Abstract

The invention discloses a double-filament ceiling lamp which has the advantage of prolonging life of the conventional lamp using a 2D lamp tube. Three dumet wires pass through each of two core columns of the 2D lamp tube; and two tungsten filaments are welded with three inner guide wires. Six outer guide wires on the two core columns are connected with six copper pins on a plastic head sleeve. Four outgoing lines on a ballast of a fluorescent lamp are connected with a four-wire socket; and four of the six copper pins on the plastic head sleeve are inserted into copper pin plug holes on the four-wire socket. When a group of tungsten wires cannot be lighted up because of exhaust of electronic powder of the tungsten wires, the copper pins are pulled out for use, and the four copper pins in another group are inserted into the four-wire socket to light up another group of tungsten wires. Through the ceiling lamp, cost performance of the 2D lamp tube is improved and resources are saved.

Description

Two filament lamp affixed to the ceilings

Affiliated technical field

The present invention relates to a kind of electric light source technology, especially relate to a kind of 2D fluorescent tube that is mainly used in lamp affixed to the ceiling.

Background technology

Present lamp affixed to the ceiling 2D fluorescent tube has two stem stems, and two Dumet wire on each stem stem connect a tungsten filament, scribble the electronics powder on the tungsten filament, and the electronics powder sends electronics during the tungsten filament heating, and lamp just can not be lighted when the electronics powder exhausts.The double filament energy saving lamp (ZL200710153930.0) of the band change-over switch that I have authorized.

Summary of the invention

Just make the deficiency of scrapping in order to overcome traditional fluorescent lamp tube when the electronics powder exhausts, the invention provides the 2D fluorescent tube of a kind of pair of filament, the 2D fluorescent tube of this pair filament uses another group preparation tungsten filament when wherein one group of tungsten filament electronics powder exhausts.

The technical solution adopted for the present invention to solve the technical problems is: on two stem stems of 2D fluorescent tube, each stem stem has three Dumet wire to pass through, two tungsten filaments of welding on three inner guide wires.The outer seal wire of the six roots of sensation on two stem stems connects the six roots of sensation copper pin of plastics on pullover.Four outlets on the fluorescent lamp ballast connect four line sockets, four insertions in the six roots of sensation copper pin on copper cushion hole above four line sockets and plastics are pullover, exhaust and to light as one group of tungsten filament electronics powder, extract four copper pins on four line sockets, insert four line sockets with four copper pins of another group and light another group tungsten filament.

The invention has the beneficial effects as follows, on four line sockets that use at present, bore two holes, pullover the going up of the plastics that use increases by two copper pins at present, as long as the change stem stem is the service life of energy prolonging lamp tube just, the present invention transforms simply, as long as increase the cost of 0.2-0.5 unit, improved the cost performance of fluorescent tube, saved resource.

The specific embodiment

In Fig. 1, the outer seal wire of the six roots of sensation in the 2D fluorescent tube (4) on two stem stems (9) connects six roots of sensation copper pin (2), (3), and copper pin (2), (3) are arranged on the plastics pullover (1).

In example shown in Figure 2, four outlets of ballast (5) connect four the copper cushion holes (6) on four line sockets (8).Go up brill two copper cushion holes (7) at four line sockets (8) that use at present, the inside, copper cushion hole (7) does not have the electric wire energising, just the insertion of copper pin (3) for convenience.Four the copper cushion holes (6) on reeve four line sockets of the copper pin (3) on the plastics pullover (1) (8), other two copper pins (2) are inserted on the outside of four line sockets (8).Exhaust and to light when the 2D fluorescent tube uses the electronics powder on a period of time one group of tungsten filament, after turning off power supply, extract the four copper pins (3) on four line sockets (8), again six copper cushion holes (6), (7) are injected in six roots of sensation copper pin (2), (3), light another group tungsten filament.

In another example of Fig. 3, a stem stem (9) has three Dumet wire to pass through, three inner guide wires connect two tungsten filaments (10), two parallel welding of tungsten filament on stem stem are not to connect on same straight line of three inner guide wires, because two tungsten filaments link together, the tungsten filament heat of lighting passes to the preparation tungsten filament fast, can accelerate the electronics powder evaporation on the preparation tungsten filament, two tungsten filaments separate, and parallel connection can reduce the heat transferred preparation tungsten filament of lighting tungsten filament.The outer seal wire of the six roots of sensation on two stem stems connects six roots of sensation copper pin (2), (3) on the plastics pullover (1).Four copper pins (3) in six roots of sensation copper pin (2), (3) connect four the copper cushion holes (6) on four line sockets (8), and one group of tungsten filament is wherein lighted.After fluorescent tube uses a period of time, when exhausting, can not light in the electronics powder, and another group tungsten filament is lighted in four copper cushion holes of using four copper pins of another group to connect on four line sockets.

Claims
