When planning the lighting of a living space, one should be guided by the fact that lamps must emit uniform light, consume energy efficiently and have a long service life. These are the requirements that meet LED luminaires for indoor lighting . In addition, their compactness and low weight make it possible to mount them on walls and ceilings made of almost any material.
LED lighting confidently leads in almost all basic parameters, leaving far behind not only incandescent lamps, but also fluorescent and halogen light sources. The use of LED lamps for interior lighting of residential and industrial premises is due to a number of exceptional qualities:
- economic efficiency - an LED lamp consumes 10 times less electricity than incandescent lamps of similar brightness, and is 40% more economical than fluorescent light sources;
Device
- Duration of operation – LED lamps can operate for 11 years of continuous operation, which is 100 times greater than that of a conventional lamp;
- strength and safety - thanks to the absence of filaments and glass cases, LED lamps are resistant to shock and vibration: even a fall from a height of one and a half meters will not affect the operating parameters of the lamp. The lack of heating makes them fireproof;
- silent operation, absence of UV radiation - LED lighting devices emit smooth, flicker-free light, unlike fluorescent lamps, the glow of which is accompanied by clicks, squeaking, one-time shutdown, and generation of ultraviolet radiation;
- maintainability and recycling - lamps can be easily replaced by soldering, and disposal of unusable lamps does not require special technologies;
- wide temperature range – LED lighting can function in difficult conditions at temperatures from -60 to 50° WITH;
- lighting directionality – a huge range of LED modifications with light dispersion at an angle from 10 to 140 degrees;
- ease of installation - the presence of standard contact connectors makes it possible to install LED lamps in place of previously used pendant and built-in devices. In addition, the design of the lamp does not require the installation of additional devices (electronic ballasts).
This range of advantages allows the use of LED lamps in lighting living rooms and technical premises: bathrooms, storerooms, dressing rooms, corridors, staircases, as well as in public buildings: hospitals, offices, libraries and other organizations.
Types of overhead LED lamps for interior lighting
The main feature of overhead lamps is that you can plan their installation not only at the stage of repair work, but also after this process is completed. Such lighting will also be an excellent solution for those who are thinking of using it to illuminate furniture or accent lighting of individual areas of the room.
Depending on the method of attachment to the surface, surface-mounted lamps are classified into wall and ceiling lamps. Depending on the purpose of the premises where the lighting fixtures will be located, they are:
- for the living room - as a rule, these are square or round overhead LED lamps with elegant shades that echo the style of additional lighting devices;
- for the hallway - taking into account the configuration of the room, you can use one or more round or rectangular lamps or a series of wall-mounted point structures;
- for a nursery - depending on the style of the room, you can choose thematic models in the form of a ball, sun, butterfly, etc. You can create a whole composition by adding small night lights to the lamps;
- for a study - overhead lamps for this room are selected in a seasoned design, complete with;
- for the kitchen, bath and toilets - use devices of various shapes with sealed shades that are most suitable in design;
- for utility rooms - here you can use models of square, rectangular or round shape, with fastening to both the ceiling and the wall.
Helpful advice! Applicationoverhead LED lights for the kitchen under cabinetsmakes the use of the main light source minimal.
Models of overhead wall-mounted LED lamps for the home have mechanical strength, resistance to vibration, and some of them are designed to be anti-vandal, which allows them to be installed in rooms with difficult conditions, including entrances or other fairly accessible places.
LED luminaires for indoor lighting: recessed models
LED lamps are a single independent design and have compact installation dimensions. They can be used not only as sources of main light, but also for accent lighting of individual zones and elements. Due to the variety of shades of glow, such devices are used to decorate interiors in any color options.
Recessed LED spotlights
Spot lighting is one of the most popular ways to transform an interior using lighting. The design of spotlights consists of a body hidden in the surface and a front part consisting of a light bulb, diffuser, reflector and other decorative parts. Their main advantages are compactness, rigor and versatility of use.
Round LED recessed luminaires are available , square and rectangular shapes. Based on the type of case, there are thin and standard models. They have several glow colors, including cool, warm, day white and multi-color. In addition, models are available that differ in the angle of illumination: with a narrow (up to 45 degrees) and wide beam.
Such devices are mounted using special spring-loaded brackets. To do this, holes are made in the surface of a smaller diameter than the front part of the spotlight, which makes it possible to hide the installation gap. After connecting the wires, the brackets are pulled together to the device and the housing is inserted into the hole. Thanks to this simple mounting method, spotlights are easy to install and remove.
Helpful advice! When choosing a spot model, pay attention to the fastenings: the material of the brackets must be strong to support the weight of the lamp.
The versatility of spotlights lies in the fact that they are used both for organizing general lighting and for local illumination. They are ideally suited for lighting design of ceilings, niches, arches, beams, as well as decorative elements. There are models of lamps that have a rotating design. By rotating their moving part around their axis, you can direct the light to a specific element of the interior.
Models of furniture recessed LED lamps
Given their small size, lack of heating and low energy consumption, LED lamps are built into cabinet furniture, located both inside and outside. Such lighting can be equipped with additional options: turning on when opening a drawer or cabinet door, illuminating the contents of dressing rooms, creating a direction of light flux.
The range of manufactured models of built-in furniture lamps is quite diverse. These are lamps of round, triangular and square shapes, the designs of which are completely mounted into furniture, leaving only a decorative frame on the surface. Both individual devices and sets consisting of two or three or more lamps are sold.
To create a shadow-free zone on the working surface of the table, it is more economical to purchase a system of five lighting fixtures, which includes mounting wires, a converter and a power cord. The model is very convenient for use in closets and dressing rooms. 12 volt LED lamp with side button. Their standard length ranges from 25 to 60 cm. It is possible to order a product up to 1 m long.
Furniture lighting greatly increases the comfort of using cabinets and dressing rooms. And the lighting design of niches and shelves effectively emphasizes the elements of the interior, making it more prominent.
Helpful advice! When choosing lamps for furniture lighting, it is necessary to take into account the purpose of the room where the furniture is located. If this is a kitchen or bathroom, you should use lamps with special protection from moisture and splashing water.
Design of recessed linear LED luminaires
Linear luminaires are built into ceilings and walls made of plasterboard sheets, slatted panels and other coverings. Using connecting elements, they can be mounted either in a single line or with the transition of the light circuit from the ceiling to the wall at an angle of 90 and 270 degrees. The design of such a lighting device consists of an aluminum housing, an LED board and a plastic diffuser.
The advantageous difference between such light sources and luminescent analogues is that lighting the area with LED lamps requires 3 times less electricity. And their service life exceeds energy-saving models by 8-10 times. In addition, with a continuous arrangement of linear luminaires, there is no effect of dark spots, which allows you to create unimaginable lines of uniform glow.
Linear lighting systems turn on instantly, and the number of turns on/off does not affect the duration of use of the lighting fixtures. Linear lighting structures are used for interior lighting of residential, office, industrial premises, warehouses and agricultural facilities: greenhouses, poultry houses, etc.
LED lamps with motion and light sensor
There are situations when it is necessary to use backlighting in places where it is difficult to supply power or where inconsistent lighting is required, which would function only if there were people in this area. For these purposes, it is intended to use LED lamps with battery-powered motion sensors.
Such devices operate on 4 batteries (AAA batteries) and have 6 LEDs in their device, which are capable of creating quite powerful lighting. A special feature of lamps with a motion sensor is their long service life (the batteries last for 2.5-3 months), as well as the ability to adjust the brightness, turn-off delay time and sensitivity of the motion sensor.
Main parameters of lighting devices with a motion sensor:
- operating voltage – 3V;
- Duration of operation of LEDs in “failure” mode is over 80,000 hours;
- adjusting the brightness of the glow;
- setting different shutdown delay modes (20, 60, 90 sec);
- sensor sensitivity – up to 3 m, angle 90 degrees;
- power consumption 65 mA - in operating mode, 0.35 mA - in standby mode.
The scope of use of this type of lamps includes lighting of staircases, dark corridors, halls, storerooms, and dressing rooms. Such lamps are appropriate in houses where families with children live: a child can go to the kitchen or toilet room at night without fear. In addition, such lighting devices can perform the function of emergency lighting.
With motion sensor
LED lights with battery: emergency lighting
Emergency lighting devices are used in emergency conditions for the evacuation of people or in cases where the power supply is turned off. Main feature LED emergency lighting lamps with battery is the ability to function independently of the power supply. The autonomous power supply is charged from the mains when it is supplied in normal mode.
There are several modifications LED battery-powered emergency shutdown lamps:
- intermittent action - these devices only work when the main power is turned off. When voltage is supplied to the network, it is used only to recharge the built-in power supply. The duration of operation in emergency mode is from 1 to 4 hours depending on the capacity of the battery model;
- continuous operation - when there is a power outage, such lamps automatically switch to battery-powered operation. This allows them to be used not only as emergency lighting, but also as lighting for rooms where there are frequent power outages;
- combined - such devices have a system of several lamps, some of which operate only from the mains when there is voltage, others - only from the power supply when there is no power supply.
Emergency power supplies for LED luminaires can be built into their housing. If the free space in the lamp housing is limited, it is necessary to provide smaller battery models or install the power supply in an additional separate housing.
Helpful advice! When using emergency lamps with a battery, you should take into account the temperature conditions of their operation, since power supplies are quite sensitive to temperature changes.
The main application of emergency lighting is in public places: shopping centers, administrative premises, children's institutions, hospitals, sports complexes and other facilities.
Armstrong LED lamps: prices for lighting fixtures
Taking into account the popularity of using Armstrong suspended ceilings in administrative, industrial and commercial premises, lighting manufacturers have developed models of LED lamps that are built into the ceiling structure without compromising the integrity of the surface. Such lighting devices are easy to install and significantly save energy consumption.
The dimensions of Armstrong ceiling lamps are identical to the standard dimensions of suspended ceiling slabs 600x600 mm. Thanks to this, to organize lighting, it is enough to install lighting fixtures in the cells of the suspended structure. In terms of luminous flux brightness, LED lamps are guaranteed to replace two conventional fluorescent devices.
The environmental friendliness of LED lamps plays an important role: unlike fluorescent analogues, they do not contain mercury. In addition, when one of the fluorescent lamps fails, the lighting device begins to emit flickering light, which negatively affects the vision of people in the room. If the network voltage is unstable, fluorescent lamps have to be changed frequently.
Price of LED lamp Armstrong 600x600 mm produced by the Novy Svet company (Russia) is 1100 rubles. The 39 W lighting fixture is designed for a supply voltage of 220V, weighs 2.5 kg and has a built-in design. High LED luminaire power factor (0.9) facilitates the operation of the lighting structure without loss of energy.
The cost of Armstrong lamps depends on the number of devices purchased. The larger the quantity you order, the lower the price of one lamp. Many companies have discounts and sales. The minimum retail price is 980 rubles, wholesale buyers are offered a price of 880 rubles. a piece. The products are provided with a warranty from the manufacturer.

WITH The desire of consumers to save energy costs has led lighting manufacturers to a compromise decision to begin producing technologically new products. LED lamps for indoor lighting of various types, sizes and modifications for home use have appeared on sale.
In terms of its structure, the simplest LED is a device for moving electrons from one level to another. When moving, energy is released, which is compensated and converted from electrical energy into visible radiation.
Each device includes power supplies, special optical devices and elements for heat dissipation. Depending on the installation method and location, the set of working elements may also include:
- cables for connecting to a power source;
- docking connectors;
- jumpers and other parts for various purposes and configurations.
A variety of design solutions in the design of lamp housings for a children's room helps to create home coziness and comfortable conditions for leisure and sleep..
Lighting for offices and home libraries
Designing home offices or libraries and selecting the necessary lighting is always a challenging task for designers. Proper selection of lighting fixtures increases the efficiency of using such rooms and gives the premises a comfortable feel.
The degree of illumination, color rendition and distance from window openings should create an imitation of daylight without the formation of glare on the monitor or polished screen. Various types of LED interior lighting fixtures placed on the ceiling and walls help create a calm, creative environment in offices and libraries.
incandescent lamps are gradually becoming a thing of the past, giving way to more high-tech ones. This is not surprising, because light diodes are durable and economical. The scope of their application is varied - from the automotive industry. Today we’ll talk about what LED lamps for indoor lighting are, let’s look at their pros and cons, operating principle and types. It will be interesting to look at a photo gallery of examples of installing such devices in the interior.
Fundamentally, such devices can be divided into 6 main types:
- For ;
- For ;
- entrance lighting fixtures;
- phytolamps that help the development of plants;
- emergency lighting devices;
- LED luminaires for commercial lighting.
Today we will not consider LED devices intended for outdoor lighting, as well as devices for retail premises. But it’s worth dwelling on the other four types in more detail.
LED luminaires for indoor lighting: some features
LED luminaires for indoor lighting can be wall, floor (table) or. The choice depends on the wishes of the owner. They can be either linear, built-in or overhead. Such devices are installed in an apartment or on landings and can be equipped with motion, sound, time sensors or photocells that automatically turn the light on and off depending on natural light.
LED phytolights for lighting plants and their purpose
Scientists have proven that if the color of the LEDs in the phyto lamp is correctly selected (different plants require their own), then you can increase the yield or increase the frequency of flowering. This is actively used by farmers and flower growers.
Very important! If you install a phytolight that doesn’t match the color scheme, you can simply ruin the plant. It stops developing normally, bearing fruit or blooming.
LED luminaires for emergency lighting: areas of application
The difference between these devices and others is that they are less bright. Emergency lighting is used to make it possible to move around in the room at night, but at the same time the light should not interfere. It connects to a separate line, which allows you to easily navigate through dark corridors if the main lighting fails. This includes “ENTRANCE” signs above doorways and signs indicating the direction of evacuation in case of fire. They are usually not connected to the public or emergency network. Instead, battery-powered devices are used that continue to operate even if the main and backup lines burn out.
Operating principle and design of LED lamps
The main difference between LED devices and fluorescent lamps for indoor lighting is the absence of an electronic ballast. Instead of an electronic control unit, a diode bridge is installed here, acting as a rectifier. Today, the manufacturer offers LED lighting elements with various types of bases, which makes it easy to replace outdated fluorescent lighting with LEDs.
Important! If replacing incandescent lamps with LED elements is simple, then a fluorescent lamp will have to be upgraded.
Light diodes: advantages and disadvantages of application
Speaking about positive and negative qualities, we note that there are many more of the former. Let's figure out what attracts the buyer to:
- Economical. This is perhaps the main thing that the consumer pays attention to. With the same luminous flux, LED lamps consume several times less electricity than fluorescent lamps, not to mention halogen elements or incandescent lamps.
- Durability. In this parameter, LED devices leave no chance for other types of lighting devices.
- Easy to recycle. Unlike fluorescent lamps, LEDs do not require special handling and are disposed of as normal household waste.
- Strength. Such lighting devices are quite difficult to break or damage.
- Color spectrum. Light diodes have a huge number of colors and shades.
- Resistant to voltage surges. Such devices operate even when the mains voltage drops to 13 V.
If we talk about the disadvantages, we will only note the high cost. However, today it is noticeable how it is decreasing, which means we can hope that in the near future this drawback will be eliminated.
Important! One of the minor disadvantages is the degradation of light diodes, as a result of which the lamp dims over time, however, a similar problem is also inherent in fluorescent lamps - you cannot go against the laws of physics.
Technical characteristics of LED devices that you should pay attention to
The main characteristics that you should pay attention to when purchasing an LED lamp are the following:
- light flow– this parameter allows you to determine how bright the lighting will be;
- power– one of the parameters that affects the strength of the luminous flux, measured in watts (W);
- supply voltage and frequency– parameters that allow you to determine whether the device can be used on a particular network. For indoor lighting choose 24, 36 or 220 V;
- Colorful temperature– the light emitted by the device can be warm, neutral, cold or intermediate between the main temperatures;
- scattering angle– allows you to determine whether the lamp will be a point lamp (directional), or whether the light will be distributed over a large area;
- opportunity– an important parameter if you plan to soften or dim the lighting;
Important! Using a dimmer (a special rheostat-regulator) will be a good solution for a bedroom or living room. However, you should understand that if you purchase regular LED lights, this device will not work.
- ripple factor– a parameter that may not be paid much attention to. All modern LED lamps operate with pulsation, invisible to the human eye. If you need to check the lamp according to this parameter, you can point your mobile phone camera at it - the pulsation will be clearly noticeable;
- Operating temperature range– allows you to determine the possibility of installing the lamp in other rooms with high or low temperatures;
- color rendering index– it means that there is no distortion of the color of objects on which the light from the device falls. An indicator of 100% is considered ideal, but such lamps do not yet exist for sale;
- degree of protection against moisture and dust– the parameter is indicated by the index “IP”. The higher it is, the better the device is protected.
Technical characteristics must be taken into account not only because of the possibility of using the device in a particular environment. They directly affect the cost of devices. The higher they are, the (correspondingly) the higher the price.
Types of overhead LED lamps for interior lighting
There are two main types of LED devices, depending on the type of their location. Among them are directional (spot) and wall-ceiling LED lamps. Which type to install in a particular case depends on the lighting requirements. Directional lighting devices will help to delimit the space of the room into light ones and separate the sleeping area, while wall-ceiling ones, which provide more diffused light, will be a good solution.
They can be round, rectangular or square in shape - the choice here depends on the design of the room. But for the nursery you can choose an unusual shape (soccer ball, fish or princess castle). However, you should understand that directional light is unlikely to be suitable for a nursery. Here, a soft and evenly diffused light flux is more acceptable.
It is important to know! The dispersion angle does not depend in any way on the shape of the lamp. This parameter provides the type of light diodes installed in the lamp. This means that for any interior you can choose a device of various shapes with the angle that is necessary.
Recessed LED luminaires: areas of application and installation nuances
Such LED lamps are intended for suspended or suspended ceilings. Here you can divide it into:
- spot LED devices;
- linear LED luminaires for basic lighting.
If we talk about LED furniture lamps, they can be compared to ceiling spotlights. Moreover, they are often interchangeable and have the same diameter. But linear devices are different. Their power is higher, and their shape is (usually) rectangular. Let's consider one of these devices - an LED lamp " PromLed T-LINE v2.0-40-1000" Here are its characteristics.
| Characteristics | Dimensions | ||
| Power, W | 40 | Dimensions, mm | 1040×85×70 |
| IP class | 67 | Weight, kg | 2,5 |
| Luminous flux, lm | 4600 | Packaging dimensions | |
| Color temp., K | 3000, 4500, 6500 | Dimensions, mm | 1060×150×100 |
| LEDs | Bridgelux | Quantity per package, pcs | 2 |
| Service life, h | 50000 | Gross weight, kg | 8 |
As you can see, this LED device has a protection class of IP67, which means not only complete protection from dust, but also the ability to immerse the device in water to a depth of no more than a meter without compromising performance.
As for , their protection class is usually low. This is due to the fact that cabinet furniture is located in dry, warm rooms, and the need for high protection is not required.
Important! When choosing ceiling spotlights, you should pay attention to the planned operating conditions. For the bathroom you need to buy splash-proof LED lights. Otherwise, there is a danger of a short circuit in a humid environment, and, as a result, the wiring will burn out or even electrocute a person, which is dangerous to health and life.

LED lamps with photocell and motion sensor
Surface-mounted LED lamps for interior lighting of entrances are also equipped with photocells that close the circuit and supply voltage in the absence of natural light. This helps to significantly reduce energy costs and extend the life of lighting fixtures. Let's figure out how they work.
At night, the photocell closes part of the circuit and supplies voltage to the LED lamp. However, there is another node in the circuit that prevents the LEDs from turning on. If a person enters the entrance, the motion sensor is triggered, the circuit is completely closed, and voltage is supplied to the light diodes. After a certain time after the movement disappears, this sensor again “cuts off” the power supply, and the LED lamp goes out. During the day, the photocell is constantly open, and no voltage is supplied to the motion sensor.
It turns out that most of the time the LEDs are inoperative, which affects their service life. And although the energy consumption of LED lamps is low, such schemes further reduce it.
Rechargeable LED emergency lighting: what are they?
Another interesting option is LED emergency lighting lamps with a battery. These are used to indicate emergency and main exits, and signs indicating the direction of evacuation in case of fire, but sometimes they are also installed as regular emergency lighting. The principle of their work is as follows.
The device is connected to the network, power is supplied to the LED elements, simultaneously charging the built-in batteries. If an emergency occurs (a fire with wiring burning out, a short circuit or an accident at a substation) and the voltage is cut off, the batteries come into operation and the lighting continues to operate normally for some time. The duration of operation of the LED lamp depends on the battery capacity and the power consumed by the LEDs and is indicated in the technical documentation of the device.
Good to know! Installing such devices in an apartment is unprofitable due to its high cost. Although today there are cheaper LED lamps on sale with an E27 base and a built-in battery, the charge of which lasts for 2-3 hours of continuous operation. But they are offered (mostly) by Chinese stores. Such a device will cost the buyer 300–600 rubles.
Photo gallery of mounted LED lamps in the interior
For many, the question of how to place LED lamps in a room is difficult. However, this is only the first impression. You just need to show a little imagination, and your interior will sparkle with new colors. The photos presented below will suggest a specific idea to some, while others will be prompted by an idea, developing which, you can add a fresh spirit to the design of your living space. Let's start our review of examples of LED lamps with photos of living room interiors.
The organization of interior lighting deserves special attention. The comfort of being in the room depends on this. You can provide sufficient luminous flux and reduce energy costs by installing incandescent lamps for indoor lighting instead of conventional ones. We invite you to get acquainted with these products, their features, characteristics and types.
They operate on four batteries, providing sufficient illumination of selected areas. Batteries should be replaced every 2.5–3 months. Most models allow you to adjust the brightness of the lighting, motion sensitivity and the time after which the device turns off. Most often, such devices are installed on stairs, in hallways, dressing rooms, long dark rooms, and storerooms. Sometimes they are used as a source of emergency lighting.
Rechargeable LED lamps - creating emergency lighting
When an emergency occurs, power cuts often occur. With the help of LED emergency lighting lamps with a battery, sufficient illumination of premises is ensured for the evacuation of people.
Attention! The power supply is charged from the network when the power supply system is operating in normal mode.
Manufacturers offer rechargeable LED emergency lighting lamps of the following types:
- Non-permanent action. They come into operation only when the main power supply is interrupted. Capable of working for 1–4 hours depending on the capacity of the installed battery. In standby mode, the built-in power supply is recharged from the network.
- Permanent action. After a power outage, the lamps begin to operate automatically on battery power. They can be used not only as an emergency power source, but also as the main one if the power in the building is often cut off.
- Combined. They include several lamps. Some operate exclusively from the network, others from the built-in power supply when the power supply is turned off.
The emergency power supply is mounted directly into the housing of the LED lamp. If there is not enough free space, you can choose a smaller battery or provide a separate case to accommodate the power supply.
Today, LED lamps for indoor lighting are used quite widely due to their efficiency and quality of light. But in order to organize quality lighting in your home, you need to know what these lamps are, where they are located and what they are used for. In this article you will get acquainted with lamps of this type and learn how to use them correctly.
Features of LED lighting
Indoor LED lighting has become widespread recently. What is the reason for such popularity? First of all, this is, of course, high efficiency. The electricity consumption of a semiconductor device is 8-9 times lower compared to incandescent lamps with the same light flux created. Even fluorescent “energy-saving” lamps are two times behind LEDs in energy efficiency.
LED light source is 8-9 times more economical than an incandescent lamp
The next indisputable advantage of semiconductors over other light sources is their durability. The time between failures of an LED lighting device ranges from 10 to 30 thousand hours, while the Ilyich light bulb lasts only 1 thousand hours.
Don't forget about the color temperature for indoor lighting. Thanks to special additives, semiconductors can shine not only with any light - from warm to cold, but also with any color. This is very useful when organizing not only interior lighting, but also decorative lighting.
Using indoor LED lights for decorative lighting The next plus is the low operating temperature. Indoor LED light sources rarely heat up to temperatures above 60-70 degrees, while the same incandescent lamps can heat up to 90-100 degrees, and their halogen counterparts - up to 250 degrees Celsius. This allows the use of semiconductor interior illuminators almost everywhere: from shop windows and wall sconces to embedding in suspended ceilings, which are catastrophically afraid of overheating.
Of course, LEDs also have their drawbacks: they are still quite expensive. But the development of technology promises to cope with this problem in the near future, although even today the high price of LED equipment is quickly paid off by its efficiency and long service life.
What characteristics of LED devices should you pay attention to when choosing
When choosing an indoor LED lamp, you usually focus on its power and luminous flux. Less often on color temperature and lighting direction (coverage angle). All this is undoubtedly true, but when buying a lighting device, one cannot neglect many seemingly unimportant details. Mounting method, primary purpose, appearance, design, additional functions - all these are also important criteria, taking into account which you will be able to organize lighting at the highest aesthetic and quality level. That is why I focused the article on these “unimportant” details of LED lights.
Types of ceiling lamps
LED interior lights placed on the ceiling can have not only different power and coverage angle, but also design. The main types of structures include:
- Built-in.
- Invoices.
Built-in
Internal devices of this type are completely recessed into the interceiling space; only the light-emitting part remains outside - protective glass and sometimes decorative edging.
Design of a recessed spotlight
The advantage of this design is that the device does not take up useful space and does not change the interior of the room. Of particular interest are lamps with a rotating optical system, which allows you to change the direction of light with a simple movement of the hand.
Recessed spotlight with rotating optical system Since LEDs do not heat up to high temperatures, like, say, halogen lamps, such indoor lamps can be built not only into hard overhead lamps, but also into suspended ceilings that are afraid of overheating. The coverage angle of recessed luminaires may vary, but usually does not exceed 180 degrees. The sizes of devices are also not regulated: from miniature point devices to raster devices with a large light-emitting area - up to a square meter or more.
Examples of using indoor recessed LED luminaires Invoices
Overhead lamps for interior lighting, as you might guess from their name, are mounted directly on the ceiling. The body of such a lamp is located outside, but usually it is small in height and does not take up very much usable space. Like built-in, surface-mounted lights are available in different sizes. They can be point, diffuse light and raster. There are models with a rotating optical system.
Rotating spot, diffused light and raster surface-mounted luminaires The advantages of the overhead structure include simple installation. Unlike built-in ones, surface-mounted devices can be installed even on a solid concrete surface.
Linear
A linear lamp has the form of a narrow long strip that glows along its entire length. A classic example of a linear lamp from Soviet times is a lamp with a linear fluorescent tube (LDS). Modern semiconductor devices use LEDs instead of LDS, but the appearance of the illuminator has remained virtually unchanged. The scattering angle of linear lighting fixtures depends on the design, installation method, the presence of reflectors, diffusers and is usually 100-180 degrees.
Based on the installation method, all LED linear illuminators existing today can be divided into three classes:
- Built-in.
- Invoices.
- Hanging.
LED linear luminaire and its design We discussed the first two types above, the latter is mounted on pendants of one length or another, similar to ordinary ceiling chandeliers for the home. Thanks to their design, linear devices allow you to organize lighting that is inaccessible to other light sources. For example, divide the room into zones or create shadowless lighting for the entire room. In addition, suspended structures are not only light sources, but also an original piece of furniture.
Examples of using linear luminaires of different types Modern industry produces not only ready-made linear LED lamps, but also special linear LED lamps, the dimensions and base type of which coincide with the dimensions and base of a conventional LDS fluorescent tube. This solution allows you to replace a fluorescent lamp with an LED lamp without altering the lamp itself. You can read more about this replacement in.
T8 LED lamp for direct replacement of fluorescent lamp For Armstrong ceilings
This type of lamps deserves special attention, since it is specially designed for installation in Armstrong panel suspended ceilings, widely used in public spaces.
Construction and appearance of the Armstrong ceiling The peculiarity of the lamp is that its dimensions coincide with the size of a standard ceiling panel. Thus, to organize lighting, it is enough to remove any ceiling panel and install a lamp in its place. Moreover, this can be done anywhere on the ceiling.
Appearance of the Armstrong lamp and its use Wall lamps and sconces
In addition to traditional ceiling lamps, wall illuminators, both spot and diffused light, are very often used to organize interior lighting. They can be used for local, local lighting and decorative lighting.
Example of decorative lighting using interior wall lights Interior lamps, which are part of the interior and serve not only for lighting, but also for decorative purposes (as decoration), are usually called sconces. Such devices are indispensable for internal local soft or spot lighting of certain areas and are an excellent addition to both the main lighting and the interior.
Such LED wall lamps fit perfectly into the interior and are not only light sources, but also decoration
Battery-powered luminaires for emergency lighting
Autonomous indoor luminaires are mainly used for emergency lighting of particularly critical technical facilities, where interruptions in lighting are unacceptable. Nevertheless, they are quite widely used in everyday life for emergency lighting of rooms where the power supply leaves much to be desired.
Simple and low-cost models of internal emergency light sources are equipped with their own batteries - galvanic batteries (batteries) or batteries. Such devices are turned on manually as needed. Due to their exceptional energy efficiency, using LED lamps as interior emergency lamps is an ideal option. Even ordinary batteries can last an LED illuminator for tens or hundreds of hours of continuous operation.
More complex devices are powered by batteries and can turn on automatically when the mains voltage disappears. Moreover, as long as there is electricity in the network, such a lamp independently charges its battery.
Another type of emergency lamps is with a battery and its own solar panel. During the day, the device stores energy in the battery and uses it as needed.

With motion and light sensor
Models with built-in motion and light sensors belong to a special category of indoor illuminators and, in fact, are automatic devices. The first is activated as soon as a moving object enters the field of view of a special sensor. The second one turns on when ambient light is low and automatically turns off if the lighting at the site reaches normal levels.
Motion-triggered lighting devices primarily use thermal (infrared) sensors that can respond to the appearance of a person from a distance of up to 15-20 m. This is quite enough to work in most domestic premises: storerooms, staircases, corridors, local illumination of workplaces . Devices of this type can be powered either from the mains or from a built-in battery.
Internal lighting devices that are triggered by the level of illumination are used primarily as duty lights to illuminate particularly critical places (staircases, main entrances, entrances), but can also be used in residential premises. For example, as night lights or interior decorative lighting. Their sensitive element is a photosensor, which causes the lamp to turn on if the external illumination is below a predetermined level.
