Description

Low-voltage energy-saving neon lamp

Type belongs to the electric light class, is the technological improvement to the decorative kind lamp device, and its name is called the low-pressure energy-saving neon light.

In the prior art, what neon light was the most frequently used is a kind of high pressure neon light, and its working voltage is up to 10,005 kilovolts, and the high pressure neon light shows following deficiency in actual applications:

1, is easy to generate electrion, poor stability.

2, power consumption is many, and the power consumption of every rice lamp pipe is more than 45W.

3, use very inconvenience, can only use in outdoor and high-altitude, can not be in low latitude and indoor use, this is because its working voltage is too high, the reason of poor stability.

4, complex structure, processing difficulties, the cost height, a transformer can be with 10 fluorescent tubes, but also needs transformer of adapted during 10 fluorescent tubes of less than, and causes unnecessary waste.

The purpose of the utility model design is to avoid above-mentioned the deficiencies in the prior art, and a kind of low-pressure energy-saving neon light is provided, and it is made up of less than inert gas, electrode and the mains supply of 6mmHg post the ballast that the low pressure high frequency can be provided, glass lamp, pressure, and low-pressure energy-saving neon light described in the utility model is simple in structure, easy to manufacture, little power consumption, cost is low, and working voltage is low, safe and reliable, both can install, can use in indoor low latitude again in outdoor high-altitude, very convenient.

To achieve these goals, the utility model can adopt following measure to realize, described low-pressure energy-saving neon light is made up of glass lamp, two electrodes, inert gas and ballast, the pressure that it is characterized in that inert gas in the fluorescent tube is less than the 6mmHg post, two electrodes are respectively the book sheet metal, two inputs of ballast link to each other with civil power, and two outputs link to each other with two electrodes in the fluorescent tube respectively.

To achieve these goals, the utility model can also adopt following measure to realize, two electrodes in the described fluorescent tube can be tubular, also can be taper, and its thickness is all less than 0.6 millimeter.

To achieve these goals, the utility model can also adopt following measure to realize, the output voltage of described ballast is the 700-1600 volt, and frequency is 15-30KHZ.

To achieve these goals, the utility model can also realize in the following way that described ballast is by a bridge circuit D is arranged in the described ballast of rectified current ₁-D ₄Input link to each other with civil power, input again with filter capacitor C ₁, resistance R ₁, capacitor C ₂, diode D ₅And D ₆, and triode BG ₁And BG ₂Link to each other BG ₁Base stage be connected with resistance R ₂With magnetic ring transformer L ₂, emitter stage is connected with resistance R ₄, BG ₂Base stage and resistance R ₃, magnetic ring transformer L ₁Link to each other, emitter stage is connected with resistance R ₅, diode D ₅With D ₆Positive pole be connected in R ₁With C ₂Between, negative pole respectively with BG ₁And BG ₂Base stage link to each other the L of magnetic ring transformer ₁With L ₂The common primary coil of forming transformation gas, L ₃Be secondary coil, L ₃With inductor L ₄Behind the polyphone, resistance R ₆With C ₆After the parallel connection again with L ₃, L ₄And capacitor C ₄Polyphone, fluorescent tube 1 and capacitor C ₅After the parallel connection, an end and C ₄Link to each other the other end and L ₄Connect C ₅＜＜C ₄

For clearer explanation the utility model, the utility model is done further explanation below in conjunction with accompanying drawing:

Fig. 1 is that outward appearance of the present utility model is in conjunction with schematic diagram.

Fig. 2 is the theory structure schematic diagram of ballast described in the utility model.

In conjunction with the embodiments the utility model is done further explanation more below:

Embodiment 1:

Will be at 15 neon light pipes 1 of certain indoor installation, all to install two thin electrodes of thickness taper below 0.6 millimeter 3 in each fluorescent tube 1, the any inert gas 2 of 6 millimetress of mercury with downforce also is housed in each fluorescent tube 1, two electrodes 3 link to each other with two outputs of ballast 4 respectively, two inputs of ballast 4 link to each other with civil power respectively, 220 volts of line voltages, frequency 50HZ, the output voltage 700-1600 volt of ballast 4, frequency 15-30KHZ, ballast 4 is made up of rectification circuit and starting circuit, rectification circuit D ₁-D ₄With C ₁Form current rectifying and wave filtering circuit, civil power is through D ₁-D ₄After the bridge rectifier rectification,, can obtain the DC voltage of about 310 volts of peak values again through C1 filtering.Starting circuit: by R ₁, C ₂, C ₅And D ₆Form, wherein R1 and C ₂Form integrating circuit, when ballast 4 was connected with civil power, integrating circuit began charging, works as C ₂On voltage reach diac D ₆Break over voltage the time, trigger D ₆Conducting, C ₂Through diac D ₆To triode BG ₁Discharge forms base current, thus excitation BG ₁Conducting, the electric current C that flows through ₄, C ₅, L ₃, L ₄, BG ₁, R ₃, make BG ₂End, realize starting of oscillation, C ₄, C ₅The charging energy storage, behind the certain hour, electric current is tending towards reducing, at L excessively ₄, L ₃The last induction BG that sends as an envoy to ₂Conducting, BG ₁The electromotive force that ends makes BG ₂Conducting BG ₁End, at this moment C ₄, C ₅Discharge, electric current is through BG ₂, R ₆, L ₄, L ₃Finish, thereby finish series resonance one time, because series voltage is very high, again because of C ₅＜＜C ₄So, C ₅The voltage of last distribution is very high, and this voltage is added in the two ends of fluorescent tube, is enough to make the breakdown build-up of luminance of gas in the fluorescent tube, suitably adjusts the fluorescent tube parameter, makes the fluorescent tube internal resistance very big, behind lamp lighting-up, to C ₅Influence is little, makes circuit keep the series resonance state, makes fluorescent tube continue conducting.
