How to cut, connect and power led strip lights

What is led strip light?

The flexible LED strip light is made of FPC as the assembled circuit board, and the high-brightness LED is used as the light source. The thickness of the LED strip light is only the thickness of a coin, and it does not occupy space. The flexible LED strip light can be cut, and it can also be extended without affecting the light. Because the FPC material is soft, the LED strip light can be bent, folded, rolled, moved, and stretched freely in three-dimensional space without breaking. It is suitable for irregular places and small spaces. Because it can be bent and rolled arbitrarily, it is ideal for various patterns in advertisements and other decorations.

LED strips are widely used in a wide variety of applications. We often need to cut the led strip according to our requirements when we use led strips. But some new beginners do not know how to cut, connect and light LED strips. This article is here to help these people to solve the problem.

The article is mainly divided into 2 parts:
Part 1: Cut, connect and power LED strips by soldering
Part 2: Cut, connect and power LED strips by solder-free connects

Where can I cut led strip?

Before cutting the LED strip, make sure that the LED strip you have purchased can be cut. Otherwise, cutting the LED strip may render it unusable. Also, always remember to disconnect the power supply; it is very dangerous to cut a LED strip that is directly connected to the power supply.

Normally, the led strip is generally divided into 5V, 12V, 24V according to the voltage.
5V is one led per cut
12V is three led per cut
24V is six or seven led per cut

And the led strip will have a black line and a scissors mark at the cut position.
It is very important to cut only on the given cut position when cutting LED strip light. Cutting through or before the cut position will result in no electrical conductivity to the following section.
