Light to illuminate the equipment inside. LED luminaires for indoor lighting and solving other problems: an overview of the proposals of the modern market with comments

When planning the lighting of a living space, one should be guided by the fact that the luminaires should emit uniform light, use energy efficiently and have a long service life. It is to these requirements that indoor LED luminaires . In addition, 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 indoor lighting of residential and industrial premises is due to a number of exceptional qualities:

• economic efficiency - LED lamp consumes 10 times less electricity than incandescent lamps of similar brightness, and 40% more economical than fluorescent light sources;

Device

• service life - LED-lamps are able to function for 11 years of continuous operation, which exceeds the indicator of a conventional lamp by 100 times;
• strength and safety - due to the absence of filaments and glass cases, LED lamps are resistant to shocks, vibrations: even a fall from a height of one and a half meters will not affect the working parameters of the lamp. The lack of heat makes them fireproof;
• silent operation, no UV radiation - LED lighting devices emit a smooth, flicker-free light, unlike fluorescent lamps, the glow of which is accompanied by clicks, squeaks, a one-time shutdown, as well as the generation of ultraviolet radiation;
• maintainability and disposal - the lamps can be easily replaced by soldering, and the 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 modifications of LEDs with light scattering 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 suspended and built-in appliances. In addition, the design of the lamp does not require the installation of additional devices (electronic ballasts).

Such a number of advantages allows the use of LED lamps in lighting living rooms and premises. technical purpose: bathrooms, pantries, dressing rooms, corridors, flights of stairs, as well as in public buildings: hospitals, offices, libraries and other organizations.

Types of overhead LED lamps for indoor lighting

The main feature of overhead fixtures is that you can plan their installation not only at the stage of repair work, but also after this process is completed. Such lighting would also be an excellent solution for those who are considering using it to illuminate furniture or accent lighting of individual areas of the room.

According to the method of attachment to the surface, overhead wall and ceiling lamps are distinguished. 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, echoing in style with additional lighting devices;
• for the hallway - taking into account the configuration of the room, you can use one or more lamps of a round or rectangular shape 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 lamps with small nightlights;
• for a study - overhead lamps for this room are selected in a seasoned design, complete with;
• for kitchens, baths and bathrooms - they use devices of various shapes with sealed shades, the most suitable for design;
• for utility rooms - here you can use square, rectangular or round models, with fastening both to the ceiling and to the wall.

Helpful advice! Applicationsurface-mounted LED luminaires 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, the design of some of them is made in an anti-vandal design, which allows them to be installed in rooms with difficult conditions, including entrances or other fairly passable places.

LED luminaires for indoor lighting: recessed models

LED lights 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 for interior decoration in any color options.

Recessed LED spotlights

Spot lighting is one of the most popular ways to transform the interior through lighting. The design of spotlights is a housing hidden in the surface, and the front part, consisting of a light bulb, diffuser, reflector and other decorative details. Their main advantages are compactness, rigor and versatility of use.

Available LED recessed luminaires round , square and rectangular shape. According to the type of case, thin and standard models are distinguished. They have several glow colors, including cool, warm, day white and multi-color. In addition, models are produced that differ in the angle of illumination: with a narrow (up to 45 degrees) and a wide beam.

Such devices are mounted using special spring brackets. To do this, holes of a smaller diameter are made in the surface than the front part of the spotlight, which allows you to hide the mounting gap. After connecting the wires, the brackets are pulled together to the device and the case is inserted into the hole. Thanks to this easy way mounts, spotlights are easy to install and remove.

Helpful advice! When choosing a point model, pay attention to the fasteners: the material of the brackets must be strong in order to withstand 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 the best suited for the lighting design of ceilings, niches, arches, beams, as well as decorative elements. There are models of lamps that have a swivel design. By turning their movable part around the 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 power consumption, LED lamps are built into cabinet furniture, placing them both inside and outside. Such lighting can be endowed with additional options: switching on when opening a drawer or cabinet door, highlighting the contents of dressing rooms, creating a direction of the 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 in 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 of the working surface of the table, it is more cost-effective to purchase a system of five lighting fixtures, which includes mounting wires, a converter and a power cord. Ideal for use in closets and closets 12 volt led lamp with side button. Their standard length is from 25 to 60 cm. It is possible to order a product up to 1 m long.

Furniture lighting at times 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 embossed.

Helpful advice! When choosing fixtures for furniture lighting, it is necessary to take into account the purpose of the room where the furniture is located. If it is a kitchen or bathroom, you should use lamps with special protection against 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. With the help of connecting elements, they can be mounted both in a single line and 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 is an aluminum case, an LED board and a plastic diffuser.

The main difference between such light sources and luminescent counterparts is that area lighting with LED lamps 3 times less electricity is required. 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 luminescence.

Linear lighting systems turn on instantly, and the number of on / off does not affect the duration of use of lighting fixtures. Linear lighting structures are used for indoor lighting of residential, office, industrial premises, workshops, warehouses and agricultural facilities: greenhouses, poultry houses, etc.

LED lamps with motion and light sensor

There are situations when it is necessary to use the backlight in places where it is difficult to supply power or intermittent lighting is required, which would function only if there were people in this area. For these purposes, the use LED lamps with a motion sensor on batteries.

Such devices are powered by 4 batteries (AAA batteries) and have 6 LEDs in their device, which are capable of creating quite powerful lighting. A feature of lamps with a motion sensor is the duration of operation (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.

The main parameters of lighting fixtures with a motion sensor:

• operating voltage - 3V;
• the duration of the LEDs in the "failure" mode - over 80,000 hours;
• setting the brightness of the glow;
• setting of various turn-off 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 state.

The scope of use of this kind of lamps includes the lighting of flights of stairs, dark corridors, halls, pantries, dressing rooms. Such lamps are appropriate in homes where families with children live: a child at night can go to the kitchen or toilet room without fear. In addition, such lighting fixtures can serve as emergency lighting.

With motion sensor

Rechargeable LED Lights: Emergency Lighting

Emergency lighting devices are used in emergency conditions for the evacuation of people or in cases where the mains voltage is turned off. Main Feature LED emergency lighting fixtures 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 the normal mode.

There are several modifications emergency shutdown LED rechargeable lamps:

• non-permanent action - these devices work only when the main power is turned off. When voltage is applied 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 - in the event of a power outage, such lamps automatically switch to offline mode battery operation. This allows them to be used not only as emergency, but also as lighting for rooms where there is a frequent power outage;
• combined - such devices have a system of several lamps, some of which work only from the network in the presence of voltage, others - only from the power supply in the absence of electricity.

Emergency power supply units for LED lamps can be built into their body. If free space in the luminaire housing is limited, it is necessary to provide smaller battery models or install the power supply in an additional independent housing.

Helpful advice! When using emergency luminaires with a battery, consider temperature regime their operation, since power supplies are quite sensitive to temperature changes.

The main application of emergency lighting is public places: shopping centers, administrative buildings, childcare facilities, hospitals, sports complexes and other facilities.

LED lamps Armstrong: lighting prices

Taking into account the popularity of Armstrong suspended ceilings in administrative, industrial and commercial premises, lighting manufacturers have developed models of LED luminaires that are built into the ceiling structure without violating the integrity of the surface. Such lighting devices are easy to install and significantly save energy consumption.

The dimensions of the Armstrong ceiling fixtures are identical standard sizes 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. According to the brightness of the luminous flux, LED lamps are guaranteed to replace two conventional fluorescent devices.

An important role is played by the environmental friendliness of LED lamps: unlike fluorescent counterparts, they do not contain mercury. In addition, when one of the lamps of the fluorescent design fails, the lighting device begins to emit a flashing light, which adversely affects the vision of people in the room. If the mains voltage is unstable, fluorescent lamps must be changed frequently.

The price of the LED lamp Armstrong 600x600 mm produced by Novy Svet (Russia) is 1100 rubles. The lighting device with a power of 39 W is designed for a supply voltage of 220V, weighs 2.5 kg and has a built-in design. Tall LED power factor (0.9) contributes to the operation of the lighting structure without energy loss.

The cost of Armstrong fixtures depends on the number of fixtures purchased. How large quantity 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 covered by a manufacturer's warranty.

with incandescent lamps are gradually becoming a thing of the past, giving way to more high-tech ones. This is not surprising, because light diodes durable and economical. The scope of their application is diverse - from to the automotive industry. Today we will talk about what LED lamps are for indoor lighting, 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.

Basically, such devices can be divided into 6 main types:

• for ;
• for ;
• driveway lighting fixtures;
• phytolamps that help the development of plants;
• emergency lighting devices;
• LED lighting fixtures for commercial lighting.

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

LED lamps for indoor lighting: some features

LED lamps for indoor lighting are 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 landings and can be equipped with motion, sound, time sensors or photocells that automatically turn on and off the light depending on natural light.

LED phytolamps 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 phytolamp that is not suitable for the color scheme, you can simply ruin the plant. It ceases to develop normally, bear fruit or bloom.

LED luminaires for emergency lighting: applications

Differences of these devices from the rest in the lower brightness. 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 is connected to a separate line, which makes it easy to navigate through dark corridors in case of failure of the main lighting. This includes “ENTRY” signs above doorways and evacuation direction signs in case of fire. They are usually not connected to a public or emergency network. Instead, battery devices are used that continue to work even in the event of a fire in 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 an EPRU, a diode bridge is installed here, which acts as a rectifier. Today, the manufacturer offers LED lighting elements with various types plinths, which makes it easy to replace already outdated fluorescent lighting with LEDs.

Important! If replacing incandescent lamps with LED elements is simple, then the 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 much more of the former. Let's figure out what attracts the 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 chance for other types of lighting devices.
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 devices are quite difficult to break or damage.
5. Color spectrum. Light diodes have great amount 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, we note only the high cost. However, today it is noticeable how it is decreasing, which means that we can hope that this shortcoming will be eliminated in the near future.

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 - it will not work 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 buying a lamp with LEDs 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;
• Colorful temperature- the light emitted by the device can be warm, neutral, cold or intermediate between the main temperatures;
• dispersion angle- allows you to determine whether the lamp will be a point (directional), or the light will be distributed over a large area;
• opportunity – important parameter if mitigation is planned, dim lighting;

Important! Using a dimmer (a 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 lamps, this device will not work.

• ripple factor- a parameter that can not be paid much attention. All modern LED lamps operate with a pulsation that is imperceptible human eye. If you need to check the lamp according to this parameter, you can point the camera at it mobile phone- the pulsation will be clearly noticeable;
• 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 for sale;
• degree of protection against moisture and dust– the parameter is denoted 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 (respectively) the higher the price.

Types of overhead LED lamps for indoor 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 requirements for lighting. Directional lighting devices will help to delimit the space of the room into light ones, separate the sleeping area, and wall-ceiling ones, which give 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 a nursery, you can choose an unusual shape (soccer ball, fish or princess castle). However, it should be understood that directional light for a nursery is hardly suitable. Here, a soft and evenly diffused light flux is more acceptable.

It is important to know! The scattering angle does not depend on the shape of the lamp. This parameter provides the type of light diodes installed in the lamp. So, for any interior, you can choose a device of various shapes with the angle that is needed.

Recessed LED luminaires: applications and installation nuances

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

• spot LED devices;
• linear LED luminaires for the main lighting.

If we talk about furniture LED-lamps, then they can be compared with spot ceiling lights. However, they are often interchangeable and have the same diameter. But linear devices are different. Their power is higher, and the shape is (more often) rectangular. Consider one of these devices - LED lamp " PromLed T-LINE v2.0-40-1000". Here are its characteristics.

Specifications		Dimensions
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	Quantity in a package, 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 against dust, but also the possibility of immersing 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 LED-lights with splash protection. Otherwise, there is a danger of a short circuit in a humid environment, and, as a result, burning out the wiring or even injuring a person. electric shock which is dangerous to health and life.

LED lamps with photocell and motion sensor

Overhead 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 see how they work.

At night, a 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 applied to the light diodes. Across certain time after the disappearance of movement, 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 applied to the motion sensor.

It turns out that most of the time the LEDs are in a non-working state, which affects their service life. 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 LED emergency lighting with a battery. 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 burning out of the wiring, short circuit or accident at the substation) and a power outage, the batteries come into operation, the lighting continues to work in the normal mode for some more time. The duration of the 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 the high cost. Although today there are cheaper LED lamps with an E27 base and a built-in battery on sale, the charge of which is enough 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 arrange LED lamps in a room is complicated. 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 below will suggest a specific idea to some, while others will suggest an idea, having developed which, you can bring a fresh stream into the design of a living space. Let's start the review of examples of LED lamps with photos of living room interiors.

Today, LED lamps for indoor lighting are used quite widely due to their efficiency and quality of light. But in order to organize quality in the house, you need to know what these lamps are, where they are placed and what they are used for. In this article, you will get acquainted with the lamps of this type and learn how to use them correctly.

Features of LED Lighting

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

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

The next indisputable advantage of semiconductors over other light sources is their durability. The time between failures of an LED lighting device is from 10 to 30 thousand hours, while Ilyich's light bulb lasts only 1 thousand hours.

Do not 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 in organizing not only indoor lighting, but also decorative lighting.

Use of indoor LED illuminators for decorative lighting

The next plus is the low operating temperature. Internal LED light sources rarely heat up to temperatures above 60-70 degrees, while the same incandescent lamps can warm up to 90-100 degrees, and their halogen counterparts - up to 250 degrees Celsius. This allows the use of semiconductor indoor lighting almost everywhere: from shop windows and wall sconces to embedding in stretch ceilings, which are catastrophically afraid of overheating.

There are, of course, LEDs and 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 with its economy and long service life.

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

When choosing an indoor LED lamp, they usually focus on its power and luminous flux. Less often on color temperature and lighting directionality (coverage angle). All this is undoubtedly true, but when buying a lighting fixture, one should not neglect a lot of seemingly unimportant details. Mounting method, primary purpose, appearance, design, additional functions- all these are also important criteria, taking into account which you can organize lighting at the highest aesthetic and quality levels. That is why I focused the article on these "unimportant" details of LED illuminators.

Types of ceiling lights

LED interior illuminators placed on the ceiling can have not only different power and coverage angle, but also design. The main types of structures include:

1. Embedded.
2. Overhead.

Embedded

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.

Recessed spot light design

The advantage of this design is that the device does not occupy usable 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.

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

Application examples of indoor recessed LED luminaires

Overhead

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

Swivel spot, diffused light and raster overhead lamps

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

Linear

The linear lamp has the form of a narrow long bar that glows along its entire length. A classic example of a Soviet-era linear luminaire is an illuminator with a linear fluorescent tube (LDS). In modern semiconductor devices, LEDs are used instead of LDS, but the appearance of the illuminator has remained practically 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.

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

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

LED linear lamp and its design

We have analyzed the first two types above, the latter is mounted on suspensions of one length or another, like ordinary ceiling chandeliers for the home. Due 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 of the entire room. In addition, suspended structures are not only sources of light, but also an original piece of furniture.

Examples of using linear fixtures of different types

Modern industry produces not only ready-made linear LED lamps, but also special linear led lamps, in which the dimensions and type of base coincide with the dimensions and base of a conventional LDS fluorescent tube. This solution allows you to replace a fluorescent lamp with an LED one without altering the lamp 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, widely used in public areas.

The peculiarity of the luminaire 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. And you can do it anywhere on the ceiling.

Wall lamps and sconces

In addition to traditional ceiling lamps, wall lamps, both spot and diffused light, are often used to organize indoor lighting. They can be used for local, local lighting and decorative lighting.

Example of decorative lighting with indoor wall lights

Indoor 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 wall LED lamps fit perfectly into the interior and are not only sources of light, but also decoration.

Lamps with battery for emergency lighting

Autonomous indoor luminaires are mainly used for emergency lighting of critical technical facilities, where lighting interruptions 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 budget models internal emergency light sources are equipped with their own batteries - galvanic batteries(batteries) or accumulators. Such devices are switched on manually as needed. Due to their exceptional energy efficiency, using LED bulbs as indoor emergency lights is ideal. LED illuminator even ordinary batteries will last for tens and hundreds of hours of continuous operation.

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

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

LED Indoor Emergency Light and Application Example

With motion and light sensor

Models with built-in motion and light sensors belong to a special category of interior lighting and, in fact, are automatic. 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 turns off automatically if the lighting on the object reaches a normal level.

Lighting devices that are triggered by movement mainly 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 household premises: pantries, stairwells, corridors, local illumination of workplaces . Devices of this type can be powered both from the mains and from the built-in battery.

Internal lighting devices, triggered by the level of illumination, are used mainly as standby ones to illuminate especially critical places (stairs, front entrances, porches), but can also be used in residential premises. For example, as nightlights or interior decorative lighting. They have a sensitive element is a photo sensor that causes the lamp to turn on if the ambient light is below a predetermined level.
