Working Principle of Christmas LED String Light


    China-base Remind You:

    The single LED beads produced can only work at low voltage (about 3V) and low current (about several milliamperes), and emit very weak light.

    Many LED beads need to be connected in series or in parallel; at the same time, single LED beads are single-guide electric. In order to make full use of the positive and negative half-cycle current of AC, an integrated circuit chip is needed to convert 220V AC power supply into DC power matching the voltage and current energy of the LED set to meet the requirements of the LED bead assembly and enable it to glow normally.
