How can an LED fluorescent lamp power supply match a lamp?

The voltage is too small (such as I>350mA, V<40V); either the current is too small or the voltage is too high (such as I180V), resulting in severe heat generation, low efficiency, or insufficient input voltage range. Choose a suitable series and parallel connection method, the voltage and current applied to each LED lamp bead are the same.
