Find the wiring diagram of double-control led tricolor lamp
In general, the tricolor light is controlled by a sectional switch inside the lamp, as shown in the following picture, but the switch that actually controls the light must be connected to the fire line. If you want to install a double control switch, the wiring control method should also be controlled on the hot line. You can refer to the wiring mode in the figure below to try it. I hope it can help you.
The wiring diagram of the double control lamp is as follows: the two contacts of the two single-pole and double-throw switches are connected respectively, that is, the contact 1 of the switch 1 is connected with the contact 1 of the switch 2, and the contact 2 of the switch 1 is connected with the contact 2 of the switch 2. Then the knives of the two switches are connected to the two ends of the lamp as the two ends of the whole switch.
Touch switch of three contacts the two points on the right mark the hot wire input fire wire, the hot wire output lamp, the left zero line input zero wire, and the zero wire reconnect the lamp. Zero lines are directly connected to lights and do not require input and output.
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.
Tricolor LED must have four pins. I don’t know if you have a common cathode (negative pole) or a common anode (positive pole). Anyway, one is collinear, and the other three correspond to three colors. There should be a label on the connection driver. If the driver also has the same color as the lead, it is ok.
The wiring diagram of the three-lamp, three-switch and double-control switch is as follows: first, determine whether there is a power supply in the switch box. If there is no power supply, there should be three wires, two tie wires and one lamp cable in the switch box below. If there is a power supply, it is two tie wires and a power cord.

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 wiring of the three-wire proximity switch: the red (brown) wire is connected to the positive end of the power supply; the blue wire is connected to the 0V end of the power supply; the yellow (black) wire is the signal and should be connected to the load. The other end of the load is connected like this: for NPN proximity switch, it should be connected to the positive end of the power supply; for PNP proximity switch, it should be connected to the 0V end of the power supply.
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.

If you have a multimeter in beep gear, you can find out which one is positive and negative by direct measurement. LED lamp beads will have bright light when tested correctly. Here are some pictures for you to compare with yourself. You’d better take a picture to take a look at it for you. If you don’t have a led lamp transformer, you can’t directly use 220V voltage, otherwise it will explode.

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.
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.
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.
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.
The 200w LED light has three red, yellow and blue wires. How to get it?
The red wire is connected to the fire wire, the blue line to the zero wire, and the yellow and green ground wire.
In the first case, generally speaking, red wire, yellow ground wire and blue zero wire. In the second case, green zero wire, brown wire, yellow ground wire. No matter what the situation has reached a certain standard, the yellow wire grounding wire. As a second-class lamp, there must be a bottom line. So be careful.
The red one is the hot wire, the blue zero wire, and the yellow (actually yellow and green ones have a green wire) is the ground wire.
Compare with the logo or derive the use of the three wires from the circuit, it is recommended to follow up with the drawing here.
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.
