How to connect the led light strip _led light strip installation wiring diagram

LED light strips have gradually emerged in the decoration industry because of their light weight, energy saving, softness, long life and safety. So how do you wire the LED strips? The following briefly introduces the installation and wiring method of the LED light strip.

Self-adhesive 3M double-sided tape is attached to the back of each lamp strip. When installing, you can directly remove the sticker on the surface of 3M double-sided tape, then fix the lamp strip in the installation position and close it with your hand. As for some places that need to turn or the length of the lamp strip is inconsistent. The LED light bar is a circuit structure consisting of three LEDs in a series-parallel manner. Each of the three LEDs can be cut, and the length can be cut off, and the short can be soldered.

(1) The first type of lamp wiring method: (welding method)

The first step is to determine whether the installed lamp strip/LED strip is using high voltage or low voltage (in view of the safety of electricity, it is best to use a low voltage electric start strip). After using the low voltage LED strip, you need First observe that there are two dots on every three lamp beads on the lamp strip, and solder the wire to the dot. However, some children's shoes use high-voltage lamp strips for brightness and illumination. If the high-voltage is used, the plug is plugged in and connected to the home power supply of two hundred and twenty volts.

(2) The second type of lamp wiring method: (terminal wiring method)

Firstly, all the lamp beads are mixed and connected in series with a number of resistors. This is a 12V DC power supply lamp strip. The two output lines of the 12V DC power supply (regulated or unregulated) can be directly connected to the lamp strip. Plug the power plug into the AC power socket on the negative terminal, or use a 12V battery pack to directly drive the lamp.

(3) The third type of lamp wiring method: (drive connection method)

First of all, the lamp strips in which all the beads are connected in series need to be equipped with a capacitive ballast constant current driver (there is also a better switching constant current driver suitable for driving low voltage strips). Insert the two pins of the driver plug into the core of the lamp with two leads, and plug the driver into the 220-volt AC power socket.

When the LED light bar is used outdoors, it will be attacked by rain and ultraviolet rays. If it is fixed by 3M glue, the 3M adhesive will be reduced for a long time and the LED light bar will fall off. Therefore, the installation of the outdoor LED flexible light strip is often adopted. The way the card slot is fixed. The place that needs to be cut and connected is the same as the indoor installation, except that it needs to be additionally equipped with waterproof glue to consolidate the waterproof effect of the joint.
