To splice LED strip lights, you cut the strip at designated copper pads (marked with scissors or lines), then use either solderless clip connectors or solder to join them, ensuring you match the polarity (+ to +, - to -) for a secure, working connection, often using small pliers to snap connectors shut.
3.2 How do you cut led strip lights
Step 1: Measure your required length. Step 2: Look for a cut point marked with a ✂️ scissors icon or dotted line. Both can be cut here. Step 3: Unplug the strip from power before cutting.
You can cut them to fit in different areas. Whether to add extra illumination to lower cabinets or a backlight for your TV, LED strip lights can be cut to fit your needs.
To repair by the no-solder method, a clip-on LED connector is used. Such connectors are provided in single-color and RGB strips. Ensure the copper pads on the torn ends are aligned with the metal contacts in the connector, maintaining the correct polarity. After clipping it firmly, test the strip.
How To Connect LED Strip Lights Together
Snapping Grip Connectors onto Wires
The side with the flat surface is for the LED strip; the other side, with bottom indentations, is for the wires. 2. Use 20 or 22 AWG-stranded wires. No need to strip them—the connector's hooks will pierce the insulation to contact the copper wire inside.
If the project requires long sections of LED tape with uniform illumination, parallel connection will be a better choice. On the other hand, in smaller, more compact installations, a series connection may be sufficient and even more economical.
Permatex Clear RTV Silicone Adhesive for Waterproof LED Strip Lights. Silicone adhesive is aspectLED's recommended option for securing our IP68 submersible waterproof strip lights, or for sealing silicone end caps.
Step-by-Step Instructions to Connecting Strip Lights Without a Connector
But many people wonder, can you cut LED strip lights? Well, the simple answer is: yes! LED strip lights can easily be cut to fit the length of your walls, tables, and cabinets.
When connected in this way, the LED strip input voltage remains unchanged. In other words, you can use a 12V power supply to power a 4-ft section of 12V LED strip lights with another 3-ft section of 12V LED strip lights daisy-chained.
Tools You Need to Cut and Reconnect LED Strip Lights
Power supply issue
Cause: After cutting and reconnecting LED strips, the power supply might not provide adequate voltage or current, especially if the strip length has changed significantly. Solution: Calculate how much power the new strip need, change power supply if the old one is not powerful enough.
Cutting Strips in the Wrong Place
Making a wrong cut can cause damage, such as sections failing to light. LED strips are designed to be cut only at specific points, usually marked with lines or scissor symbols. If cut outside these marks, the internal circuits are interrupted, preventing the flow of electricity.
As long as you only cut along the marked cut lines, LED strips – including certain Philips Hue lightstrips – will work after cutting. Many people experience issues with their LED strip lights if they cut outside of these lines. The cut lines are also the safest place to cut LED strips, as the circuits here are closed.
Polyurethane Glue: Polyurethane glue such as Gorilla Glue cures or dries through a chemical reaction that requires moisture for the foam in the glue to expand. LED battery lights and moisture do not mix so it's best to avoid using polyurethane glue when securing LED chip lights to your hobby projects.
Replace Adhesive: If you find your strips peeling off due to worn-out adhesive, don't rush to replace the entire strip. You can refresh its sticking power by applying strong double-sided tape or adhesives specially designed for LED strips.
Theoretically, comparing the same number of chips, SMD 5050 LEDs can offer a light output 3 times that of the 3528 strips, and therefore the 5050 LED is well suited for lighting up areas that may be subject to high levels of ambient light.
The short answer is yes—you can cut LED strip lights. However, it must be done correctly to maintain functionality and safety. In this guide, we'll explore everything you need to know about cutting LED strip lights, including the tools you need, where to cut, and how to reconnect them.
We, at GlowbackLED, recommend soldering LED Strips instead of using quick connectors. Soldering LEDs provide a reliable and permanent electrical connection. Soldering minimizes the error of loose connections which can damage the LEDs and create large headaches.
The longer leg is called the anode (positive). The shorter leg is called the cathode (negative). The anode needs to connect to the power source (positive) while the cathode should be connected to ground (negative).
Step-by-Step Guide to Connect LED Strip Lights
Even if the LEDs have the same specification, they can have poor matching of the I-V characteristics due to variations in the production process. This causes the LEDs to pass a different current. To minimize the difference in current, LEDs in parallel normally have a ballast resistor for each branch.
When connected in this way, the LED strip input voltage remains constant. In other words, you can use a 12V power supply to power a 1-meter length of 12V LED strip and daisy-chain another 2-meter section of 12V LED strip.
