WITH Consumers' drive to save energy costs led lighting manufacturers to a compromise decision to launch technologically new products. On sale there are LED lamps for indoor lighting of various types, sizes and modifications for home use.

By 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 turns from electrical energy into visible radiation.

The complete set of each device includes power supplies, special optical devices and elements for heat dissipation. Depending on the installation method and location, the set of work items may also include:

• cables for connecting to a power source;
• docking connectors;
• jumpers and other details for various purposes and configurations.

A variety of design solutions in the design of the body of lamps for a children's room helps to create home coziness and comfortable conditions for leisure and sleep.

Lighting for classrooms and home libraries

The development of the design of home offices or libraries and the selection of the necessary lighting is always challenging task for designers. Competent selection of lighting fixtures increases the efficiency of using such rooms and makes the premises comfortable.

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 screen or polished. Various types of LED indoor luminaires featured on ceilings and walls help create a calm, creative environment in offices and libraries.

Indoor luminaires are LED devices necessary for organizing functional light in living quarters, offices, entrances, on floor aisles and staircases. They can be mounted in corridors, bathrooms, storerooms, household rooms. The popularity of such solutions is due to the presence a large number operational and technical benefits.

Varieties and features of indoor lamps

Devices designed to illuminate the interior space are identified by various criteria. Most often, separation is carried out according to the installation method. According to this criterion, devices are track, overhead and built-in. Each group of lamps has its own characteristics and technical parameters.

Track models are mounted on a bus wire. The latter can be one-, two- or three-phase. The number of phases depends on the number of groups of light sources regulated in offline... They can be turned on / off, rotated, changing the angle of inclination. These characteristics make the devices multifunctional.

Indoor LED lights Xlight in action

Today, LED indoor luminaires are widely used due to their efficiency and light quality. But in order to organize quality in the house, you need to know what these lamps are, where they are located and what they are used for. In this article, you will be introduced to this type of luminaire and how to use it correctly.

Features of LED lighting

Indoor LED luminaires have become widespread in recent years. What is the reason for such popularity? First of all, it is, of course, high efficiency. Electricity consumption by a semiconductor device is 8-9 times lower compared to incandescent lamps with the same generated light flux. Even luminescent "energy saving" lags behind LEDs in energy efficiency by half.

LED light source is 8-9 times more economical than incandescent lamp

The next indisputable advantage of semiconductors over other light sources is their durability. The MTBF of an LED lighting fixture is 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 indoor lighting, but also decorative lighting.

Using indoor LED illuminators 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 incandescent bulbs can heat up to 90-100 degrees, and their halogen counterparts can reach 250 degrees Celsius. This allows the use of semiconductor indoor lighting almost everywhere: from showcases and wall sconces to embedding in stretch ceilings, which are catastrophically afraid of overheating.

Of course, LEDs 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 quickly pays off for its economy and long term service.

What characteristics of led devices you need to pay attention to when choosing

When choosing an indoor LED luminaire, they are usually guided by its power and luminous flux. Less commonly, color temperature and directionality of illumination (angle of coverage). All this is undoubtedly true, but when buying a lighting device, you cannot neglect a lot of seemingly unimportant details. Fastening 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" parts of LED lights.

Types of ceiling lights

Indoor LED lighting fixtures placed on the ceiling can not only have different power and angle of coverage, but also have different designs. The main types of structures are:

1. Embedded.
2. Overhead.

Embedded

Indoor devices of this type are completely recessed into the space between the ceiling, only the light-emitting part remains outside - safety glass and sometimes decorative edging.

Built-in point illuminator design

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 luminaires with a rotary optical system that allows you to change the direction of light with a simple movement of your hand.

Recessed spotlight with swivel optics

Since LEDs do not heat up to a high temperature, like, say, halogen lamps, such indoor luminaires can be built not only into rigid overhead ceilings, but also into stretch ceilings, which are afraid of overheating. The coverage angle of recessed luminaires can vary, but usually does not exceed 180 degrees. The dimensions of the devices are also not regulated: from miniature point devices to raster ones with a large light-emitting area - up to a square meter and more.

Examples of using indoor recessed LED luminaires

Overhead

Overhead luminaires for indoor lighting, as you might guess from their name, are mounted directly on the ceiling. The body of such a luminaire is located outside, but usually it has a small height and does not take up a lot of usable space. Like built-in luminaires, surface-mounted luminaires are available in different sizes. They can be point, scattered light, and raster. There are models with a rotary optical system.

Rotary spot, diffused light and raster surface-mounted luminaires

The advantages of a surface-mounted design include simple installation. Unlike built-in ones, overhead devices can be installed even on a dull concrete surface.

Linear

The linear luminaire looks like a narrow long strip that glows along its entire length. A classic example of a Soviet-era linear luminaire is a linear fluorescent tube (LDS) illuminator. In modern semiconductor devices instead of LDS, LEDs are used, but the appearance of the illuminator has remained practically unchanged. The angle of dispersion of linear lighting fixtures depends on the design, installation method, the presence of reflectors, diffusers and is usually 100-180 degrees.

According to the method of installation, all LED linear illuminators existing today can be divided into three classes:

1. Embedded.
2. Overhead.
3. Suspended.

LED linear luminaire and its design

We discussed the first two types above, the last one is mounted on suspensions of one length or another, like ordinary ceiling chandeliers for the home. Due to their design, linear fixtures allow you to organize lighting that is inaccessible to other light sources. For example, divide the room into zones or create shadow-free 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 different types

Modern industry produces not only ready-made linear LED luminaires, but also special linear led lamp, in which the dimensions and type of base coincide with the dimensions and base of a conventional LDS fluorescent tube. This solution allows replacing a fluorescent lamp with an LED one without altering the luminaire itself. You can read more about such a replacement in.

For armstrong ceilings

This type of luminaire deserves special attention, as it is specially designed for installation in Armstrong panel suspended ceilings, which are widely used in public spaces.

Armstrong ceiling design and appearance

The peculiarity of the luminaire is that its dimensions coincide with the size of a standard ceiling panel. Thus, to organize the lighting, it is enough to remove any ceiling panel and install a luminaire in its place. Moreover, this can be done anywhere on the ceiling.

Wall lights and sconces

In addition to traditional ceiling luminaires, wall luminaires, both point and scattered light, are very often used for organizing indoor lighting. They can be used for spot, spot lighting and decorative lighting.

Example of decorative lighting with indoor wall luminaires

Indoor lamps, which are part of the interior and serve not only for lighting, but also for decorative purposes (as decoration), are called sconces. Such devices are indispensable for indoor local soft or spot illumination 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 a decoration.

Rechargeable luminaires for emergency lighting

Self-contained indoor luminaires are mainly used for emergency lighting of especially critical technical facilities, where interruptions in lighting are unacceptable. Nevertheless, they are quite widely used in everyday life for emergency lighting in rooms where the power supply leaves much to be desired.

Simple and budget models internal emergency light sources are equipped with their own batteries - galvanic batteries (batteries) or rechargeable batteries. Such devices are switched on manually as needed. Due to its exceptional energy efficiency, the use of LED lamps as an internal emergency - ideal. Even ordinary batteries will last tens and hundreds of hours of continuous operation for the LED illuminator.

More sophisticated devices are powered by batteries and can turn on automatically when the mains voltage fails. At the same time, while there is electricity in the network, such a lamp independently charges its battery.

Another type of emergency luminaires - with a battery and their own solar battery... During the day, the device stores energy in the battery and consumes it as needed.

Indoor LED Emergency Light and Case Study

With motion and light sensor

Models with built-in motion and light sensors belong to a special category of indoor lighting 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 turns on when the ambient light is low and automatically turns off if the illumination on the object reaches a normal level.

In motion-triggered lighting devices, mainly thermal (infrared) sensors are used, capable of reacting to the appearance of a person from a distance of up to 15-20 m.This is quite enough for work in most household premises: storerooms, stairwells, corridors, local illumination of workplaces ... Devices of this type can be powered both from the mains and from the built-in battery.

Indoor lighting devices, triggered by the level of illumination, are used mainly as attendants to illuminate especially critical places (stairs, front entrances, entrances), but can also be used in residential premises. For example, as a bedside lamp or interior decorative lighting. Their sensitive element is a photosensor, which makes the lamp turn on if the ambient light is below a predetermined level.

The organization of indoor lighting deserves special attention. The comfort of being in the room depends on this. It is possible to ensure sufficient luminous flux, while reducing energy costs, by installing for indoor lighting instead of conventional incandescent lamps. We offer you to get acquainted with these products, their features, characteristics and types.

They run on four batteries to provide sufficient illumination in selected areas. The 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, storerooms. They are sometimes used as a source of emergency lighting.

Rechargeable LED luminaires - creating emergency lighting

In the event of an emergency, power outages often occur. With the help of LED emergency lighting luminaires with a battery, sufficient illumination of the premises is provided for the evacuation of people.

Attention! The power supply is charged from the mains when the power supply system is operating in normal mode.

Manufacturers offer the following types of rechargeable LED emergency lighting fixtures:

1. Intermittent action... They are switched on only when the main power supply is cut off. Able to work for 1-4 hours, depending on the capacity of the installed battery. In standby mode, the built-in power supply is recharged from the mains.
2. Permanent action... After a power outage, the luminaires start to work automatically on battery power. They can be used not only as an emergency power source, but also as the main one if the electricity in the building is often cut off.
3. Combined... They include several lamps. Some work exclusively from the network, others - from the built-in power supply when the power supply is cut off.

The emergency power supply is mounted directly into the body of the LED luminaire. If there is not enough free space, you can choose a smaller battery or provide a separate case to accommodate the power supply.

with incandescent lamps are gradually becoming a thing of the past, giving way to more high-tech ones. This is not surprising since LEDs are durable and economical. The scope of their application is diverse - from to the automotive industry. Today we will talk about what LED lamps for indoor lighting are, we will analyze their pros and cons, the principle of operation and varieties. It will be interesting to look at the photo gallery of examples of installing such devices in the interior.

In principle, such devices can be divided into 6 main types:

• for ;
• for ;
• driveway lighting devices;
• phytolamps that help plant development;
• emergency lighting devices;
• LED luminaires for commercial lighting.

Today we will not consider LED devices intended for outdoor lighting, as well as devices for commercial premises. But on the other four types it is worth dwelling in more detail.

Indoor LED luminaires: some features

Indoor LED luminaires can be wall, floor (table) or. The choice depends on the wishes of the owner. They can be either linear, embedded or overhead. Such devices are mounted in an apartment or on stairwells and can be equipped with motion, sound, time sensors or photocells that automatically turn on and off the light depending on natural light.

LED phyto-luminaires for plant illumination 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 flowering frequency. This is actively used by farmers and flower growers.

Very important! If you install an unsuitable phyto-lamp in terms of color, you can simply ruin the plant. It ceases to develop normally, bear fruit or bloom.

LED luminaires for emergency lighting: applications

The differences between these devices from the rest are in lower brightness. Emergency lighting is used so that you can 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 dark corridors in the event of a failure of the main lighting. It includes signs "ENTRANCE" above doorways and indicators of the direction of evacuation in the event of a fire. They are usually not connected to a public or emergency network. Are used instead battery devices that continue to work even in the event of a burn out of the wiring of the main and backup lines.

The principle of operation and the device of LED-lamps

The main difference between LED devices and fluorescent lamps for indoor lighting is the absence of an electronic ballast in them. Instead of EPRU, a diode bridge is installed here, which acts as a rectifier. Today the manufacturer offers LED lighting elements with different types sockets, which allows you to easily replace the already outdated fluorescent lighting with LEDs.

Important! If replacing incandescent lamps with LED elements is simple, then the fluorescent lamp will have to be modernized.

Light diodes: advantages and disadvantages of the application

Speaking about positive and negative qualities, we note that there are many more of the former. Let's figure out what attracts a buyer to:

1. Profitability. 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 ones, not to mention halogen elements or incandescent lamps.
2. Durability. According to this parameter, LED devices leave no chances for other types of lighting fixtures.
3. Ease of disposal. Unlike fluorescent lamps, LEDs do not require special handling and are disposed of as normal household waste.
4. Strength. Such lighting fixtures are quite difficult to break or damage.
5. Color spectrum. Light diodes come in a huge variety of colors and shades.
6. Resistant to voltage drops. Such devices work even when the voltage in the network drops to 13 V.

If we talk about the shortcomings, then we note only the high cost. However, today it is noticeable how it is decreasing, which means that one can hope that in the near future this drawback will be eliminated.

Important! One of the minor drawbacks is called the degradation of light diodes, as a result of which the lamp dims over time, however, a similar problem is inherent in fluorescent lamps- you can't go against the laws of physics.

Technical characteristics of LED devices that you should pay attention to

The main characteristics to look out for when buying an LED luminaire are as follows:

• 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 in a particular network. For indoor lighting, choose 24, 36 or 220 V;
• Colour 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 luminaire will be point (directional), or the light will be distributed over a large area;
• possibility- an important parameter if softening, dimming of lighting is planned;

Important! Using a dimmer (special rheostat-regulator) will be a good solution for a bedroom or living room. However, it should be understood that if you purchase conventional LED fixtures, this device will not work.

• ripple factor- a parameter that can be overlooked. All modern LED luminaires operate with a pulsation invisible to the human eye. If you need to check the lamp by this parameter, you can point the camera at it mobile phone- the ripple will be clearly visible;
• Operating temperature range- allows you to determine the possibility of installing a lamp or other rooms with high or low temperatures;
• color rendering index- it means the absence of color distortion of objects on which the light from the device falls. An indicator of 100% is considered ideal, but such lamps do not yet exist on 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 considered 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 (respectively) and higher the price.

Types of surface mounted LED luminaires for indoor lighting

There are two main types of LED devices, depending on the type of their location. Among them are directional (point) 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, separate the sleeping area, and wall-ceiling, giving more diffused light, will be a good solution.

In shape, they can be round, rectangular or square - here the choice depends on the design of the room. But for the nursery you can pick up unusual shape(soccer ball, fish or princess castle). However, it should be understood that a directional light is hardly suitable for a nursery. Here, a soft and uniformly diffused light flux is more acceptable.

It's important to know! The scattering angle does not depend in any way on the shape of the luminaire. This parameter provides the type of LEDs installed in the lamp. This means that for any interior, you can choose a device of various shapes with such an angle that is necessary.

Recessed LED luminaires: applications and installation nuances

Such LED luminaires are intended for suspended or suspended ceilings. Here you can divide into:

• point LED devices;
• linear LED luminaires for main lighting.

If we talk about furniture LED-lamps, then they can be compared with a point ceiling. Moreover, they are often interchangeable and have the same diameter. But linear instruments are different. Their power is higher, and their shape (more often) is rectangular. Let's consider one of such devices - LED lamp " PromLed T-LINE v2.0-40-1000". Here are its characteristics.

Specifications		Dimensions (edit)
Power, W	40	Dimensions, mm	1040 × 85 × 70
IP class	67	Weight, kg	2,5
Luminous flux, lm	4600	Packing dimensions
Color temp., K	3000, 4500, 6500	Dimensions, mm	1060 × 150 × 100
LEDs	Bridgelux	Package quantity, pcs	2
Service life, h	50000	Gross weight, kg	8

As you can see, this LED device has an IP67 protection class, 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 lamps. Otherwise, there is a danger of a short circuit in a humid environment, and, as a result, burnout of the wiring or even injury to a person. electric shock, which is dangerous to health and life.

LED luminaires with photocell and motion sensor

Surface-mounted LED luminaires for interior lighting of entrances are also equipped with photocells, which close the circuit and supply voltage in the absence of natural light. This helps to significantly reduce energy costs and extend the life of the lighting fixtures. Let's figure out how they work.

In the dark, 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 the voltage is applied to the light diodes. After a certain time after the disappearance of the movement, this sensor again "cuts off" the power supply, and the LED lamp goes out. During the day, the photocell is constantly open, and the voltage is not supplied to the motion sensor.

It turns out that most of the time LEDs are inoperative, which affects their lifespan. And although the power consumption of LED lamps is small, such schemes further reduce it.

Rechargeable LED Emergency Lights: What They Are

Another interesting option is the rechargeable LED emergency lighting fixtures. These are used to indicate emergency and main exits, signs with the direction of evacuation in case of fire, but sometimes they are also installed as ordinary emergency lighting. The principle of their work is as follows.

The device is connected to the mains, power is supplied to the LED-elements, simultaneously charging the built-in rechargeable batteries. In the event of an emergency (fire with burnout of the wiring, short circuit or an accident at the substation) and a power outage, the batteries come into operation, the lighting continues to work in normal mode for some time. The operating time 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! The installation of such devices in an apartment is unprofitable due to the high cost. Although today on sale there are cheaper LED lamps with an E27 base and a built-in battery, the charge of which lasts for 2-3 hours of continuous operation. But they offer them (mostly) Chinese shops... 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 arrange LED lights in a room is difficult. However, this is only a first impression. You just need to show a little imagination, and your interior will sparkle with new colors. The photos presented below will prompt some of them with a specific idea, while others will be prompted by an idea, developing which, you can bring a fresh stream to the design of a living space. Let's start an overview of examples of LED lamps with photos of living room interiors.
