Abstract

The invention discloses a four-core column double-circle (2C) lamp tube, which can prolong the service life of a double-circle lamp tube. Four core columns are arranged in four lamp tube heads of two 2C lamp tubes. Eight outer conducting wires on the four core columns are connected with eight copper pins on a plastic sleeve head. The eight copper pins are divided into two groups, and are arranged on the plastic sleeve head. A four-wire socket is plugged into the four copper pins of one group on the plastic sleeve head to light a group of tungsten filaments up. After the lamp tube is on for a certain time, if electronic powder on the group of tungsten filaments is exhausted and cannot be lighted up, the four-wire socket is unplugged and then plugged into the four copper pins of the other group to continue lighting the lamp tube up. The four-core column double-circle (2C) lamp tube prolongs the service life of the lamp tube, saves resources and is transformed simply.

Description

Four-limbed dicyclo fluorescent tube (2C fluorescent tube)

Affiliated technical field

The present invention relates to a kind of electric light source technology, especially relate to a kind of dicyclo fluorescent tube that has four stem stems.

Background technology

Current dicyclo fluorescent tube has two stem stems, and two Dumet wire on each stem stem connect a tungsten filament, scribble electronic powder on tungsten filament, and when tungsten filament heating, electronic powder sends electronics, and in the time that electronic powder exhausts, lamp just can not be lighted.The double filament energy saving lamp with diverter switch (ZL200710153930.0) that I have authorized.

Summary of the invention

When exhausting, electronic powder just makes the deficiency of scrapping in order to overcome existing dicyclo fluorescent tube, the invention provides a kind of dicyclo fluorescent tube that has four stem stems, this four-limbed dicyclo fluorescent tube, in the time that the tungsten filament electronic powder on two stem stems wherein exhausts, is lighted with the tungsten filament on other two stem stems.

The technical solution adopted for the present invention to solve the technical problems is: in four the fluorescent tube heads of dicyclo fluorescent tube that use at present, four stem stems are installed, a tungsten filament of two inner guide wire welding on a stem stem, the outer seal wires of on four stem stems eight connect the eight piece copper pins of plastics on pullover, eight copper pins are divided into two groups, and to be arranged in plastics pullover upper, and two groups of copper pins are arranged on respectively endocyclic position and the outer ring position of fluorescent tube.Four line sockets of current common use connect ballast, the bright one group of tungsten filament of one group of four copper pin mark on four line sockets reeve plastics are pullover.After lamp tube starting a period of time, as the electronic powder on one group of tungsten filament exhausts and can not light, turn off after power supply, extract four line sockets of plastics on pullover, four line sockets are inserted into the pullover one group of other four copper pin of plastics, continue to light.

The invention has the beneficial effects as follows, extended the useful life of fluorescent tube, the present invention transforms simply, economizes on resources.

Embodiment

In Fig. 1, in four fluorescent tube heads of two ring shaped lamps (2C fluorescent tube), four stem stems (5) are installed, eight outer seal wires on four stem stems connect the eight copper pins (4) on plastics pullover (3), eight copper pins be divided into two groups be arranged in plastics pullover on, in eight copper pins four are that one group of plastics that are arranged on fluorescent tube endocyclic position is pullover upper, eight copper pins other four be one group of plastics that are arranged on the outer ring position of fluorescent tube pullover on.There is the bridging (1) that connects two tubes at two ring shaped lamps (2) mid portion, put up a bridge the internal gas of two tubes can be circulated.

In embodiment illustrated in fig. 2, eight inner guide wires on four stem stems (5) connect four tungsten filaments (6), and in four stem stems, two stem stems at diagonal angle are one group of four copper pin of connection (4).In order to prevent that stem stem from contacting and opening circuit with many lines of copper pin, use RVV to connect.

Claims

1. a four-limbed dicyclo fluorescent tube, in each fluorescent tube head of dicyclo fluorescent tube, a stem stem is installed, on two inner guide wires of a stem stem, weld a tungsten filament, outer seal wire on stem stem connects the four piece copper pins of plastics on pullover, it is characterized in that: in four fluorescent tube heads of dicyclo fluorescent tube, four stem stems are installed, the outer seal wires of on four stem stems eight connect the eight piece copper pins of plastics on pullover, and eight copper pins are divided into two groups, and to be arranged in plastics pullover upper, and wherein one group is connected with four line sockets; The bright one group of tungsten filament of one group of four copper pin mark on four line sockets reeve plastics are pullover; When after lamp tube starting a period of time, as the electronic powder on one group of tungsten filament exhausts and can not light, extract four line sockets of plastics on pullover, four line sockets are inserted into the pullover one group of other four copper pin of plastics, continue to light.

2. Ju four-limbed dicyclo claimed in claim 1 fluorescent tube, is characterized in that: stem stem uses RVV to be connected with the line of copper pin.
