How to connect the three wires of LED long light?
1. Most LED triplets are divided into one positive pole and two negative poles, one of which is a common pole. There is also a special, if you have a multimeter to hit the beep file, you can directly measure which is the positive pole and the negative pole. LED lamp beads will have bright light when tested correctly. Here are some pictures for you to compare with yourself.
2. 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.
3. It is very simple to connect the three wires of the LED lamp. First, we need to distinguish between the hot wire, the ground wire and the zero wire. At the interface of the LED light, we can see a telephone pole, and then we need to cut off one end of the port of the hot wire, and then connect the three wires in series to complete the connection.
4. The connection method of the three wires of the led lamp is as follows: be prepared for safety, cut the power supply, put on protective gloves, and connect the current-limiting resistance to the L-wire of the lamp.
How to connect the three wires of led lamp
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. The three wires of the led lamp are connected to the zero wire and the fire wire. Connect the zero wire and the hot wire, and one is the ground wire, the color of the ground wire is yellow and green, while the color of the hot wire is red, and the color of the zero wire is blue. The hot wire is actually equivalent to the positive pole, this line is with voltage, and the zero wire is connected by the electrical circuit, which is equivalent to the negative pole.
3. The connection of the three wires of the led lamp: be prepared for safety, cut the power supply, put on protective gloves, and connect the current-limiting resistance to the L line of the lamp. Carefully tear off the line connected to the lamp tube, then use a tool to remove a small piece of insulation from the L and N lines of the lamp, and finally connect it with the L and N lines of the lamp point to point.
4. 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.
5. First, install the current limiting resistor to the negative pole of the power cord. Then separate the positive and negative lines of the LED lamp strip. Use a peeler to remove the positive line of the LED lamp strip. The positive wire of LED lamp strip after peeling. Be careful not to remove too much skin. Then connect the negative wire of the power supply to the positive wire of the LED lamp strip.
How to connect the LED light strip? I think there are three wires in it.
The LED lamp is connected to three wires, one is a positive wire, one is a negative wire, and the other is a controller. The connection is as follows: no matter how many switches control several lights, the switch is the on and off of the controlled fire line, so the lamp is directly connected to the zero line, and then the fire line and control line go into the switch.
After purchasing the LED light belt, it will be accompanied by an installation instruction with an installation diagram. Just follow the instructions to illustrate the connection line.
First of all, 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.
I’ll buy a lamp with three wires and ask how to connect it.
1. It is very simple to connect the three wires of the LED lamp. First, we need to distinguish between the hot wire, the ground wire and the zero wire. At the interface of the LED light, we can see a telephone pole, and then we need to cut off one end of the port of the hot wire, and then connect the three wires in series to complete the connection.
2. If the lamp is three wires, it may be the metal shell that your lamp has or touches. The three wires are hot wires, which requires a switch. Zero line. The ground wire needs to be connected with the metal shell. The three-phase line needs to be connected with the city electricity by using a three-core plug.
3. The three wires of the lamp switch are the hot wire, the zero wire and the ground wire, two of which must be connected. There will be an l sign on the hot line, which needs to be connected to one of the switches. At the back of the switch, there are three contact points, l and L1, respectively. L1 and L2 should be connected by wires.
4. If there are three light wires and only two power lines, then you only need to dock the lamp line zero wire and the power supply zero wire, and the lamp wire hot wire and the power supply hot wire. Just connect the red line and the yellow-green line, distinguish according to the color, there will be no mistakes.
5. LED lamp tube with two white wires and one yellow wire. The specific wiring methods are as follows: 2 white wires are contact wire (L) and zero wire (N), and the yellow wire is grounded. Installation: LED has its own constant current source, no ballast or starter is needed. In general, the lamp tube above T8 can be installed in the lamp tube because the lamp space is large enough.
6. Red is the hot wire, blue is the zero wire, and yellow (actually yellow and green has a green wire) is the grounding wire.
LED lamp 3-wire connection!
1, LED lamp with two white lines, a yellow wire, the specific wiring methods are as follows: 2 white wires are contact wire (L) and zero wire (N), yellow wire grounding. Installation: LED has its own constant current source, no ballast or starter is needed. In general, the lamp tube above T8 can be installed in the lamp tube because the lamp space is large enough.
2. The three wires of the led lamp are connected to the zero wire and the fire wire. Connect the zero wire and the hot wire, and one is the ground wire, the color of the ground wire is yellow and green, while the color of the hot wire is red, and the color of the zero wire is blue. The hot wire is actually equivalent to the positive pole, this line is with voltage, and the zero wire is connected by the electrical circuit, which is equivalent to the negative pole.
3. The connection of the three wires of the led lamp: be prepared for safety, cut the power supply, put on protective gloves, and connect the current-limiting resistance to the L line of the lamp. Carefully tear off the line connected to the lamp tube, then use a tool to remove a small piece of insulation from the L and N lines of the lamp, and finally connect it with the L and N lines of the lamp point to point.
4. distinguish three lines according to the color of the lines. Pre-determined PE line as long as the two-color line is generally grounded PE line, and then find hot color line, such as brown, yellow and so on, hot color line is generally hot line L, cold color line, such as green, light blue, white, etc., generally zero line N.
5. It is very simple to connect the three wires of the LED lamp. First of all, we need to distinguish between the hot wire, the ground wire and the zero wire. At the interface of the LED light, we can see a telephone pole, and then we need to cut off one end of the port of the hot wire, and then connect the three wires in series to complete the connection.
6. The three wires of led lights of electric vehicles are connected in this way. First of all, find a battery wire through the switch, switch another wire to the lamp as the positive pole, and the lamp sit on the other wire to connect to the negative pole of the power supply. One wire is connected to the right-hand headlight switch to the far and near switch and two wires to the lamp holder, and the lamp holder is negative and Hu connects to the negative electrode of the electric car.
