1. Resistor-capacitance: The scheme is simple, the device is small, the cost is low, and the constant current is not constant.

2. Non-isolated power supply: moderate cost, IC constant current, but there is also the danger of leakage caused by breakdown of the light board. Therefore, it is also required that the structural shell of the lamp body must insulate the panel light.

3. Isolated power supply: high cost, IC constant current, good security.
