Abstract
The utility model discloses a single end halogen tungsten lamp with spiral support to fix a filament, which comprises a bulb shell, a filament, a filament support, two molybdenum plates, an outer pin and a band iron, wherein the filament support is of spiral shape and is fixed on the upper end of the bulb shell by a hollow clip made up of two corresponding walls of the bulb shell hollowing inside, the middle part of the filament is suspended on the spiral support, two end feet of the filament are respectively connected with the two molybdenum plates, the two molybdenum plates are respectively connected with two outward feet of the clip. With employment of the spiral shaped loop as support for fixing the filament, the spiral shaped loop is simple in structure, convenient for manufacture, low in cost and light in weight, which is employed with ready hardware. The spiral loop structure is of better intensity compared with the filament, which is largely decreased in crafts when fixing the spiral loop at the hollow clip part of the bulb shell, so that manufacture cost is largely decreased, halogen tungsten lamp quality is guaranteed and production efficiency is improved.
Description
Technical field
The utility model relates to single-ended tungsten halogen lamp, specifically relates to a kind of single-ended tungsten halogen lamp with the helical stent anchored filament.
Background technology
In the prior art, single-ended tungsten halogen lamp, generally comprise that cell-shell, filament, filament support, folder are flat, molybdenum sheet and outer pin, yet, there is the single-ended tungsten halogen lamp of a kind of recessed folder formula then to omit filament support, being it makes shape to the cell-shell sunken inside with two symmetrical on cell-shell place's walls, is used for the clamping filament, as the single-ended tungsten halogen lamp of recessed folder formula that is adopted in the Chinese invention patent 97190332.8 disclosed a kind of " reflector lamp ".Though its advantage can be omitted filament support, but owing to adopt the version of cell-shell indent clamping filament, filament clamping rightly that will the children is thin is firm, can not make filament breaking again, but need a whole set of rigorous processing technology to cooperate, cause the technology difficulty when producing bigger, need special process equipment support, cause the increase of production cost.
The utility model content
The purpose of this utility model provides a kind of manufacturing cost and tungsten halogen lamp with the helical stent anchored filament easy to assembly of reducing.
The purpose of this utility model is to realize by following technical scheme: a kind of single-ended tungsten halogen lamp with the helical stent anchored filament comprises cell-shell, filament, filament support, molybdenum sheet, outer pin and presss from both sides flat; It is characterized in that: described filament support is a helical form, is made the upper end that is clamped to cell-shell to the recessed folder portion of cell-shell sunken inside by two symmetrical on cell-shell place's walls; Hang on helical stent at the middle part of filament, and the two ends wire foot of filament connects two molybdenum sheets respectively, and two molybdenum sheets are drawn two outer pins with the flat place of folder respectively again and are connected.
Filament support described in the utility model adopts helical coil, and the axis of this helical coil is parallel with the axis of cell-shell, and filament is hung the bottom at helical coil.
The utility model can be done following improvement: the bottom of described filament support has the helical heater suspension ring, the diameter of described filament suspension ring is less than the diameter of helical coil, its axis is vertical with the axis of described helical coil, and hang on these filament suspension ring at described filament middle part.
The utility model can also be done following improvement: the bottom of described filament support has the filament suspension hook, and hang on this filament suspension hook at described filament middle part.
Filament support described in the utility model is made by tungsten, molybdenum refractory metal or alloy.
Cell-shell described in the utility model is made by quartz glass.
The utility model provides a kind of tungsten halogen lamp with the helical stent anchored filament adopts the support of spiral coil as anchored filament, spiral coil simple in structure, easily manufactured, cost is low and light weight, can select ready-made hardware for use; Spiral helicine loop construction has the intensity more much better than filament, and the technological requirement when being fixed in the recessed folder portion of cell-shell can reduce greatly, can effectively reduce production costs, and can guarantee the tungsten halogen lamp quality again and helps enhancing productivity.
