LED strip lighting is a popular lighting solution that offers versatility and adaptability for different lighting needs. In this article, we will discuss how to easily extend the LED strip light.
Switching off the LED strip light
The LED strip consists of small LED lights connected together to form a strip. The led strip is divided into modules with cut-off points at the end. The modules are electrically paralleled in the led strip, allowing the led strip to be cut and resumed.
So if you cut anywhere other than where you cut, the whole cut part of the series will be dark.
The LED strip can therefore be cut off at intervals, depending on the LED strip used… The cut-off points can be anything between 2.5 – 30 cm. The cut-off points are usually marked on the strip with small scissors or a line.
Cutting the LED strip – Cut the strip at the relevant point using sharp scissors.
Led strip lighting soldering basics
Soldering a Led strip light is not impossibly difficult. You just need to understand the basics. Here are the instructions for soldering the Led strip.
Soldering iron
Almost anything will do as a soldering iron, and for years I used to use a cheap 8 euro soldering iron myself. If you do a lot of soldering, it’s certainly worth getting a better quality flask. But here are the main things to remember:
- Keep the flask as hot as possible – soldering is done quickly and not by heating for a long time
- Use the narrowest possible soldering tip – it makes it easier to get the heat only where you need it
- Keep the soldering tip clean – If there is burnt plastic, etc. on the soldering tip it will prevent heat production!
Soldering
There are many different types of watering can on the market. The narrowest possible tin helps a lot when soldering Led strip lights. We use 0,5mm thick tin ourselves. Tin is sold in rolls and tubes.
There are many types of soldering tin available, but if you do a lot of soldering, leaded tin is best, e.g. in a 30/70 ratio. However, leaded tin is no longer sold to consumers, and retailers require you to have a Y-code. The ban is due to the toxicity of lead. You’ll do fine with other soldering stacks but the stickiness is just weaker, so it takes longer to warm up.
Whenever you do soldering work, remember to ventilate your workstation!
Led strip soldering
There are a few basic things to remember when it comes to the actual watering process, to make it as easy as possible.
- The tip of the soldering tin is always held on the surface where you want the tin to be.
- Hold the tip in place and bring the tin along the tip of the flask, right at the joint between the surface to be soldered and the tip.
Lead the soldering iron from the side to the seam between the piston tip and the copper. - If the surface to be soldered is hot enough, the tin will run onto it. So don’t try to tin too hastily and make sure the soldering iron is hot enough. Test that the tin melts easily against the piston.
- Always carry out soldering work in good light and in such a way that you can see the surface well, and do not hit the LED circuit directly with the tip of the piston, as this can damage it.
- When connecting a wire to a strip of led or two ends of a strip of led, first solder the tin to both surfaces, i.e. the wire and the strip of led separately. I will then combine them together.
First solder the wire and copper surface separately before splicing
LED strip light extension
For LED strips, there are connectors that allow the strip to be continued after it has been cut. Connectors sound easy, but from years of experience I can say that the only sustainable way to reconnect an LED strip light is soldering. The connectors become loose, dust and grease get in between and they are difficult to find.
Another problem with off-the-shelf connectors is the versatility of LED strip lights, as there are many LED strip lights on the market and each one can have solder points at different points and the width of the LED strip light itself varies.
Why continue with the led strip lighting?
The LED strip can be extended and cut off for a variety of reasons. Most commonly, cutting and extending is done when the tape needs to be extended to a tighter gauge or when there is an angle at the point of installation.
If you want to use the cut strip in several different places or if you want to adapt the length of the strip to different lighting needs you will have to solder them with soldering irons. On the other hand, learning the skill is useful and not impossibly difficult for basic LED strip lighting.
RGBW and RGBCCT may cause difficulties because of the 5-6 small solder points at the junction. How then to continue the light strip? Let’s now look in more detail at tools and soldering.
Tools needed to extend the Led strip light
- Scissors – Sharp for cutting LED tape
- Soldering iron – Narrowest possible tip
- Soldering stacks – As thin as possible
- Silicone or shrink stick – to protect damp areas
- Small hacksaw – For cutting aluminium profiles
These tools can therefore be used to extend the LED strip light. Silicone or shrinking plugs are required for wet room installations. In a dry room, you can just use electrical tape, or in many cases you can do without.
Steps to extend the Led strip light
- Measure the required length to the installation site
- I set the soldering iron to heat up, as hot as possible
- Cut led aluminium profiles
- Cut the led strips to size. Please note that the cut-off distance of the Led strip can be anything from 2,5 – 30cm, so please take this into account. In addition, 1-2 cm space is required for the wire connection at the end of the Led profile.
Remember to leave space for wires and solder in the profile. - If you are using a wet room LED strip, cut away the protective layer from the solder points and clean off any adhesive stuck to the copper by lightly scrubbing if necessary.
- Solder tin to the soldering points on both ends of the LED strip.
First add the soldering iron to the strip - Place the ends of the extendable LED strip light opposite each other. Be careful that + and + are opposite, otherwise the led strip will be shorted from that point onwards and the light will not come on.
Remember to check that the ends of the tape are facing the right way! - heat between the ends until the two solder stacks of the led strip fuse together. Pull out the soldering iron, but DO NOT MOVE the led strips until the tin has hardened, otherwise the solder will fail.
Heat the soldering irons well - If the extension comes out, the extension should be protected with either a transparent shrink sleeve or silicone.
LED strip light extension at corners
The most common need for cutting comes at corners. The LED strip light does not bend 90° to the side. It should be cut and make a small splice with a soldering iron and cross the bend that way.
LED strip repair
If you have a faulty piece of LED strip light in the middle, it can be repaired with the same soldering instructions. We’ve gone through the process of replacing the part in more detail in the LED strip light cut-off guide.
Common mistakes and how to avoid them
One of the most common mistakes is cutting the led strip in the wrong place. It is important to cut the strip at the marked cut-off points to avoid damaging the strip and to allow it to be reattached.
Another common mistake is incorrect handling of the led strip after cutting. It is important to handle the ends of the cut led strip correctly so that they are not damaged and the strip works properly. This applies to IP65 LED strips that are installed outside. An unprotected cutting head will collect moisture and damage the LED strip.
Summary
LED strip cutting is a simple process that requires only a few tools and basic knowledge of LED strip lighting. Switching allows the strip to be adapted to different lighting needs and spaces, making the LED strip a very versatile lighting solution.
Hopefully this article will help you understand how to disconnect and reconnect the LED strip light.
