US 2026/0283033 A1 · LED LIGHTING STRIP

Abstract

A light-emitting diode (LED) lighting strip includes conductive lines and LED modules. The LED module includes LED lighting beads electrically connected with the conductive lines and arranged orderly on the conductive lines to form a strip. One of the conductive lines is a communication conductive line, and the remaining three are power-supplying conductive lines. On the communication conductive line, the LED lighting beads are connected in series. On the power-supplying conductive lines, the LED modules are connected in parallel, and the LED lighting beads of each LED module are connected in series. The LED lighting strip adopts an arrangement of serial-parallel connection for power and serial connection for signal to achieve various application solutions for different power supply voltages, and as a consequence, a serial communication protocol is adopted to control each of the LED lighting beads of the LED lighting strip, in order to realize diversification of lighting effect.
