如圖2所示，其高頻電源為正半周時之動作原理為：自圖2可知，當電子式安定器100的第一交流輸入端AC1與第二交流輸入端AC2接有交流電源時，電子式安定器100的第一輸出端T1與第二輸出端T2供電於發光二極體燈管200管外的第一連接端11與第二連接端12，第三輸出端T3與第四輸出端T4供電於發光二極體燈管200管外的第三連接端13與第四連接端14，此時當第一高頻電感器21的一端A與第二高頻電感器22的一端C的高頻電源為正電時，其高頻電源從第一輸出端T1到第一高頻電感器21的一端A，經過第一半波二極體71的陽極端到第一半波二極體71的陰極端，第一濾波電容器81的正電端與發光二極體電路90的正電端E，再經過發光二極體電路90的發光二極體，再到發光二極體電路90的負電端F與第一濾波電容器81的負電端，再到第二半波二極體72的陽極端與陰極端，再回到第一高頻電感器21的另一端B與第二輸出端T2，而完成半周期的供電；同時第二高頻電感器22的一端C的高頻電源為正電時，其高頻電源從第三輸出端T3到第四高頻電感器22的一端C，不能經過第三半波二極體73的陰極端，因此不能供電於第二濾波電容器82的負電端與發光二極體電路90的負電端F，由此可知第二高頻電感器22的一端C在高頻電源為正電時，不能供電於發光二極體電路90，只有高頻電源在第一高頻電感器21的一端A為正電時才能供電於發光二極體電路90；由上述可知，在高頻電源為正 半周時，只有一個正半周的電壓供電於發光二極體電路90。 As shown in FIG. 2, the principle of operation when the high-frequency power source is in the positive half cycle is as follows: As shown in FIG. 2, when the first AC input terminal AC1 of the electronic ballast 100 and the second AC input terminal AC2 are connected to the AC power source, The first output end T1 and the second output end T2 of the electronic ballast 100 are powered by the first connection end 11 and the second connection end 12 outside the tube of the LED tube 200, and the third output end T3 and the fourth output end The terminal T4 is powered by the third connection end 13 and the fourth connection end 14 outside the LED tube 200. At this time, one end A of the first high frequency inductor 21 and one end C of the second high frequency inductor 22 When the high frequency power source is positively charged, the high frequency power source passes from the first output terminal T1 to the one end A of the first high frequency inductor 21, passes through the anode end of the first half wave diode 71 to the first half wave diode The cathode end of the body 71, the positive terminal of the first filter capacitor 81 and the positive terminal E of the LED circuit 90, and then the LED of the LED circuit 90, and then to the LED circuit 90 The negative terminal F and the negative terminal of the first filter capacitor 81, and then to the anode terminal and the cathode terminal of the second half-wave diode 72, return to the first high The other end B of the inductor 21 and the second output terminal T2 complete the power supply of the half cycle; while the high frequency power supply of the one end C of the second high frequency inductor 22 is positive, the high frequency power supply is from the third output end. T3 to one end C of the fourth high frequency inductor 22 cannot pass through the cathode end of the third half-wave diode 73, and therefore cannot be supplied to the negative terminal of the second smoothing capacitor 82 and the negative terminal F of the LED circuit 90. Therefore, it can be seen that the one end C of the second high frequency inductor 22 cannot be supplied to the light emitting diode circuit 90 when the high frequency power source is positive, and only the high frequency power source is positive at one end A of the first high frequency inductor 21. Power can be supplied to the LED circuit 90; it can be seen from the above that the high frequency power supply is positive At half cycle, only one positive half cycle voltage is supplied to the light emitting diode circuit 90.
如圖2所示，其高頻電源為負半周時之動作原理為：自圖2可知，當電子式安定器100的第一交流輸入端AC1與第二交流輸入端AC2接有交流電源時，電子式安定器100的第一輸出端T1與第二輸出端T2供電於發光二極體燈管200管外的第一連接端11與第二連接端12，第三輸出端T3與第四輸出端T4供電於發光二極體燈管200管外的第三連接端13與第四連接端14，此時當第一高頻電感器21的另一端B與第二高頻電感器22的另一端D在高頻電源為正電時，其高頻電源從第二輸出端T2到第一高頻電感器21的另一端B，不能經過第二半波二極體72的陰極端，因此不能供電於第一濾波電容器81的負電端與發光二極體電路90的負電端F，由此可知第一高頻電感器21的另一端B在高頻電源為正電時，不能供電於發光二極體電路90，只有高頻電源在第一高頻電感器21的一端A為正電時，才有供電於發光二極體電路90；同時第二高頻電感器22的另一端D在高頻電源為正電時，其高頻電源從第四輸出端T4到第二高頻電感器22的另一端D經過第四半波二極體74的陽極端到陰極端，經過第二濾波電容器82的正電端與發光二極體電路90的正電端E，再經過發光二極體電路90的發光二極體，再到發光二極體電路90的負電端F與第三濾波電容器82的負電端，再到第三半波二極體73的陽極端與陰極端，再回到第二高頻電感器22的一端C與第三輸出端T3，而完成半周期的供電，由此可知第三高頻電感器21的另一端B在高頻電源為正電時，不能供電於發光二極體電路 90，只有高頻電源在第二高頻電感器22的另一端D為正電時才有供電於發光二極體電路90；由上述可知，在高頻電源為負半周時，只有一個正半周的電壓供電於發光二極體電路90。 As shown in FIG. 2, the operation principle of the high frequency power supply is negative half cycle: as shown in FIG. 2, when the first AC input terminal AC1 of the electronic ballast 100 and the second AC input terminal AC2 are connected with AC power, The first output end T1 and the second output end T2 of the electronic ballast 100 are powered by the first connection end 11 and the second connection end 12 outside the tube of the LED tube 200, and the third output end T3 and the fourth output end The terminal T4 is powered by the third connection end 13 and the fourth connection end 14 outside the LED tube 200. At this time, when the other end B of the first high frequency inductor 21 and the second high frequency inductor 22 are When the high frequency power source is positive at one end D, the high frequency power source from the second output terminal T2 to the other end B of the first high frequency inductor 21 cannot pass through the cathode end of the second half wave diode 72, and thus cannot The power supply is supplied to the negative terminal of the first filter capacitor 81 and the negative terminal F of the LED circuit 90. It can be seen that the other end B of the first high frequency inductor 21 cannot be powered by the light when the high frequency power source is positive. In the polar body circuit 90, only when the high frequency power source is positive at the end A of the first high frequency inductor 21, the power supply is applied to the light emitting diode 2 The body circuit 90; at the same time, the other end D of the second high frequency inductor 22 is positively charged, and the high frequency power source passes from the fourth output terminal T4 to the other end D of the second high frequency inductor 22 through the fourth The anode end to the cathode end of the half-wave diode 74 passes through the positive terminal of the second filter capacitor 82 and the positive terminal E of the LED circuit 90, and then passes through the LED of the LED circuit 90. Returning to the negative terminal F of the LED circuit 90 and the negative terminal of the third filter capacitor 82, to the anode terminal and the cathode terminal of the third half-wave diode 73, and returning to the second high-frequency inductor 22 The one end C and the third output end T3 complete the power supply of the half cycle, and it can be seen that the other end B of the third high frequency inductor 21 cannot supply power to the LED circuit when the high frequency power source is positive. 90, only the high frequency power supply is supplied to the light emitting diode circuit 90 when the other end D of the second high frequency inductor 22 is positive; as can be seen from the above, when the high frequency power supply is negative half cycle, there is only one positive half cycle. The voltage is supplied to the light emitting diode circuit 90.
綜合上述，由高頻電源為正半周與負半周之動作原理可知，在高頻電源完成正半周與負半周一周期時，本創作在發光二極體電路90之E端與F端兩端之電壓為全波整流電壓。 In summary, the principle of operation of the positive half cycle and the negative half cycle of the high frequency power supply is known. When the high frequency power supply completes the positive half cycle and the negative half cycle cycle, the present invention is at both ends of the E terminal and the F terminal of the LED circuit 90. The voltage is a full-wave rectified voltage.
