Wiring diagram of the 220V LED strip to the mains: correct installation of the backlight
The distribution of light has always been important in the design of rooms. With the advent of LED technologies, LED strips began to be used in almost every interior. With their help, you can visually change the geometry of the room, highlight the contours of furniture, illuminate decorative elements. The tape is easily attached to the surface and can be used to frame complex curved trajectories. The wiring diagram of the 220V LED strip to the network is simple, which allows you to install it yourself.
Advantages and applications of LED strips
The LED strip is a flexible printed circuit board with LEDs soldered to it. The scope of application of such lighting includes outdoor advertising, road signs, interior and landscape design, electronic displays, illumination of portable devices and even LED wallpaper.
LED strips have received such wide use due to a number of unique advantages:
- easy and quick installation – most tapes have double-sided tape on the reverse side, which greatly facilitates the fixation of the loop to any surfaces;
- cost–effectiveness of use – LEDs are characterized by low power consumption;
- the duration of operation is a long service life, unlike traditional incandescent and fluorescent lamps;
- environmental safety – do not contain substances harmful to health and the environment, due to the uniform distribution of light, they do not have a negative impact on vision;
- the ability to function in severe operating conditions – withstand small vibrations, shocks, moisture ingress, low temperature;
- the small size, flexibility and moisture resistance allow the use of ribbons in interior design, landscape design, advertising for illumination distributed along the length;
- no heating – can be used for mounting on any surface: plastic, glass, acrylic and others;
- a wide range of glow shades – thanks to the connection of an RGB LED strip with a controller, you can set any color to the loop.
Using LED strips, you can realize any ideas of the creators of home comfort. They are used for contour illumination of ceilings, floors, steps, as well as furniture and decorative elements: paintings, panels, aquariums. By applying such lighting in hard-to-reach areas, you can beat the disadvantages and emphasize the advantages of the interior.

LED strip for ceiling illumination
Due to its compact size, it does not require large recesses to install the LED strip on the ceiling: a few centimeters are usually enough to place it. Depending on your preferences, you can use monochrome ribbons that emit a glow of the same color or colored loops, adjusting which you can get almost any shades. A photo of the ceiling illumination with an LED strip under the baseboard illustrates ways to highlight the contours of the room.
The tapes used for illumination, depending on the size of the diodes, are divided into two types: SMD 3528 and SMD 5050. The SMD 5050 tapes have a powerful glow of diodes, each of which is capable of emitting three colors (RGB tapes). With the help of an RGB LED strip with a remote control and controller and with a power supply, not only the glow shades are set, but also the time during which they will change.
There is also a classification of tapes according to the number of diodes placed on 1 meter of flexible strip. The number of them can be 30, 60 and 120. The higher the density of the diodes, the brighter the glow, and, consequently, the amount of power consumption of the LED strip. To illuminate the ceiling, it is recommended to use ribbons, the intensity of the glow of which is insignificant: the backlight will not serve as the main light source, but only gently mark the contours of the ceiling zone.
Pay attention! When choosing the power of the LED strip per meter, it should be taken into account that the greater the brightness, the more powerful the power supply will need and the more expensive the purchase will cost.
Before installing the LED strip on the ceiling (if it is not possible to hide it behind drywall or a stretch structure), a special profile is mounted in which it will be located. The profiles for the LED strip are simply attached and contribute to better cooling of the tape. You can buy profiles for LED strip in retail outlets specializing in the sale of lighting equipment.
LED strips in the apartment interior: photo ideas of contour lighting
Most often, when designing interiors, LED strips are used as local lighting, complementing the main light sources. However, they can also be used to highlight a small specific area, for example, a headboard or a kitchen apron. The option of lighting the kitchen work surface is very popular, as evidenced by numerous photos of the LED strip in the kitchen.
Useful advice! When mounting the kitchen lighting with an LED strip, position it so that the emitted light does not “cut” the eye.
Framing the steps with a ribbon is not only an excellent design solution, but also serves for the safety of moving up the stairs. Such lighting can be used in standby mode. By making it less intense, you can leave the backlight for orientation at night. If you decorate the area where the TV is located with an LED strip, then you will not need additional light sources for comfortable viewing.
With the help of an LED strip, they add volume to glass shelves and shelves, highlighting them from the end. In interiors where natural light is not enough, LED lighting is also used to highlight paintings. This technique will give the work color and originality, and the lack of heating will not harm the canvas itself. Curtains or drapes illuminated with ribbon look spectacular.
The flexibility of the loop allows you to embody the illumination of niches of complex shapes of any size, the outlines of furniture, shelves, mirrors and other interior elements. By decorating transparent glass surfaces with colored lighting, you can create a festive feeling, or, conversely, an atmosphere of relaxation and privacy. It is very convenient to use the tape in closets and dressing rooms.
Self-adhesive LED Strips 220V
The main difference between the 220V LED strip from similar products is that it operates at a voltage of 220V without a power supply. It is connected to the network using special power cables, so you can easily connect the LED strip with your own hands. In addition, you can connect up to 100 m of flexible 220V LED strip using one power cable.
The product is available with various classes of protection, including from dirt, dust, moisture, mechanical damage, adverse weather factors. Self-adhesive tape is produced on a thin flexible base with a thickness of 2 mm, a width of 2 cm and is supplied in reels of 50 and 100 m. The tape can be cut into multiples of one meter without compromising its functionality.
Manufacturers produce models of flexible 220V backlight with LEDs of various types: SMD 3014, SMD 3528, SMD 5050. The types of LEDs affect the brightness of the glow and the power consumption of the tape. The glow colors and light temperature of the models are varied. Special clips are provided for mounting, providing fast and convenient fastening.
For ease of installation, a sticky layer (double-sided adhesive tape) protected by a film is applied to the back of the tape. To fix the LED strip in the right place, it is necessary to remove the protective layer and attach it with the sticky side to the surface. In order to avoid peeling, it is recommended to cut too long segments (more than 5 m) into separate parts.
Pay attention! If the surface on which the LED strip is to be installed is conductive, it must be insulated.
Price of LED strip per meter
Manufacturers produce LED strips that differ in size and density of LEDs, degree of protection, glow colors and other characteristics. You can purchase products in online stores, on the websites of manufacturing companies, as well as in specialized retail outlets. The tapes are delivered in rolls. Depending on the required length, the flexible board can be cut into the desired segments.
In order for the tape to emit a uniform glow, it is worth buying profiles for an LED strip with a diffuser. On sale there are profiles made of aluminum, plastic, with round and rectangular cross-sections, they can be mortise or overhead. For flush mounting, you can purchase corner profiles for the LED strip, which will ensure its protection from mechanical and climatic influences.
The 220 volt LED strips (Duralight) that have appeared on sale are designed for direct connection to a conventional outlet. In view of this, there is no need to purchase a power supply for them, which makes the purchase more profitable. By purchasing a 220 volt LED strip for interior decoration, you can save a lot, given that it consumes significantly less electricity than incandescent lamps, providing the same lighting.

All connections are made with a high-quality cable by soldering with subsequent isolation. Connectors for quick mounting are not used during connection.
In addition, all necessary measurements are carried out for compliance with the illumination requirements regulated by the SNiP. The work is carried out carefully, responsibly and in the shortest possible time. All types of services are guaranteed for up to 3 years. The price for the installation of one meter of monochrome LED strip is about 600 rubles, taking into account the cost of the tape, blocks and consumables. The installation of RGB tape will cost approximately 1400 rubles per running meter.
Wiring diagram of the 220V LED strip to the network
The main reason why it is forbidden to connect the LED strip directly to the 220V household power supply is the high voltage. With this connection, overheating will occur and, as a result, the failure of the diodes. The tapes are designed for a DC supply voltage of 12V and 24V. The required voltage is indicated on the tape itself along its entire length. To obtain the value of the required power supply, mains voltage converters are used.
How to connect a 12 volt LED strip to the mains
The wiring diagrams for 12V and 24V LED strips are as simple as possible and have an identical principle. Before connecting the LED strip to 220V, it is necessary to consider several important points:
When connecting the LED strip to 12 volts, a power supply is used, the main function of which is to lower the voltage in the network from 220V to 12V. The connection is made using a two-core wire: it is clamped with terminals in the power supply unit, and soldered to the tape in the places of the contact pads. The connection of the transformer for the 12 volt LED strip is made taking into account the polarity: plus to plus, minus to minus.
Useful advice! In order to hide the power supply, a certain space is needed. With this in mind, choose the appropriate compact converter models.
Connection of 220V LED strip
The wiring diagram of the LED strip to the 220V network without a converter includes a diode bridge, which serves as a voltage rectifier. A feature of the connection is that the LEDs are connected in one chain of 60 pieces in series or in pairs. The tape should be cut after 50 or 100 cm. If one LED fails during operation, the entire segment will go out, which can be easily replaced.
When installing the LED strip with your own hands, you should first check the current passing through the LEDs. If during measurement it turns out to be more than acceptable, it is necessary to attach another piece of tape. Such a connection should be made very carefully, since the soldering points remain bare and, if accidentally touched, you can get an electric shock. It is necessary to take measures that exclude touching bare places.
Such a scheme is used in 220V LED strips. The factory products are already designed for connection to the 220V network. For safety, such tapes are placed in a transparent PVC tube: this eliminates the risk of touching dangerous contacts and additionally protects against moisture. Due to this, the waterproof 220V LED self-adhesive tape can be used not only in rooms with high humidity, but also outdoors.
How to make a backlight from an LED strip with your own hands
To make an independent installation of the backlight, you will need the following tools: tape measure, soldering iron, scissors, screws, wires. Before installing the LED strip, it is necessary to measure the length of the surface in order to correctly calculate the required amount of tape and consumables.
Fastening of the cut pieces of tape to each other can be done in two ways: by soldering the ends of the tape or by means of connecting connectors. If the illumination segment to be mounted is long, it is recommended to use a parallel power supply scheme: when there is a cable from the converter to which the tape is connected. In this case, the intensity of the glow will be the same along the entire length of the backlight.
Installation begins with fixing the profile for the LED strip with your own hands. To do this, holes are pre-drilled in its base, through which the profile is fixed to the surface using self-tapping screws. Then, a tape is attached to the side or bottom surface of the profile (the side on which the adhesive base is applied). The wires and the power supply are hidden in niches or interior elements, and the indicator (IR) is left visible.
There are various options for making LED strip lamps with your own hands. The easiest way is to make a horizontal model to illuminate the countertop area in the kitchen, where products are usually cut. For manufacturing, an aluminum corner with holes made and a piece of tape of the appropriate length will be required. If the profile is not used for illumination, before installing the LED strip in the kitchen, the surface is thoroughly degreased.
Knowing the principle of operation of the LED strip, and using its flexibility, it is possible to design lamps of various shapes on any surface. They will enhance the lighting range and give a special effect to the design of the entire room or individual elements. In addition, from the products created by their own hands, there is always a sense of warmth and comfort.
