level of complexity of the upcoming installation;
installation method cable lines and their length;
number of lighting fixtures and their total power;
urgency of task completion;
cross-section of each cable;
terrain.

The exact price for services in each individual case must be agreed with the master (or team) on an individual basis.

installation of mortgages and lighting fixtures

assembling the circuit and connecting lighting automation

In this case, the connection itself can be made in manual mode, when everything starts and turns off manually through one single switch, or automatically from light sensors.

But it is best to apply more universal option with the implementation of both methods in one panel room. Let's look at it in more detail.

Materials

Before starting work, you will need to purchase the following materials:

For lighting with a consumption of no more than 16A, this section is usually sufficient. But everything may depend on the length of the area and the power of the lamps.

If you are not limited financially, then you can choose an armored cable. In this case, you will not have to use HDPE pipes.

However, cutting it apart both in the panel room and when connecting lamps will not be easy. Therefore, most people use the usual brand VVGnG 3*1.5mm2.

Laying cables underground

Work begins with preparing the trenches. Draw up a layout of all the lamps on your site in advance.

Then, from the point where the cable exits the panel board RShch-0.4 kV, dig a trench 70 cm deep along all these points.

Next, pour a sand cushion 10-15 cm high to the bottom.

HDPE pipes are laid on top of it. In the end, you should end up with a pie that looks something like this.

Each pipe must have an outlet where the street lamp is installed. That is, they brought it to the first closest one, made a rise above ground level and cut it off.

Then from here they laid the second, third, etc. in the same way. Thus, in the future you will have the so-called parallel circuit connection of street lamps.

At some points there may be 3 or 4 pipe exits to the surface. It all depends on the lighting scheme and the placement of garden lights.

They can be very useful in the garden.

After completely laying the pipes, tighten the cable into them with a cable and leave some reserve (about 30-40 cm) in each light point at the exit from the pipe.

Cut the cable in these places and pull it to the next lamp.

If you have an extensive lighting system and several lines are laid, then each of the cables should be signed in advance.

When all the wires are laid, cover the trench with earth.

It is advisable to lay a warning tape at a depth of 30 cm from the surface.

It is inexpensive, but in the future, when you want to redevelop or lay additional communications on the site, this tape will protect your cable from accidental damage.

Installation of a street lamp

Now you can begin installing the mortgage for installing the lamps.

You make formwork with reinforcing mesh in the places where HDPE pipes exit. The size of the formwork depends on the thrust of the lamp post.

For good stability of the lamp post, the foundation must be buried at least 30 cm.

The cross-sectional diagram of laying wires and installing the mortgage is as follows:

After that, fill everything with the solution and let it sit and harden, dismantle everything unnecessary.

There are garden lamps with separate bottom cabinet, built in at ground level. They do not require any formwork for the thrust bearing.

It is enough to fill the bottom layer with gravel to ensure drainage of rainwater.

Next, secure the lower disk to a small layer of cement mortar.

At the same time, be sure to control building level installation horizon.

There is also no need to fill the solution inside such a cabinet. This is where all the wiring and wiring is done.

There is another simple option for installing a mortgage. Take a round flange along the diameter of the base of the lamp post.

The fittings are welded to it.

A hole is made in the ground to the appropriate depth using a hand-held garden drill, and the whole thing is filled with concrete.

The rigidity of this structure is even better than that of simply concreted formwork. In addition, all mounting pins will already be brought out.

When concrete base done, pass the cable through the bottom of the lamp post, and secure the base itself to the mortgage.

To do this, apply it to the concrete substrate and mark the attachment points for the anchors.

Use a hammer drill to drill holes of the required depth.

Insert and hammer a dowel into them.

Then firmly pull the base of the lantern to the concrete platform.

Next, you need to connect and connect all the cable cores. You strip the ends of the wires and put them into the junction box.

The connection can be made in any convenient way.

The simplest is the use of Vago terminal blocks.

The most important thing is to reliably insulate and seal this place. This can be done using a special electrical insulating compound.

After complete sealing, place the poured junction box in the base and finally install the street lamp.

There are models of lamps in which all wires are connected directly to a special contact block located inside the column.

Everything will depend on the type and type of street lamps. And they have a very rich variety, there is plenty to choose from.

You do all these connection operations with all the other lamps in your suburban area.

Assembling and connecting a street lighting circuit

We proceed to the installation and connection of all switching equipment to control the lighting in the panel.

The general diagram for connecting and controlling street lighting from a photo relay using a starter will look like this:

Let's take a closer look at how it works and is assembled “live” with our own hands.

In order to provide two modes of lighting operation - manual and automatic, use a three-position switch.

In the first position, through a regular one-keypad, you can manually turn on and off the street lighting whenever you want.

This will also come in handy if the automation suddenly breaks down or malfunctions.

The second position is the mode automatic control from a remote light sensor and twilight relay.

In position "0" the lighting is completely turned off.

On the DIN rail, place all the necessary automation in order in one row:

3-position switch or as it is also called a transfer switch

twilight relay

modular starter

machine guns

First of all, connect the power phase. Start it from a separate differential switch in the panel, first to the three-position switch (contact No. 1).

And then to the twilight relay (lower contact L) and starter input contacts No. 2 and No. 4.

If the power of the lamps is small and the total current does not exceed 16A, then the entire connection can be made with jumpers as in the figures above.

If you have powerful lights, such as DNAT, or the entire perimeter is hung with spotlights, then the starter should be powered only directly from the machine without any jumpers.

Connect the output from the starter to the upper terminals of the machines, to which cables laid in the ground to the lamps will be directly connected.

After connecting the supply phase, connect the zeros. One for terminal N of the twilight relay.

And the other one to the starter coil A2.

So as not to constantly climb into the closet when manual control, on a wall convenient for you, next to the switchboard, mount an ordinary single-key switch.

Connect a two-core cable VVGnG 2*1.5mm2 to it.

Place one wire of the cable on a three-position switch (terminal No. 2).

And you put the second one on the winding of the modular contactor A2.

Otherwise, this will all lead to incorrect operation and false positives. Stretch a VVGnG 2*1.5 cable from the panel to the sensor and connect it to its contacts.

Connect the other end from the photosensor cable to the twilight relay (contacts No. 2 and No. 4).

When the relay is triggered from outside, the twilight relay in the panel will close its upper contacts No. 1 and No. 3. Therefore, these terminals also need to be supplied with a phase from a three-position switch from terminal No. 4.

After the twilight relay, it goes to the starter coil A1.

As a result, we get the following automation operation scheme:

The 3-position switch is in position II. It gets dark outside, and therefore at a certain moment the photo relay is triggered.

Closing its contacts activates the twilight relay and the phase through it enters the winding of the modular contactor. The zero on the winding is constantly on duty.

As soon as a phase appears on it, the starter retracts and supplies voltage to the upper terminals of the lighting circuit breakers. Street lights and lanterns come on.

At dawn, the photo relay opens its contact, forcing its “twilight brother” in the panel to break the phase. The contactor falls away and the light turns off.

Do you want to turn off all automation? Simply flip the input switch to position I.

Lighting devices today are used not only inside the house, but also outside. This allows you to illuminate passages, create optimal conditions movement of people at night, etc.

Today, LED street lighting is increasingly being used for such purposes. This allows you to get very quality lighting, which at the same time consumes slightly less electricity.

Mounting methods

Street lamps are types of lighting devices that are designed to work in the external environment. Today you can find many types of such products on the market.

They all differ in installation method, among which there are 2 main options:

Installation using additional supports. This option can be found both on a city street and in a small park.
Fixation to a wall or other rigid frame. Very often used for illuminating exits, etc.

It should be understood that the installation method often depends on the purpose of the lamp and its design.

Connecting lamps

The installation process of such systems can be divided into several successive stages:

First of all, the wiring is laid from the source of electricity to the future location of the lamp. This can be done by air or by running a cable underground.
On at this stage The lamp is connected to the current source. This is done quite simply, since often only two conductors come out of the body of this design.
Accordingly, they should be connected to electricity. For such purposes, special distribution boxes, in which several clamps are located. The cables are fixed according to the diagram of your lamp. In this case, they should be fixed properly so that the wire jumps out of the clamp.
The final step is to attach the lamp to the frame. This is done differently depending on the shape of the product.

Please note that the lamp can be connected either directly to the source or through a switch or special photoresistors that will turn it on during the dark period of the day.

This scheme is quite simple, since it involves an intermediate link that is mounted between the current supply cables and the lamp. If you are not sure that you will do this correctly, then it is advisable to entrust it to an experienced electrician or carefully watch this video:

Installing street lamps in the area adjacent to the house has not only aesthetic, but also practical reasons. Arranging lighting to improve safety requires the involvement of professionals. Especially if high-altitude work is required.

Of course, if we are talking about building a street lamp for or garden path, then try to do everything yourself - this way you will save a lot of money. But to implement a large-scale street lighting project, it is better to use the help of specialists, for example, employees of the company svet-mir.ru, since you will have to deal with complex circuits.

We also advise you not to skimp on lighting fixtures. Wind, rain, snow and others natural factors mercilessly affect the entire yard infrastructure. High-quality lamps last longer and are more distinguishable beautiful design. Outdoor lighting fixtures (speaking in simple words– street lamps) have an index indicating the degree of their security. For example, IP44 means that these lamps can only be installed under a canopy, and the IP65 index means they can be installed outdoors.

Installation of street lamps must be carried out taking into account safety standards and manufacturer’s recommendations.

Types of street lighting:

floor-mounted, when the lamps are located close to the ground or in the channel of a surface drainage system;
high-rise - on poles from one to seven meters high; lamps can also be attached to the eaves of buildings or structures.

Prepare the bases for the lamp/s. Install pedestals, posts or pillars. If necessary, strengthen the foundation. This will provide good stability and prevent distortion under impact. strong wind. And to make the structure look nice, plant it under it.

Disassemble the lamp body in accordance with the attached instructions. The housing, protected from moisture, may contain plugs. Some manufacturers make lamp housings with snaps. The connected cable must be de-energized. At home, you can check the power supply of the cable using a regular indicator screwdriver. Additionally, take care that it is impossible to supply electricity while the work is being performed (so that no one accidentally or mistakenly turns on the network).

Using fasteners, which are usually included in the kit, secure the lamp body, connect the contacts to the socket and screw in the lighting lamp. When the installation of street lighting is almost complete, check that the connections are correct and begin testing the functionality of the lighting system. When assembling the case, pay attention to the correct installation of the plugs.

If necessary, you can perform additional waterproofing of the cable entry/exit points using silicone sealant.

Depending on the luminaire model, the contacts may already be connected. Therefore, during the installation process, it is enough to screw in the lamp and connect the lamp through a waterproof terminal block. Modern expensive models of outdoor lighting devices can be equipped with a motion sensor or a light sensor (photocell), which saves energy.

For several centuries, various lighting devices have been used for outdoor lighting of various areas and objects. In addition, with their help, experts try to give the landscape a special sophistication. Therefore, the issue of proper installation of street lighting becomes more and more relevant every year.

Proper organization of installation

The first step is to develop a street lighting project. It needs to take into account:

terrain;
level of required illumination of the territory;
length of the external lighting line;
total power of installed electrical equipment;
select the optimal cable cross-section;
the number of installed lighting devices and their design;
systems for its protection and control.

Variety of light source options

Recently, for the installation of outdoor lighting, they are increasingly using LED lamps. They visually resemble ordinary incandescent lamps. But it allows you to significantly save energy consumption. In addition, they are able to provide the necessary illumination of the territory for quite a long time. long term. Since they have fairly good resistance to high humidity and fluctuations temperature regime environment.

But sometimes other light sources are used for electric lighting of certain objects, for example, fluorescent or incandescent.

Variety of supports

Various structures are traditionally used as supports.

Support pillars. Traditionally they are made of reinforced concrete, various rolled metal or wood.
Aerial metal cable. It is stretched between poles over sidewalks or highways.
Power line supports.

Types of street lighting

Recently, landscape designers have increasingly been directly involved in its organization. They began to roughly divide it into two types:

Basics. Ensuring the safety of the movement of people and vehicles in dark time days. Traditionally it is placed along pedestrian paths on the streets, squares, parks.
Decorative. Greatly attractive various objects. For example, architectural monuments. For this purpose, traditionally, as a rule, the installation of LED street lighting floodlights of various designs is carried out.

Taking into account this division, the type of lighting device and its power are selected. After all, the amount of light they emit must be sufficient for the safe movement of pedestrians. But at the same time, do not blind drivers of passing vehicles.

Based on this, it is also necessary to determine optimal height location of street lighting fixtures.

It is necessary to work out a system for delivering electricity to lighting devices. Traditionally it is carried out by air or laying cables in the ground.

Classification of lighting standards

The brightness of street lamps is determined based on current building regulations. It is selected in such a way that the emitted light allows pedestrians to move freely around the area at night, but does not interfere with drivers of moving vehicles.

When installing street lighting, it is necessary to take into account not only the brightness of the lighting fixtures, but also their location.

After all, they are also mounted on the facades of buildings. This makes it possible to highlight house numbers or other advertising and information objects.

Control system

Proper installation of street lighting allows you to provide several ways to control it:

Manually. The dispatcher turns it on and off at a certain time.
Automatically. Lights are turned on or off using special sensors. It emits a signal when a preset light level is reached.

Features of equipment installation

underground;
by air.

Underground cable laying

Electrical cables must be laid in the ground only using special plastic or reinforced concrete trays or protective covers. To do this, a trench with a depth of at least 40 cm is dug.

Tip: If you want to lay the cable only in a protective casing, then experts recommend laying any plastic or metal mesh directly above it. When they start accidentally digging in the area where the electric highway is being laid, they will certainly come across such protection.

Aerial cable routing

In this option, you must first install the support pillars. And the supporting cable is already pulled over them. And the electrical cables are directly fixed to it using special clamps.

Smart sequence

Installation of street lighting begins with the development of an appropriate project. It calculates the required level of illumination of the area. Based on this parameter, lighting fixtures are selected. Defined by:
