Illustration of the method of changing lamp strip for led ceiling lamp
1, how to change the ceiling lamp belt need to first cut off the power supply, and then remove the LED lamp shade, you can see that there is a lamp belt, basically fixed with screws, there may be two or three.
2. the way to change the lamp strip is as follows: remove the ceiling lamp cover, usually a plastic cover, if it is a rotating lampshade, you can rotate it clockwise, if it is a long strip-shaped lampshade, you can find the switch on one side and press the switch to open the lampshade. If there is no cover, just proceed to the next step.
3. Turn off the power supply to prevent electric shock. Remove the ceiling lamp shade, separate the lamp wire from the lamp, and remove the wick. Take the old wick to the Internet or the market to buy the same model, which is safer. Open the package of the new ceiling lamp, open the lampshade, and unscrew the test wire on the lamp with a screwdriver.
Diagram of how to connect led lights
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. 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. 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.

1, first cut off the power, according to the AC voltage, prepare the plug wire connection, there are two LED lights, directly peel off the protective layer to connect, there is no need to divide the positive and negative poles, connect the wire, then wrap it with insulating tape, and then insert it into the socket.
2. it is generally a four-wire module common anode connection method, the specific connection method is a positive wire in, three negative wires out (the corresponding cable color is red, green and blue) the controller can generally carry a lamp belt of more than 30 meters, which will burn the controller if it is too long.
3. When the LED lamp belt device is installed, it is usually placed in the lamp slot and straightened, and it can also be fixed with string or wire. If you need external or vertical installation, you need to buy additional clips and tail plugs. The original clip is fully transparent, it is best to apply waterproof glass glue to the tail plugs and plugs after installation, so that the waterproof function is better.
4. 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.
Installation steps and precautions of LED lamp belt (with illustration)
Household LED lamp belt indoor installation: LED lamp belt is used for interior decoration, because it does not have to withstand wind and rain, so the installation is very simple.
The installation method of the lamp belt is as follows: first determine the length of the installation, and then intercept the whole number. Fixed, because the lamp belts are installed in our ceiling grooves, so the way of installation is very simple. For example, our more common LED light belt, most of their backs are self-adhesive tape.
The first step is to determine whether the installed lamp strip / LED light strip uses high voltage or low voltage electricity (considering the power safety, it is best to choose the low voltage LED light strip). After choosing the low voltage LED light strip, you need to observe that there are two dots for every three light beads on the lamp belt and weld the line to the dot.
First of all, prepare the tool, cut off the power, remove the LED lampshade, you can find that the original lamp belt is fixed on the base of the lamp with triangle screws, in addition, there is a special power buckle and plug nearby.
Led lamp belt installation tutorial is first of all to cut the lamp belt, every meter on the lamp belt will have a space, this place is used as a cutting place, if it is cut in other places, it will directly destroy the circuit of the lamp belt, directly leading to the lamp belt can not be used.
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. Connect the negative wire of the power supply with the positive wire of the LED lamp strip.
