LED light strip installation process

1. Check the light strip: First, determine the length to be installed, and then take an integer and intercept it. This kind of light strip has a unit of 1 meter. It will not affect the circuit until it is cut off at the notch. If it is cut at will, one unit will not light up.

Example: If a length of 7.5 meters is required, the light strip needs to be cut to 8 meters.

2. Link plug: The LED itself is a diode, driven by DC, so it has positive and negative poles. If the positive and negative poles are connected reversely, it will be in an insulated state and the light strip will not light up. If the connecting plug does not light up when it is powered on, you only need to disassemble the other end of the light strip.

3. Placement of light strips: The light strips are packaged in trays. The newly disassembled light strips will be twisted and difficult to install. You can straighten them first and then put them into the light trough. Since the light strip emits light from one side, uneven light and dark will appear if it is placed unevenly. Be careful especially around corners.

How to install LED light strips

1. Indoor installation: When LED light strips are used for indoor decoration, installation is very simple because they do not have to withstand wind and rain. Take the LED light strips produced by Guanghong Electronics as an example. Each LED light strip has self-adhesive 3m double-sided tape on the back. During installation, you can directly peel off the sticker on the surface of the 3m double-sided tape, and then fix the light strip where needed. Where to install, just press it flat with your hands.

2. Outdoor installation: Outdoor installation will be exposed to wind and rain. If 3m glue is used to fix it, the 3m glue will decrease over time and cause the LED light strip to fall off. Therefore, outdoor installation often uses card slots to fix it. Where cutting and connection are required, the method is the same as for indoor installation, except that additional waterproof glue is required to consolidate the waterproof effect of the connection points.

3. Power connection method: The general voltage of LED light strips is DC 12v, so a switching power supply is required. The size of the power supply is determined according to the power and connection length of the LED light strips. If you do not want each LED light strip to be controlled by a power supply, you can purchase a relatively high-power switching power supply as the main power supply, and then connect all the input power supplies of all LED light strips in parallel (if the wire size is not enough, you can extend it separately). All are powered by the main switching power supply. The advantage of this is that it can be controlled centrally. The inconvenience is that it cannot achieve the lighting effect and switch control of a single LED light strip. The specific method can be measured by yourself.

4. Controller connection method: LED marquee strips and RGB full-color strips require a controller to achieve changing effects, and the control distance of each controller is different. Generally speaking, the control distance of a simple controller is 10 to 15 meters, the control distance of the remote controller is 15 to 20 meters, and the longest distance can be controlled to 30 meters. If the connection distance of the LED light strip is long and the controller cannot control such a long light strip, then a power amplifier is needed for tapping.

Things to note when installing LED light strips:

1) Do not turn on the power to light up the LED light strips before the entire roll of LED light strips is removed from the packaging or piled up;

2) When the LED light strip needs to be cut according to the length of the on-site installation, the light strip can only be cut at the place marked with scissors, otherwise one of the units will not light up. Generally, the length of each unit is 1.5-2 meters;

3) When connecting to the power supply or connecting two light strips in series, first bend the head of the Licai lamp to the left and right to expose about 2-3mm of the wires in the light strip. Use scissors to cut it clean without leaving burrs, and then use a male needle to connection to avoid short circuit;

4) Only LED colorful light strips with the same specifications and the same voltage can be connected in series, and the total length of the series connection cannot exceed the maximum allowable length;

5) When LED light strips are connected in series, try to light one section after each connection, so as to promptly find out whether the positive and negative poles are connected incorrectly and whether the light emission direction of each section of light strips is consistent;

6) The end of the light strip must be put on a PVC tail plug, and then tied tightly with a clamp tape, and then sealed around the interface with neutral glass glue to ensure safety.

7) Because LED has unidirectional conductivity, if you use a power cord with an AC-DC converter, you should first conduct a power-on test after completing the power connection to confirm that the positive and negative poles are connected correctly before putting it into use.
