More Information
Summary:The utility model discloses an LED dimming circuit and an LED dimming system. The LED light modulation circuit comprises a light modulation module, wherein a first end of the light modulation module is connected with a first AC input end; the diode is located between the second end of the dimming module and a second alternating-current input end, the cathode of the diode is connected with the second end of the dimming module, and the anode of the diode is connected with the second alternating-current input end; wherein the dimming module receives a dimming control signal and obtains dimming data from the dimming control signal so as to superpose the dimming data on an alternating-current voltage to generate a carrier signal, and the diode performs half-wave rectification on the alternating-current voltage and provides an internal power supply voltage for the dimming module. According to the LED dimming circuit, a diode is additionally arranged between the power supply module and the second alternating current
