Some customers design the lamp board first, then look for the power supply and find it difficult to have a suitable power supply, or the current is too large, the voltage is too small (such as I> 350mA, V <40V); or the current is too small, the voltage is too high (such as I180V) The result is serious heat, low efficiency, or insufficient input voltage range. Choosing a suitable string and parallel connection method is the same as the voltage and current applied to each LED lamp bead, and the power supply's effect can exert its excellent performance. The most appropriate method is to communicate with the power supply manufacturer and tailor it.
