferably adopt mould to make bead be shaped to flat cylindrical shape; And not using transition material directly to seal, glass tube and bead only fuse vertically, and reduce the impact of the residual stress that radial upper fusion easily produces, achieve process for sealing melt region little, fluorescent tube airtight quality is more reliable; Save the expense of a bead and transition material, technique is also more simple, thus cost is reduced simultaneously.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, all these improve or conversion all should belong within the protection range of the utility model claims.
