Abstract
The utility model provides an improved single-end halogen tungsten bulb, which comprises a bulb shell, filament, molybdenum sheets, plywood, and lamp feet. The utility model is characterized in that the beading on the bracket is arranged on the upper part of the plywood that is connected with the bulb shell; the bracket hangs the filament and fixes the filament in the sealed bulb shell, the two molybdenum sheets with lamp feet is arranged in the lower end of the plywood and is respectively connected with the molybdenum filaments at both sides of the filaments. The utility model has the advantages of simple and firm structure, easy manufacturing, and avoiding the influence of the impure gas discharged by the beading on the filament under high temperature state, thus improving the brightness effect and service life of the bulb.
Description
Affiliated technical field
The utility model relates to bulb, particularly a kind of improved single end tungsten halogen lamp.
Background technology
Single end tungsten halogen lamp commonly used at present generally has low voltage bulb (36 volts following) and high voltage lamp (more than 110 volts).The low voltage bulb filament is shorter, and general lead-in wire with the filament two ends directly is welded on the molybdenum sheet just can.High voltage lamp at first will be fixed on several molybdenum filaments during manufacturing and make a support on the bead because filament is longer, with this support filament is hung up then to be fixed in the cell-shell.Experimental results show that: bulb produces high temperature when lighting, bead under the condition of high temperature in inner wall and the cell-shell will discharge a certain amount of foreign gas in varying degrees, some gas can quicken the aging or oxidation of filament, thereby influences the useful life of bulb to a certain extent.
Summary of the invention
In order to solve the problem that prior art exists, the utility model provides a kind of improved single end tungsten halogen lamp, this bulb places the bead on the support in the clamping plate, can avoid like this discharging the influence of foreign gas to filament on condition of high temperature lower-glass pearl, thus the light efficiency and the useful life of improving bulb.
Above-mentioned task realizes by this way: a kind of improved single end tungsten halogen lamp, comprise cell-shell, filament, molybdenum sheet, clamping plate, lamp base, it is characterized in that the bead on the support places in the clamping plate top that is connected with cell-shell, support is hung up filament and is fixed in the cell-shell of sealing, and two molybdenum sheets of band lamp base place in the clamping plate lower end and are connected with the molybdenum filament at filament two ends respectively.
Described support is to be fixed in the middle of the bead and to be constituted by several molybdenum filaments.
The utility model is to make like this: at first in the middle of the equidistant bead that is pressed in fusing of several molybdenum filaments, just become a support after the cooling, lamp base is welded on the molybdenum sheet, on support, hang up filament then, the molybdenum filament at filament two ends is welded on the molybdenum sheet of band lamp base, at last the support that hangs up filament and the band lamp base the molybdenum sheet clamp in cell-shell and clamping plate, exhaust is sealed just becomes the utility model.
From said structure and use principle as seen: the utility model is simple in structure firmly, since this bulb bead is placed in the clamping plate, can avoid discharging the influence of foreign gas to filament on condition of high temperature lower-glass pearl, thus the light efficiency and the useful life of improving bulb.
Description of drawings
Below in conjunction with accompanying drawing structure of the present utility model is described further:
Fig. 1 is the schematic diagram that concrete structure of the present utility model is longitudinally analysed and observe.
Embodiment
As shown in Figure 1, cell-shell 1 of the present utility model is sealing around, the cylindrical shape cell-shell that the lower end is connected with clamping plate 6, the bead 4 of support 3 place in clamping plate 6 tops that are connected with cell-shell 1, support 3 is hung up filament 2 and is fixed in the cell-shell 1, and two molybdenum sheets 5 of band lamp base 7 place in clamping plate 6 bottoms and are connected with the molybdenum filament at filament 2 two ends respectively.
The utility model is applicable to various single-ended high pressure tungsten halogen lamps.
