The selection of outsourcing drive power mainly depends on the constant current and the voltage scale of the constant current. The constant current value is selected as the LED\\\'s standard current is lower.

If the fluctuation amplitude of the output current is too large, it will cause flicker. The higher the current, the higher the brightness, and the lower the current, the lower the brightness.

LEDs are driven by DC, so a power adapter, ie LED drive power, needs to be added between the mains and the LED. Its function is to convert AC mains power into DC power suitable
