Background technology

As everyone knows, fluorescent lamp need be equipped with ballast and could use, at present, electric ballast on the market is a leap greatly than old-fashioned iron core ballast from aspects such as structure, operation principle, performances, played energy-conservation, volume is little, in light weight, operating voltage range is wide, need not building-out capacitor and starter, actively effect such as increase the service life.But no matter be iron core formula or electronic ballast, driving many fluorescent lamps simultaneously with a ballast works simultaneously, problems such as starting current is big, pulse voltage is high, the fluorescent lamp group influences each other in the whole service process appear easily, as fluorescent tube wherein under the disconnected situation of a head lamp silk, this ballast is cisco unity malfunction just, brings great inconvenience to people's life.

Summary of the invention

Purpose of the present invention is exactly a kind of not only simple in structure, the environmental protection and energy saving that provide for the deficiency that solves prior art, and can make the relatively independent wireless telescopic fluorescent lamps connected with multiple paths of electronic ballasts combination that does not interfere with each other of each fluorescent tube.

The present invention adopts following technical solution to realize above-mentioned purpose: a kind of wireless telescopic fluorescent lamps connected with multiple paths of electronic ballasts combination, comprise ballast shell, ballast binding post and be arranged on ballast shell interior current rectifying and wave filtering circuit, high-frequency oscillating circuits, high-frequency oscillating circuits is connected with the output loading circuit of external some fluorescent tubes, it is characterized in that: be provided with in the described output loading circuit and start electric capacity and be sub-packed in the fluorescent tube corresponding, make that each fluorescent tube is relatively independent not to interfere with each other with it.

As further specifying of such scheme, described ballast binding post comprises input, output and common port, ballast input termination power, a stitch in two stitch of the loading capacitance terminal of several fluorescent tubes interconnects the back as common port and is connected with the ballast common port, and its another stitch is connected with the output of ballast respectively.

The input of described current rectifying and wave filtering circuit also is provided with the power supply input protection circuit of being made up of fuse F1, inductance L 1, L3 and capacitor C 1; Current rectifying and wave filtering circuit comprises the bridge rectifier be made up of diode D1～D4 and filter capacitor C4, the C5 in parallel with this bridge rectifier; AC power provides power supply through output DC behind the rectifying and wave-filtering for high-frequency oscillating circuits.

Described high-frequency oscillating circuits comprises the starting of oscillation circuits for triggering be made up of capacitor C 6 and bidirectional trigger diode DB3, by the half-bridge inversion circuit that two transistors and peripheral circuit thereof are formed, the end of bidirectional trigger diode DB3 links to each other with the base stage of the switching tube Q2 of half-bridge inversion circuit.

Also be provided with abnormal state protection circuit in the described ballast shell, this circuit comprises controllable silicon Q3, resistance R 7 and electrochemical capacitor E3, E4, and electrochemical capacitor E4 links to each other with the base stage of switching tube Q2 by serial connection capacitor C 9.

The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:

1, the present invention adopts the startup electric capacity in the electric ballast is contained in respectively in corresponding many tubes, ballast input termination power, the wherein arbitrary pin of two stitch of fluorescent tube (electric capacity one end is housed) is as public pin, after the public pin of fluorescent tube that needs are connected couples together, be connected with the ballast common port again, and another stitch of fluorescent tube is connected with the output of ballast respectively, make each fluorescent tube separate in use, do not disturb mutually, can alleviate the weight of ballast on the one hand, can also connect many tubes on the other hand more, each fluorescent tube is separate in use, does not disturb mutually, even few dress or the wherein any fluorescent tube of damage, other fluorescent tube is still normally lighted, thereby has improved the life-span of fluorescent lamp.

2, the interchangeability of the fluorescent tube that connects of ballast of the present invention reduces use cost and maintenance cost by force, greatly, and fluorescent tube can be made single-pass or bilateral so that use or install.
