The invention relates to the technical field of illumination control, and discloses a phase-switching LED module three-phase power balancing device and system, and the device comprises a man-machine interaction module, a communication module, a regulation and control module, a three-phase balancing module, and a plurality of LED modules. The man-machine interaction module responds to a module power input instruction and outputs a phase switching signal to the communication module so as to output working phase and power to the communication module, the communication module receives the phase switching signal and changes high and low levels of a pin, on-off of a switching unit in the three-phase balance module is controlled through the regulation and control module, and the working phase and power of the three-phase balance module are controlled. The switching of the LED module in the three-phase input line is realized, that is, the access phase of the three-phase power supply is switched, and the power of the LED module group on the three-phase input line is averaged after the LED module group is electrified, so that the three-phase balance is realized. The technical blank of tail end load dynamic balance in an LED high-power application scene is filled, and the safety boundary and the energy utilization rate of the system are remarkably improved.
