RGB synchronous intelligent light string

The invention discloses an RGB synchronous intelligent light string. The RGB synchronous intelligent light string comprises an intelligent power supply, a controller, light strings and a main circuit,wherein the plurality of light strings are connected in parallel with the main circuit; the intelligent power supply is connected with the controller; the controller is connected with the main circuit; a 220 V voltage is accessed into one end of an IP44 plug; the other end of the plug is accessed into a resistance wire for current protection, a piezoresistor for voltage limiting control, a filterfor noise filtration and signal separation and a filtering circuit for high-frequency resistance and low-frequency passing; an output end of the filtering circuit is connected to an input end of an MOSFET and a DCDC transformer; the DCDC transformer outputs direct current of which the voltage is changed into a driver and an IRF; the IRF is connected with a program module, a remote control module,a WiFi module and a Bluetooth module; a signal output by the IRF passes through a driving module; the driving module and an output end of the DCDC transformer are connected to the input end of the MOSFET; and an output end of the MOSFET is connected to an end part of the main circuit. The RGB synchronous intelligent light string can simultaneously control the colors of the plurality of light strings to improve a decorative effect.
