How to Cut, Connect and Power LED Strip Lights

Where can I cut?

When we use led strips to make products, we often need to cut the led strips according to our own requirements. Normally, the led strip is generally divided into 5V, 12V, 24V according to the voltage

5V is one led per cut

12V, three led per cut,

24V is six per cut

So when we cut, we should pay attention to the position between each scissors mouth? Where can I cut? As shown in the figure below, you can see the scissors mouth of different led strips of 5v 12v 24v.

 

The exception here is the COB led strip, which is a high-density led strip with many different led chips on it. Therefore, the COB of different densities has no relationship between voltage and lamp beads. The position of the scissors opening is clearly visible on the led strip.

How to cut?

Measure the length of the LED strip you need. Cut the led strip at the required position and where there is a scissors mark.

How to connect ?

1.Can be connected with an electric soldering iron

Solder on both ends of the cut wire, and then splice the two ends together. We plugged the soldering iron up to 350 °F and glued a little solder, and placed the soldering iron at the splice for 1~2 seconds to remove the solder and cool it.https://www.youtube.com/watch?v=Bx8yOFPZfnA

 

2. You can also just use non soldering connector not using an electric soldering iron. Next, we introduce three commonly used connectors:

There are three types of connectors: 1 solder-free connector, 2. transparent connector, and 3. Beetle Led Strip Light Connector

 

  • How to use solder-free connector

Cut the led strip to the appropriate position —> peel off the tape of 3M adhesive about 1/4 inch —> insert the light strips at both ends into the middle top position and buckle it —> close the cover —> power on

The advantage and disadvantages of solder-free connector:

It is a very traditional connector. After opening, you can see that it has two wire clips to clamp the two pads of the led strip, so as to achieve the effect of easy power-on after cutting, and it is very convenient to use. However, it also has three shortcomings. It is only suitable for non-waterproof light strips. When you cover it, it is likely to cover one or two SMD led. If it is used in a cabinet light, it may have A small dark area; because it is only clamped inside, his external tension is not enough, and it may fall off in long-term use

Classification of solder-free connector:

Divided by PIN number: 2PIN, 3PIN, 4PIN, 5PIN

Divided according to shape: cross, L-shaped, T-shaped, one-end wiring, two-end wiring.

  •  How to use the beetle Led Strip Light Connector:

Cut the led strip to the appropriate position —> peel off the tape of 3M adhesive about 1/4 inch —> peel off the glue at both ends to expose the PCB board —> insert the light strips at both ends into the middle top position May —>press the lid tightly—>power on.

Beetle Led Strip Light Connector advantages and disadvantages:

Beetle buckle is very suitable for waterproof led strip, but its volume is relatively large, when used with aluminum trough, it will not fit into many smaller aluminum troughs because it is too large. In addition, there will still be a little light blocking.

  • How to use the new transparent connector:

The third is a newest connector, this connector is suitable for 2PIN conventional light strips, Cut the led strip to the appropriate position —> peel off the tape of 3M adhesive about 1/4 inch —> insert the light band at both ends into the middle top position —> insert the pin down, the led strip PCB board is penetrated —> Power on

The advantages and disadvantages of transparent connectors:

The advantage of this transparent connector is that there are two buckles on it, which can easily penetrate the PCB. Once connected, it is not easy to fall off. Another advantage is that it is transparent as a whole and will not have any light blocking. But he does not have 4PIN and 3PIN models, which is not applicable to RGB and RGBW light strips, only monochromatic light strips.

Different types of transparent connectors:

Divided according to different widths: three specifications of 6 width, 8 width and 10 width, and the board with the board with wire can be connected with a head with a wire and a middle with a wire
