CN2802720Y - Snag-shape single-end halogen bulb - Google Patents

Abstract

The utility model discloses a hook wire-shaped single-end halogen bulb which comprises a bulb casing, lamp feet, molybdenum foil and a filament arranged in the bulb casing, wherein filament feet on both ends of the filament are separately welded with two pieces of molybdenum foil which is separately welded with two lamp feet, a hook is arranged in an exhaust pipe on the bulb casing, and a hook head of the hook extends into the bulb casing and hooks the filament for forming the supporting point of the filament. The structure proposes fire-new conception, has simple structure, overcomes every disadvantage of traditional single-end halogen bulbs, improves the service performance of bulbs, saves power consumption, increases the output of light and the service life of the bulb, saves a large number of raw and auxiliary materials, reduces cost and is the developing direction of electric light source products.

Description

A kind of snag shape single end halogen bulb

Technical field

The utility model relates to electric light source products, particularly improves the based on halogen bulb of filament supporting construction.

Background technology

Structure relative complex in the traditional high pressure single end halogen bulb, its cell-shell, the form of employing glass supporter filament supports, such structure, the part of required assembling is many, in manufacture process, expends wide variety of materials, and production cost is higher relatively.And the part quality in the cell-shell requires also high, must reach the requirement of electron tube, otherwise, will have a strong impact on the photoelectric parameter and the serviceability of bulb.Problems such as traditional product complex structure, to consume material many, and the input of labor input is many, and manufacture process is loaded down with trivial details are that we are badly in need of solving.

The utility model content

The purpose of this utility model is the weak point that overcomes above-mentioned conventional art, propose a kind of simple in structure, save material, snag shape single end halogen bulb that photoelectric properties are good.

The technical solution of the utility model is: a kind of snag shape single end halogen bulb, include cell-shell, lamp base, be loaded on molybdenum foil, filament in the cell-shell, the two ends wire foot of filament welds with two molybdenum foils respectively, two molybdenum foils weld with two lamp bases respectively again, in the blast pipe on the cell-shell hook is housed, the gib head of hook stretches in the cell-shell and with the filament hook and rises, and forms the strong point of filament.Further, be fixed on the cell-shell for making hook, hook is made by molybdenum filament, its upper end coiled, and be loaded in the blast pipe that port narrows.For preventing the filament short circuit, increase the spacing between the hook filament, hook is the double hook shape with two gib heads in order to an end of hook filament.

Such design has tangible advantage: only need hook in the cell-shell, just the filament support fixation can have been saved material greatly, make the production assembling become simpler; Improved the serviceability of bulb, energy savings has improved the output of light and the useful life of bulb.Can more reasonably control atmosphere in the cell-shell, reduce the venting of metal parts, guarantee vacuum degree.

Embodiment

Referring to Fig. 1 and Fig. 2, the based on halogen bulb of present embodiment mainly is made of cell-shell 1, filament 2, molybdenum foil 3, lamp base 4, blast pipe 5, and special feature is that thin molybdenum filament is turned to hook 6, a spirality that the coiled bore is bigger of hook 6, the other end is organized into the double hook shape with two gib heads.With the upper end is helical form, and the lower end is that the hook 6 of double hook shape is packed in the blast pipe 5 of cell-shell 1.Spiral helicine one is fixed in the blast pipe 5, and the gib head 61 of double hook shape stretches in the cell-shell 1, forms hook.Be fixed hook 6, the port of blast pipe 5 is the collapsed shape of inner wide and outer narrow, and contraction mouth just in time can limit helical form one end of hook 6, and hook 6 can not be got loose or swing.Two wire foot of filament 2 is welded in respectively on two molybdenum foils 3, and molybdenum foil 3 is welded in respectively again on two lamp bases 4, forms current path.When assembling, filament 2 middle parts that weld are hung on the hook 6, and hook 6 is killed, filament 2 can not be fallen down.Molybdenum foil 3 carries out clamp with cell-shell 1, and lamp base 4 is outer lead wires.After bulb after so making carries out exhaust and charges into protective gas, formed the utility model single end halogen bulb.

Certainly, only enumerated a kind of preferred implementation here, the protection category that other is equal to, structure roughly the same all should belong to this patent repeats no more here.

Claims (3)

1, a kind of snag shape single end halogen bulb, include cell-shell, lamp base, be loaded on molybdenum foil, filament in the cell-shell, the two ends wire foot of filament welds with two molybdenum foils respectively, two molybdenum foils weld with two lamp bases respectively again, it is characterized in that: in the blast pipe on the cell-shell hook is housed, the gib head of hook stretches in the cell-shell and with the filament hook and rises, and forms the strong point of filament.

2, based on halogen bulb according to claim 1 is characterized in that hook made by molybdenum filament, its upper end coiled, and be loaded in the blast pipe that port narrows.

3, based on halogen bulb according to claim 1 is characterized in that an end of linking up with in order to the hook filament is the double hook shape with two gib heads.
