How Easily You Can Connect Led Strips To Power Supply and mains?

Connecting LED strips to your power supply is the most important part of installing them. 

Everyone can put them on walls or under cabinets, but only a few people can connect them with a power source. 

So this guide will help you learn how to connect LED strips to power supply, how to connect multiple lights to one source and installing lights on the ceiling and under cabinets.

This guide will talk about installing the 12 Volt LED Light Strips so make sure to check the volt of your light as well. So without further ado, let’s dive right in:

How to connect led strip lights to mains?

When it comes to wiring the LEDs to your mains, you need to know that LED strips need LED transformer to be wired to the mains. This is because you are using 12 Volt LED light strips which means significantly lower voltage.

There are different types of transformers for LED lights, and the one that you need will depend on the factors like watts per chip, length of the strip and the total wattage.

Here are different watts of transformers you will need for different chip sizes:

  • 5 watts per meter for 60 small chip size
  • 10 watts per meter for 120 small chips
  • 15 watts per meter for 60 large chips

This means that you will need a 30W LED transformer for 60 small chips, a 60W transformer for 120 small chips and so on.

So once you have the transformer, just connect your LED strips to it and then the transformer to your mains like this:

How to wire led strips to a switch & how to connect led strips to power supply?

Okay so whether you are using LED strips for room lighting or for your office, you will need to wire them to the switch so you can easily turn them on or off. 

This section of the guide will help you wire led strips to a switch and you will also learn how to connect LED strips to power supply along the way. Furthermore, it is going to be a bit technical, so you need to pay close attention.

  • First of all, note the manufacturer’s written amps and the volts for the LED strip you have purchased.
  • Now calculate resistor’s value that you will use for the circuit. The formula for this calculation is; # of ohms = (voltage of source – drop voltage of LED) ÷ the current amps of LED.
  • Now buy the resistor with value very close to the value of ohm you just calculated.
  • Now you need to solder your LED’s positive wire to the resistor. This positive wire is the anode, and it is also the longer wire of the LED.
  • Make sure that the switch is turned off and then connect the resistor’s other side to any one terminal of switch using a copper wire piece by soldering it to the resistor and the switch.
  • Now connect the other remaining terminal of the switch with the positive side of the power supply by again soldering a copper wire between them. There will be a “+” on the power supply’s positive side to tell you that it is the positive side.
  • Take another piece of copper wire and connect the power supply’s negative side and the LED by soldering them to each end of this wire.

This is it, turn on the switch, and the light should work properly. Also, instead of soldering the led wires, you can just use the LED strip connectors.

You can find many LED strip connectors online and can see any video on YouTube to learn how to use LED strip connectors.

How Can I Make a Connection of More Than One LED Strips to a Single Power Supply?

Well now that you know how to connect LED strips to power supply, you don’t need to be technical to connect multiple LED strips to a single power supply

This is because you can just use LED strip splitters to connect multiple 12 Volt LED light strips to a single power supply without tangling yourself in the wires and keeping track of which wire goes where.

You can buy these LED splitters online and just connect the 12 Volt LED light strips’ ends to each end of the splitter and then connect the other end of the splitter to the power source.

How to install led strip lights on the ceiling?

You already know how to connect LED strips to power supply, and you also know how to make connection of multiple strips to a single power supply, so we will not go into technical details. 

Just know that before you order the LED strips, make sure to get the measurement of the areas of your ceiling you want the LED lights to be placed.


Also, keep in mind that there are LED light strips with tape on their backs making it easy to install them on the ceiling, consider them as well.

Now when it comes to using LED strips for room lighting, do not just place them on the areas of the ceiling you measured.

You need to know what effect these lights are producing in the room so first test them without installing in the ceiling or upper part of the wall. Keep adjusting their position until you achieve the desired lighting effect and then install them.


How to connect RGB led strips to the power supply?

When it comes to installing the RGB LED strips to your main, the process is simple and similar to connecting the non-RGB led strips to the main. 

But, the only difference is that you have a remote controller with RGB light to control its color modes. 

So for that, you will need to install an RC unit between the transformer and your LED strip. So it will be like this:

Here the arrows are the wires.


How much power do LED strips use?

There is no particular answer to this question as it varies from strip to strip. 12 Volt LED light strips with 60 LEDs per meter may need 6W per meter, but if you supply it real 12V, it may only consume 5W per meter.

So it depends on the strips, and you can only know this by consulting the technical documentation of the particular strip.


How to install led strip lights under cabinets?

Now that you know how to connect LED strips to power supply, it all comes to your creativity to how you place them in your cabinets to light them up. 

We can provide you with some tips so you can easily put LED strip lights under your cabinet:

  • First of all, just like you measure ceiling or walls when using LED strips for room lighting, you need to measure your cabinets too. This will help you avoid getting excess strips.
  • Now make sure that you have a power source nearby so you can easily connect the LED strips when installed or when testing them.
  • You don’t have to put holes in your cabinets to install brackets to hold LED light strips; you can get the LED lights with tape on their back.
  • Make sure to first place lights temporarily and see how they are lighting up your cabinet and once you get a perfect position, only then drill holes in cabinet walls to make way for the strip to the last cabinet.
  • Lastly, make sure that your adapter is not plugged in when you are putting the LED lights under the cabinets.

Conclusion:


This guide will definitely help you understand how to connect LED strips to power supply, how to connect multiple strips to one power source and how you can place them on ceiling and cabinets. If the information mentioned above is too technical for you, then it is safe to ask a technician to install the lights for you.
