The meaning of two-wire, three-wire, four-wire and five-wire of led strip lights

The led strip lights can be divided to four kinds according to their inner wires, which are two-wire led strip lights, three-wire led strip lights, four-wire led strip lights and five-wire led strip lights.

As for two-wire led strip lights, the two wires inside the led strip lights are the null line and power line. One of them connects with the lamp bead and the other the power source. When the socket is connected and the lights do not shed light, one just needs to turn the two pin plug upside down.

Inside the three-wire super bright led strip lights, there are three wires, and two of them are connected with the lamp bead. The wire between these two wires is for connecting the power source. The way to put electric through them is to plug the pin plug. There is no trouble to distinguish the electrode.  

The four-wire led strip lights have four wires inside, and three of them are connected to the lamp bead. One of the middle wires connects with the power source, which is called the power line, and the other middle one is the null line, therefore, when the lights are put through with power without giving out light, one just needs to turn the pin plug upside down.

As for the five-wire 5050 led strip lights, there are five wires inside the lights and four of them are connected with the lamp bead. In the middle, the left wire is the power line. So there is no trouble to distinguish the electrode for such led strip lights.
