DC control modules require external 0-10V dimming or color-tuning modules and dedicated dimming cables, resulting in a large number of wires, poor reliability and weather resistance of the dimming modules, and high operation and maintenance costs. Extensive wiring leads to high construction difficulty and workload.

[0004] 2. Limited control: It is difficult to achieve integrated multi-device linkage and intelligent control of LED lighting dimming, AC sockets, and AC appliances with different voltage forms. The core measurement and control system is costly, difficult to program, and has low reliability.

[0005] 3. Weak remote IoT interaction capabilities: Reconstructing the IoT requires the integration of many auxiliary modules, making it impossible to perceive and monitor the health status of the load online, and difficult to remotely program and upgrade;

[0006] 4. Safety hazards: Ordinary relay operation generates electric arcs, has a short lifespan, poor safety, and lacks a load health warning mechanism. Utility Model Content
