The output end of the modulation decoder is connected in parallel with a plurality of LED driving sub-units, each LED driving sub-unit comprises a driving sub-chip, the input end of each driving sub-chip is connected with a plurality of color sub-lines, each color sub-line is provided with a sub-LED lamp string and a first resistor, and the other end of each color sub-line is connected with an anode outgoing line of the modulation decoder; and the grounding end of the LED driving sub-unit is connected with the negative electrode outgoing line of the modulation decoder.

Description

technical field [0001] The invention relates to a light-emitting diode driving system for an LED light strip, and belongs to the technical field of light-emitting diodes. Background technique [0002] The existing RGB-LED light strip refers to the assembly of LED lamp beads and chip resistors on a strip-shaped FPC (flexible circuit board) or PCB hard board. The RGB circuit board is covered with high-quality PI layers on both sides, and half a meter is connected to one meter. Or one meter is a body, weld four parallel wires at the front end and connect them to the four core wires covered with rubber, and then perform secondary rubber wrapping and other processes, and add an external RGB dedicated controller power supply to output a positive pole of the power supply and three wires. RGB negative line, RGB light color conversion lighting, RGB-LED light strips are suitable for LED lighting design solutions such as building decoration and stage lighting systems. However, the exi...
