How to connect the led switching power supply
1. 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.
2. The wiring steps of LED lamp are as follows: 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.
3. The connection mode of the input line: it usually needs to be connected to the municipal power supply, and the voltage and current parameters of the power supply can be determined according to the identification or instructions of the power supply. generally, the input line of the power supply needs to be connected to the hot line and zero line of the municipal power plant. The connection mode of the output line: usually need to be connected to the lamp strip of the LED light box or other LED lamps.
4. LED lamp wiring can be divided into three types: two-end wiring, single-ended wiring and staggered wiring; before wiring, it is important to know that the hot wire is generally red, the zero line is generally blue, and the yellow-green ground wire is alternate.
5. Led lights generally use 220V voltage. When installing, you should first draw the switch of the internal contact of the lamp port out of the hot wire, and then the side contact leads to the zero wire, which leads to one end of the wire connection switch and the other end of the zero wire connection switch. After fixing the wire and interface, then install the led lamp belt.
6. First find the main switch of the power supply at home. In general, the power switch at home is in the position of the doorway. If you pull the switch, the power will be cut off. Try to see if there is electricity in the pen or turn on the electricity facilities at home to see if the power is off. After confirming it, we will start our next step.
Installation and wiring method of led Lamp
1. The wiring steps of LED lamp are as follows: 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.
2. 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.
3. 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.

3. If the AC voltage is 220V, just connect the prepared plug cable directly to the power supply line of the led lamp, then wrap the interface with electrical tape and plug it into the socket.
4. How to connect the LED lamp power cord? first set the current limiting resistance to the negative pole of the power cord. Then separate the positive and negative wires of the LED lamp. The skin of the positive and negative pole line of the LED lamp is removed by the peeler. Connect the negative wire of the power supply to the positive line of the LED lamp.
5, LED lamp installation wiring method needs to be carried out according to the actual situation, if it is a general LED lamp, there are generally hot wire (L) and zero wire (N), the following is the wire connection method: first of all, loosen the terminal in the light board box. Connect the hot wire (L wire) to the hot end of the terminal, usually red or brown wire.

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 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.
How to choose Intelligent Power Saving device WSDQ-LD-50 for Street Lamp
1. Battery selection at present, conventional batteries are classified as colloidal lead-acid battery box lithium iron phosphate battery. At first, everyone chose a lead-acid battery, which was relatively heavy. For convenience and safety, they chose to bury the battery next to the street lamp. The battery was stolen after construction and installation. As a result, lithium batteries appear.
2. Choose and buy from regular manufacturers. Selection method: choose the regular municipal solar street lamp manufacturers, do not covet the solar street lamp price is cheap. Prevent the battery from overcharging and discharging, and prolong the battery life. The first anti-battery polarity is reversed. Prevent the internal short circuit of load, controller, inverter and other equipment.
3. Adopt the method of adjusting the output power of the frequency conversion LED power supply, adjust the working power of the LED lamp, adjust the lighting brightness, achieve on-demand lighting, intelligent energy saving.

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.
