Title:
WHITE AND WARM-WHITE LED SYNCHRONOUS INTELLIGENT LAMP STRING
Document Type and Number:
WIPO Patent Application WO/2021/082436
Kind Code:
A1
Abstract:
Disclosed is a white and warm-white LED synchronous intelligent lamp string. White and warm-white LED chips are encapsulated in a lamp bead, and a control IC can control different flickering modes for the LED chips after receiving an instruction. One end of an IP44 plug accesses a voltage of 24 V-230 V, and the other end of the plug is connected to a resistance wire for current protection, a varistor for voltage limiting control, a filter for filtering out noise and separating signals, and a high-frequency-resistance and low-frequency-pass filter circuit, wherein an output end of the filter circuit is respectively connected to an input end of a MOSFET and a DCDC transformer; the DCDC transformer outputs a direct current with a changed voltage to a driver and an IRF; the IRF is connected to a program module, a remote control module, a WiFi module and a Bluetooth module; a signal outputted by the IRF passes through the driving module; an output end of the driving module and an output end of the DCDC transformer are both connected to the input end of the MOSFET; and an output end of the MOSFET is connected to an end of a main line. According to the present invention, control over multiple lamp strings can be realized at the same time.
