Beschreibung
Zusammenfassung:	The utility model discloses an AC power supply voltage adjusting device, comprising a first current-limiting and voltage-dropping resistor, one end of which is connected with an AC power supply phase line L; the second current-limiting and voltage-dropping resistor is connected with the other end of the first current-limiting and voltage-dropping resistor; the alternating current input end of the single-phase rectifier bridge is connected in parallel with the second current-limiting and voltage-dropping resistor; the cathode of the voltage stabilizing diode is connected with the anode of the direct current output end of the single-phase rectifier bridge, and the anode of the voltage stabilizing diode is connected with the cathode of the direct current output end of the single-phase rectifier bridge; one end of the third current-limiting and voltage-dropping resistor is connected with the positive electrode of the direct-current output end of the single-phase rectifier bridge; and a light-emitting diode anode
