And comprising an AC power source 210, a first group of LEDs 220 and a second group of LEDs 230' and the forward voltage of the first group of LEDs 22 and the second group of LEDs 230 It is 9 volts. When the output AC voltage of the AC power source 210 is equal to or greater than 90 volts, the lighting of the first group of LEDs is started. When the output AC voltage continues to rise and then falls back to 9 volts, the first f-emitting diode 220 is turned off. Similarly, when the output AC voltage is equal to or less than -90 volts, the second group of light-emitting diodes 230 is started to be turned on. When the output AC voltage continues to drop and rises again to _9 volts, the second group of LEDs 23 is turned off. Referring to FIG. 2, a current waveform diagram of the alternating current light emitting diode of FIG. 1 is shown, wherein the horizontal axis is time, which is displayed by voltage phase, and the vertical axis is current unit is mA (milliampere) < As shown in FIG. 2, when the phase is about 3 〇, the voltage starts to be greater than 90 V, and the first group of LEDs 22 illuminates. At a phase of about 90 degrees, the voltage reaches a maximum value and the current flowing through the first group of light-emitting diodes 220 is about 5.2 mA. When the phase is 15 〜 to 21 ,, the voltage is less than 90 V and greater than -90 V. At this time, the first group of LEDs 220 and the first group of LEDs 230 are turned off, so the current is 〇mA. At a phase of about 2 i ,, the voltage begins to be less than -9 〇 V, and the second set of light emitting diodes 230 is illuminated. At a phase of approximately 270 degrees, the voltage reaches a minimum and the current flowing through the second set of 201212701 LEDs 230 is approximately _5.2 mA. When the phase is 330 degrees to 360 degrees, the voltage is less than 90 V and greater than _9 〇 V. At this time, the first group of LEDs 220 and the second group of LEDs 23 are turned off, so the current is 〇 mA. As can be seen from FIG. 2, the first group of LEDs 220 and the second group of LEDs 230 are sometimes turned on and sometimes turned off, which may cause flickering, which may cause discomfort to the human eye. The prior art is not suitable for use in lighting facilities. Figure 3 is a schematic illustration of another conventional AC light emitting diode used. As shown in FIG. 3, it is composed of an AC power source 21A, a group of LEDs 22A, and a full bridge rectifier 250. The working principle is that the AC mains is passed through the full-bridge rectifier 250, and the positive and negative AC chords are rectified into a waveform having only a positive half-cycle. The waveform is directly used to directly drive the LEDs 22A. However, such a waveform causes a problem that the LED 220 is flickering and the utilization is low. Wherein, when the input voltage is low, the input voltage is lower than the on-voltage of the light-emitting diode 220, so that the light-emitting diode 22 is turned off. When the input voltage is high, the input voltage is greater than the turn-on voltage of the light-emitting diode 220, and the light-emitting diode is in a bright state. In general, the light-emitting diode 220 is extinguished with the input voltage, which results in a low utilization rate of the light-emitting diode and is prone to flicker. Therefore, there is still room for improvement in the conventional light-emitting diode lighting device.

One end of the second resistor R2 is electrically connected to the first output end 521, and one end of the second resistor R3 is electrically connected to the second resistor R2, and the other end of the second resistor R3 is electrically connected to the second output end 522. One end of the fourth resistor R4 is electrically connected to the first output end 521, and one end of the fifth resistor R5 is electrically connected to the fourth resistor R4, and the other end thereof is electrically connected to the second output end 522. The MOSFET is 〇s1; and the gate is connected to the gate of the second switch Q2 and the gate of the second N-type MOS field effect transistor NMOS2, and is controlled by a voltage The VB is controlled to be turned on or off by the second switch Q2, the source thereof is connected to the second output terminal 522, and the gate thereof is connected to the connection end of the fourth resistor R4 and the fifth resistor R5. The S-second second N-type MOSFET field-effect transistor NM〇S2 has its drain connected to the s-up resistor Rib, its source is connected to the second output terminal 522, and its gate is connected to the second resistor R2 and the gate The connection end of the third resistor R3. Wherein, when the second N-type MOS field effect transistor is turned on, the voltage across the first resistor R1 is sufficient to turn on the first switch Q1, and when the second N-type gold oxide When the semiconductor field effect transistor is not turned on, the voltage across the first resistor R1 is insufficient, and the first switch q is turned off. The control circuit 540 causes the second switch Q2 and the second N-type MOSFET to act as a voltage between the first and second reference voltages when the voltage Vo of the first output 521 of the rectifier circuit 520 is between the first and second reference voltages The nm 〇 S2 is turned on, and the first switch Q 1 is turned on, which causes the second illuminating diode module 12 201212701 D4 and the first illuminating diode module D6 to be in a parallel state. Otherwise, the second switch Q2 and the second n-type MOS field effect transistor NMOS2 are not turned on, which may cause the first switch to be non-conductive. Wherein the first reference voltage is greater than the second reference voltage, the first reference voltage is determined by the resistance values of the second and third resistors R2, R3, and the second switch Q2 and the second n-type MOSFET The threshold voltage of the transistor NMOS2 is determined by the resistance values of the fourth and fifth resistors R4 and R5 and the threshold voltage of the first N-type MOSFET/NMOS1. The operation principle of the driving control device 450 is as follows: When the chopping AC voltage Vac, filtered is less than the 1/2 voltage peak of the filtered AC voltage Vac, fntered, the rectifying circuit 52 is in a non-conducting state when the filtering The AC voltage Vac, fntered is greater than the filtered AC voltage Vac, and the rectifier circuit 52 is turned on when the voltage is 1/2. • When the filtered AC voltage Vac, filtered from 〇 to the filtered AC voltage Vac, filtered 1/2 voltage peak, the first diode di and the second diode D2 are turned on, the third diode The body D3 is turned off, and the first capacitor C1 and the second capacitor C2 are in parallel to release energy to the LED light-emitting circuit 420. The voltage Vo of the first output terminal 521 of the rectifier circuit 52 is replaced by the first capacitor. C1 and the second capacitor C2 are clamped at a peak voltage of 1/2 of the filtered AC voltage Vac, fiitered. 13 201212701 At this time, the control circuit 540 controls the first switch Q1 and the second switch Q2 to be turned on, and the second LED D5 is mounted. The second LED module and the first LED module are D6 is in parallel. Since the filtered AC voltage Vac is less than the filtered AC voltage Vac and the 1/2 voltage peak of the fiitered, the second LED module D4 and the first LED module 〇6 are connected in parallel. The state is used to reduce the forward conduction voltage of the second LED module D4 and the first LED module D6, thereby improving the utilization ratio of the overall LED module at this time. When the filtered AC voltage V ac, fi 11 ered is between the ripple AC voltage Vac, the filtered 1/2 voltage peak and the filtered AC voltage Vac, the filtered voltage peak, the first diode D is the second diode The body D2 and the third diode D3 are turned off, the first capacitor C1 and the second capacitor C2 stop discharging, and the voltage Vo of the first output terminal 520 of the rectifier circuit 520 changes with the filtered AC voltage Vac . At this time, the control circuit 540 controls the first switch Q1 and the second switch Q2 to be turned off. The diode D5 is turned on, and the second LED module D4 and the first LED module D6 are In-line state. When the sinusoidal parent voltage V ac , fi丨tered is the chopping AC voltage Vac, the voltage peak of the filtered, the first diode D1 and the second diode D2 are cut off, and the third diode 〇 3 is turned on, the first capacitor C1 and the second capacitor C2 are in series and charged by the filtered AC voltage, and the voltage Vo of the first output terminal 521 of the 201212701 stream circuit 520 varies with the filtered AC voltage Vac. At this time, the control circuit 540 controls the first switch Q1 and the second switch Q2 to be turned off. The diode D5 is turned on, and the second LED module D4 and the first LED module D6 are In-line state. Since the filtered AC voltage Vac at this time is equal to the voltage peak of the filtered AC voltage Vac, fiitered, the second LED module D4 and the first LED module D6 are in series, which is compared. A high forward voltage is applied to prevent the second LED module D4 and the first LED module D6 from being burned because the voltage Vo of the first output terminal 521 is too high. Fig. 7 is a schematic diagram showing the voltage Vo and current of the first output terminal 52 1 of the present invention. It can be seen from FIG. 7 that at the circle a and the circle B, since the first capacitor C1 and the second capacitor C2 are discharged, the level and current level of the voltage Vo of the first output terminal 521 can be maintained at a certain value. The second illuminating φ diode module D4 and the first illuminating diode module D6 are turned on to generate a light source. On the other hand, the conventional technique often causes the light-emitting diode to be turned on due to the current approaching the ampere or the voltage is too low, and the light-emitting diode is caused to flicker. Fig. 8 is a schematic view showing another embodiment of a light-emitting diode lighting device of the present invention, which is a lamp. Fig. 9 is a schematic view showing still another embodiment of a light-emitting diode lighting device of the present invention, which is a ceiling-mounted lamp. 15 201212701 In summary, the LED driving system of the present invention utilizes the characteristics of the capacitor and the diode to maintain the on-voltage of the light-emitting diode by the parallel connection of the capacitor to the light-emitting diode when the input voltage is low. It is also equipped with various LED driving circuits at the rear to improve the utilization of the overall LED. In addition, the flashing frequency of the light-emitting diode is increased at the same time, making it impossible for the human eye to detect. When the input AC voltage is low, the first switch Q1 and the second switch Q2 are turned on by the control signal, and the second LED module and the first LED module D6 are turned on in parallel. The first capacitor c 1 and the second capacitor C2 are connected in parallel to the second LED module D4 and the first LED module D6 to be electrically connected. When the input AC voltage is high, the first switch Q1 and the second switch are turned off by the control signal. At this time, the second LED module D4 and the first LED module D6 are The series is turned on, and the second light emitting diode module D4 and the first light emitting diode module D6 are powered by the input power source to be turned on, thereby improving the utilization ratio of the light emitting diode and increasing the blinking frequency thereof. To the extent that the human eye is not easily detectable, the second LED module D4 and the first LED module D6 are both in a conducting state, thereby also reducing the light source flicker to the human eye. The effect of the present invention is to improve the utilization of the light-emitting diode in the conventional light-emitting diode lighting device and to cause flickering. As can be seen from the above, the present invention displays both in terms of purpose, means and efficacy. It is very different from the characteristics of the prior art, and it is of great practical value.
