Abstract

The utility model relates to a nonexpendable multi-filament lamp tube. Two or more than two sets of filaments are arranged in both ends of a glass lamp tube housing, and each set of filaments is composed of two corresponding filaments of the both ends of the lamp tube. Nuts which have the same amount with the filament electrodes are arranged on insulating boards of the both ends of the lamp tube, and the filament electrodes are electrically connected with the nuts. The nuts which are connected with the filament electrodes are symmetrically distributed taking the circle center of the insulating board as the center, and the input electrodes of the filaments and the nuts are movably connected with a screw rod. The lamp tube can be used at least twice or more times, when one set of filaments is used each time. While in use, the nuts connected with the set of the filaments are connected with the screw rod, and the set of the filaments is electrically connected with the tube holder through the screw rod. Another set of filaments is used by connecting the screw rod with the nuts of the new set of filaments, with the burning out of the former set of the filaments.

Description

Multi-filament lamp tube

Affiliated technical field

The utility model relates in a kind of fluorescent tube and Multi-filament is housed, the Multi-filament lamp tube that can be used multiple times.

Background technology

At present, known fluorescent tube inside has only two filaments, one first at two ends, behind a filament blow wherein, although the other parts of fluorescent tube are intact, this root fluorescent tube also must be scrapped, though the manufacturing cost ratio of filament in whole fluorescent tube is very low, also can scrap whole fluorescent tube, cause and lose the greater for less because of disintegration of filament; Particularly use the fluorescent tube of electron rectifier, filament is easy to blow without preheating during owing to unlatching, fluorescent tube shortening in useful life.

Summary of the invention

The shortcoming that have only two filaments in order to overcome existing fluorescent tube, can only use once, useful life is not long, the utility model provides a kind of Multi-filament lamp tube, and this Multi-filament lamp tube can repeatedly use than originally having howed the filament more than two, in the useful life of prolonging lamp tube, save use cost.

The technical scheme that its technical problem that solves the utility model adopts is: in the glass shell two ends of fluorescent tube, except that original one group of filament, increase two groups or more filament at least.Increasing by 1 group of filament with straight tube shape below is that example describes.The insulation board of lamp tube ends is made circle, 4 nuts are embedded in respectively in the hole above the insulation board together with filament electrode, nut links to each other with the filament electrode electricity, the nut outer end flushes with insulation board, dentation is made by the edge that contacts with insulation board, 4 nuts are that the center is symmetrically distributed with the insulation board center of circle, and the nut that links to each other with two electrodes of same filament is electrically connected with screw rod in the mode of activity.When using fluorescent tube, every end joins with the nut of two symmetries on two screw rods and the insulation board, and the screw rod filament of lamp tube ends is corresponding, and four screw rods are on the same plane, and the screw rod on the lamp tube ends insulation board inserts base and is electrically connected, and just can normally use.After disintegration of filament, screw rod is connected on the filament and nut of another group two ends symmetry, utilize another group filament, continue to use fluorescent tube.When wherein one of second group of filament burns out, there are a good filament, fluorescent tube also can continue to use as long as lamp tube ends one end is also surplus.At this moment, an end of selecting screw rod wherein to link to each other with the disintegration of filament, with two filaments of this end and connect, copper wire one end is fixed tightly on the nut with screw rod with nut one end with two copper wires.

The beneficial effects of the utility model are: Multi-filament lamp tube described in the utility model is owing to be equipped with many group filaments in the pipe, wherein can enable other filament behind one group of filament blow, the useful life of prolonging lamp tube, can reduce the use cost of fluorescent tube widely, more help promoting further applying of various fluorescent lamps, electricity-saving lamp etc., particularly in the rural area.

Description of drawings

Organigram when accompanying drawing 1 uses second group of filament for the utility model.

Accompanying drawing 2 is the sectional view of the utility model insulation board.

Among the figure: 11,12,13,14 is filament, and 21,22,23,24,25,26,27,28 is nut, and 31,32,33,34 is screw rod, and 41,42,43,44 is nut, and 5 is glass shell, and 6 is metal cap, and 7,8 is insulation board.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified:

In the drawings, in the glass shell of Multi-filament lamp tube (5) two ends, except that original one group (to call first group in the following text) filament (11) and (13) two, also increased by one group of (to call second group in the following text) filament (12) and (14), circle is made in the insulation board of lamp tube ends (7) and (8), nut (21), (22) together with two electrodes and the nut (23) of filament (11), (24) two electrodes together with filament (12) all are embedded in above the insulation board (7), nut (21), (22), (23), (24) forming the square center of circle with insulation board (7) is that the center is symmetrically distributed, two opposite groups nut (21) and (22), (23) and (24) be that the center is symmetrically distributed with the center of circle, wherein nut (21) and (22) symmetry, nut (23) and (24) symmetry; In the same way nut (25), (26), (27) and (28) are embedded in above the insulation board (8) together with two electrodes of filament (13), (14).All nut outer ends flush with the insulation board outside, and dentation is made by the edge that contacts with insulation board.In lamp tube ends, filament (11) is corresponding with (13), and filament (12) is corresponding with (14), and nut (21), (22) and (25), (26) are corresponding, are on the same plane, form a square; Nut (23), (24) and (27), (28) are corresponding, also are on the same plane, form a square.When using fluorescent tube, can use first group of filament (11) and (13) earlier, join with nut (21) and (22) respectively with screw rod (31) and (32), screw rod (33) and (34) join with nut (25) and (26) respectively, again screw rod (31), (32) and screw rod (33), (34) are linked to each other with base, just can normally use.After first group filament has one to burn out, bring into use second group of filament (12) and (14), being about to screw rod (31) and (32) joins with nut (23) and (24) respectively, screw rod (33) and (34) join with nut (27) and (28) respectively, again screw rod (31), (32) and screw rod (33) are linked to each other with base with (34), just can continue to use fluorescent tube.When wherein one of second group of filament has burnt out, as long as the every end of lamp tube ends is also surplus a good filament is arranged, fluorescent tube also can use for the third time.If what burn out for twice is filament (11) and (14), and screw rod (31), (32), (33), (34) are connected on respectively on nut (23), (24), (27), (28) at this moment, at this moment use two copper wires with filament (13) and (14) parallel connection, promptly an end of two copper wires is connected in respectively on nut (27) and (28) with screw rod (33) and (34), and the other end is connected in respectively on nut (25) and (26) with nut (43) and (44).If the every end of fluorescent tube is equipped with the filament more than two, according to the method described above, fluorescent tube can use more than three times at least.
