Description
Technical field
The present invention relates to a kind of production method of Metal halogen lamp, particularly the production method of exhaust-pipe-free pulse enable type Metal halogen lamp.
Background technology
Metal halogen lamp produces the luminous discharge lamp of arc discharge with alternating current as power work, in the halide mixed vapour of mercury and rare metal; According to the difference of its production technology, can be divided into blast pipe pulse enable type Metal halogen lamp is arranged (being called for short UPS) and exhaust-pipe-free pulse enable type Metal halogen lamp (abbreviation TPS).The structure of Metal halogen lamp generally includes the cell-shell of an elliposoidal, and starting electrode is housed in the cell-shell, and is marked with said mixed vapour, and the sealing two ends of ellipsoid, sealing part forms a bowl end.Cell-shell can be moulded quartz ampoule through hot blow and obtain, and its former body is generally a long pipeline, then to the centre heat, inflation, form the stage casing and become elliposoidal, elliposoidal two to narrow the cell-shell raw material (with reference to Fig. 1) that end is communicated with the residue long tube.The cell-shell raw material comprises cell-shell part and the surplus tube portion that is communicated with cell-shell two.Cell-shell is carried out a press seal (referring to seal cell-shell on one side) afterwards; Deshydroxy be will carry out, mercury, injection ball annotated; The operation of discharge electrode, positioning of electrode, blanketing gas, ion envelope, last two press seals (referring to seal the cell-shell of another side) excise the surplus pipe of that side behind two press seals.Yet the pressure of the gas of filling is much smaller than an atmospheric pressure; And press packing equipment is in air, therefore cell-shell in the press seal process---at the bottom of the cell-shell bowl, problems such as interior notch distortion appear very easily particularly; In order to prevent to be out of shape at the bottom of the cell-shell bowl; Traditional manufacture craft is just inserted the blast pipe in the cell-shell in one of design in the press seal process, and ventilate in the cell-shell through blast pipe then makes the cell-shell internal and external pressure balance always, and the press seal difficulty is little like this; Through after follow-up some conventional steps, the surplus pipe in two ends of cutting off, excise the cell-shell blank to blast pipe at last gets final product.But such production technology has gone out UPS with regard to Direct Production.The existence of blast pipe causes the position of cutting blast pipe of UPS to stay cold junction, the appearance different in size of cutting; Formed cold junction size is also just different; And the colour temperature of cold junction and inner bag is closely bound up, and cold junction is not of uniform size to be caused, and colour temperature is just inconsistent; This makes the performance of UPS with respect to TPS, and is relatively poor relatively.Because TPS does not have by the formed cold junction of excision blast pipe, so its serviceability is more outstanding than UPS.Yet the existing production technology of TPS is extremely complicated, is difficult for large-scale production and realizes.
Summary of the invention
The object of the invention is for a kind of exhaust-pipe-free pulse enable type Metal halogen lamp production method is provided.
The solution that the present invention solves its technical problem is:
Exhaust-pipe-free pulse enable type Metal halogen lamp production method, it may further comprise the steps:
1), prepare the cell-shell raw material, and carry out thermal contraction in the bowl bottom;
2), confirm bowl distance and cold junction after, be left end with this end, carry out a press seal;
3), to the cell-shell deshydroxy, and to annotating mercury, injection ball, discharge electrode, positioning of electrode, blanketing gas, ion envelope in it;
4) the cell-shell right-hand member is carried out two press seals.
As the further improvement of technique scheme, in execution in step 4) in the cell-shell right-hand member carried out two press seals in, can heat-proof device be set in the bowl bottom of this right-hand member, said heat-proof device is the thermal baffle that coincide with this bowl Bottom Shape.
As the further improvement of technique scheme, also comprise step after the said step 4) with the surplus pipe excision of cell-shell raw material.
The invention has the beneficial effects as follows: the present invention carries out thermal contraction in the bowl bottom before cell-shell is carried out two press seals, and this makes the bore of bowl bottom dwindle; And after bore dwindled, near tube wall thickened, and cell-shell can not be out of shape when having guaranteed two press seals effectively; Therefore when producing Metal halogen lamp, need not to insert again blast pipe, so can produce exhaust-pipe-free pulse enable type Metal halogen lamp; And technology is ingenious, and step is simple and easy, can be widely used in to produce exhaust-pipe-free pulse enable type Metal halogen lamp.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Fig. 1 is the structural representation of cell-shell raw material;
Fig. 2 uses the TPS structural representation that the present invention produced.
Embodiment
With reference to Fig. 2, exhaust-pipe-free pulse enable type Metal halogen lamp production method, it may further comprise the steps:
1), prepare cell-shell raw material 1, and carry out thermal contraction in the bowl bottom; Generally, said cell-shell raw material 1 forms for the quartz ampoule manufacturing, can fire through quartz straight tube, perhaps the finished product of buying by specifications cell-shell raw material 1;
2), confirm bowl distance and cold junction after, be left end with this end, carry out a press seal, 2 can not be out of shape at the bottom of the bowl during press seal, guaranteeing to have crackle, stress is as far as possible little, electrode can not oxidation etc.;
3), to cell-shell 11 deshydroxies, and to annotating mercury, injection ball, discharge electrode, positioning of electrode, blanketing gas, ion envelope, wherein said pill in it; Promptly refer to inject corresponding medicaments such as corresponding halide in industry; Let the gaseous environment that has the pole electrical arc discharge of can supplying power in the inner bag, the ion envelope is after having filled mercury, pill, a certain amount of gas, shuts cell-shell; Make cell-shell 11 inner and outside isolated, and conventional UPS does not need the ion envelope.
4), the cell-shell right-hand member is carried out two press seals.
Thermal contraction has multiple form of implementation, and the quartz ampoule internal diameter at 2 places dwindles and gets final product at the bottom of letting bowl, for example takes such mode: heat at the bowl end 2 to cell-shell 11, at the bottom of treating bowl 2 burn ripe after, just arrange a pinch roller to come alongside, the quartz ampoule internal diameter at 2 places dwindles at the bottom of making bowl; Likewise, 2 can not be out of shape at the bottom of the bowl in the time of guaranteeing press seal, crackle can not be arranged, stress is as far as possible little, and electrode can not oxidation etc.
Further as preferred embodiment, in execution in step 4) in cell-shell 11 right-hand members are carried out two press seals in, can heat-proof device be set at the bowl place, the ends 2 of this right-hand member, said heat-proof device is the thermal baffle that coincide with this bowl Bottom Shape.When two press seals, burn on the quartz ampoule; At the bottom of part flame can burn bowl along quartz ampoule 2; Add thermal baffle and just can coincide with the bowl end 2 of cell-shell 11, baffle plate closes when heating, prevent flame directly burn bowl at the bottom of 2; So both protected cell-shell 11 to make it not yielding, and can prevent effectively again to cause that because of burning cell-shell 11 hydroxyl rises.
Further, also comprise steps such as surplus pipe excision after the said step 4) with the cell-shell raw material as preferred embodiment.Usually, cut away the two press seals unnecessary part of quartz ampoule later symmetry when a length and a press seal.
