Abstract
The utility model discloses a wick electrode positioning filament which is characterized in that: the wick electrode positioning filament comprises a quartz tube; a wick lead, a molybdenum piece and an electrode head are arranged successively in the quartz tube; the middle end of the wick lead is buckled into W shape; the size for the upper and lower ends of the W-shaped wick lead is less than the diameter of the quartz tube; and centralized positioning of the electrode head can be finished accurately and fast without special flaring, thus guaranteeing the consistency of a lamp and improving the stability of the lamp. The wick electrode positioning filament disclosed by the utility model has a simple structure and can perform accurate positioning for the wick electrode.
Description
Technical field
The utility model relates to a kind of manufacturing equipment of optoelectronic device, particularly a kind of wick positioning of electrode silk.
Background technology
Short arc superhigh intensity discharge lamp is the HID light source of electrode spacing less than 10mm, is widely used in the directional lighting device with higher brightness and uniformity requirement, need cooperate with certain optical systems usually and realize the specific illumination purpose.For example be used for the superhigh pressure xenon lamp of cinematographic projector and searchlight, the superhigh pressure Xenon gas metallic halogen lamp of automobile front; Superhigh pressure Metal halogen lamp, xenon lamp and the mercury lamp of the illumination of stage video display; Need and laser pumping, Medical Devices HID light source that optical system is used, and the non-illumination HID light source etc. that utilizes ultraviolet, infrared radiation through beam splitting system.The basic structural feature of this type light source is the bubble pipe of adopting quartz glass material, utilizes the molybdenum foil of weld metal electrode and lead-in wire and quartz glass sealing by fusing to form airtight discharging chamber.Its common technique characteristic is that electrode spacing needs accurately control,, need guarantee as accurate localization electrode for this reason.
The utility model content
Goal of the invention: to the deficiency of prior art, the utility model discloses a kind of can pinpoint wick positioning of electrode silk.
Technical scheme: the utility model discloses a kind of wick positioning of electrode silk, it is characterized in that, comprise quartz ampoule, the wick lead-in wire, molybdenum sheet and the electrode tip that are arranged in the quartz ampoule and connect successively.
The middle-end of said wick lead-in wire is converted into the W type, and the upper and lower side size of the wick lead-in wire of W type is small in the quartz ampoule internal diameter, need not special frock can realize accurately and fast centralized positioning of electrode tip, has guaranteed the consistency of lamp, has improved the stability of lamp.
Beneficial effect: the disclosed a kind of wick positioning of electrode silk of the utility model, simple in structure, can accurately locate the wick electrode.
Description of drawings
Accompanying drawing 1 is the structural representation of wick positioning of electrode silk.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to explain.
The utility model discloses a kind of wick positioning of electrode silk, it is characterized in that, comprise quartz ampoule 4, the wick lead-in wire 1, molybdenum sheet 2 and the electrode tip 3 that are arranged in the quartz ampoule 4 and connect successively.
The middle-end of said wick lead-in wire 1 is converted into the W type, and the upper and lower side size of the wick lead-in wire 1 of W type is small in quartz ampoule 4 internal diameters, need not special frock can realize accurately and fast centralized positioning of electrode tip, has guaranteed the consistency of lamp, has improved the stability of lamp.
The curved overall width of wick lead-in wire W is small in the quartz ampoule inwall, and guarantees that the lead-in wire bottom is in the curved center of W, limit all degrees of freedom like this after, guaranteed that molybdenum sheet and electrode tip are in the center of quartz ampoule.
The utility model provides a kind of thinking and method of wick positioning of electrode silk; The method and the approach of concrete this technical scheme of realization are a lot; The above only is the preferred implementation of the utility model, should be pointed out that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model, and all available prior art of each part not clear and definite in the present embodiment realizes.
