During people constantly carry out the discussion of electric ballast driving LED illumination, for example utility model patent 201220182562.9 discloses electric ballast driving LED modular converter.This module is utilized the electric energy driving LED obtained after the direct current limliting rectifying and wave-filtering of the high-frequency and high-voltage power supply voltage stabilizing of electric ballast output.Because not being directly controls electric ballast output, be to utilize resistance and current limit by inductance and triode voltage stabilizing pattern, power output and energy-saving effect have much room for improvement.AC AC power that also can't compatible single-ended input.
Because LED must be used DC power supply, driven, therefore every money light fixture all will be equipped with the galvanic driving power of a energy output.These power supplys are all to use the alternating current conversion to obtain, and exist larger current ripples after conversion, and when current ripples is above over 5%, the LED lamp just there will be by the observable flicker of camera.
Early stage fluorescent tube, be furnished with coil ballast and neon bulb starter, utilizes the heating power conducting of neon bulb starter and disconnection process to make the coil ballast produce high voltage pulse, lights fluorescent tube.Because energy consumption is high and the development of electronic technology, the coil ballast is progressively replaced by electric ballast.
The traditional type fluorescent tube has been installed and used in huge numbers of families, and it all has been equipped with the fixed support that coil ballast or electric ballast are housed.Output due to electric ballast is the high-frequency high-voltage constant-current formula at present, common LED fluorescent lamp driving power supply can't adapt to the output characteristic of electric ballast, after must being removed electric ballast and the straight-through AC alternating current of repacking to original fluorescent tube fixed support, could use, the fluorescent lighting fixture after repacking can't directly be used common fluorescent tube again.Also some user has reequiped LED fluorescent lamp single-ended or the Double-End Source input simultaneously, installs and brings very big puzzlement to domestic consumer like this, can't install and use voluntarily.

Embodiment
Fig. 1 is coil ballast wiring schematic diagram
When the AC AC power, through Inductive ballast, the AC power of low frequency can't effectively be passed through C1, and the electric capacity of C2 and C3 arrives the neon bulb starter, and the neon bulb starter is not worked.The AC AC power directly arrives rectifier diode D1 through Inductive ballast, D2, and D3, D4, D5, D6, D7, D8 is rectified into direct current, by capacitor C 5, carries out filtering.Make C5 obtain a galvanic current source, then power and use to LED by power-switching circuit.
Figure 2 shows that the electric ballast wiring schematic diagram, electric ballast oscillatory feedback signal will be by two ends conducting ability oscillatory work the power output of fluorescent tube.Shown in Fig. 5, electric ballast oscillatory feedback signal Zheng Ban Week gets back to electric ballast by C1 → D10 → Q1 → D11 → C2.Electric ballast oscillatory feedback signal Fu Ban Week gets back to electric ballast by C2 → D12 → Q1 → D9 → C1.Input 11 and the complete conducting of 12 electric ballast feedback signal.The input 13 of electric ballast and 14 electronic feedback signal Zheng Ban Week and Fu Ban Week signal are by the conducting of C3 coupling capacitance.After input 11 and 12 oscillatory feedback signals and input 13 and 14 oscillatory feedback signal conductions, electric ballast work, the high frequency electric source of output can pass through D1, D2, D3, D4, D5, D6, D7, the rectification of D8 and the filter capacitor of C5 obtain the required direct current energy of power-switching circuit.When the direct voltage obtained during higher than set point, by R3, R4, R5, ZD2, ZD3, the voltage detecting circuit that C4 forms makes Q2 conducting → Q1 cut-off → electric ballast input 11 and 12 cut off → electric ballasts of oscillatory feedback signal stop exporting.When the direct voltage the obtained direct current energy required lower than power-switching circuit, by R3, R4, R5, ZD2, ZD3, the voltage detecting circuit that C4 forms makes Q2 cut-off → Q1 conducting → electric ballast input 11 and 12 oscillatory feedback signal conduction → electric ballast work output, thereby make C5 obtain one, meets the DC power supply that the power supply conversion requires.Power and use to LED by power-switching circuit again.
