Description
Technical field
The utility model relates to a kind of spot light assembly, especially relates to a kind of spot light electrode molybdenum slice assembly.
Background technology
Super-pressure spot light is a kind of gas-discharge lamp, is filled with mercury and inert gas in lamp, and during work, the interior mercury vapour of lamp is in super-pressure state.The brightness of super-pressure spot light is larger, is applied in the fields such as liquid crystal projection apparatus and searchlight more.
In super-pressure spot light, electrode molybdenum slice assembly is enclosed in the both sides of discharge tube with air tight manner, there is following defects:
Solder technology aspect between electrode and molybdenum sheet, in existing technology, the solder technology of tungsten electrode and molybdenum sheet is mainly traditional electrode resistance welding, this technology adopts upper and lower tungsten electrode electric discharge welding, being about to thick tungsten bar and molybdenum sheet is pressed between two electrodes, and imposing electric current, resistance heat effect that workpiece contact-making surface and adjacent domain produce is heated fusing or mecystasis to utilize electric current to flow through, and makes it to form a kind of method of metal combination.Due to the fusing point gap between tungsten material and Mo large (molybdenum fusing point 2610 degree, tungsten fusing point 3410 degree), traditional electric resistance welding mode welding energy is difficult to accurately control, cannot make to exist mutual parent to moisten between bi-material, cannot form the effective one-tenth state that dissolves each other, its welding difficulty is larger, and the product quality after welding is difficult to be guaranteed, and weldering or rosin joint easily occurred, there is oxidation in bond pad locations, the uniformity of weld strength is very poor.And this spot welding mode is manual spot welding, inefficiency, single weld interval is long, 1pcs/10s.
Molybdenum sheet bearing strength aspect, in prior art, sealing-in molybdenum sheet is mainly divided into two kinds, and a kind of is smooth shape molybdenum sheet, in discharge tube assembling process, must be by the vertical placement positioning of subassembly product, electrode is in upper end position, due to electrode own wt, easily there is bending in molybdenum sheet position, cannot support electrode, can not meet its linearity requirement, affected subsequent production.Another kind of is bending or arc molybdenum sheet, and the molybdenum sheet of this shape has certain rigidity, and has supporting role, but the degree of arc or bending is not clearly defined, if molybdenum sheet arc or bending degree are too little, the carrying effect of molybdenum sheet can obviously reduce, and cannot play a supporting role to electrode; If molybdenum sheet arc or bending degree are too large, can cause in the follow-up press seal process of assembly and between glass tube, have obvious gas line, both cannot combine closely to make it, have a strong impact on press seal assembly quality.
Aspect, lead-out wire location, in prior art, lead-out wire is generally straight rod-shaped design, does not have expliciting the position to support, in the process of encapsulation discharge tube, because lead-out wire is with gap excessive between quartz ampoule, be difficult to keep assembly with the coaxial state of quartz ampoule, cause electrode space deflection, pole span produces obvious deviation, the luminous mass of its discharge lamp is reduced, greatly shorten its service life.
Utility model content

The spring that described emission electrode is set in plug front end by plug and welding forms.
The peak with heading of described plug front end is partly club shaped structure routinely, circle head-like structure or bullet-shaped structure.
Described sealing-in molybdenum sheet is arcuate structure or mountain peak shape structure.
The radian of the sealing-in molybdenum sheet of arcuate structure is controlled at 1.2-2.8rad.
The peak angle of the sealing-in molybdenum sheet of mountain peak shape structure is 80-160 °, and peak heights is 0.1-0.75mm.
Described lead-out wire is molybdenum rod lead-out wire, and afterbody is rhombus or hooked shape structure, and middle part is straight-bar or wavy shaped configuration.
Described lead-out wire is arranged in glass tube, and the height of the afterbody of rhombus or hooked shape structure and glass tube internal diameter match, and the height of middle wavy shaped configuration is slightly less than glass tube internal diameter.
Compared with prior art, the utlity model has following advantage:
(1) solder technology aspect: electrode and molybdenum sheet are multiple spot laser weld, by controlling laser energy and bond pad locations and quantity, is uniformly distributed welding energy, avoids weldering or rosin joint, has guaranteed quality and the fastness of spot welding.
(2) molybdenum sheet bearing strength aspect: the arc of employing or peak shape structure, increased the rigidity of molybdenum sheet self, improved the bearing strength of molybdenum sheet, prevent that the electrode causing due to molybdenum sheet bending cannot be supported, and has guaranteed the linearity of component assembling.And to the explicitly calling for of radian and peak angle height, can more accurately control the bearing capacity of molybdenum sheet, make molybdenum sheet aspect carrying and assembling aspect keeps optimized balance.In addition, when guaranteeing bearing strength, can, according to the size of the weight of electrode and molybdenum sheet, molybdenum sheet peak shape be adjusted.If electrode is heavier, molybdenum sheet can be designed to bimodal or three peak shapes, if electrode is lighter, molybdenum sheet can be designed to unimodal shape, flexible and changeable.
(3) aspect, lead-out wire location: lead-out wire end is rhombus or curved hook-shape structure, and wavy shaped configuration can be used according to actual product situation in middle part.The rhombus of afterbody or curved hook-shape structure mainly play positioning and guiding effect in assembling process, can make electrode accomplish quick location, guarantee its exact position in discharge tube, guarantee that light center is not offset, its height dimension should match with actual glass tube internal diameter, and required precision is controlled at 0.1mm, if rhombus or crotch shape height dimension are too small, make excesssive gap between lead-out wire and glass tube, both cannot keep coaxial state, cause electrode skew; If height dimension is excessive, can cause assembly to assemble with glass tube.Therefore need to accurately control precision.In addition, if length component is longer, only depend on the some surface contact structure of afterbody cannot Assurance component before the collimation requirement of termination electrode, consideration adds wavy shaped configuration in lead-out wire stage casing, this waveform height dimension is slightly less than glass tube internal diameter, and precision is controlled at 0.05mm, strengthen its guidance quality, make it more reliable and stable.
