The first, second, and third light-emitting diodes (respectively, red, green, and blue as a group) are used in parallel. The negative pole of each light-emitting pole has a line width, plus a corresponding resistance must be passed. Only the negative power line, three lines and three resistors can be connected, and there must be a gap between the line and the line and the components, which takes up too much space in the slender light-emitting unit, which is missing. In other words, if you want to set a group of light-emitting diode modules, you need to pull out at least four wires; Similarly, if you want to set ten groups, you must have at least forty wires.
