Abstract

The invention relates to the electric light source technology. The invention provides a double-filament ceiling lamp. The ceiling lamp is characterized in that two core columns are arranged in a ring-shaped tube; three Dumet wires pass through each core column; two tungsten wires are welded on the three Dumet wires; four outgoing wires on a fluorescent lamp ballast are connected with a four-wire socket; the four-wire socket is connected with four of six copper pins; and when the lamp can not be lightened as the electron powder on one tungsten wire is used up, the four-wire socket can be pulled out and inserted into four of the other six copper pins to lighten the other tungsten wire. The double-filament ceiling lamp has the following beneficial effect: the service life of the tube can be lengthened on the basis of additional extremely-low cost investment, so the resources can be saved.

Description

A kind of pair of filament ceiling lamp

Technical field

The present invention relates to a kind of electric light source technology, especially relate to a kind of annular lamp tube that is mainly used in ceiling light.

Background technology

Current ceiling light annular lamp tube has two stem stems, and two Dumet wire on each stem stem connect a tungsten filament, scribble electronic powder on tungsten filament, and during tungsten filament heating, electronic powder sends electronics, and when electronic powder exhausts, lamp just can not be lighted.The double filament energy saving lamp with diverter switch (patent No. ZL200710153930.0) that I have been authorized.

Summary of the invention

In order to overcome existing fluorescent tube, when electronic powder exhausts, just make the deficiency of scrapping, the invention provides the annular lamp tube of a kind of pair of filament, the annular lamp tube of this pair of filament, when one group of tungsten filament electronic powder wherein exhausts, is used another group preparation tungsten filament.

The technical solution adopted for the present invention to solve the technical problems is: on two stem stems in annular lamp tube, each stem stem has three Dumet wire to pass through, and welds two tungsten filaments on three inner guide wires.Six roots of sensation copper pin on the six roots of sensation on two stem stems seal wire connection outward plastics are pullover.Four outlets on fluorescent lamp ballast connect four line sockets, four copper cushion holes of inserting above four line sockets in six roots of sensation copper pin on plastics are pullover, when the electronic powder on one group of tungsten filament exhausts and can not light, extract plastics pullover, thereby the four copper pins of another group in six roots of sensation copper pin are inserted to four line sockets, light another root tungsten filament.On both sides, four copper cushion holes, being respectively provided with two the insides does not have the copper cushion hole of energising, facilitates four line sockets can inject the six roots of sensation copper pin of plastics on pullover.

The invention has the beneficial effects as follows, as long as increase the cost of or two maos, just the useful life of energy prolonging lamp tube, economize on resources.

Embodiment

In Fig. 1, the corresponding four copper pins (2) that inject on fluorescent tube plastics pullover (3) of four line sockets (1).Ceiling light can not be lighted as electronic powder exhausts after using a period of time.Extract four copper pins (2) that four line sockets (1) inject another group.

In embodiment illustrated in fig. 2, on a stem stem (4), there are three Dumet wire to pass through, on three Dumet wire, weld two tungsten filaments (5).The upper six roots of sensation copper pin of the outer seal wire pullover with plastics (3) of the upper six roots of sensation of stem stem (4) is connected.

In another embodiment shown in Fig. 3, four outlets on ballast are connected with four the copper cushion holes (6) on four line sockets (1).On (6) two limits, four copper cushion holes, respectively have two copper cushion holes (7), the not energising of the inside, copper cushion hole (7), just in order to facilitate four line sockets (1) can inject the six roots of sensation copper pin (2) on plastics pullover (3).Electronic powder on one group of tungsten filament (5) exhausts and can not light, and extracts four line sockets (1), changes a position and inserts the four copper pins of another group in the upper six roots of sensation copper pin of plastics pullover (3).

Claims

1. a two filament ceiling lamp, in ceiling light housings, fluorescent lamp ballast is installed, annular lamp tube, it is characterized in that: on two stem stems (4) in annular lamp tube, each stem stem (4) has three Dumet wire to pass through, on three inner guide wires, weld two tungsten filaments (5), the outer seal wire of the six roots of sensation on two stem stems (4) connects the six roots of sensation copper pin (2) on plastics pullover (3), four outlets on fluorescent lamp ballast connect four line sockets (1), four in six roots of sensation copper pin (2) on plastics pullover (3) are inserted four line sockets (1) copper cushion hole (6) above, when the electronic powder on one group of tungsten filament (5) exhausts and can not light, extract plastics pullover (3), four copper pins of another group in six roots of sensation copper pin are inserted to four line sockets (1) thus light another root tungsten filament.

2. according to claim 1 pair of filament ceiling lamp, it is characterized in that: on both sides, four copper cushion holes (6), be respectively provided with the copper cushion hole (7) that two the insides do not have energising, facilitate four line sockets (1) can inject the six roots of sensation copper pin (2) on plastics pullover (3).
