Diagram of how to connect a cable at each end of a led lamp strip
First, install the current-limiting resistor on the negative pole of the power cord. Then separate the positive and negative lines of the LED lamp strip. Use a stripper to remove the positive wire of the LED lamp belt. Stripped positive line of LED lamp. This is shown in the following figure. Connect the negative wire of the power supply with the positive wire of the LED lamp strip.
The LED lamp belt is equipped with a special plug, which is connected with the wires on both sides of the lamp belt in the way of a pin. Because the LED itself is a diode and is driven by direct current, it has positive and negative poles. If the positive and negative poles are connected in reverse, they are insulated and the lamp belt is not bright. You need to flip the plug into it.
How to connect the led lamp strip? we can use this method of wiring at both ends, which is to short connect the two pins on both sides of the lamp holder of the LED. Then connect the internal power supply.
How to connect the two ends of the led lamp tube there are two wires at both ends of the LED lamp tube. When connecting, we should first distinguish the positive and negative poles of the wires, then connect the positive wires and the positive extremes of the power adapter, and connect the negative wires and the negative extremes of the power adapter.
LED lights generally use 220V voltage, the connection method is as follows: the internal contact switch of the lamp port leads to the hot wire, the side contact zero wire, so the safety factor will be improved. Draw the hot wire of the lamp mouth out of one end of the wire connection switch and the hot wire at the other end of the switch. Fix the lamp port, install LED, etc.
First connect the diode to the positive pole of the power supply. After connecting the diode u, separate the two wires connected to the LED lamp by hand. After separating the wire of the LED lamp, use a peeler to remove the wire skin from the negative pole of the lamp. Connect the negative wire of the stripped LED lamp to the negative wire of the power supply.

1. First install the current-limiting resistor on the negative pole of the power cord. Then separate the positive and negative lines of the LED lamp strip. Use a stripper to remove the positive wire of the LED lamp belt. Stripped positive line of LED lamp. This is shown in the following figure. Connect the negative wire of the power supply with the positive wire of the LED lamp strip.
2. How to connect the led lamp into the wire at both ends: this is one of the more common connection methods in the early days. Because of the advantages of convenient wiring and other advantages, there are still some LED lamp manufacturers. Connect the two needles of the lamp holder short, and then connect them to the internal constant current power supply. This connection method can work normally as long as the traditional starter is removed.
3. The connection method of led lamp is as follows: tool / raw material: LED lamp. First of all, the length is determined and intercepted by integers. Random shortening will cause a unit not to shine. If you need a length of 5m, the lamp belt needs to be cut by 8m. If the positive and negative electrodes are connected in an insulated state, the lamp belt is not bright.
4. Prepare a screwdriver and power cord. The wiring step of the LED lamp: first turn off the power supply, there will be a ballast with inductance inside the lamp rack, remove the ballast, and then unplug the starter. Connect the zero line and the hot wire to both ends of the lamp rack respectively. Put the lamp tube in the lamp rack, turn the lamp tube, and it will glow with electricity.
How to connect the LED light strip? I think there are three wires in it.
1. The LED lamp is connected with three wires, one is a positive line, one is a negative line, and the other is a controller. The connection is as follows: no matter how many switches control several lights, the switch is the on-off of the controlled fire line, so the lamp is directly connected to the zero line, and then the fire line and the control line go into the switch.
2. After purchasing the LED light belt, there will be an installation instruction book with installation illustration. Just follow the instructions to illustrate the connection line.
3. First, connect the current limiting resistor to the positive wire of the power supply. Then separate the lines connected to the LED lamp. Use a peeler to remove a short section of the negative skin of the lamp. After removing the wire skin, the negative electrode line of LED lamp tube. Then connect the positive pole of the power lamp with the peeled LED negative electrode.
4. Most of the LED light strips on the market are 2 lines, and there are also three lines of light strips, which are tricolor light source bars, which can be changed into light. The lamp strip power supply is 220V through the LED drive power supply constant current transformer output to the LED lamp strip. The output voltage is generally 12v, 24v-80V and so on.
