How to Cut LED Lights

How to Cut LED Lights? You can cut the LED lights, but the thing is that how do you miss that? With a pair of scissors, you can easily cut apart LED strip lights. At the end of each LED is a pair of copper dots. All of the LEDs will function if you cut between the dots. After that, you may either solder or use a fast connector to connect the LEDs to a power supply. All of the LEDs should light up in a colorful pattern if they are connected correctly. As a result, you can accurately cut your strips here without causing damage.

How to Cut LED Lights

You might believe that cutting LED strip lights is an easy task. On the other hand, many others have made the error of not missing appropriately, causing their perfect lights to be damaged.

Cutting of LED Lights Guide:

To properly cut your LED strip lights, follow this guide.

Whatever type of LED strip light you have, you can be sure of one thing: you’ll be able to cut it to the length you want. There are straight or dotted black or white lines across your LED strip that show where you can cut. Because the circuits are isolated here, it is easy to miss these lines. As a result, you can safely trim your strips here without causing damage.

Because different types of LED strips have distinct cutting lines, LED will vary the cutting lines on each. Most LED strips, on the other hand, feature cutoff lines every three LEDs.

Copper dots can also be found on both sides of the black cutting line. They make a symmetrical pattern. There are two copper dots; however, on color-shifting RGBs, there are four copper dots. The cutting line will be visible between these copper spots if you locate them. Before you begin cutting, check to see that your lights are operational. This is because cutting your LED will almost certainly avoid your warranty.

Then figure out how long you’ll need the LED strip for your project. Measure the area of your home where you want to install your LED strip lights carefully. Then, for a proper installation, cut the strip on the closest line to your necessary length. Cut your LED strip on the line with a pair of scissors or a sharp knife. Slow down, so you don’t accidentally chop off something else. If this happens, you will not be wounded, but your LED strip may be destroyed.

LED lights

A LED is a semiconductor device that operates on the electroluminescent principle. H.J Round of Marconi Labs coined the term electroluminescent in 1907 after merging Silicon Carbide and a Cat Whisker detector. Commercial LED was initially used to address the shortcomings of incandescent lighting, neon indication lamps, and a 7-segment display. The key benefit of employing these LEDs is their small size, long lifetime, and good switching ability.

Structure

LED can be made by combining three colors, green, red, and blue, or employing phosphor material. The LED comprises three internal terminals (RGB in color) and a lengthy lead used as either a cathode or an anode.

Cut of LED lights

LED Strip Lights are used in the vast majority, and they can be cut at the point where dots are marked at the end of the circuit. Cut lengths vary between products.

Long reels of LED strips are commonly marketed. LED strips range in length from 3 to 16 feet. But what if they’re excessively long? Is it possible to cut LED strips to fit your needs?

Is there a specific length that you require for your project? The good news is that LED strips can be reduced in size. Stop right now, before you take out your scissors! Before you cut the length of your LED strips, there are a few things to consider.

WORKING

LEDs are just tiny light bulbs that can be easily integrated into an electrical circuit. They don’t have filaments that burn out, require less electricity, and don’t become as hot as incandescent bulbs. They’re powered entirely by the passage of electrons in a material, and they last just as long as a conventional transistor. An LED’s lifespan is thousands of hours longer than that of an incandescent bulb. Because of these benefits, small LEDs are one of the most widely utilized technologies for lighting LCD televisions.

Summary

A light-emitting diode (LED) is a semiconductor device that works on the electroluminescent principle. LEDs can be created by combining three different hues, green, red, and blue, or phosphor material. The vast majority of LED Strip Lights are used, and they can be cut at the place where dots are designated at the end of the circuit. The length of the cut varies depending on the product. LEDs are miniature light bulbs that can be easily integrated into electrical circuits. The lifespan of an LED is thousands of hours more significant than that of an incandescent light bulb.

Advantages of LED Lights

LEDs have several advantages over traditional incandescent bulbs, the most important of which is their efficiency.

The light-production process in incandescent bulbs includes heat generation (the filament must be warmed to illuminate). Unless you’re utilizing the lamp as a warmer, this energy is utterly lost because much of the available electricity isn’t used to produce visible light. LEDs, in comparison, have very little heat. A far higher percentage of electrical energy generates light, resulting in significantly lower electricity demands.

LEDs provide more lumens (or visible light) per watt than typical incandescent bulbs. In comparison, an LED bulb can produce the same output with only 6-8 watts. The identical LED bulb can last 25,000 hours, whereas a 60-watt incandescent bulb will likely only last 1,200 hours. To put it another way, one LED bulb can last as long as 21 60-watt incandescent lamps if they are all used simultaneously.

Because LEDs are made of advanced semiconductor materials, they were previously too expensive to employ in most lighting applications. However, following the year 2000, the cost of semiconductor devices fell, making LEDs a more cost-effective lighting solution in various circumstances. While they are initially more expensive than incandescent lights, their lower long-term costs may make them a superior investment.

Several businesses have started selling LED light bulbs designed to compete with incandescent and compact fluorescent ones, promising extended life, intense light, and an incredible energy economy.

Power Supply of LEDs

Installers of intelligent lighting systems can instead utilize LED lights or strips with input ratings of 12VDC or 24VDC and power them with an AC-DC power supply or driver that also offers dimming control. A complex control interface, such as the DALI (Digital Addressable Lighting Interface) standard, could be included. This allows users to send lighting control commands to a single light or a group of lights via a network.

Power

It’s possible to customize the fading sequences and brightness levels. It’s also possible to create scenarios in which a single broadcast command turns on numerous lights simultaneously at different levels. There could be a setting in a theatre for dim lights above the crowd and strong lights above the stage. The final job of an LED lamp power supply’s control input, regardless of how sophisticated it is, is to translate the control signal level into a corresponding brightness level for the powered LED (or LEDs).

The brightness of an LED is proportional to the current flowing through it, and it is usually adjusted using pulse width modulation (PWM). The LED’s peak current in mA is chosen, and the PWM duty cycle is varied to regulate it. The light output of an LED in foot-lamberts (fL) may be shown to be linearly related to the duty cycle.

This chart was created as a rough reference to show which power supply is required for different strip lengths with varying consumptions of power (measured in watts per foot). This table contains merely examples and is not meant to be used as a buying guide!

Application of LEDs

LED lights can be designed to meet the device or user’s requirements. Application-specific LEDs, on the other hand, are pretty widespread due to their flexibility to be customized. These application-specific LEDs, on the other hand, are divided into the following categories:

  • RGB or Red Green Blue

  • Bi-Color and Tri-Color

  • Flashing

  • Lighting

  • Alphanumeric

Frequently Asked Questions (FAQS)

1. Is it possible to cut LED lights and have them still work?

Yes, as long as you cut along the designated lines, LED strip lights will continue to work after they’ve been cut. If you miss anywhere else on the LED strip, that circuit will stop working, and maybe the entire strip.

2. What if I cut my LED lights?

LED Strip Lights will continue to work after they have been cut due to their design. This is because at each cutting point, their circuit is closed. You’ll have to conduct some soldering if you’re missing your strip lights into two halves and intending to utilize them as two independent installations.

3. Can you reconnect cut LED strips?

If the LED light strip you bought can be cut, the portion you cut off is no longer usable. If you want to reattach them after cutting them, you’ll need an extra four-pin connector… This item is not usually included in LED light strip sets and must be purchased individually.

4. Why are half of my LED strip lights out?

A defective power supply could be the cause of the LEDs not lighting up at all. Solution: If you have multiple power supplies, try plugging in a different power source to the same strip to check if it works now. If it does, you’ve got a faulty power supply and will need to replace it.

5. How do LED lights work after cutting?

With a pair of scissors, you can easily cut apart LED strip lights. At the end of each LED is a pair of copper dots. All of the LEDs will function if you cut between the dots. The LEDs can then be connected to a power supply via a fast connector or by soldering.

6. Can I rejoin the LRD strips after cutting? Is that possible?

An additional 4pin connector is required to rejoin LED light strips after they have been cut. This item is not typically included in LED light strip sets and must be purchased individually.

7. Do LED lights work if you cut them?

Yes, as long as you cut along the designated lines, LED strip lights will continue to work after you’ve missed them. When you cut somewhere else on the LED strip, that circuit will stop working, and maybe the entire strip.

8. Can you repair cut LED lights?

Is it possible to cut and join LED strip lights? Yes, you can rejoin strips that have been severed previously. To join two strips together, you can use a quick connection (available at any hardware store) and some adhesive, or you can use a quick connector (available at any hardware store).

9. Can LED strips catch fire?

Even though led strip lights are hot to the touch, the chances of catching fire are extremely remote. Because incandescent bulbs have a filament that releases a lot of heat, they can catch fire if they become too hot. On the other hand, LED lights create light at a lower temperature, so they don’t catch fire as quickly.

10. Is it safe to cover LED lights?

It’s tempting to drape a sweater or scarf over those bright lights to hide them, but this isn’t a good idea. The fabric tends to retain heat, which can cause your electronic device to overheat and possibly catch fire.

11. Are our LED Strip Lights bad for your eyes?

Leaving lights on while you’re gone not only puts you at risk of a fire but also raises your electric bill. Light bulbs can get extremely hot and, if not handled correctly, can cause a fire. When the bulbs were left on, the plastic would melt, releasing hazardous gases and igniting adjacent things.

Conclusion

It’s not difficult to cut your LED strips to the length you want. All you have to do is pay attention to their cutting lines. You may change the size of LED strip lights by cutting or attaching them to match your installation needs. If you need shorter pieces, carefully cut them. Attach more strips to your existing ones if you need them to be longer.
