Description
Affiliated technical field
The utility model relates to a kind of single-ended tungsten halogen lamp, particularly relates to a kind of single-ended tungsten halogen lamp that presss from both sides recessed anchored filament support.
Background technology
In the prior art, common single-ended tungsten halogen lamp generally comprises cell-shell 1, filament 3, filament support 4, press from both sides flat 5, molybdenum foil 6 and outer pin 7, cell-shell 1 top has exhaust point 2, the bead 41 that filament support 4 is made by quartz glass usually, electrode molybdenum wire 42 and support molybdenum filament 43 are formed, electrode molybdenum wire 42 and support molybdenum filament 43 are fixed on according to certain arrangement regulation and constitute filament support 4 on the bead 41, filament 3 can be hung over according to the length of designing requirement on the filament support 4, make filament support 4 be fixed on the top of folder flat 5 by electrode molybdenum wire 42 and molybdenum foil 6 welding of pressing from both sides in flat 5 then.This structure weak point need to be to make separately complicated filament support 4 and electrode molybdenum wire 42 to be welded on the molybdenum foil 6 its complex manufacturing technology, cost height in folder flat 5.
In addition; the single-ended tungsten halogen lamp of above-mentioned high pressure is when dying of old age; regular meeting produces arc discharge between two electrodes; cause Lamp bulb case 1 explosion; therefore for the sake of security, the fuse 8 of often need in the work loop of lamp body inside/outside, connecting, the single-ended tungsten halogen lamp that the fuse 8 of series connection is positioned at lamp body is called explosion-proof single-ended tungsten halogen lamp; its weak point is exactly to make the manufacture craft of former complexity more complicated, and cost is higher.
The utility model content
The purpose of this utility model is exactly in order to provide a kind of explosion-proof effect that can reach again can simplified processing process and adapt to the single-ended tungsten halogen lamp of the recessed anchored filament support of folder that mechanization produces.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of single-ended tungsten halogen lamp that presss from both sides recessed anchored filament support, comprise that cell-shell, filament, filament support, folder are flat, molybdenum foil and outer pin, it is characterized in that: filament support is by recessed the gripping of the folder of at least two on the cell-shell wall, the middle part of filament hangs over the top of filament support, the silk tail at filament two ends directly is connected with the flat interior molybdenum foil of folder, the partial-length of described silk tail imbed folder flat in, and have a filament silk tail at least for not being rolled into double helical seal wire.
The recessed middle and lower part of cell-shell that is symmetricly set in of on the cell-shell wall described in the utility model two folder is near the flat position of folder.
Filament support described in the utility model is made of a support bar at least, and its top has the structure of filament supports, as hook formation, perhaps groove shape structure, perhaps bung flange structure etc., the bottom being direct rod shape by the position of the recessed clamping of folder, is beneficial to the recessed clamping of folder of cell-shell at least; Support bar can be a metallic support rod of being made by resistant to elevated temperatures metal materials such as tungstens, also can be the glass rod of being made by quartz glass or similar material.
Cylindricality glass post that filament support described in the utility model also can be made by a quartz glass or similar material and the metallic support rod that is fixed on the glass column top more than one or are formed, the top of metallic support rod has the structure of filament supports, because the volume of glass post is big than metallic support rod, metallic support rod then processing characteristics is better than glass, therefore both combinations, respectively get the chief, pressed from both sides the part of recessed clamping by cell-shell by the conduct of glass post, the clamping contact-making surface is big, is more conducive to process and improve the steadiness of clamping; By the metallic support rod filament supports, utilize the performance of metal material, the structure of metallic support rod filament supports can have multiple choices, as hook-shaped or bung flange shape etc., and supporting form also can have multiple choices, as the single pole supporting form, perhaps two bar supporting forms, perhaps many bars supporting form etc.Can select according to the requirement for height of filament design length and tungsten halogen lamp, under the situation of cell-shell equal height, support bar can be designed to multiple shape,, can elongate filament length by design applicable multiple power.
The utility model can also further improve: described glass rod has two planes of symmetry, and perhaps the glass post is the plane at the position that is held, and to increase the clamping contact-making surface, improves the steadiness of clamping.
In order to improve the steadiness of filament support, the flat internal fixation of folder can be stretched in the lower end of filament support, perhaps exhaust point internal fixation is stretched on the top of filament support, perhaps both adopt simultaneously, be that the filament support middle part is by the recessed clamping of the folder of cell-shell, the flat internal fixation of folder is stretched in the lower end, and exhaust point internal fixation is stretched in the upper end.
Filament silk tail described in the utility model is not meant that for being rolled into Double-spiral a tail can be straight or approaching straight seal wire, can be single-screw seal wire yet.Described filament silk tail can be an end for not being rolled into double helical seal wire, also can be that two ends all are not to be rolled into double helical seal wire, and the described double helical silk tail seal wire diameter that is not rolled into be between 15～80 μ m.
The beneficial effects of the utility model are:
(1) abandoned traditional filament support fixed form of the bead+electrode molybdenum wire+support molybdenum filament of employing usually, and filament is connected between two electrode molybdenum wires, electrode molybdenum wire is connected with molybdenum foil as the strutting piece of filament support and by the flat relation that is fixedly coupled of folder, filament support is reduced to a support bar or a glass post+support bar, the recessed anchored filament support of folder that in the course of processing, forms by cell-shell, the silk tail of filament directly is connected between two molybdenum foils, reduced the member of filament support, make it more to adapt to the requirement that mechanization is produced, not only help enhancing productivity, improve light efficiency, also reduced cost simultaneously.
(2) because filament support only plays the supporting role of filament, no longer play electrode, therefore not having electric current passes through filament support, the silk tail of filament directly is welded on the molybdenum foil, and have at least the filament silk tail tungsten filament of an end not to be rolled into Double-spiral, because of it is sayed with respect to the Double-spiral filament, its quality is much smaller under the identical situation of the length of imbedding the flat part of folder, the evaporation of tungsten filament material therefore can be faster in capillary, electric arc is extinguished earlier, and the response time of intrinsic safety is also very fast, therefore, the problem that can avoid the single-ended tungsten halogen lamp of high pressure easily arc discharge to take place when dying of old age and set off an explosion need not to add fuse and just has explosion-proof security performance in lamp body.
(3) because filament silk tail seal wire diameter requires less than 80 μ m, thereby can directly fire by the filament same material and form, thus applicable greater than 80V, and power is the 20-200W halogen tungsten bulb, but is not precluded within other discharge lamp, the use of incandescent lamp.
