Patent ID: 11719395

Abstract:
Disclosed is a white and warm white LED synchronous intelligent light string assembly, which includes a white LED chip and a warm white LED chip arranged inside the light bead, and the control IC can control different flashing modes of the LED chips after receiving commands. One end of the IP44 plug is connected to a 24-230V power supply, and the other end of the plug is connected to a fuse for current limitation, a varistor for voltage control, a filter for filtering out noise and separating signals, and a filter circuit for passing the low frequencies and attenuating the high frequencies. Outputs of the filter circuit are respectively connected to an input of the MOSFET and a DCDC transformer. The DCDC transformer outputs a direct current with an altered voltage to a driver and an IRF. The IRF is connected with a program module, a remote-control module and a WiFi & Bluetooth module, and the signal output by the IRF passes through the driving module, both of outputs of the driving module and the DCDC transformer are connected to an input of MOSFET while an output of MOSFET is connected to one end of the main wire. The present disclosure achieves simultaneous control of a plurality of light strings.
