Description

Integrate new type fluoresent lamp starting module

The utility model relates to a kind of circuit arrangement of discharge lamp igniting, particularly a kind of integrated novel fluorescent start module.

At present, the ballasting circuit that is used for fluorescent lamp ignition trigger, work mainly contains inductance type circuit and capacitance voltage-multiplying type circuit.Inductance type ballast starts fluorescent tube also must have starter, toggle speed is slower, starting current is big, easily tube filament is blown, and shortens fluorescent tube useful life, under voltage instability and the higher situation of voltage, ballast is easy to generate and exchanges cry, and the power consumption of ballast own is big, and the life-span is short, poor reliability, serious interference.Capacitance voltage-multiplying type start-up circuit of the prior art though can directly start fluorescent tube quickly, just often also can start for the fluorescent tube of filament breaking gas in pipe, the work noiseless, but its circuit function is poor, and power output does not reach requirement, still is difficult to promote the use of.

The purpose of this utility model is for overcoming above-mentioned weak point, and provides a kind of power output big, but low-voltage, negative temperature start, the work noiseless, disturb little, reliable operation, the integrated novel fluorescent start module of good energy-conserving effect.

Integrated novel fluorescent start module of the present utility model comprises ballast resistance and the voltage doubling rectifing circuit in the output loop, it is characterized in that it also has polarity free capacitor accumulator, final stage filter circuit, input, output safety relief resistance, voltage doubling rectifing circuit is four multiplication of voltage full-wave rectifying circuits.

Fig. 2 is the utility model circuit diagram;

Fig. 3 is a printed circuit board.

Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.

Four multiplication of voltage full-wave rectifying circuits comprise crystal diode D ₁～D ₆, capacitor C ₁～C ₆, D ₁Anodal, D ₂Negative pole, D ₃Positive pole and C ₃One end also meets D ₃Negative pole, D ₄Positive pole and C ₄, C ₅An end and meet D ₄Negative pole, D ₅Negative pole, D ₆Positive pole and C ₆One end also meets C ₃, C ₄, C ₅, C ₆The other end and input safety relief resistance R ₁One end is connected to input B, R ₁The other end, D ₁Negative pole, D ₅Positive pole and C ₁, C ₂An end be connected to input A, C ₁The other end, output safety relief resistance R ₂One end, D ₆Negative pole and ballast resistance R ₄One end also meets R ₄The other end is output C, R ₂The other end, D ₂Anodal, C ₂The other end and ballast resistance R ₃One end also meets R ₃The other end is output D, C ₃, C ₄, C ₅, C ₆Form the polarity free capacitor accumulator simultaneously, C ₁, C ₂Form the final stage filter circuit.Each electronic component by welding shown in Figure 3 good after, use the epoxy encapsulation moulding, hold by A, B and draw power input line, hold by C, D and draw the output connecting line that connects the fluorescent tube two ends respectively.

The utility model is owing to adopt above design, and power output can be by choosing C ₃～C ₆Parameter regulation can start in input voltage 140V～250V scope smoothly, low temperature-10 ℃ energy operate as normal, relatively existing pure capacitive reactance formula ballasting circuit saves energy 25～30%, the work noiseless, disturb little, reliable operation, economical and practical.
