Lighting device control system

A lighting device control system, comprising a host side and at least one device side, wherein

• the host side comprises a power transformer, a power supply encoding circuit, a signal receiving module, and a microcontroller unit (MCU);
• an output terminal of the power transformer is connected to a voltage input terminal of the power supply encoding circuit, a signal output terminal of the signal receiving module is connected to a signal input terminal of the MCU, and a signal output terminal of the MCU is connected to a signal input terminal of the power supply encoding circuit;
• the device side comprises a decoding circuit, a drive circuit, and light emitting diode (LED) lamp beads;
• and
• a first voltage output terminal of the power supply encoding circuit is separately connected to a signal input terminal of the decoding circuit and a voltage input terminal of the drive circuit via a dual-wire power line, a signal output terminal of the decoding circuit is connected to a signal input terminal of the drive circuit, and an output terminal of the drive circuit is connected to the LED lamp beads.
