My respect to the electrician Alexander, I am very pleased with the result - it looked so cool in the room with these lamps. I chose LED ones to have more light and not get too hot. We have a suspended ceiling made of plasterboard, we had to distribute the points, the contractor advised differently, not as I wanted at first. And sure enough, when it was ready, it became clear - it turned out great... beauty!!!

Installing LED lamps allows you to reduce electricity consumption by 10 times compared to a simple electric light bulb, and by a third - with any other fluorescent lamps. At the same time, such lighting devices do not heat up.

LED lighting devices can be used in different conditions. The quality of such lighting is significantly superior to incandescent lamps. LEDs are an ideal solution for decorating a house or apartment. Many of them support the option of dimming the light. It is especially needed in order to save energy with a large number of lamps.

The site selects private craftsmen who install lamps. These can be either built-in or surface-mounted lighting devices.

When I decided to renovate the hallway, one of the first questions that arose was the question of choosing the type of ceiling finish and which ones to install ceiling lamps. Having many years of experience When using a PVC stretch ceiling in the bathroom and living room, it didn’t take long to choose the type of ceiling. I decided to install a PVC stretch ceiling due to its many advantages compared to other types of ceiling finishing.

The ceiling lights took some thought. On the one hand, I wanted to install modern LED spotlights, and on the other hand I hung homemade kit DIY chandelier and sconce lamps. I liked them, and I didn’t want to part with either the chandelier or the sconce.

Ultimately, a compromise solution was found: the chandelier and sconces at the entrance to the hallway should be left hanging in their original places, and in the hallway corridor, where a single-lamp lamp hung on the wall, install recessed ones. suspended ceiling Spotlights.

Before installing a suspended ceiling, it is necessary to lay electrical wiring, and in order to lay the wires it is necessary to develop electrical diagram, based on the type and number of lamps, the type of light bulbs and their power.

Selecting the type of light bulb for a recessed ceiling light

Before purchasing a built-in suspended ceiling lamp, you need to select the type of light bulbs and determine the required number of them to ensure sufficient illumination of the room. Currently, four types of lamps are used for installation in recessed ceiling lamps: incandescent, halogen, compact (they are also called energy-saving lamps or daylight) and LED. Each type of light bulb has its own advantages and disadvantages; in addition, it affects the minimum distance between the installation horizon of a suspended ceiling and a fixed one, which is a determining factor in rooms with low ceilings.

Using the table below, you can easily do optimal choice type of lamps for suspended ceilings, based on your requirements and boundary conditions.

Table for selecting the type of light bulbs for recessed ceiling luminaires
Technical specifications	Lamp type
	Incandescent	Halogen	Energy saving	LED
Minimum distance between main and suspended ceilings*, cm	10-12	5-6	10-12	5-6
Supply voltage, V	220	12, 220	220	12, 220
Luminous flux*, Lm/W	10-15	15-20	50-70	80-120
Maximum power*, W	40	40	40	7
Color temperature, °K	2700	3000	2700, 3300, 4200, 5100, 6400	2700, 3300, 4200, 5100
Service life*, hour	1000	4000	8000	70000
Price	Very low	Low	Average	High

Technical parameters marked * may differ up or down depending on the design of the lamp and light bulb, the power of the light bulb, the manufacturer, and the type of suspended ceiling. For example, PVC stretch ceilings are afraid of heating above 60°C, and this limits the permissible power of light bulbs in recessed luminaires.

It should be noted that halogen lamps, designed for a supply voltage of 12 V and 220 V, are very sensitive to excess supply voltage and often burn out as a result. For 12 V halogen lamps, a step-down transformer or power supply (adapter) is required, for which you must remember, in case of installing a suspended ceiling without access to the interceiling space, to provide a special place on the wall.

You can obtain more detailed information about incandescent and halogen lamps, energy-saving lamps, and LED lamps by visiting the website pages specifically dedicated to them.

Calculation of power and number of lamps

The power of the lamps depends on the size of the room (area, height and shape), the color of the walls and furniture, the purpose of the room and the preferences of the owner. Some people like bright light, while others prefer warm, diffused light of low brightness.

It is almost impossible to accurately calculate the power and number of luminaires, taking into account all factors. For an estimated calculation, you can use the illumination data presented in the table, thanks to which, taking into account luminous flux, depending on the type of light bulb, you can determine how many and what power you need to install lamps in the room, depending on its type.

Table for calculating the power and number of lamps depending on the type of room
Type of room	Power required to illuminate 1m2 of room area depending on the type of lamp
	Incandescent	Halogen	Energy saving	LED
Children's	40	30	10	5
Kitchen	30	25	7	4
Living room, bathroom, toilet	25	20	6	3
Bedroom, hallway, corridor	20	15	5	2
Utility rooms	10	7	2	1

Let's look at an example of a calculation that I did for the hallway corridor. It was planned to install LED ceiling lights spotlights. The shape of the corridor is the letter T with areas of 2.8 m2 and 4.5 m2. The total area of ​​the corridor was 7.3 m2. Let's calculate the required power of the lamps 7.3 × 2 = 15.6 W. Since the ceiling height was 2.75 m and the walls were planned to be painted in creme brulee color, taking into account the complex shape of the corridor, the optimal solution would be to install four ceiling spotlights with LED lamps installed in them with a small reserve, with a power of 5.5 W, supply voltage 220 V with pin socket GU5.3. The pin plinth for suspended ceilings is good because it has small dimensions, which is important when the inter-ceiling space is small in height.

Before the renovation, there were paintings by artists on the walls in the corridor, which were planned to be left in their original places after the renovation was completed. Therefore, for undistorted color rendition, white light LED lamps with a color temperature of 4000 K were chosen. If you need warm light, then you should choose a lamp with a color temperature of 2700 K.

It should be noted that it is not always advisable to use recessed ceiling lamps in rooms as the only source of lighting. A much better result can be obtained by using additional wall lamps or table lamps in a work or rest area. In this case, the power of the lamps in the ceiling lamps can be reduced.

If you have local lighting lamps, it is quite possible to completely abandon the lamps built into the suspended ceiling, replacing them with LED strip ceiling lighting.

So, when solving the issue of lighting the premises of an apartment, there is room for creative imagination to unfold.

Selecting a wire for wiring spotlights

To lay the power supply wiring for four selected lamps with a total power of 22 W, any double-insulated electrical wire designed for wiring is suitable. A copper stranded double connecting wire, for example type PVA 2×0.75, is best suited. You don’t have to think about the cross-section of the wire cores, since the maximum current will not exceed 0.1 A.

When using 12 V halogen lamps in ceiling lamps, the wire cross-section must be calculated. One such 60 W light bulb consumes a current of 5 A. And if ten light bulbs are needed for lighting, then the current consumption will be 50 A.

Selection and installation of a recessed ceiling spotlight

The range of recessed ceiling lamps in any lighting store is huge, but they are all designed the same and differ only in the type of body finishing and additional decorations. Some models of recessed luminaires provide the ability to change the direction of the light flux within small limits.

Any recessed ceiling lamp consists of a body, which is a shaped profile ring with areas for attaching two springs with ears. Depending on the type and power of the light bulbs, the lamp housings come in different diameters and may not have them, like the lamp in the photo above, or they may have an electric socket installed, usually E14.

A special place is occupied by LED ceiling spotlights, in which the LEDs are installed directly in the housing on a printed circuit board.

The light bulb in such a lamp cannot be replaced, and if it fails, you will have to change the entire lamp or look for replacement LEDs. Such lamps are expensive.

For lamps without sockets, a spring in the form of a cut ring is used to secure the light bulb in the body.

The light bulb is inserted into the lamp body and is fixed due to the fact that the spring ring, unclenching, fits into a specially made groove in the body. This lamp is suitable for installing both halogen and LED bulbs. When replacing halogen bulbs with LED bulbs or vice versa, you must remember to check what supply voltage they are designed for.

To secure a ceiling spotlight in a suspended ceiling, regardless of its type, a hole is cut in a given location on the ceiling, slightly smaller than the outer diameter of the flange of the lamp body.

The ears of the springs are brought together by hand to such an extent that they pass into the hole in the ceiling. The ears are inserted into the ceiling hole and released. Leaning on the inner surface of the suspended ceiling, the lugs are pulled in until the flange stops against the lower surface of the suspended ceiling and thus fix the luminaire.

Such simple design Mounting the ceiling lamp allows you to hide the elements of its fastening and easily remove the lamp if necessary. Simply grab the base of the lamp and pull it down.

After installing the lamp body on the suspended ceiling, a wire is threaded through it and connected to the socket using a terminal block. The socket is placed on the base of the light bulb, the light bulb is inserted into the lamp body and secured with an expansion spring.

Electrical wiring diagram
for spotlights

Before installing a suspended ceiling, after choosing the type of light bulbs, calculating their power, the number of lamps and their installation points, an electrical wiring diagram is developed. When developing an electrical circuit, it is necessary to take into account the points and methods of connecting the wires to each other and to the lamps.

Since the wires to which it was previously connected were already coming out of the wall Wall Light, then it was decided to connect ceiling lights to these wires. It was planned to install a suspended stretch ceiling made of PVC, and the wires came out above the level of the stretch ceiling, and, therefore, there would be no access to the connection points of the wires after installing the ceiling. Therefore, it was decided to make all wire connections in the most reliable way, twisting followed by soldering with tin-lead solder. The soldering points were marked on the electrical diagram.

When choosing a place to install lamps and chandeliers in rooms where there is a TV or computer, you must not forget that the angle of incidence of the light beam equal to angle reflections. Taking into account this rule, lamps must be installed in places that exclude their reflection on the monitor screen, therefore, to select installation points for lamps, it is necessary to think about how the furniture will be arranged, in what place the TV or computer monitor will be installed.

When choosing light bulbs for a supply voltage of 220 V, installation of additional devices is not required. In the case of using light bulbs with a supply voltage of 12 V, it is necessary to provide space for installing transformers or adapters, taking into account their overall dimensions and possible access to them for Maintenance or repair.

Attention! Before connecting spotlights, to avoid damage electric shock, it is necessary to de-energize the electrical wiring. To do this, turn off the corresponding circuit breaker in the distribution panel and check the reliability of the disconnection using the phase indicator.

Electrical wiring installation
for connecting spotlights

After purchasing lamps, determining their installation locations, purchasing materials and equipment, you can begin installing electrical wiring.

Installation of electrical wiring for connecting lamps can be carried out at any stage of the renovation of the room, right up to the installation of suspended ceilings. But when repairing the walls in the corridor, it turned out that the light from the existing lamp was not enough. Therefore, the installation of electrical wiring had to be done first, and temporary sockets with energy-saving light bulbs were connected to the electrical wiring for lighting.

Before installing the wires, it is necessary to mark on the ceiling the installation locations of the lamps (circled in the photo) and the points where the wires are attached. To avoid sagging, the wires, depending on their rigidity, are fixed in increments of 40-50 cm.

To secure wires to the ceiling and walls, there are special dowel clamps (pictured on the left) and nail brackets (pictured on the right) of different sizes. To secure the wire with a dowel clamp on the wall, you need to drill a hole, put the dowel clamp on the wire and hammer the dowel into the hole. To secure a wire with a nail clip, you need to press the wire against the wall with it and hammer in the nail. Suitable for installation of wires and cables on wood, plastic, plaster.

Nail clips driven into a concrete plastered ceiling may fall out and remain on the PVC sheet. Therefore, this type of fastening was discarded. It turned out that I didn’t have dowel clamps at hand, so I used simple and reliable way securing the wires to the wall using a vinyl chloride tube clamp. A hole is drilled in the ceiling, a dowel is driven into it, and a self-tapping screw is screwed into the dowel through the hole made in the clamp. Since the weight of the wire is negligible, any self-tapping screw and dowel of the smallest standard size will do.

Making a wiring harness
ceiling spotlights

Since the electrical wiring for ceiling lamps after installing a stretch ceiling will be inaccessible for maintenance and repair, all wire connections in the interceiling space must be made extremely reliably. Connections are usually made using terminal blocks, such as Wago. But the most reliable type of connecting wires is soldering, and this is the method I used.

To minimize the amount of work at heights near the ceiling, a harness was made in advance, which will only need to be fixed to the ceiling and connected to household electrical wiring.

To determine the length of the harness wires and soldering points, using previously made markings on the ceiling, the distances between the wires for connection and the installation locations of the lamps were measured. The measurement results were immediately applied to the electrical circuit, which was also an electrical circuit.

The harness was made of stranded copper wire with double insulation (the core is entwined with silk thread and covered with polyvinyl chloride). For convenience, the wires were twisted together into a pigtail.

After removing the insulation from the wires, they were tinned with solder. In the second section of the corridor, the wires had to branch out. Therefore, the wires were twisted in pairs and soldered with solder. Please note that to increase the reliability of the insulation, the connection points of the wires were made offset relative to each other.

Before the connection, insulating tubes were put on the wires, which, after soldering was completed, were moved to the connection points. To prevent displacement of the insulating tubes, they were fixed on both sides with cambrics that fit tightly on the wires. Together with the displacement of the connection points, this insulation method guaranteed the reliability of the electrical wiring. Insulating the wires could also be done using ordinary insulating tape. To avoid confusion, the cambrics were marked.

When bending the cross beam, a small section of the wire harness passed below the level of the suspended ceiling. This section of electrical wiring ran under the plaster. To ensure reliable insulation, it was additionally covered with a polyvinyl chloride tube.

After the harness was secured to the ceiling, it was time to connect it to the apartment electrical wiring. To do this, the length of the conductors of the double wire coming out of the wall was trimmed with a shift. Since the wire was old, its insulation became rough and, in order not to damage the wires, it was removed thermally using a soldering iron. The cores were stripped and tinned with solder, and insulating tubes were put on them.

All that remains is to wind the ends of the bundle onto the cores of the network wire, solder it with solder and put on the insulating tubes. Thanks to the technology of shifting the wire connections, tubes are needed practically for human safety and aesthetics. Electrical wires cannot accidentally connect to each other.

The connection point is suspended from the ceiling using a clamp with a self-tapping screw. The electrical wiring for the spotlights has been completed.

Temporary electric sockets in places where spotlights will be installed are connected using terminal blocks, the light bulbs are screwed in and the repair can continue.

LED Ceiling Light Installation
on a PVC stretch ceiling

The technology for installing ceiling lamps, including LED ones, on any suspended ceiling of a rigid structure, for example, made of plasterboard, slatted ceiling or Armstrong, is described above. In the case of installing a spotlight on a suspended ceiling made of PVC or other plastic material you need to install additional fastening, otherwise the ceiling will sag under the weight of the lamps.

For these purposes, special fittings are produced. The photo shows a universal platform (ramp) for mounting spotlights. The platform has the shape of a cone, the surface of which consists of steps.

To adjust the diameter of the platform mounting hole to a specific type of ceiling lamp, use a sharp knife to cut off the excess steps from the cone.

The platform is attached to the main ceiling using perforated steel tape. A piece of tape of the required length is unrolled from the roll and cut with metal scissors.

There are two platforms with holes on the platform for fastening the tape with self-tapping screws. If you don’t have a short-length self-tapping screw, you can tighten a long one. The protruding part must be removed with side cutters.

The fittings for spotlights are screwed to the ceiling with self-tapping screws, led light bulbs connected to check. Everything works, you need to remove the light bulbs and you can start installing the stretch ceiling.

After the suspended ceiling is installed, the installation of lamps begins. To ensure that the PVC film does not tear and does not heat up too much, before making a hole in it for the lamp, a special plastic thermal insulating ring is glued to the place of its installation with special glue.

The film is cut out along the inner circumference of the ring with a sharp knife, the cartridge is removed and the platform is centered. The perforated tape is easily deformed, and the ceiling bends, so you can easily adjust the height and location of the platform in the horizontal plane.

Installing a ceiling light on a platform will ensure its reliable operation and will prevent the stretch ceiling from sagging and being damaged due to excessive heating when using halogen light bulbs.

In the photo you see the final result of the work on installing spotlights in a suspended ceiling.

During the renovation of the hallway, the question arose about the choice of ceiling lamps. I didn’t have to choose the type of ceiling, since I had experience working with suspended ceilings. A suspended ceiling made of PVC film was chosen. I had to think about which lamp to install on the ceiling. I wanted to have modern, beautiful lamps, and at the same time I didn’t want to part with the homemade chandelier and sconces hanging in the hallway.

The choice has been made. The chandelier and sconces remained hanging on the ceiling in the hallway, but for the corridor I decided to purchase spotlights, since there was a single-lamp hanging on the wall. Before installing the suspended ceiling, you should stretch the wires. To do this, you need to make a drawing of the electrical circuit, which includes the number of lamps, the type of light bulbs, and their power.

Selecting the type of light bulb for a recessed ceiling light

Today, 4 types of lamps are widely used:

• Incandescent;
• LED;
• Halogen;
• Compact (energy saving).

Each type has both positive and negative sides. In addition, when choosing lamps, you should take into account their parameters, such as the distance between the fixed and suspended ceiling. Using the table below you can find out the characteristics of the lamps and select the one needed for your ceiling.

Table for selecting the type of light bulbs for recessed ceiling luminaires
Technical specifications	Lamp type
	Incandescent	Halogen	Energy saving	LED
Minimum distance between main and suspended ceilings*, cm	10-12	5-6	10-12	5-6
Supply voltage, V	220	12, 220	220	12, 220
Luminous flux*, Lm/W	10-15	15-20	50-70	80-120
Maximum power*, W	40	40	40	7
Color temperature, °K	2700	3000	2700, 3300, 4200, 5100, 6400	2700, 3300, 4200, 5100
Service life*, hour	1000	4000	8000	70000
Price	Very low	Low	Average	High

Specifications may differ from the data in the table. It depends on the type of lamp, design, type of ceiling. For example, there are ceilings that are afraid of heating more than 60 degrees. This limits the choice of lamp.

Halogen lamps are afraid of voltage surges, so they often burn out. They are designed for both 12 V and 220 V. Lamps operating at 12 V require a step-down transformer and power supply. Therefore, when installing such lamps, do not forget about the space in the wall or ceiling for its installation.

Calculation of power and number of lamps

When choosing the power of the lamp, you should take into account the size of the room and the color of the furniture. You should select a lamp based on your taste. Using the table you can find out what power of lamps you will need. Calculations were made based on luminous flux values ​​and lamp type.

Table for calculating the power and number of lamps depending on the type of room
Type of room	Power required to illuminate 1m2 of room area depending on the type of lamp
	Incandescent	Halogen	Energy saving	LED
Children's	40	30	10	5
Kitchen	30	25	7	4
Living room, bathroom, toilet	25	20	6	3
Bedroom, hallway, corridor	20	15	5	2
Utility rooms	10	7	2	1

It was planned to install spotlights in the corridor. Here are the calculations that were made.

The corridor looks like the letter T. The area of ​​the plot is 4.5 m2, 2.8 m2. The total area is 7.3 m2. The required power of the lamps should be 15.6 W (7.3?2). The ceiling height in the room is 2.75 m. The plan was to paint the walls a creme brulee color. Since the corridor has a complex shape, it is necessary to install 4 lamps, the lamps of which will have a power of 5 W with a reserve. Power supply 220 V, pin socket GU5.3. This type of plinth is popular due to its small dimensions, which allows installation at a low ceiling height.

The walls of the corridor were decorated with paintings, which were planned to remain after the renovation. Based on this, I chose lamps white, whose color temperature is 4000 K. If you want to achieve warm light, lamps with a color temperature of 2700 K are suitable for you. Note that room lighting does not always have to consist of ceiling lights. It is better to reduce the power of the lamps and place a couple of wall lamps on the wall.

If there is local lighting, then the ceiling can be illuminated LED strip. Everything is limited by your imagination.

Selecting a wire for wiring spotlights

To power 4 lamps, any double-insulated wire will do. It is better to choose a copper double connecting wire that has many strands. For example, PVA 2*0.75. The cross section will not play a big role, since the current will not exceed 0.1 A. If used halogen lamps at 12 V, then you need to calculate the cross-section of the wires. One lamp with a power of 60 W consumes a current of 5 A.

Selection and installation of a recessed ceiling spotlight

You can find many lamps on store shelves. But they all have the same design and differ only appearance. Some models have the function of changing the direction of the light flow.

Since I need to illuminate the corridor, the most simple lamps with base chuck.

Each lamp has a body that looks like a figured ring, and platforms with fastenings for springs with ears. The type and power of the lamp determines its shape, as well as the presence or absence of a socket (usually E14).

A separate niche is occupied by lamps whose LEDs are placed on a printed circuit board.

If it fails, the light bulb cannot be replaced. You will have to either change the entire lamp or look for LEDs. And its price is not too low. Lamps that do not have a socket press the lamp using a spring shaped like a cut ring.

The lamp is inserted due to the fact that the ring expands and fits into the groove located in the housing. This lamp is suitable for both LED lamps, and halogen. Just don’t forget about the supply voltage that the lamps can withstand. To fix the lamp in the ceiling, it is necessary to make a hole at the location of the lamp, which will be slightly smaller than the outer diameter of the housing flange.

The ears of the springs must be spread to such an extent that they fit into the hole made. Then they can be released. Leaning on the ceiling, they press the lamp against the flange until it stops, which allows the lamp to be fixed.

After fixing the lamp in the ceiling, we thread the wire and connect the socket with the terminal block. The socket must be put on the socket, the lamp must be inserted into the lamp body, the spring must be released and secured.

Electrical wiring diagram for spotlights

Before installing the ceiling, you should pay attention to the choice of the type of lamps, the number of lamps, their location, and the choice of power. To do this, you need to develop an electrical circuit. During its development, the method of fastening the wires to each other and the points at which these wires are connected are taken into account.

Since there were wires coming out of the wall on which the lamp was located, they will be used for installation ceiling lamps. Since after installing the suspended ceiling there will be no access to the wires, they must be fastened in a reliable way. I settled on twisting and soldering with tin-lead solder. These points are marked on the diagram.

If you plan to place such lamps in a room where a computer or TV is located, you need to take into account that the angle of incidence of the beam on the surface is equal to the angle of reflection. Therefore, such lamps cannot be placed above equipment, as there will be glare from the monitor. Before planning the lamp, you need to consider the arrangement of furniture and equipment in the room.

If the lamps are powered by a voltage of 220 V, no additional equipment will be required, but if they need 12 V, then it should be taken into account that a place must be made for the power source of these lamps that will have easy access for maintenance.

Installation of electrical wiring for connecting spotlights

After purchasing all the necessary lamps and wires, you can begin to work.

Electrical wiring can be installed at any stage repair work. Even before installing a stretch ceiling. During the renovation of the walls, the light turned out to be dim. I had to connect temporary sockets into which energy-saving lamps were screwed.

Before installing the wires, select and mark the locations of the lamps. Marked with circles in the photo. To prevent wires from sagging, fasten them at intervals of 40 - 50 cm.

To secure the wires, you can use dowels - clamps (left photo) or nail clips (right), which have different size. If the installation will be done with a dowel - a clamp, drill a hole in the wall, put on the clamp and hammer the dowel into the wall. To secure the wire with a nail clip, press the wire against the wall and hammer in the nail. This installation is suitable for attaching wires to plaster, wood, and plastic.

Nail staples are bad because the nail can fall out and the wire will lie on the ceiling. This mount was immediately thrown aside. The Khomuts were not at home. Therefore, I used the most easy way, which is based on securing the wire to the wall with a clamp made of vinyl chloride tube. To do this, drill a hole in the ceiling and hammer in a dowel. We wrap the tube around the wire and screw it with any self-tapping screw.

Making a harness for wiring ceiling spotlights

After installing the ceiling, access to the wiring will be limited. Therefore, the connection of wires to each other must be done efficiently. Most often, the wires are connected using a terminal block, say “Wago”. However, the most reliable method is soldering. That's what I used.

To minimize work under the ceiling, the harness was made in advance. All that remains is to attach it to the ceiling and connect it to the main wiring. To find out the length of the wires, it is necessary to take measurements between the mounting points of the lamps. The measurement results were entered into the electrical circuit, which was an electrical installation.

The harness was made from stranded wires having double insulation. The core in such a wire is covered with polyvinyl chloride and entwined with thread. To make it convenient to carry out work, the wires were twisted into a pigtail.

The first step was to remove the insulation from the wires, which allowed the wires to be tinned with solder. The second section of the corridor involves branching wires, so they were twisted and soldered. To increase the reliability of the insulation, the soldering points are shifted relative to each other.

Tubes are placed at the soldering points to prevent short circuits. To prevent their movement along the wires, they should be secured with cambrics. The solder joints could be insulated using insulation tape. To avoid tangling the wires, the cambrics were marked with a marker. Part of the wire was located under the plaster. A polyvinyl chloride tube was placed in this place.

The tourniquet was attached to the ceiling. It's time to connect the wires to the main wiring. To do this, the wires coming out of the wall were trimmed with a shift. Since the wire is quite old, the cores are rough. To avoid damaging them, the insulation was removed thermally, namely with a soldering iron. The cores were protected, tinned, and then insulating tubes were put on.

Tubes are needed to protect a person from short circuits. The wires will not be able to touch one another on their own.

The place where the connection was made is secured to the ceiling with a clamp using a self-tapping screw. That's it, the wiring is complete.

The temporary sockets are connected with terminal blocks, the lamps are screwed in, and the room can be repaired.

Installation of an LED ceiling lamp on a PVC stretch ceiling

The technology described above is suitable for installing lamps on a rigid structure, such as drywall or slatted ceiling. If the lamp is installed directly on a PVC ceiling, it is necessary to provide mounting points for the lamps, otherwise the ceiling will sag under their weight.

For such purposes, special fittings are sold on the market. In the photo you can see the ramp, that is, the mount for the lamp. The platform is made in the form of a cone, on the surface of which there are steps.

In the photo you can see the final result of the ceiling repair, with ceiling lights installed in it.

When planning to decorate the ceiling at home or in the office, we often opt for a PVC stretch ceiling. And here it is important to decide in advance which lamps to install and how many of them will be needed. In this sense, LED spotlights are one of the most economical solutions today due to their high light output and durability.

First of all, even before installing the stretch ceiling, they lay the electrical wiring for future lighting. This is done according to a pre-developed scheme: the number of light bulbs, their location, rated power. However, this process has its own characteristics, subtleties and nuances, which will be discussed further.

Selecting the number and power of lamps

The number of LED lamps is selected based on the area and purpose of the room in order to obtain sufficient illumination, and taking into account the limitation on the PVC heating temperature - it should not exceed 60°C. These can be lamps with a supply voltage of 12 volts DC or 220 volts alternating current, with a power of up to 7 W each, for a light temperature from 2700 to 5100 K - from a warm, cozy home to a cold bluish glow.

The choice of lighting in an apartment is one of the most important from the point of view of room design. And as optimal option It’s quite possible to consider LED ceiling lights - easy to install, practical, efficient and presentable-looking. Despite not the most low cost, these lamps are now beginning to displace traditional incandescent lamps from the market. That is why we decided to consider this type of lighting fixtures in as much detail as possible.

LED lamps: design and features

Installation of LED lamps

It is possible to understand the advantages that a surface-mounted ceiling lamp has only after a thorough analysis of the features of its operation. So let's figure out how a classic LED ceiling lamp works?

• The basis of any LED lamp (whether built-in or surface-mounted) is a lamp, which is a set of several LEDs. The number and type of LEDs used are the main factors determining the power of the lamp, and as a result, the power of the lamp itself;

• The number of LEDs in one lamp can be different: some lamps use lamps with one LED, others use lamps with several dozen LED light elements;

• As a rule, all the LEDs of one lamp are included in a single circuit, which is connected to the control circuit via a power supply;

• Another mandatory element included in the design of a lamp based on LED lamps is the radiator. The thing is that during operation, an LED lamp generates heat, which requires mandatory removal.

Therefore, ceiling lamps, both overhead and built-in, are necessarily equipped with radiators of various types (see).

Note! High-quality heat transfer from the LED lamp to the radiator is ensured by special thermal paste. This thermal paste requires periodic replacement, since if the LED lamp overheats, it quickly fails.

Features of connecting LEDs in the lamp

As for the connection diagram for LEDs in an LED lamp, several options are possible. Therefore, if you do not plan to install a ready-made ceiling lamp purchased in a store, but are going to mount it yourself from the LEDs at your disposal - please read the information below carefully:

• Serial connection of LEDs - Quite common, but has a number of disadvantages. LEDs in many lamps are connected using this principle. industrial production;

• Parallel connection of LEDs is also possible. When connecting LED lamps in parallel, we connect current-limiting resistors in series to each lamp. The main task of these resistors is to protect LEDs from breakdown;

• Mixed connection of LEDs. When connecting LEDs using a mixed circuit, groups of several series-connected light elements (LED lamps) are connected in parallel to each other. This circuit is also widely used in LED lamps for home and office.

• The choice of the circuit according to which the lamp is assembled is determined by the advantages and disadvantages of a particular connection method.

Serial connection is the least costly (there is no need to use large number resistors), but it is also the most vulnerable. If one of the elements fails, the entire lamp stops working due to an open circuit.

In addition, for LED lamps with serial connection, another problem is relevant - if the LED does not just burn out, but breaks down, the circuit is not interrupted. In this case, the remaining LEDs included in the ceiling lamp quickly burn out due to operation under overload conditions.

This problem is not relevant for parallel connection - even if some of the LED elements fail, the LED lamps continue to operate, albeit not at full power. The proliferation of lamps with parallel connection is limited only by their high cost.

LED lights in your home

Advantages of LED ceiling lights

Modern lamps - surface-mounted, recessed and spotlights - are significantly different from all other lighting devices. Accordingly, compared to them, LED lamps have both advantages and disadvantages.
First, let’s analyze what benefits the installation of LED lamps will provide you.:

• Firstly, surface-mounted, wall-mounted and recessed luminaires are characterized by low energy consumption. An LED lamp consumes 10 times less electricity than an incandescent lamp and three times less than a fluorescent lamp providing the same level of illumination. Those. installing LED lamps gives you the opportunity to significantly reduce energy costs for lighting a house or apartment;

• Secondly, the LED lamps used in the luminaires have a rated life of about one hundred thousand hours (which roughly corresponds to 11 years of continuous operation). Consequently, it is necessary to change the lamps that come with ceiling lamps much less frequently;

• In addition, LED lamps do not contain mercury, which makes them absolutely safe from an environmental point of view.

In addition to all of the above, the advantages of overhead LED lamps include ease of installation. Unlike recessed lamps, which can only be installed during large-scale renovations (for example, when installing a slatted ceiling in a bathroom with your own hands), a surface-mounted lamp can be mounted on any ceiling in just a few minutes.

Disadvantages of LED lamps

However, in addition to the above list of advantages, overhead LED ceiling lamps have a number of disadvantages compared to other lighting devices:

• The first and main disadvantage of LED lamps is their high cost. The price of both home and office lamps (for example, Armstrong lamps) exceeds similar efficiency models with fluorescent lamps by 6-8 times;

Lamps with Cree LEDs are one of the best, but at the same time, one of the most expensive.

• The next drawback is the gradual “degradation” of lamps. Inexpensive models of LED lamps may lose brightness over time (after 3-5 years of intensive use). And if you consider that investments in LED lamps pay for themselves in an average of five years due to energy savings, then this drawback can be considered very significant;

Note! To partially insure against such situations, you should purchase overhead ceiling lights only if they have the appropriate certificate and warranty. As a rule, the warranty period declared by the manufacturer is 5 years.

Also, the disadvantages of LED lamps include the unpleasant spectrum of light they emit. In addition, the light from such lamps is quite narrowly directed, and if you use LED ceiling lamps - overhead or built into a suspended ceiling, then you may need to install more lighting points per unit area.

Analyzing the advantages and disadvantages of such lamps, we can observe almost parity: in some places LEDs are decisively superior to incandescent lamps, and in others they are significantly inferior to them. That is why you need to make a choice “for” or “against” very carefully.

Where to install the LED lamp

One of the most important factors when choosing an LED lamp is its placement in the apartment.

Let's try to figure out where we will install LED lamps?

• Bedroom. Here, an LED lamp is probably the least suitable. The rather harsh light from LED lamps will contrast with the entire atmosphere of this room, so it is better to avoid LEDs for the bedroom;

• Living room. Installing a surface-mounted LED lamp is quite possible - but only if the lamp fits into the overall design of the room. Therefore, LEDs are quite suitable for a high-tech living room, but for a classic living room we say a resounding “no!”

• Kitchen. Here the LED lamp can be used not as the main light, but as a directional backlight. For example, an overhead LED lamp can be installed above a sink or stove to provide bright light when cooking or washing dishes.

Note! Installing the lamp in close proximity to the stove burners (at a distance of 1 meter or less) is undesirable, since the heated air interferes with the heat transfer from the LED, and the lamp burns out quite quickly.

• Bathroom. Here, an LED lamp would also be quite appropriate (naturally, adjusted for the design of the room). For example, before you start making a slatted ceiling in the bathroom with your own hands, you can consider installing an overhead lamp and lead the wires into the space behind the ceiling in advance.

Also, overhead LED lamps - ceiling and wall - can be installed in outbuildings: garages, workshop sheds. External lighting of a private house can also be organized using LED lights and spotlights.

Installation of LED lamps

Required components

In order for the overhead LED lamp to work as efficiently as possible, when connecting, it is necessary to check the presence and functionality of a number of components.

In some models they are built into the lamp body, while in others they require separate installation:

• Radiator – we talked about its necessity above. Even if we mount an overhead lamp on a suspended or slatted ceiling, the radiator must provide effective heat dissipation;

• The power supply is a very important element that ensures the effective lighting of the lamp. Using low-quality power supplies can cause the lamp to flicker and create a “strobe effect.”

Power supplies use electronic and induction type transformers. The first ones are smaller and lighter (which is important for hidden installation), but are prone to breakage. Unlike electronic ones, induction transformers for LED lamps are more reliable and cheaper, but they are larger in size and weight.

As a result, both the radiator and the power supply must be selected based on where the lamp is connected.

Features of installing lamps on the ceiling

Overhead ceiling lights based on LEDs are most often produced in housings equipped with everything necessary for mounting. As a rule, a lamp of this type is quite easily mounted on the ceiling of the most different materials using simple fasteners - turboprops or dowels with metal or plastic sleeves (see).

Depending on the specific model, installation of overhead lamps from different manufacturers may vary.

In general, the installation process looks like this::

• At a selected location in the immediate vicinity of the lighting wire output, drill holes for the mounting plate (this process can be seen in detail in the video instructions);

• Holes for fastening must be made in a solid base. If the hole for the mounting plate falls into a void (the hammer drill typically “falls through” without encountering resistance), it is advisable to re-drill the hole slightly to the side;

Pay attention! When making holes for attaching the mounting plate, you must be very careful not to damage the wiring with the hammer drill.

• We fix the mounting plate with dowels;

• If the lamp is not mounted on a solid base, then it is necessary to first provide a fastening for the lamp. For example, before installing a slatted ceiling in a bathroom, the video instructions recommend securing bars to the ceiling, into which the mounting strip of the lamp is then attached.

• Having turned off the electricity at the meter or RCD (residual current device), we connect the contacts of the lamp to the electrical wiring. Most industrial LED lamps are equipped with terminal blocks for this purpose, making connection easier (see);

• We put the body of the connected lamp onto the eyes of the mounting plate and fix it with screws;

Advice! Very often in such situations, a long screwdriver with a blade made of a magnetic alloy helps: with its help you can fix fairly small screws in hard-to-reach fasteners.

• We put the transparent parts (cap or protective glass) on the fixed body of the lamp and check its functionality.

Summarizing all of the above, we can state: due to their characteristics, LED ceiling lamps will great solution for lighting a number of rooms in a house or apartment. And if you select the optimal model and install it correctly, then you are guaranteed bright and economical lighting for many years!
