Types of spotlights

All existing varieties of spotlights are divided into groups depending on the installation method, lighting control and functionality.

External or, as they are also called, overhead spotlights are used to install frameless bases:

• concrete ceiling;
• brickwork.

Such devices consist of a special mounting platform and a housing with a diffuser. In this case, a mounting plate with a smaller diameter than the housing is used. The body is fixed to the mounting platform using side screws.

Embedded models need a frame base:

• drywall constructions;
• walls and ceilings made of panels or slats;
• stretch ceiling;
• furniture partitions;
• niches in the walls.

An alternative option is to install appliances in the floor, pool, bar counters or on the stairs.

Advice! If it is decided to install massive lighting devices in the room, it is recommended to install additional mounting strips.

Types of ceiling lights

If we consider the types of ceiling lights, then it should be borne in mind that they are conventionally divided into the following types:

• superficial;
  
  
• rotary;
  
  
• suspended;
  
  
• invoices;
  
  
• embedded;
  
  
• point.
  
  

Lighting devices may also differ in the emitted light:

Ceiling models are great for rooms with small ceilings. Such chandeliers are in the shape of a plate. Models can have a large number of segments or act as a single design.

Important! Plafonds can be made of glass, plastic, crystal.

Types of LED strips

There are a large number of varieties of LED strips, they differ from each other according to a number of criteria. If we consider by the method of installation, then we can distinguish 2 types: DIP and SMD. If surface mount (SMD) is used, then this means that the LEDs and resistors are soldered to the board at the very top. DIP assumes that the LEDs are inside a special housing, of which there are 2 outputs on each side.

Thus, SMD LED strip looks like a flat strip, and SMD looks like a chain of small cylinders. After these abbreviations, the manufacturer indicates 4 digits, which indicate the size of the soldered LED chips. For example, if you purchase led strip SMD 5630, that means the chip size is 5.6mm by 3mm.

Since there are a large number of types of ceiling chandeliers, it is necessary to understand how to choose them correctly. During the acquisition process, it is recommended to adhere to the following recommendations:

• in rooms without windows, yellow lamps must be used;
• for work in the studio you should not use fluorescent devices;

Fixture device

The main components of the fixtures are:

• Electric lamp.
• Cartridge.
• Lighting fittings.
• Wiring.

Luminaires can work with different types of lamps. The most commonly used light bulbs are incandescent, LED and fluorescent. They may have different type base for connection to the cartridge. In luminaires that are used indoors, the E14 and E27 base formats are most often used. However, there are at least 10 more common options for spline and point connection lamps. A cartridge is used to fix the light bulbs. It, in turn, is fixed in the lighting fixture, which acts as a diffuser that directs the light flux to the required lighting area.

What are the lamps

There are several popular variations of lamps:

• Chandeliers.
• Floor lamps.
• Nightlights.
• Searchlights.
• Point.
• Busbars.
• Desktop.
• Office.

These are ceiling lights that are used to illuminate residential areas. They can be directly fixed on the ceiling, which is typical with a small distance to the floor. In the event that the distance to the floor is large, then the chandelier is hung with a cord or chain. Thanks to this, it is located lower, and the light of its lamps is distributed more efficiently. Lamps in chandeliers can be placed in different directions. Most often they are twisted upside down. In this case, the emitted light is effectively directed towards the floor. As a result, the room is illuminated evenly. In the case when certain types of lamps shine into the ceiling, shadows form. For this reason, when choosing light bulbs for a chandelier, you need to look at their design features.

Chandeliers completely illuminate the room. They are represented by a variety of design options, and abound in the largest number of fashionable interior solutions. Chandeliers can be equipped with inexpensive light bulbs with a standard base, the installation and replacement of which does not cause any difficulties.

Despite many advantages, such devices are not without disadvantages. First of all, they require a complex connection. Electrical wiring for their power supply is laid covertly. In the event that stretch or suspended ceilings are used, this is not so difficult. For plaster ceilings, the cable is pulled through a special channel in the floor slab, which implies fuss. In addition, chandeliers are difficult to clean from dust. Such lighting highly susceptible to mechanical damage. For this reason, chandeliers are not the best solution for children's rooms, where they can be broken during games.

Sconce

These are wall lamps that provide diffused lighting. Usually their shades are made of frosted plastic or glass. Sconces can provide various ways to turn on the lamps. Sometimes an ordinary wall is used, located on convenient location, near front door. In the vast majority of cases, the sconce has a switch in its own housing. To activate it, you need to pull the cord coming out of the lamp. Shutdown occurs in the same way. The variant with a cord is most often used for bedside sconces, and those that are located around the perimeter of mirrors.

Usually sconces create background illumination of various decorative elements. With their help, you can implement techniques for visually dividing space into zones. Sconce is used as additional source Sveta. Usually they are designed to install only weak lamps. Higher power bulbs get very hot. This leads to meltdown plastic parts sconces, which are present in almost all devices of this type.

floor lamps

Unlike previous varieties, these lamps are portable. They are installed directly on the floor. A tripod can be used as a stand, which provides the greatest stability, or one leg with a heavy platform at the base. There are varieties of floor lamps, which provide a small area that acts as a table. Such lighting fixtures can be placed near the sofa in the guest room or near the office chair. Usually, the floor lamp is turned on by a stationary button mounted on its body, or by a switch on the wire coming from the outlet. A floor lamp provides rooms with soft light, which is good for reading. Due to the high height of the floor lamp, sitting under it, the light falls from top to bottom at a special angle for good illumination of books and newspapers.

A floor lamp is a mobile lighting equipment that can be moved and installed in the part of the room where it is needed. Floor lamps are located close, so weaker bulbs can be used to equip them. As a result, energy costs are reduced. Floor lamps are available in different styles, which allows you to choose an option for any interior.

Floor lamps illuminate small space, so they can only be used indoors as a source of additional light. Since this is a portable device, the appropriate electrical wiring noticeably. Since the floor lamp is on the floor, if it topples over, it can cause damage to the bulb. If an incandescent lamp is used, it will undoubtedly stop working.

Nightlights

These are table lamps that direct light towards the ceiling or walls of a room. It diffuses well without creating blinding rays. Nightlights are usually equipped with weak lamps. The ceiling covering them is painted yellow, green, white or other soft color. Due to this, the transmitted light acquires a similar shade and does not blind the eyes at all. Typically, nightlights are used for installation in children's rooms. Externally, such devices can be made in the form of animal figures or cartoon characters. Nightlights create a duty light in the premises. They are easy to transport, compact and easy to connect.

Searchlights

These devices have high power and focus the light with a directional beam, therefore they are not used in residential premises. Similar equipment can be found in factories. The peculiarity of the spotlights allows for effective illumination of the required areas, which are located at a great distance from them. The spotlight can be mounted on high ceilings. It is more resistant to mechanical damage than other types of luminaires used for interior spaces. Spotlights create a directional light that can be shifted to different angles.

Point

These luminaires are designed to be built into a pendant or stretch ceiling. Usually, they are structurally designed for weak light scattering and direct their flow to a limited area of ​​\u200b\u200bthe floor. Each spotlight is equipped with a small light bulb, which, due to its small size, does not shine too brightly. There is no reflector in the design of spotlights, so a special type of lamp is used for them. On sale there are bulbs for spotlights that can be connected to a 220V network, as well as 12V. The latter requires a power supply.

Busbars

These are modern lighting fixtures that are usually used to illuminate living spaces made in special styles, such as high-tech or loft. They are a rail mounted on the ceiling. A swivel lamp slides along it, providing for the possibility of adjustment to direct the light to the desired area.

Desktop

Such a lamp combines the design features of a wall lamp and a night lamp. It is placed on the table and creates a diffused or directional light, which makes it convenient for meticulous work or reading. To turn on the lamp, a switch on its body or wire can be used. It is customary to install such lamps on written and computer desks. They can also be used in workshops to illuminate the working space of a seamstress, jeweler and other professionals.

Office

These are ceiling lights, which are usually equipped with fluorescent or LED lamps. They are used for installation in offices and industrial premises as the main source of light. They have a large reflective area and are equipped with several lamps at once, due to which they create a bright backlight. In terms of installation complexity, they are absolutely equal to chandeliers. The design of office lamps does not allow their use in residential premises.

Criteria for choosing fixtures

When choosing fixtures, you should pay attention to the type of light bulbs that you can put on them. This consumable significantly different in cost. The most affordable are spotlights, as well as those with an E14 or E27 base, so in most cases it is better to focus on lamps that are compatible with them. Also, in the instructions for the lamp, you need to find out information about the maximum power of the lamps that can be used in it. This is especially relevant information when using incandescent bulbs, which get very hot during operation. It should be borne in mind that many lamps have little space. This will not allow them to put large light bulbs with a large luminous flux.

Luminaires are devices that distribute artificial light in residential premises, offices and on the street. With their help, you can visually enlarge the space, create a romantic or solemn atmosphere, focus on interior details (mirrors, paintings).

How they work

The lamp consists of a lamp and auxiliary elements that drive the mechanism: a starter and a throttle.

• Starter - neon lamp with two bimetallic electrodes. Voltage is applied to the lamp, a discharge is formed in it, after which the starter elements are closed. A strong current flows between the lamp bulb and the starter electrodes.

Then the electrodes open the system, the voltage increases sharply through the inductor. Under the influence of voltage, the gas gap in the light bulb breaks through, and it lights up.

• The throttle is connected to the lamp in series, so the voltage is divided into both elements, the starter is connected in parallel, so there is not enough voltage to re-close the starter electrodes.

The inductor limits the current after turning on the device, maintains stable operation of the lamp.

Luminaire characteristics

1. Luminous flux - the power of light radiation, which is perceived by a person as visible light. The unit of measurement is lumens.
2. The intensity of light is the ratio of the luminous flux that propagates inside a solid angle to this angle. The value is measured in candela.
3. Luminous efficiency - the ratio of the luminous flux to the electrical power used by it. The unit of measure is lumens per watt.
4. Illumination is a quantity that determines how much light flux falls on a unit area of ​​the illuminated surface. Measured in lux.
5. Color temperature is a value that indicates the intensity (spectrum) of radiation. The unit of measure is kelvin.
6. The color rendering index is characterized by the naturalness and correctness of the image transmission.
7. Luminosity is the ratio of the luminous flux emanating from the considered small area of ​​​​the surface to the area on which the light is emitted. It is measured in watts per m2.

The standard kit of the luminaire includes the body of the device, the driver and the model with the lamp. Among additional accessories: cartridges, electromagnetic ballasts, electronic transformers, starters, lampholders, chokes.

How to choose a lamp

• Decide for what purpose you need a lamp. Consider the size of the room and safety precautions. In rooms with high ceilings, use hanging products, for low ceilings, ceiling-mounted appliances with rigid mounts are suitable.

In rooms with a height of 2.5-3 meters, hang the chandelier at a distance of 2-2.2 meters from the floor. If the height of the room is more than three meters, the choice of location depends on your aesthetic preferences.

• The most durable and durable materials are glass, followed by plastic and metal. Fabric, paper, wood are flammable.
• For a spacious living room, choose hanging chandeliers with multiple bulbs.
• For kitchens, choose chandeliers with adjustable hanging cord length. Suitable ceiling lights with two or three shades. The main rule is ease of care, since soon carbon deposits will appear on the surface of the lamp after the fat drops have settled.

Do not buy textile lamps, it is better to look at options with decorative metal, glass or acrylic elements.

• For children's rooms, buy devices that are interesting in design: in the form of butterflies, flowers, fairy-tale characters. Lighting should be bright, but soft, not create glare and streaks on the walls.

Refuse models made of crystal or thin glass, choose safe materials - textiles or plastic.

• Lamps with a fabric or matte lampshade will fit favorably into the bedroom, they will give a subdued light. You can illuminate the reading nook with sconces or floor lamps with soft light.
• Use sconces to illuminate small rooms (hallways, corridors), with the help of lamps of this type, you can change the dimensions of the premises. Sconces with an upward orientation visually increase the space in height.

To expand the room, hang appliances on a wide wall. For a long and narrow corridor, choose products with a rectangular or oblong shape. Give preference to a chandelier with swivel spots that change the direction of light.

• For overhead lighting in bathrooms, use ceiling lights with frosted or white shades. To focus on the wash area or the mirror area, hang a sconce.
• If a floor lamp is needed for background lighting, its light should be soft and well diffused. If you want to illuminate only part of the room for reading or work, you will need a powerful device.

For convenience, use products with a table, as a decor - floor lamps. Select the height of the devices depending on the spatial dimensions of the room.

• Choose lamps for work according to functionality. Pay attention to how the light is reflected. The heavier the stand, the better the lamp will hold up. good options– lighting equipment with adjustable height.

The tripod of the desktop instrument must be flexible and change the angle of inclination.

• Choose the tone of the chandelier according to the interior. Dark shades absorb light, while white ones reflect. Greenish shades are calming, red ones are annoying. Universal option- fixtures that give a soft orange or yellow light.
• Lighting equipment should match the style of the room. Art Deco combines whimsical shapes and a variety of materials.

Country-style lamps are distinguished by the use of plant and rustic themes, made in yellow, light green shades. Cold tones and imitation of candles in shades are used for Provence-style lamps.

The urban loft uses a variety of design solutions: LED lights, spotlight chandeliers, spotlights, etc. The tiffany style is distinguished by openwork designs, the use of stained glass and forged elements.

• If the room is located on the sunny side, then you will use the lamp only in the evening. You can get by with a floor lamp or a hanging lampshade.

Rooms on the shady side need regular lighting. To do this, place the devices evenly around the room.

• Decide on the number of lamps. If you choose one appliance, it should stand out from other pieces of furniture. Use large or medium size products. When choosing a set, pay attention to the fact that it is made in one color.

Which is better

The best lamp should:

• consume little electricity;
• do not have interruptions in voltage;
• correctly positioned at the height of the room;
• be functional, be used for its intended purpose and illuminate the necessary space;
• have the necessary strength and brightness of light;
• be convenient to use and maintain;
• be made of durable and safe material;
• fit the room in size, radiation strength, color and style, fit into the overall design.

How to use

• To clean the fixtures, use special detergents with sprays. Before starting work, turn off the power supply and wait until the bulb has cooled down.

• The second way: remove the lamp, disassemble it in detail and wash it. Antistatic wipes can be used for cleaning.

• To wash crystal products, first apply to the surface of the device detergent. When the water starts to drain, wipe the equipment dry. After 2 hours, you can turn on the lamp.
• Wipe the plafonds made of frosted or transparent glass with a damp sponge soaked in a detergent solution.
• Keep wooden, fabric and paper sconces away from sources of fire. During repair, do not forget to turn off the power supply.

What is the warranty for the lamps

The warranty period for lamps is 18 months, unless otherwise specified in the device passport.

The warranty does not apply to products in the following cases:

• in case of violation of the rules of storage and operation;
• installation or repair was carried out by unqualified specialists;
• lighting equipment was connected to the network with the wrong voltage;
• the user has handled the device carelessly;

The presentation of the passport for the purchased goods and the warranty card is mandatory.

• Lack of wire contact with the cartridge. For repair, disassemble the design of the lamp. If the cartridge of the old model worked in the device, replace it with a new one. Check if the wire is firmly attached to the screws.

To increase the strength of the connection, it is necessary to additionally solder the ends of the wires.

• No wire contact with plug. The wire at the entrance to the plug often fails. With such a breakdown, the plug is cut off and replaced with a new one. Pay attention to the diameter of the plugs of the old part.

Solder the wire to the plug for a secure fit. You can add the diameter with a thick elastic band or electrical tape.

• Switch not working. Turn off the switch. Using a multimeter or tester, check how it works. If it cannot pass electrical signals, then the mechanism is out of order.

Replace the switch or connect the wires directly. Then the lamp will light up immediately after switching on.

• Broken wire. A sign of a breakdown is the flashing of a light bulb during transfer. Replace the wire with a new one with the same gauge. If the cord has tight bends, use plastic or rubber tubes to prolong the life of the equipment.

In case of serious damage, contact a specialist.

Floor lamp. How to decorate a room with floor lamps

Not everyone knows that it is impossible to put indoor floor lamps at the same height. Firstly, the room will be lit unevenly, and secondly, it will take on a dry official look.

The floor lamp creates a pleasant twilight, conducive to relaxation or reading books. Therefore, such lamps are installed mainly in bedrooms.

And the best distribution of chiaroscuro, visually enlarging the room, can be obtained by placing floor lamps of different sizes in the corners.

Spot and strip lights in the interior

They are an indispensable attribute suspended ceilings. Their appearance and location depend on the type of ceiling (matt or glossy), its color, wallpaper design, as well as the desired aesthetic effect.

How to choose the right lamps for a large and small room

A small room can be decorated with 3-4 small evenly spaced lamps. Visually, the room will become more spacious and brighter. Another option is one floor lamp with a wide and high lampshade. As a result, the room will also "expand" a little. If, in addition, the room has a low ceiling, only a floor lamp will fit into it. In this case, the top lighting will only visually bring the ceiling closer to the floor.

A lamp for a large room is not an example easier to choose. You can stop at the option with two large chandeliers located at an equal distance from the end walls and from each other. Another solution is one lush cascade-type chandelier or spot lighting (if there is a false ceiling).

One of the determining factors comfortable living in an apartment or house is normal, properly organized lighting of the premises. Starting repairs, many homeowners decide in parallel to replace old lighting fixtures with modern ones. It is clear that this requires at least a little understanding of their diversity.

There is also a second important point, which necessarily worries consumers - and how much light should the purchased lighting devices provide in the room? These questions are absolutely fair and are closely interconnected. We must not forget that not only the comfort in the house, but also the health of its inhabitants depends on the amount of light entering the premises. To understand these issues, you need to know what types of lamps are, according to what criteria they are divided, how they are optimally placed, and, most importantly, how many and what kind of lamps will be needed to fully illuminate the rooms.

Therefore, we will combine these problems in one article - types of lamps and

Criteria for choosing luminaires for residential premises

First you need to decide on the criteria by which lighting devices are divided, and then consider them in more detail. These may include the following questions:

• Luminaire installation area.
• The design and method of installation, the number and type of lamps used.
• Design solution - material, shape and style.

Luminaire installation area

According to this criterion, devices are divided into ceiling and wall, floor and desktop, suspended, mounted and built-in. Let's take a closer look at what they are.

• Ceiling lamps . This type of device is placed on the ceiling surface or built into it. They can, in turn, be subdivided into suspended, built-in and stacked in special niches, as well as fixed on the ceiling with the entire plane of the back of the device.

Pendant lighting accessories include chandeliers that can be designed for a different number of lamps. Chandeliers are usually used to illuminate rooms with high ceilings, and they can have very diverse, sometimes very unexpected designs.

This type of lamp will always be appropriate in, the only thing that needs to be considered when buying it is the style of the interior in which the chandelier must be entered. Here you need to take into account the color, shape and number of lamps of the lamp, as well as its massiveness. IN small room a large chandelier will create an oppressive mood and look clearly out of place. If the ceiling is low, then it is best to choose a ceiling lamp that is not hung on a hook, but is fixed directly to the ceiling.

Embedded devices are used for and - they are usually called point in a different way.

Ribbon and tubular lighting fixtures are placed in specially mounted niches of a multi-level ceiling. They are most often used for decorative lighting and as additional lighting to the main one.

• Wall lighting fixtures . This type of product includes sconces familiar to everyone, as well as the above-mentioned recessed spot, strip and tubular lamps, which are also used for additional lighting and are fixed in niches or directly on the walls.

The sconce can be used for both indoor and outdoor street lighting when they are installed on the walls of a house or adjoining buildings.

You can’t do without sconces in the bedrooms - it is customary to fix them at the head of the beds. Subdued light that extends to a certain area of ​​​​the room does not interfere with the rest of the other inhabitants of the room.

• Floor lamps. The most popular of this type of lighting can be called floor lamps, which are usually installed near an armchair or sofa, that is, places where it is customary to spend time with a book or needlework.

In addition to floor lamps, there are other options for floor fixtures, but they are more often used as decorative or as additional to general lighting.

• Table appliances most often used to illuminate the table or bedside area - in the latter case, they are installed on the nightstand in the bedroom. Can't do without a table lamp desk, especially if there is a student in the house, so this type of lighting is in almost every home.

In the same section, it is necessary to include the division of lamps into groups according to their purpose:

• Devices for general lighting are designed to supply the main light into the room. These mainly include ceiling lights.
• Local lighting devices are used to supply light to a specific area of ​​the room, for example, on a work surface, bedside area, kitchen sink, etc. These lamps include sconces, table and floor fixtures.
• Lamps for combined use. Their function can be performed by ceiling and wall lamps installed along the walls and having a brightness control - a dimmer.

Thanks to this installation and regulation, the light can be bright and illuminate the entire room, or serve as a backlight for other lighting fixtures.

• Decorative lamps. This group of lighting fixtures is designed to create a special mood in the room or maintain the style of the interior.

In addition to the "piece" application, whole panels are created from some lamps. When they are turned on, certain geometric or chaotic patterns are created on the wall or ceiling. To create a decorative effect, ceiling, wall and some floor lamps are used.

• Exposure lamps. The purpose of these devices is to highlight objects that need to highlight some objects or areas of the interior. This group can include ceiling pendant lamps, adjustable in height, as well as devices mounted on tires. In addition, wall-mounted options are also suitable for a similar purpose.

Design and installation method

• Stationary lamps are fixed in one place and connected to the general lighting system of the house. These include all ceiling lights and most wall lights.
• Mobile lamps plugged into a power outlet and can be moved to any area of ​​the room or to another room. Almost all floor, table and some wall lamps belong to this category of devices.

Since the fixtures differ in their design, their installation also occurs in different ways. The easiest way, of course, is to install and connect floor or desktop appliances.

• Chandeliers. To hang these luminaires, a special hook is mounted on the ceiling, and then commutation is carried out with the power supply. True, the hook is not the only way to attach chandeliers, since many fixtures of this type have their own suspension system.

Is it difficult to hang and connect the chandelier yourself?

It all depends on the degree of "technical savvy" of the owner of the apartment, the availability necessary tool and from the design of the chandelier itself. You can get acquainted with the order of work in order to assess your strengths in a special article of our portal.

• Ceiling lamps, fixed directly to the ceiling surface, fixed on it with the help of special fasteners, usually included with the product.

• spotlights, embedded in drywall ceiling surface or in a stretch ceiling, may have different fixing structure, but the most common can be called spacer, when the lamp is held by the ceiling surface with the help of special spring-loaded "lugs". When installing connected to electric cables lamp into the hole prepared for it, these "ears" are bent, and then released - they tightly press the device from the inside to the ceiling surface. Only the front part of the lamp remains visible, while the rest of its structure is hidden inside, into the space formed between the ceiling and the suspended (tension) structure.
• Tire lights. This type of lighting fixtures is installed in special profiles or mounted on metal rods.

The lamps themselves are mobile - they can move along the profile or rod, as well as turn in the right direction, which allows you to create the desired intensity in a particular area of ​​the room.

• Sconce can be hung on brackets fixed to the wall surface or screwed directly to it. This version of the fixtures can be connected through a socket or be built into the electrical system of the house and controlled through a switch.
• Tapes and tubes with LEDs connected to a switch or an outlet. Such lamps are used for illumination in addition to the main lighting, and fit into niches made of plasterboard and fixed under the ceiling or on the walls. In rare cases, this lighting option is fixed directly to the walls using special clamps. Often, such devices require a separate step-down transformer and a special control unit.

Design decision - material, form and style.

This important criterion is considered by many consumers in the first place, since the lamp is initially selected according to its appearance. This item includes such characteristics as the material of manufacture, the shape of the ceiling lamps and the frame of the lamp, their color, as well as the style in which the device is made.

• Speaking about the material for the manufacture of lighting fixtures, it is necessary to mention both its frame and shades.

The frame of the lamps is most often made of metal, on which a certain coating is applied, in harmony with other elements of the device - it can be gilding, nickel, silver, bronze or some color shade. Recently, more and more manufacturers are replacing metal with plastic, and then applying the above-mentioned decorative coatings to it.

In addition, the frame can be made of wood, and for this purpose, both processed wood and beautifully curved branches are taken.

Quite often, the frame base is made of several materials. So, for this purpose, wood and metal, plastic and metal, and other combinations can be used in combination.

Prices for spotlights

Spotlights

Plafonds for lamps for various purposes and installation sites are mainly made of glass or heat-resistant plastic, but floor lamps and table lamps are quite often covered with a light-diffusing lampshade made of fabric stretched over a metal frame. In addition, the plafond can also be metal, but such lamps are intended only for local or exposure illumination, for example, to illuminate a desktop.

• Describe everything existing forms ceiling lamps and lampshades of lamps is almost impossible, they are so diverse - they can vary from regular geometric to completely asymmetric.

In addition, plafonds can be decorated with different reliefs or made in the form of flower buds. Moreover, the shape is often chosen depending on which style the lamp is selected for.

• A few words need to be said about the styles of lighting fixtures. IN last years in interior design, the most popular are several styles, so to speak, close in spirit to Russian residents of different age categories.

High tech. Young couples often decorate their homes in one of the areas of minimalism - high-tech style. And for lighting rooms decorated in this way, ceiling lights on tires, strip and tubular LEDs for lighting, metal floor lamps with small lampshades made of glass or nickel-plated are excellent.

Speaking about this style in general, it must be said that the correct forms of accessories, metal coatings and a minimum number of pieces of furniture are inherent in it.

Romanticism . This style is dominated by light delicate shades, fuzzy drawings with the inclusion of plant elements, as well as birds. The frame of lamps for the interior in a romantic style can be made of light metal for gilding or silver or plastic imitating metal), as well as wood.

Lampshades for lamps are most often made of impregnated fabric or plastic with a woven pattern, but can be made of glass. The most characteristic form of lampshades for a romantic style is a cut cone or hemisphere. Romanticism uses different types fixtures at the location - these are ceiling (chandeliers), wall (sconces), floor (floor lamps) and table fixtures. romantic style well suited for decoration, as its shades are filled with freshness and pastel calm, which will contribute to a good rest.

Country - This is a "rustic" style with all the elements inherent in this area of ​​\u200b\u200bresidence, mainly made from natural materials. Appropriate for an interior decorated in this style, a large chandelier and a floor lamp with a fabric lampshade on metal frame, wooden lamps with lamps stylized as candles, as well as sconces with a round milky white shade, etc.

However, this style is usually used to decorate private houses, since in order to fulfill all its requirements, high ceilings and spacious rooms are needed, which is difficult to comply with in a typical city apartment.

Neoclassic suitable for decorating both a house and an apartment with high ceilings, as this style is characterized by a large massive chandelier with numerous lamps and pendants. However, this style can be mixed with modern fixtures and fixtures that have "antique motifs". So, to illuminate the ceiling, tape or tubular LED lights, as well as point devices, and all of them will be in perfect harmony with a crystal chandelier.

Since neoclassicism involves a large amount of light, it would be useful to install lights in it in open pieces of furniture, such as bookcases or shelves for decorative elements.

If you decide to decorate the interior of the room in other styles, then before buying lighting fixtures, you should find out more detailed information about them - it is in abundance on the Internet.

Choosing a lamp for a lamp

When choosing lighting fixtures, you need to pay attention to which lamps can be used in them. If until relatively recently there was only one non-alternative option - these are ordinary incandescent lamps with different powers, today the industry offers more economical and durable products.

One of the options already mentioned above is LED lamps, which are produced in different forms. But besides them, on sale you can find halogen and fluorescent. In Russia, the usual incandescent lamps are still very popular, but in Europe they were practically abandoned due to the high energy consumption and fragility. Certain steps in this direction, reception at the highest level, are being taken in our country as well.

Each type of lamp has a base, which must match the lamp socket. Therefore, when choosing lighting fixtures in which the sockets are designed, say, for halogen lamps, you should remember that the bases of ordinary incandescent lamps may not fit them. But at the same time, there are also interchangeable types - the base, for example, LED, fluorescent and conventional lamps can completely match.

To choose correct option, you need to figure out what you should pay special attention to.

General parameters of lamps for fixtures

So, when purchasing lighting devices, it is necessary to study the characteristics located by the manufacturer on the packaging, the following parameters should be indicated there:

• Plinth type. As mentioned above, different types of lamps can have different bases. Their main types are shown in the figure below:

If there are only three of them on ordinary incandescent lamps - these are E14, E27 and E40, and the E27 base is the most common and used in everyday life, then LED, halogen and fluorescent varieties have much more. Therefore, when purchasing a lamp, you should immediately pick up a lamp for it. The selection of lamps, by the way, is not a very simple matter, depending on many parameters - this will be discussed in more detail below.

• The power of the device. This value indicates the consumption of electricity by the lamp in a certain unit of time (usually an hour is taken as it). This comparison table presents the approximate power of different lamps to obtain the same luminous flux:

Incandescent lamps, W	Fluorescent lamps, W	LED lamps, W	Luminous flux, Lm
20	5÷7	2÷3	250
40	10÷13	4÷5	400
60	15÷16	6÷10	700
75	18:20	10÷12	900
100	25÷30	12÷15	1200
150	40÷50	18:20	1800
200	60÷80	25÷30	2500

From these data it is immediately clear that fluorescent and LED lamps, with much lower energy consumption, give the same luminous flux as incandescent lamps.

• Light flow- this value, which is mentioned in the above table, is measured in Lumens ("lm" and "lm") and characterizes the light output of the device.
• Operating temperatures of devices. The temperature range specified by the manufacturer on the package guarantees trouble-free operation of the purchased device. It is especially important to pay attention to this parameter when buying LED lamps, since some of them are not designed for use outside heated buildings.
• Colorful temperature - this characteristic determines what color the radiation has a lamp. This parameter is called color temperature due to the fact that at different heating intensities the lamp can emit light that differs in hue. For example, a lamp with a tungsten filament, when heated to 900 degrees, emits a reddish tint of light, and when the temperature rises, it will change.

Incandescent lamps when heated have a color temperature of 1900÷2500 degrees, depending on their power. When choosing the color temperature of the LED lamp, you need to provide for its installation location. So, if the package indicates a temperature of 1600 ÷ 2200 degrees Celsius or 2700 ÷ 3300 Kelvin, then the light from the lamp will have a warm, even shade, and it is perfect for living quarters.

With parameters of 3900 ÷ 5000 degrees Celsius or 4200 ÷ 5400 Kelvin, the light from the lamp will be cold, close to daylight. Such lamps are suitable for rooms in which there are no windows to the street, that is, there is no daylight.

Since manufacturers typically list lamp color temperatures in Kelvin, this table will help you easily select the right shade.

• Degree of protection- a characteristic that shows the degree of protective sealing of the device from the ingress of moisture and dust into it.
• Working voltage- this characteristic shows the required voltage in the network for the operation of the device. The mains voltage standard adopted in Russia is 220V. But many lamps require a different voltage, that is, connection through special transformers or power supplies. So it is impossible to lose sight of such a parameter when choosing a lamp.
• Life time. This parameter indicates the approximate operating time (so to speak, "motor resource") of the product before failure. This period is determined by the manufacturer, but should not be confused with the warranty period.
• Dimensions - these are length, width and height (L×W×H). It is necessary to pay attention to this characteristic due to the fact that the closed shades of lamps can have different heights, and an unsuccessfully selected lamp may not fit in it.

Now it’s worth a little more understanding of what modern lamps are.

LED bulbs

LED type lamps can be safely called an environmentally friendly light source, since safe components are used in their production and operation. Unlike some other varieties, such devices do not contain mercury, therefore, even if the case is damaged, they do not pose a danger to the environment and humans.

LED lamps at the dawn of their appearance consisted of a base and a housing in which a board was installed with the necessary electronic elements and LEDs soldered in. At first, they were most often used for local or exposition lighting fixtures, since due to their design feature, the LEDs shine in one direction.

Prices for fluorescent lamps

fluorescent lamps

Recently, however, LED lamps have also been produced for general lighting. They are given a variety of shapes - spherical flasks, by analogy with conventional incandescent lamps, flat, cylindrical and others, and with the right installation location, they are already able to illuminate the room completely.

The advantages of this type, in contrast to the usual incandescent lamps, include their following characteristics:

• Small power consumption.
• Long service life, as manufacturers claim their resource is 30,000÷50,000 hours of continuous operation.
• Low body heating temperature with high efficiency luminous flux.
• Mechanical strength of the protective housing.
• The ability to manufacture lamps of any shape, including very compact ones.
• Environmental safety of products, as they do not contain not only mercury, but also other toxic substances.

The disadvantages of high-quality LED lamps are insignificant. Basically, all the identified “minuses” can be attributed to their manufacture, since unscrupulous manufacturers do not comply with the norms established by the standards. These include the following points:

• The use of unstable plastics for the manufacture of the case and board, containing formaldehyde resins and phenols that are hazardous to human health.
• Lamps with a simple driver installed in them sometimes give a flickering effect.
• The low quality of the components and their assembly into the overall design, that is, the "indiscriminate" savings on the details provided for by the standards - this leads to the flickering of the LEDs, excessive power consumption, overheating and melting of the case, failure of the LEDs.
• High price for high-quality products, in accordance with the standards. On the other hand, the cost of LED lamps has recently fallen sharply and this trend continues. So they are gradually moving into the category of public.

It should be noted that in the Russian market it is not so easy to find lamps made in accordance with all requirements, so there is a rather high probability of purchasing low-quality products that come in bulk from the eastern borders.

If you decide to use LED lamps in fixtures, then you should not save on them by choosing the cheapest models. Properly manufactured devices should be equipped with a driver with a power factor corrector and a frequency corrector, as well as a ceramic capacitor. The lamp should be made of environmentally friendly plastics and without the use of lead for soldering LEDs. All these factors require considerable production costs, which makes quality products more expensive.

And it is completely unacceptable to buy LED lamps sold without packaging and without indicating all the necessary data about their characteristics.

Halogen lamps

Halogen incandescent lamps consist of a body and a glass bulb various forms filled with gas. Usually these are vapors of a mixture of iodine and bromine - such a composition increases the resource of the coil, which heats up to 3000 °K up to 2000 ÷ 4000 hours.

Halogen lamps are often used for local lighting, that is, they are installed in spotlights or table lamps with the appropriate connectors and powered by AC or DC, but using a smooth turn on of the device. In this case, the service life of the lamps is increased to 8000÷12000 hours.

Powerful halogen lamps are also produced up to 150 and 230 W by the standards of incandescent lamps. They are used in spotlights and ramps, for drying materials in industrial environments.

Halogen lamps can be equipped different types plinths and be appropriately marked:

• MR lamps are designed primarily for use in automobiles, but they are also used for installation in household lighting, in which case they work through a transformer.
• GU lamps are used in conventional lighting and work without a transformer.
• Lamps with an E14 or E27 base are used in the same way as conventional incandescent lamps. They are additionally closed with an external flask, which protects the main quartz flask with a tungsten spiral from contamination and contact, as well as from contact with fusible materials.

• IRC-marked halogen lamps are distinguished by the presence of a special coating on the bulbs that transmits the light produced, but delays infrared radiation, reflecting it towards the spiral. This lamp has a high efficiency. So, a device with an equivalent power of only 65 W produces a luminous flux of 1700 Lm.

The advantages of halogen lamps include the following characteristics:

• The expressed compactness of products.
• Fairly long service life.
• High product efficiency.
• A good light temperature, most often located in the range of 2800 ÷ 3000 °K, is warm shades of light that are most comfortable for human eyes.

Disadvantages of halogen devices:

• The presence of a non-harmful gas inside the shell of the lamps, which, if the devices are damaged, can adversely affect the state of human health.
• Damaged or worn-out lamps cannot be stored in the house for a long time - they require special disposal.
• Low resistance to humidity, so they can not be installed in bathrooms.
• The cost of halogen lamps is higher than the price of conventional incandescent lamps.

Fluorescent lamps

This type of lighting elements in everyday life is called fluorescent lamps. They consist of a glass flask coated with inner surface a layer of phosphor - a special mixture that contributes to the brightness of the glow. The flask, under a pressure of 400 Pa, is filled with argon and mercury vapor or amalgam - they contribute to the creation of ultraviolet radiation when an electric discharge occurs inside the container.

The luminous efficacy of this type of lamp is much higher than that of conventional incandescent lamps. Service life, at quality workmanship, is about five years.

Fluorescent lamps are divided into low and high pressure. The latter are used for street lighting, as they have a higher power. lamps low pressure are used for installation in lamps used in industrial and residential premises.

Fluorescent lamps, due to their brightness and economy, have long been widely used for lighting public office buildings, hospitals, schools and kindergartens. But if earlier lamps of this type were produced in only one configuration, and for them it was necessary to purchase a special lamp, today numerous models with an E27 and E14 base are on sale, so they can easily replace conventional incandescent lamps.

Prices for halogen lamps

halogen lamps

The advantages of fluorescent lamps can be called:

• High efficiency and light output. So, a fluorescent lamp with a consumption of 20 W gives a luminous flux equivalent to that of a conventional incandescent lamp of 100 W.
• These lamps are produced with different color temperatures, that is, they can have different shades, while giving a diffused soft light.
• A very considerable resource, sometimes reaching 20,000 hours. However, it is possible for well-made and correctly connected lamps, and usually practical indicators are more modest.

The disadvantages of fluorescent lamps include the following points:

• The increased fragility of the lamps - they must be handled with extreme care.
• The presence of mercury inside the flask, the total amount of which can be from 2.3 mg to 1 g. Therefore, when the flask is depressurized, the lamp becomes an object of chemical hazard.
• Sometimes there is an uneven luminous flux, sharp for the eyes or causing distortion of the natural color of objects.
• With prolonged use of lamps, their internal coating is gradually destroyed, which leads to a change in color temperature, a decrease in light output, and as a result, a decrease in efficiency.
• The appearance of a flickering effect, due to aging or due to poor-quality workmanship.
• In addition to the above, there are additional minor shortcomings.

The letter marking of fluorescent lamps for domestic use according to GOST 6825-91 for color temperature is as follows:

• LB - white light
• LD - daylight
• LE - natural light
• LHB - cold white light
• LTB - warm white light

If the letter “C” is added at the end of the letter marking, this means that the lamp has an internal coating of a phosphor with improved color rendering - “de-lux”. The addition of two letters "CC" means that the coating will provide high quality color reproduction - "super deluxe".

How to choose lamps in terms of power to ensure normal illumination?

The choice of lamp power for fixtures depends on several factors, therefore, in each case, this parameter may be different, but the main ones include the following:

• Availability of natural light.
• The height of the ceilings in the room.
• Room area.
• The desire to create special intensity in certain areas or special effects.

But if we proceed from the positions of optimal illumination, that is, without creating any effects, then a simplified version can be used to carry out the calculation, or “dig deeper”.

A simplified method for calculating the required lamp power for lighting

If we rely on the standards developed by experts, then according to them, lighting 1 m² of a room will require a power of 15 ÷ 20 W, based on the conventional equivalent of incandescent lamps. So for modern apartments with a standard layout, you need to provide:

• For a living room of 18 m² - 270÷360 W
• For smaller living rooms - 150÷200 W
• For the kitchen - 100÷150 W
• For the corridor - up to 200 W
• – 100÷120 W
• For toilet - 60÷80 W

If indoor installations are considered different kinds lamps, then in order to navigate in their choice, you can use this table:

Room area, m²	LED lamps (LED), W	Fluorescent lamps (CFL), W	Conventional incandescent lamps (LN), W	Luminous flux, Lm
1	2÷3	5÷7	20	250
2	4÷5	10÷13	40	400
3	6÷10	15÷16	60	700
4	10÷12	18:20	75	900
5	12÷15	25÷30	100	1200
7÷8	18:20	40÷50	150	1800
10÷12	25÷30	60÷80	200	2500

But this is a very simplistic approach that does not take into account many important factors. Therefore, the discerning user is encouraged to make more accurate calculations.

Algorithm for self-calculation of illumination - with calculators

The illumination of the room, as already mentioned, must meet certain standards. And the main task of the calculation is the selection of such a number and characteristics of lamps that will ensure the maximum possible correspondence of artificial lighting to natural, most favorable for human perception.

The calculation algorithm assumes to build on the existing sanitary standards for illumination established by the current SNiP. It is carried out, of course, for the main lighting devices. Decorative and local lighting do not belong to them - there the user is free to choose the level of illumination on his own, especially since many devices for this purpose are also equipped with dimmers.

So, the calculation will be based on the following formula:

Fl = (En ×Sp ×k ×q) / (Nc ×n×η)

And now, slowly, let's deal with all these indicators included in the formula

• Fl- the calculated luminous flux, which each lamp installed in the luminaire must have. That is, exactly the value that is required to be determined.
• Yong- recommended parameters of illumination of premises in residential buildings established by SNiP 23-05-95. This indicator is measured in lux (Lx) and must correspond to the following values:

Type of premises of a residential building	Recommended norm of illumination of working surfaces in the premises of a residential building, lx
Living rooms	150
Sleeping	150
Baby	200
Kitchens	150
Corridors, hallways	150
Bathrooms, restrooms, shared bathrooms	150
Vestibules	30
Stair flights and landings in the entrances	20
Floor corridors and platforms	20

As you can see, there is no particular variation in the values ​​for residential premises - only a few stand out against the general background. Higher, in the region of 200 ÷ 250 Lx, lighting may also be required for a home workshop if fine work is to be performed there. However, this is usually solved by installing an additional local lamp, for example, a table lamp.

• Sp - This is the area of ​​the room in which it is necessary to provide the required level of illumination. We will not dwell on the calculation of the area - for rectangular rooms this is the product of length and width, for more complex configurations it is required individual approach. However, for such special occasions we'll give you a hint.

How to calculate the area of ​​a room if it's not a rectangle?

The school geometry course, sometimes, is forgotten, and the non-standard configuration of the room can put the owner in a difficult position when calculating the area. It's okay, follow the link to the article devoted to it - it contains many examples, convenient calculators are posted.

• k is the so-called safety factor. It depends on the type of lamps planned for installation (taking into account their ability to gradually lose their glow intensity) and on the degree of dustiness of the premises, that is, the presence of interference with the propagation of light. Since in residential premises, presumably, the owners do not allow strong dustiness (more than 1 mg / m³) or a high concentration of vapors, this coefficient can be considered equal to:

- for gas-discharge lamps - 1.2;

- for conventional incandescent and halogen lamps - 1.1;

• q- coefficient of non-uniformity, especially important for rooms where accurate visual work, constant reading or recording, etc. are expected.

It is taken equal to:

- for incandescent lamps and mercury discharge lamps - 1.15;

- for basement luminescent (so-called energy-saving) and LED - 1.1.

• Nc- the number of fixtures planned for purchase and installation in a particular room.
• n- the number of horns (installed lamps) in one lamp.

It is clear that these last two parameters will set the total number of lamps that will work in the room. Naturally, if the calculation is carried out for only one lamp, both of these values ​​\u200b\u200bshould be equal to one. In this case, the final result will show the total luminous flux required for normal lighting of the room.

• η - coefficient of use of the luminous flux. With this value, it is somewhat more difficult, since one more preliminary calculation will have to be performed.

To find the utilization factor from the tables, we first determine the so-called room index. It is calculated by the following formula:

i =Sp / ((a +b) ×h)

i- room index.

Sp– area of ​​the room, m².

A And b- the length and width of the room, expressed in meters

h– The planned height of the luminaire relative to the floor level. It is important - not the height of the ceiling, but the excess of the lamp above the floor. For example, the ceiling has a height of 2.7 meters, and a chandelier is purchased with a suspension rod length of 60 cm. This means that our lamp height is 2.7 - 0.6 = 2.1 m.

After the calculation, the resulting value is rounded up to the nearest 0.5; 0.6; 0.7; 0.8; 0.9; 1.0; 1.1, 1.25; 1.5; 1.75; 2.0; 2.25; 2.5; 3.0; 3.5; 4.0; 5.0.
