US Patent 10907786 RGB synchronous intelligent light string

A RGB synchronous intelligent light string assembly comprises, electrically connected, an intelligent power supply including an IP44 plug and a controller, a main wire and light strings connected in parallel thereto, wherein one end of an IP44 plug is connected to a 220 V power supply and the other end connected to a fuse, a varistor, a filter, and a filtering circuit; the filtering circuit is connected to a MOSFET and a DC-DC transformer outputting a direct current with an altered voltage to a driving module and a FET; the FET is connected with a program module, a remote-control module, a WiFi & Bluetooth module; a signal output by the FET passes through a driving module; the driving module and the DC-DC transformer are connected to a main wire end through the MOSFET. The assembly simultaneously controls colors of the light strings to promote decorative effect.
