How to connect the LED tape to the power supply?

LED tape has long become an indispensable attribute of our life. In a number of areas of people’s public life, it has become the main source of light. It is also about highlighting monitors displays, and about industrial lighting, and about the lamps of the base type, and even portable lanterns. But it is the LED tape that is the most common type of equipment. And often it is required to connect it to the power supply for various reasons. We will try to figure out how to connect it properly with your own hands to the source of power, as well as consider various situations that may arise in this process.

What you need to consider?

To qualitatively perform such a connection, you must first get acquainted with the characteristics of a specific tape. For example, different models can be equipped with a variety of diodes per 1 meter of the product.

The mentioned characteristic is necessarily displayed in the specifications on the product box. It will directly affect the required power and quality of the resulting light. LEDs can be located in 1 or 2 rows. In addition, they can be protected in different ways:

  • silicone coating;

  • lacquered;

  • Do not have protection.

An important point is that the diode tape receives the required voltage from the power supply to 12 V or 24 V. Therefore, when buying a device, you need to ask how voltage it will require, and purchase a power supply unit or a transformer, which will allow you to connect to a 220 volt network. In addition, 4 factors should be taken into account:

  • length;

  • cutting;

  • polarity;

  • compound.

Now about each of the mentioned moments will say more. If we talk about length, then everything is quite simple. It is enough to simply measure the length of the perimeter that you want to illuminate, and where the tape will be installed. If the distance is greater than the standard roll with a length of 5 meters, then you will need to add an allowance for splicing. Cutting tape for extension can be carried out on certain segments. The order of their location will depend on the number of diodes.

As for cutting, it is often happening that the length of the usual coil is too redundant, and it just needs to cut off some kind of. To connect an LED tape with a length of less than 500 centimeters to a power source, the workpiece should be cut according to said tags. Usually put them every 3 lamp. In most of the tapes just 3 in the block, the lipstices are combined into ligaments of parallel type.

If you cut the tape in any other place, then its functioning will be possible, but in a number of diodes, where the outline is closed, the light will not appear.

Considering the question of polarity, it should be said that, unlike conventional lamps and various techniques, the installation of the LED tape should be carried out taking into account the polarity due to the fact that this device is semiconductor. If this moment does not observe, then the ribbon will not be, it will simply not turn on. To this happen, it will takes the correct connection of the poles on the power supply.

To connect two or more tapes, it is often soldered. If you carefully look at the designated lines for cutting, you can see the specialware for contact. Before attaching parts to each other, they should be cleaned, then produce their processing with a tinning.

After that connect the segments of the ribbon using the wire soldering. It will be best to use a cross section of no more than 2 mm. It should be added that there are ribbon models, which is easy to connect without soldering.

Here will apply switching with the use of special sequels.

How to connect one tape to the power supply?

Now we’ll figure it out in the connection scheme of one tape to the power source. As an example, take a ribbon with a 500 centimeter regulatory length. Most often at the tip of the product from the outside, you can find small parts of wiring for commuting. If they are missing for some reason, it will be necessary to use soldering. For this, the wires with multiple living areas will be required. The cross section should not exceed 2 millimeters. It will be necessary to cut off parts of sufficient length to attach the tape and installing equipment for its submission. To be more convenient, it will be better to take wiring with multi-colored insulation. For example, for “+” red, and for “-” with blue.

Using rosin or a certain acidic composition and solder, it will be necessary to make the logging of the wire from two ends. Now you can perform a saving of the wire to the tape contact regions.

This should be done as soon as possible so that light diodes may not be damaged due to the impact on them of high temperature emanating from the soldering device.

On the segments of the wires, which will be connected to the power supply, it is required to mount the special forces called “NSHVI”. This will provide an opportunity to provide reliable switching with power source terminals.

But to make installation of such devices, it will be necessary to armared by a special tool for crimp, which is usually used in its work electrical professional. Although if there is no possibility to find a similar tool, you can use the most conventional pliers. Places where soldering was carried out, it is necessary to maximize efficiently. It will be best to use the so-called heat shrink tube in this case. On this process of connecting the tape and power supply unit will be completed – it will only be used to check the performance of the obtained fixture.

Methods for connecting multiple ribbons

But there are cases when several ribbons are required to the power supply unit. Then there are only 2 approaches that allow you to implement this idea:

  • using a parallel type connection;

  • Using not one, but several power sources.

Now consider each of these ways in more detail, and we will analyze their features.

Parallel

If you want to make a parallel connection to the power supply unit of several tapes, it will be better to pave one or several trunk pairs of wires to which then you need to connect the conductors of a small length from ribbons.

It will be better here to use twists with subsequent soldering, if we talk about reliability. But most often there is a connection with the use of terminal blocks or connectors. It will significantly simplify repairs if it is necessary.

Besides, With such a switching, you must first make sure that the power supply can withstand the load from 2 or more ribbons. To do this, you can first connect to it with a length of about 700 centimeters, which you want to make from the 5-meter product itself, adding a piece with a length with a length of 2 meters.

The cutting is required by the appropriate markup, which is already applied to the strip. For this you can use the simplest scissors. To connect, as mentioned above, you can use soldering or other options. After the segments were connected, the resulting ribbon is required to switch to the block as a single whole.

Often, the lighting situation develops so that there are several tapes in the circuit that are located from the power supply at different removal. As an example, you can bring the lighting of several zones in a small room or shop window.

To perform a parallel connection of all parts of the contour, there is no particular need to pull the wiring from each tape to the power source. You can connect the main LED tape to the 12-voltage power supply, and several segments can be connected to the main line.

But the main thing here is that the power supply can withstand the load from several connected devices.

With several blocks

Connection with multiple power blocks is usually used in case there are not enough space for mounting more overall power supplies by 24 volts. To connect a light tape like a similar method, you will need:

  • pair of power sources;

  • A pair of amplifiers;

  • LED tape;

  • controller.

Connection will be implemented in a specific order.

  • Part of the product should be connected to the output of the first amplifier “-” “+” and the remaining elements R, G and B to the appropriate connectors on the amplifiers. The second part must be connected to the same connectors, but on the 2nd amplifier.

  • Now the wires from the letter inputs and the advantages of 2 amplifiers should be connected to the controller output. To the “+” and “-” controller login, you should connect the output wires from the 1st power supply, taking into account the polarity. I also need to connect the 1st RGB amplifier. And the 2nd block should be connected in the same way the 2nd amplifier.

  • Now the inputs of power sources should be connected to an alternating current at a voltage of 220 volts. For example, this can be done to the lighting outputs or the simplest outlet. Typically, color marking is used in such devices: the brown wire is responsible for the phase, blue – for zero, yellow or green – for grounding. If there is no confidence that the network ground is done correctly, the connection of this wire is better not to produce.

If the power source is plastic, then in such devices, the ground wire is usually missing at all.

Eliminating errors

First of all, it is worth paying attention to the most common error when connecting 2 parts: the execution is not parallel, and the serial connection. Many believe that it is enough to simply connect a couple of ends of the ribbon in a direct method – and get the desired length. But this switching will not be correct, because the connection of the tapes should only be parallel. In practice, this will lead to an increase in contour resistance. In this case, the tape is or not lit after the connection, or the constantly extreme LEDs are shining very neuro. At the same time, in the initial parts of the voltage will be in excess, which can cause the accelerated failure of these diodes.

Besides, Increased voltage is the reason for the increased temperature of the light diodes, which is also difficult to call a positive point. It has long been proven that the inclined compound of the pair of tape segments becomes the reason for the accelerated wear of all elements and the device as a whole, which significantly reduces its operational period and characteristics, as well as the reliability of such an appliance.

There are other mistakes in this matter, but their occurrence is not a frequent case in contrast to the above described above.
