The general reduction in prices for LEDs and matrices based on them determines the widespread use of LED spotlights, and the universal nature of these lamps expands the scope of their application - local areas, parking lots, decorative lighting, and so on.

Schemes for connecting an LED spotlight to a 220 V network are not very complicated - a minimal set of tools and some electrical installation skills are sufficient factors self-connection spotlights to the network.

A little about the design features

Structurally LED Spotlight issued in metal case, inside of which there is an LED matrix and a power supply (driver). In powerful models, the power supply is placed outside, and the LED matrix is ​​connected to a cooling radiator. In low-power LED spotlights, the housing of the lighting fixture is used as a radiator. To connect the LED spotlight to the network, you will need a set of screwdrivers and a cable through which the supply voltage is supplied. The choice of wire cross-section depends on the power of the lighting device, which determines the current strength of the supplied cable. Since LED spotlights have relatively low power, a standard wire with a cross-section of 1.5 mm² is sufficient with a large margin if you need to connect a lighting device with a power of up to 200 W.

Separately, it is worth noting that electrical safety standards require the use of flexible power cables with a multi-core design of internal conductors to connect street floodlights. An example of such a solution is the NYM cable.

Connection diagrams

To connect an external network, the LED spotlight housing is equipped with an input coupling for the cable and a terminal socket for three contact groups - phase (L), neutral (N) and ground. Color marking of wires: phase - red or brown, zero - blue or black, ground - green and yellow.
It is worth remembering that the body of the lighting device is connected to the ground wire of the terminal block, which is determined by the safety measures of the owner of the LED light source. If the supply wire has a two-wire design (phase and neutral), then the grounding terminal in the sockets can be left free.

If you need to connect a spotlight to a lighting circuit through a motion or light sensor, then it means installing the sensors instead of, or in parallel with, a manual switch.

If the sensor is installed next to a lighting device, a cable with an additional core will be required for installation work.

Sequence of work

Directly connecting the cable to the LED spotlight consists of several main steps:

1. Stripping the ends of wires for their installation in a terminal socket.
2. Removing the cover of the installation box or disassembling the body of the spotlight - the type of work is determined by the design of the lighting device.
3. Input of the network cable through a special coupling with a seal in the device body (pressurized lead-in) and fastening of the conductors in the terminal sockets. The connection of each core is made in accordance with the color marking and purpose of the core - phase, neutral, ground.

In the case of using separate light or motion sensors, the wires from the sensor and the manual light switch are connected into one phase contact group.

After fixing the wires in the terminal box, you must carefully replace the cover of the mounting box or the housing of the lighting fixture - the LED spotlight is ready to be installed at its workplace.

Electrical connection

Connecting the wire from the LED spotlight to a 220 V AC network must be done after de-energizing the installation site and turning off the supply voltage. To do this, you need to turn off the main circuit breaker in the control panel or a separate circuit breaker, if provided for by the network wiring diagram.

If there is no color marking of the AC cable, before turning off the machine, it is necessary to determine the phase conductor using a special indicator screwdriver. This measure is related to the requirement that all switches and sensors must be mounted in the phase conductor gap.

Place for connecting an LED spotlight

In order to connect a spotlight, you need to decide on the place where the spotlight will be connected and what area it will illuminate. Connecting an LED spotlight begins with inspecting the connection location and lighting area, drawing up a diagram of the proposed lighting locations, as well as calculating the convenience of connecting to power sources and placing supporting structures.

Devices of this type can be installed on the ceiling, walls or supports. The main condition for installation will be a smooth mounting surface. The installation height of the LED spotlight will directly depend on its size, power, and also the object of illumination. The maximum recommended installation height is 16 m. In this case, the installation angle can be easily changed depending on the lighting tasks.

LED spotlight installation

The spotlight is installed using supporting structures, after which the device is connected to the power line. The entire installation process will depend entirely on the type of floodlight you are using. It is the installation of the spotlight that will in the future have to ensure the operation of the entire system, as well as each of its elements separately. Installation of the structure is carried out with the obligatory disconnection of the device from the network.

It is worth considering that installation must be carried out taking into account subsequent management of the structure. To securely fix the spotlight on the support, it is necessary to secure the bracket as firmly as possible and securely tighten the mounting screws and bolts. In order to ensure the ability to adjust the lighting angle, it is necessary to loosen the side screws of the axial fastening of the bracket on the body, set the required lighting angle and fix the position of the device by tightening the bolts securely.

Connecting an LED spotlight

Next, you can proceed to the section on how to connect an LED floodlight. This device is connected via a terminal box, which is located on the rear side of the housing in a self-contained sealed compartment. To connect the spotlight to a 220V network, you need to open the lid of the box and remove the seal from it. Next, stretch the power cord and connect its ends to the appropriate contacts. Tighten the screws on the terminal and close the box. It is worth remembering to maintain complete tightness during assembly. The slightest ingress of water into the terminal box can damage the entire structure.

The LED floodlight must be installed by a qualified and experienced professional who is familiar with this type of equipment. In any case, the installation of such a seemingly simple device must be approached carefully and thoroughly. Only this approach will guarantee long-term and uninterrupted operation of the structure. You can learn more about connecting LED spotlights and the features that should be taken into account at:

LED products appeared on the market several years ago, becoming a real breakthrough in lighting technology. These versatile, durable and reliable devices are characterized by many other advantages, including high efficiency and versatility.

It's no surprise that people are wondering how to connect an LED floodlight. After all, the devices are used at administrative and industrial facilities, for decorative lighting of summer cottages, gardens and the interior of country houses.

Performing these steps requires a certain level of electrical knowledge. Professional installers do not recommend connecting LED spotlights yourself, as this can lead to problems and complete failure of the soffit. However, if you act carefully and take responsibility at every stage, the result will be positive.

Scope of use

The areas of application of these devices are extensive. They affect the domestic, industrial and commercial spheres of life. When using floodlights for decorative lighting of architectural structures, you should choose a design with a degree of protection against dust and moisture IP65 or higher. In this situation, the operability of the equipment is guaranteed in the temperature range from -45 to +50 degrees. Celsius, resistance to precipitation, including rain and snow. Floodlights are placed at elevated locations and have a service life of more than 50,000 hours.

SDO 5 devices can be used for lighting warehouses and production workshops, due to low energy consumption and low financial costs. The high cost of the products quickly pays off due to cost-effectiveness, since at such facilities they are operated almost around the clock.

Diode floodlights are used to illuminate various open areas with exhibition windows, football fields and other sports grounds. In this case, the choice of power and color temperature is important, which will allow you to avoid shadows cast by objects and accurately convey colors, emphasizing the advantages of the product (in the case of retail displays). The equipment is used to illuminate billboards, allowing you to correctly place accents.

You can often find LED spotlights in theater and cinema concert halls. With their help, effective and controllable lighting is organized.

One of the advantages that has led to the prevalence of LED floodlights all over the world is environmental safety. In case of failure, the device is disposed of as normal waste.

LED floodlight design

Most spotlights of this type is made on the basis of an aluminum body containing glass or plastic reflectors for scattering light or forming narrowly directed light beams. The presence of several inclined mirrors inside the housing or special panels (not necessarily glass) allows you to set the desired direction of the light flux.

The working part of the spotlight is called LED matrix. It consists of one or more semiconductors soldered onto a regular circuit board. Despite the fact that the matrix does not emit heat to the outside, it heats up from the inside. The duration of operation of the device depends on how well the heat removal is organized.

For these purposes, special radiators are used. During the heating process, the temperature across the substrate with minimal resistance is transferred to the radiator (the presence of thermal paste is required).

For stable and long-term operation, LEDs require a constant voltage with minimal fluctuations. Responsible for compliance with this requirement additional element– driver (power supply). This small part contains a transformer, diode bridge, capacitor and stabilizers. Can be supplemented with other electrical components.

Motion sensors are often connected to street floodlights, so they only work when necessary, when the sensor detects the approach of a person. The motion sensor is characterized, among which are sensitivity and range of action. The first characteristic determines whether the device will respond to the movement of a dog and other small creatures, and the second determines how far a person must be from the spotlight for the light to turn on.

Another innovation in the connection scheme for LED floodlights is an automatic switch. It reacts to the ambient light level and, depending on how dark it is in the room/area, turns on the lighting fixture at a certain power. For example, during the day in sunny weather the spotlight will not turn on at all.

Failure to comply with electrical safety rules when installing, connecting and operating lighting devices will lead to unpleasant and tragic consequences.

1. Regardless of whether you are installing the device to a 220 V network or installing a 12 V device powered by a battery, never wet your hands before work. Avoid handling electrical equipment if your hands are wet or sweaty. Never perform any operation on street lighting when it is damp and cloudy outside.
2. Be sure to disconnect the circuit from the power supply to avoid electric shock.
3. Measure the voltage in the network and make sure that its value does not exceed 220 V (small deviations are acceptable - 5-6%).
4. Avoid placing the spotlight close to low-power devices.

1. Try not to use near LED devices any chemicals.
2. If you notice interruptions in the operation of the LED spotlight, disconnect it from the power supply. Various drops can be associated with a malfunction of the matrix, a separate diode, or voltage surges in the network.
3. Despite the versatility and simplicity of LED products, consider a maintenance and care plan for the product.

Stages of work execution

Work on installing and connecting diode spotlights is divided into three stages: searching for an installation site, preparing tools and materials, and direct connection.

Location determination

Here you need to move “from the end”: determine the area that should be illuminated by the spotlight, and then select the location for its installation so that the luminous flux falls on the desired area. Ideally, you need to make a diagram or draw a sketch. Make sure there are power sources nearby or install wiring. It is important that the existing brackets are securely attached to the wall or selected object.

Spotlights can be attached to the ceiling, supports, walls, and the main condition is the presence of a smooth surface for installation. The installation height depends on the dimensions and power of the product, the illuminated area, etc. It is recommended to mount small floodlights to a maximum height of no more than 16 m. Remember that these are multifunctional devices that allow you to easily set a specific angle of inclination.

Equipment and materials for connecting to the electrical network

During the work process you will need:

• side cutters;
• a stationery knife or a special tool for stripping wires;
• soldering iron with all accessories;
• insulating tape;
• screwdriver.

Connecting an LED spotlight with and without grounding

Read the instructions carefully. If it does not indicate anything about polarity, then you can ignore it when connecting to the network. To connect the spotlight, use flexible copper or any other conductor that is resistant to high temperatures (up to 160 degrees Celsius). There is not always a need for grounding, so you can simply insulate the yellow-green wire well and hide it in the back of the device.

Connecting a device to a particular network depends on the modification. These can be devices operating from a 220 V AC network, or equipment operating from sources direct current at 24 V. V the latter case A regular household current rectifier can be used.

Before installation, inspect the body of the spotlight and make sure there are no visible mechanical damages. Free the terminal block by removing the cover to gain access to the terminals and ground connections. Unscrew the stuffing box and de-energize the room by turning off the power supply from the common distribution panel.

When replacing the spotlight with a new one, you need to throw away the old one, having first removed all the wires from it. It is advisable to select devices for which an identical mounting structure is suitable. Install the cover on an empty space - this element will protect the wires from water ingress.

Place the spotlight, attach the screws and bolts, remove the wires from the box and connect them to the required ones in accordance with the electrical diagram. Using a soldering iron, ensure secure fastening and good contact on the wires. Insulate, hide the connections inside the terminal box and replace the cover by tightening the bolts. Special latches can also be used for these purposes.

Tighten the screws on the floodlight to firmly attach it to the installation location. Apply power and make sure the light fixture is functioning.

Features of connecting an LED spotlight with a motion sensor

The process of connecting the spotlight via a motion sensor requires a slight adjustment to the instructions indicated above. The sequence looks like this:

1. Unfold the spotlight and find the terminal box. Remove the screws to gain access to the triple header with the terminals connected to the LEDs.
2. There are special holes in the device body through which you need to hang the wires. If this hole is sealed, then you will see a rubber seal with a nut. Route the wire and be sure to tighten this nut.
3. Connect "plus" to "plus". Typically, such wires are painted brown or red and are designated L - phase.
4. Connect "minus" with "minus". This is a neutral, which is designated by the letter N and is painted in cooler shades - light blue, black.
5. In almost all cases, grounding is required. Look for a striped wire (usually a mixture of yellow and green) labeled RE.

The motion sensor has at least two wires - “plus” and “minus”. In some cases it is equipped with grounding. Connect the negative cable directly to the spotlight, as it must always be connected to the circuit.

Essentially, you connect the device through a switch that operates automatically rather than manually when motion, heat, or sound is detected. For this reason, a positive value will be supplied to the spotlight only if the sensor is triggered. The desired spotlight terminal will be indicated Latin letter A.

If the sensor is built into the spotlight, then the latter will contain a terminal box with three wires and similar symbols.

Many touch elements support adjustment of basic parameters:

1. Sensitivity. If the percentage is too high false positives, then reduce this value.
2. Photosensitivity. A special photocell registers the illumination and, for example, will prevent the spotlight from turning on during the daytime.
3. Timer – allows you to set the time during which the device will operate after detecting movement, sound or a thermal object. Threshold values ​​vary. The minimum limit is a few seconds, the maximum – up to an hour.

As you can see, installing LED floodlights is as simple as possible. The main thing is to follow the rules and recommendations so as not to violate electrical and fire safety requirements.

The design of the devices is as simple as possible, and for their operation it is enough to connect three cables - negative, positive and grounding. Even with a motion sensor or photosensitive element, the installation process becomes slightly more complicated. LED floodlights are becoming a popular lighting equipment for households. Today, these lamps are used inside utility rooms, in courtyards, near personal plots and country houses. They are displacing classic incandescent lamps from the domestic sphere due to their combination of efficiency and environmental friendliness with high lighting efficiency. Due to the special internal structure It’s not always possible to connect an LED spotlight to the network correctly the first time alternating voltage

220 V. This article discusses how to connect a diode spotlight and ensure its safe operation.

How does an LED spotlight work?

Manufacturers typically house these devices in aluminum housings with a plastic or glass light diffuser. To transmit the light flux in a certain direction, a traditional system of mirror panels (can be plastic or metal) or inclined mirrors is used.

The source of the glow is an LED matrix, which is one or more semiconductor crystals lined up in a row, placed on the board. Many people know that LED lamps emit a negligible amount of heat to the outside. However, the heat entering the device can be more significant, so there is a risk of overheating of the matrix. This is especially true for LED spotlights, as they have increased power. That's why important point

The work of a diode lamp is to remove heat. For this purpose it is equipped with a radiator. Thermal energy is transferred to it through thermal paste connecting to the substrate.

The service life and quality of the glow of an LED spotlight largely depends on the stability of the power supply. To ensure this, the design includes a driver - this is an electronic device with capacitors, a diode bridge, zener diodes, a transformer and other components necessary to convert the input current to optimal operating parameters.

• street floodlights are often equipped with sound or motion sensors. They turn on automatically when someone passes nearby. This mode of operation saves more money than it may seem. In addition, it is convenient on farm sites and farmsteads, if you need to turn on the lights, but your hands are busy;
• Installing a photosensitive element in the control circuit allows you to automatically adjust the LED spotlight to the ambient light level.

In both cases, the sensors allow you to configure the response time to the turn-on signal and the operation timer. You can set a delay so that the lamp turns on 5 seconds after the clap, and then goes off exactly 30 seconds later.

How does the spotlight connect to the network?

The scheme for connecting the spotlight to a 220 V network is relatively simple, so the connection can be made even by a person with little experience in electrical installation.

First you need to get to the contacts of the device itself. To do this, you need to unscrew the 4 screws at the back of the device that secure the terminal box cover. Inside there is a triple block, the terminals of which are connected to the light element located inside the spotlight.

The device body has special holes for connecting wires. The sealed holes are closed with a rubber washer and a nut. The latter must be installed after laying the cable to prevent dirt and moisture from getting inside.

How to connect wires:

1. The positive contact is, accordingly, connected to the positive one. As a rule, it is designated by the letter “L” and has a brown or red color.
2. The negative contact is connected to the negative (neutral), marked with the symbol “N” with a cold color designation (blue, dark blue, black).
3. It is mandatory to connect the ground through the NE wire, which, according to international standards, is colored green and yellow with stripes.

If the spotlight has a motion sensor, then in the circuit it acts as a classic switch. The only difference is that the closing/opening takes place automatically under the control of the corresponding relay. The closing terminal, through which a plus is supplied to the spotlight after the sensor is triggered, is indicated by the symbol “A”.

Connecting an LED spotlight with three wires is a standard option that involves phase, neutral and ground. In cases where the switching sensor is built inside the spotlight housing along with the LED base, its contacts are output to the terminal box. In this case, it has 3-4 contacts, which are marked according to the same rules as described above.

When choosing a place to place an LED spotlight in a local area or utility area, you need to consider:

• distance from the socket or switch (if its use is intended);
• placement height. Spotlights shine very brightly and should be positioned no lower than head level;
• to extend its service life, the device must be protected from precipitation and mechanical impact;
• the device requires high-quality ventilation, so its installation location should not be a blind pocket or corner;
• To effectively illuminate the area in front of the lamp there should be no trees, buildings or obstructing structures.

As a rule, LED street lights do not have a socket, but a cable.. It must be laid in a cable channel or electrical installation corrugation. It is better to lay a cable with a power cable to remote poles. Installing an LED spotlight on a surface with any slope does not create any difficulties. First, a bracket is installed using dowel nails or screws, and then a lantern is attached to it and the required lighting angle is set.

LED floodlights are gaining popularity because they save huge amounts of energy. The installation of such devices should be entrusted to a professional, but if necessary, you can connect it yourself. Remember about important rules work with electrical equipment:

Connecting an LED spotlight

To connect the LED spotlight you will need a Phillips screwdriver, a sharp wire stripper, side cutters and a three-core round cable with a diameter of 7 mm. Remove the four screws on the back cover of the device where the terminal block is located. Unscrew the sealed gland (the gland nut with a rubber gland for the wires to exit) and pull out the gland. Pull the stripped wires through the sealed tap into the terminal block. Use a flat screwdriver to slightly unscrew the terminals located inside, then insert the wires into them: brown to ground (E), red to phase (L), blue to neutral (N). Tighten the terminals.

It is important to remember that the LED spotlight is sealed. There is a special rubber band around the entire perimeter of the terminal block cover for protection; when connecting the LED spotlight, it is important to inspect it for damage. The rubber gland should fit tightly around the connected cable. Assemble the terminal box and tighten the cover with screws.

Spotlight installation

The installation location of the spotlight can be on a pole, ceiling, walls, even on the floor, the main thing is a flat surface. You will need a bracket with three holes, which is secured to the support using fasteners.

To weaken the lighting angle, you need to slightly loosen the side screws of the spotlight, rotate the spotlight and tighten the screws. When installing, maintain a minimum distance of 25 cm from surrounding objects.

Floodlight with motion sensor

In the context of general energy savings, floodlights with motion sensors are gaining popularity among buyers. They turn on when there is movement in the field of view, helping to reduce electricity costs.

The main question that arises when installing such spotlights is the choice of the area that will be illuminated; its area depends on the installation height. With a standard height of 2.5 m, this is about 12 meters. Connecting a floodlight with a motion sensor requires drawing up special scheme, it identifies areas requiring lighting, mounting points for support brackets, and optimal ways to approach the network. Select a flat surface on which to install.

Exploitation

LED spotlights cannot be disassembled. Basic care for these devices consists of cleaning the housing and visually inspecting it for damage. If the spotlight starts to flicker, unplug it and replace it with a new one. They cannot be repaired.

Operate LED spotlights away from strong heat radiation and avoid installation locations with strong vibration. Do not use aggressive chemicals for cleaning. Abrasive powders and pastes can damage the body or glass of the device; liquid detergents should be used.
