Which LED light bulbs are best for an apartment. Parameters for selecting LED bulbs. Which ones are more reliable and durable?

Today, most users of lighting devices give their preference to LED lamps. LED light bulbs for the home are considered the most economical and efficient. However, the cost of such elements is quite decent, especially when it comes to global brands. Manufacturers of LED lamps offer many models based on modern technologies, so the issue of price-quality ratio is always very pressing.

Famous brands

The most expensive are LED bulbs, which are especially popular in Europe. This LED models brands Cree, Osram, Philips. According to statistics, it is these companies that most often produce lamps that top the international ratings, however, in the conditions of the Russian market, some nuances must be taken into account.

Firstly, manufacturers of LED lamps of this level create models only with a voltage of 220V, as in European countries, and 110V, as in the USA. Secondly, most light bulbs use an E26 base. In Russia, the E27 base is more popular. However, we shouldn’t write off the so-called TOP-3, so let’s take a closer look at them.

• The Dutch company Philips produces a wide variety of lighting products. The advantage of their LED bulbs is that they not only save energy, but are also highly environmentally friendly. Therefore, they can be used to illuminate the home for a long time. However, these LED products are considered one of the most expensive.
• The Austrian brand Osram has a lot of distinctive signs. As a result of expert testing, the lamps from this company were recognized as the most energy efficient, and were also noted as products with a high degree of environmental protection and a long service life. The high cost may deter buyers, but these are the best led light bulbs today, so they pay for themselves within a year.
• The CREE company was one of the first to offer innovative powerful LEDs. These new generation LED lamps have a high luminous flux and minimal energy consumption, so they are considered a real alternative halogen light bulb. The company today produces ultra-bright devices in the “High-Brightness” line, as well as powerful “XLamp” LEDs. For the home, the second group of light bulbs is used directly, which includes models with different light directions and brightness. However, lamps with a reddish-yellow glow from this manufacturer are not found in all new model lines.

How do the above LED companies ensure high quality? Firstly, they produce all products only under their own brand. Secondly, each stage of production is subject to constant monitoring. Finally, all these companies produce light bulbs not on an assembly line, but by creating separate departments involved in different processes. This division of labor seriously improves the quality of lamps, because if there is a defect, they will deal with a specific department.

Interestingly, the top ranking of the most popular companies producing LED light bulbs often includes the Gauss brand. Surprisingly, unlike its colleagues, this brand is Russian. The high price of the products is fully justified by the use of unique technologies. LED light bulbs from Gauss are not only economical, but also have an original design and almost do not heat up. They can be safely used at home to complete the look of a modern chandelier and can even be used with a suspended ceiling.

Among the popular foreign companies in the field of lighting technology, Nichia should be noted, which creates light bulbs in Japan. The demand for these products is quite high. The advantages of the brand are low price, high-quality assembly and good efficiency of lamps in operation.

In pursuit of new products, many consumers prefer to buy light bulbs from well-known brands from the most fashionable lines. It is worth noting that the price of such products is often overpriced, and the innovations used are not always what the buyer really needs. Therefore, pay attention to the year of manufacture of LED bulbs. The best lamps, of course, are part of the latest generation of products. Their main advantage is modern and durable LEDs. But sometimes even the largest online stores of European companies organize profitable sales on old light bulbs. They are no worse in quality, and a discount will always be a pleasant bonus in your purchase.

Domestic control

To begin with, it is worth noting that today the market for LED products includes both nominally Russian brands and actually local manufacturers. In the first case, it is important to understand that the creation of light bulbs is carried out in Chinese factories. In such conditions, Russian companies only control the ongoing work, providing the necessary drawings. LED bulbs of similar brands, in principle, have no bad quality, since salary increases directly depend on the level of sales. Also, the advantages of such brands can be considered operational work with consumer complaints and the low cost of lamps. Let's look at which light bulbs in this category you can buy without fear.

• Feron is one of the oldest companies on the Russian market, producing products since 1999. The company has a very wide range of LED light bulbs, and one cannot help but rejoice at the affordable prices. An additional plus is an honest indication of all the characteristics of the lamps on the packaging. The brand also has an official online store, so you can purchase products without leaving your home.
• A major lighting engineering company is Camelion, whose brand is known throughout the world. However, the problem with the products of this brand is the lack of clear markings on the light bulbs. The technical designations for LED lamps are very long, so you will have to understand the need for a particular product in advance. But most of the light bulbs from this company have an original design that allows you to create a wide angle of illumination.
• The Jazzway brand rarely receives negative reviews of its products, which inspires confidence. The company has established itself as a manufacturer of reliable and certified light bulbs. At the same time, you can purchase very powerful and bright models with an E27 base for your home.
• Navigator has been present on the Russian market since 1993 and during this time has rarely let down buyers of LED products. Since 2002, the company has been cooperating with General Electric and Osram, so it is not surprising that Navigator is the leader in sales of General Electric products in Russia. Each light bulb has a clear description, down to the LEDs used in assembly, as well as the necessary documents. I wonder what this company produces LED lamps with filamentous LEDs.
• The Era company also creates very high-quality LED products, but does not always correctly indicate the characteristics of the light bulbs. This is especially important in a situation where the consumer is just moving from incandescent lamps to new generation inventions. Prices for products from this brand are slightly above average.

Among the less popular companies with Chinese scheme assemblies can be noted, for example, “Elektrostandard”, “Ecola”, “Odeon”, “Uniel”, “Start”, “Space”, “Economy”. The advantage of these manufacturers is that they, as a rule, take care of the availability of electronic catalogs on official websites. Brands have interesting models, although sometimes the characteristics of light bulbs may not be sufficient for constant use at home.

It is interesting that it is the conventionally Russian group of manufacturers that occupies the majority of our market for LED products. The products of these brands are extremely popular, and constant demand motivates companies to improve the characteristics of light bulbs. The best-selling are Feron, Navigator, Camelion. In terms of the presence of negative reviews, the leading companies are Cosmos, ASD, and Odeon. The main problem with these brands of light bulbs is the constant burnout of LEDs.

Please note that the best led lamps such manufacturers are not always expensive. They can make products cheaper not by reducing quality, but by promoting more convenient technologies. Therefore, other things being equal, sometimes it makes sense to give preference to models with low cost.

Russian production

Now it’s worth paying attention to truly domestic manufacturers who create LED light bulbs in Russian factories. Many people believe that the level of such products is much better. Here, of course, there are some nuances, but the price-quality ratio of such brands is almost always ideal.

• "Optogan" produces energy-efficient models of light bulbs with very bright diodes. In terms of characteristics, this company is in no way inferior to the leader of the Russian rating - the Gauss company - however, the huge advantage of Optogan is the affordable cost of the lamps. An indicator of the company's production is that many of the concepts of this brand have begun to be used by foreign colleagues.
• SvetaLed also assembles its light bulb models at its own factories using domestic chips. This brand competes well with Osram and Philips. The company's LED lamps have long been considered exemplary, and although the price seems overpriced in comparison with unknown Russian brands, the products pay for themselves very quickly.

There are also lesser-known companies that produce LED products. Of course, buying a light bulb without confidence in its characteristics is sometimes risky, but if the product is needed, for example, not for the home, but for the dacha, it is not worth overpaying once again for the authority of the brand. Therefore, an excellent alternative to the above-mentioned companies is, for example, the Svetlana-Optoelectronics company.

Chinese companies

Purely Chinese brands, as a rule, are little known to Russian buyers, even by ear. In most cases, production remains a secret to consumers, and it is not always clear which country and quality parts were used. Chinese companies rarely follow generally accepted standards, so sometimes LED bulbs can even give off an unpleasant green tint. The advantage of such products is their extremely low cost, but most likely the indicated service life will be many times overestimated.

Of course, in China all these companies have the necessary certificates to operate. Brands such as Ali, DX, MiIntheBox are no longer uncommon in our market, but they are intended exclusively for casual buyers. If you study the quality of products in detail, you can immediately encounter a discrepancy between the specified characteristics and reality. The power of such light bulbs, as a rule, does not exceed 3-5 W.

Unfortunately, there are often cases when products are not only useless, but also dangerous. The fact is that instead of LED drivers, unscrupulous companies place standard ballasts in light bulbs. The result is a flickering light that strains the eyes. That is why it is better to avoid such lamps if you require a product for daily use. If you urgently need to save money when purchasing an LED light bulb, you can choose Maxus products. It also has significant shortcomings, but it gets more laudatory reviews than other Chinese brands.

Model overview

In most cases, ratings of LED light bulbs are compiled either directly by regular users of the products, or by experts based on comparative tests. Understanding how the hierarchy is distributed in the TOP of the best LED lamps helps you make the right choice when purchasing it yourself. So, in terms of price-quality ratio, the following models are the best (not including European companies):

• Among the most popular LED light bulbs with an E27 base and a power of 60 W, the Navigator version comes first. Also suitable for use are lamps from the brands “Wolta”, “Lexman”, “X-Flash”, “IKEA”. In the 75 W power category the "OSRAM" light bulb also appears. At 95 W, the Gauss lamp turns out to be the best.
• LED light bulbs in the form of candles are produced with an E14 or “minion” base. In this group, the best 40W lamps are “Uniel”, “Navigator”, “Lexman”, “Volta”. With a power of 60W, the optimal model is from Gauss. The main thing is not to forget that in in this case You will need an adapter to connect to the E27 socket.
• As for LED bulbs in the shape of a ball, they are also found with a standard base. At 40 W power, good options are offered by Cosmos, Vitoone, and X-Flash. With an E14 base, such lamps can be used in production from Wolta, Lexman, Nanosvet.
• Many consumers also like mirrored LED bulbs. With a minion base they come in 35-40 and 50 W ratings. The first group includes the same brands that produce high-quality ball lamps. In the second category, in addition to the above, there is the “Artpole” brand, which, however, offers light bulbs for more than 300 rubles apiece. Mirror lamps with a regular base are available from the Era brand.
• In such a rating it is impossible not to include LED lamps that replace halogen spotlights. Their peculiarity is narrow beams of light that do not tire the eyes. In this case, the leader is the Kreonix company. The same light bulbs, but with a wide lighting angle, are produced with high quality by X-Flash and Lexman.

In addition to ratings that take into account only the cost and quality of products, there are also lists in which light bulb models are ranked on a different basis. Thus, the luminous efficiency of the lamps, color temperature, power factor and even the warranty period are taken into account.

As statistics show, most often the winner of such studies is the Navigator company, but European brands do not participate due to inflated costs. This company offers an excellent economical replacement for incandescent light bulbs, while most models have a bright design, high color rendering and a long operating time.

Further, a similar rating includes “Uniel” light bulbs, which look great in decorative lamps due to their original and completely unique shapes. It is also worth noting the good performance of the Svetlana-Optoelectronics brand. Models from the Ecolight and Svetovod brands are slightly less effective, but even in this case the consumer receives environmentally friendly and stable LED bulbs.

Electricity has been used for indoor lighting for a very long time. For a long time, only incandescent light bulbs were used in apartments, offices, shops, houses, etc. These small devices are still valued mainly for their fairly powerful stream of light, which also has a natural tint that is pleasant to the eye. However, incandescent light bulbs have several significant disadvantages. First of all, these are high indicators in terms of energy consumption and a short service life. Therefore in lately Other types of lighting fixtures are becoming increasingly popular - economical and durable. The latter include those invented not so long ago LED lamps.

A little history

The LED was first manufactured by famous engineer Nick Holonyak in 1962. The device he designed emitted visible red light. Soon after the appearance of this interesting invention, the American company Monsanto put its production on stream. The first device of this type came off the assembly line in 1968. Monsanto's light bulbs were intended for use primarily digital watch and calculators. For the next few decades, LEDs were used only in industrial and consumer electronics.

220V LED lamps, emitting bright white light and designed to illuminate rooms for various purposes, began to be produced only in 1997. The creator of the first such device was the American Fred Schubert. Nowadays, such devices are already used in many industrial and residential premises.

Main design elements

Modern LED lamps are assembled using the following components:

Base. As in this element, in this case it is intended for screwing the device into the lamp socket.

Drivers in a plastic case with ventilation holes. This unit is designed to convert alternating current into direct current. In addition, its design includes special capacitors necessary for cooling the lamp. Another element is a zener diode, which is used to equalize voltage drops in the network.

Radiator. This unit is made of aluminum and has a very large number ribs It is also needed to cool the LED.

Board made of aluminum. A special thermal paste is applied to the side facing the radiator. About 90% of the heat emitted by the LED is transferred to the board.

Diffuser. give narrowly focused light. This element in their design is intended to diffuse it in order to uniformly illuminate the room.

The LED itself.

As you can see, compared to conventional incandescent lamps, the devices we are considering have a more complex design.

What is LED

Of course, this is the main element in the lamp. Actually, an LED is called a special one that converts electrical energy into light. The main design elements of this device are:

Substrate that conducts current.

An LED crystal placed on it.

A housing that encloses both elements. On one side there are contacts, and on the other there is a lens. Silicone is poured between the latter and the LED crystal.

Aluminum base on which all elements are fixed.

Operating principle

The LED operates thanks to special process recombination of electrons between two contacts with different degrees of conductivity. At the places where the latter emerge, the crystal is doped with an acceptor impurity containing a small number of electrons on one side, and an increased amount on the other. Recombination occurs immediately after the lamp is switched on. As a result, excess energy arises, which is converted into light flux.

Main Features

Owners of houses, offices, shops and apartments, when choosing LED lamps, first of all pay attention to three main parameters:

The degree of heat of the flow. Lamps of this type can produce light of different shades. Devices emitting cold flow are used mainly in public institutions. For apartments and houses, lamps with “warm” light are often chosen. The most popular types, therefore, are the 2700, 3000 and 3300 K models.

Base type. The standard option is considered Models with such a base are suitable for all household lamps. There are also minion LEDs on sale, marked E14.

Device power. As you know, the most popular are 60-100 W incandescent lamps. These indicators correspond to 7-13 W LEDs.

What device should I buy for my apartment?

Thus, the answer to the question is not difficult. The best option for a residential premises there will be a device with an E27 base and a warm heat flux of 2700 K.

As for power, in this case the choice largely depends on what specific purposes the device is intended to be used for. So, for a living room or office, a thirteen-watt E27 LED lamp (analogous to a 100-watt incandescent device) is best suited. For the bedroom it is better to choose a 7-10 W model. The same lamps are suitable for the kitchen and small hallway.



Advantages of devices

So what exactly are the advantages of an LED lamp? Reviews about devices of this type are mostly good. According to consumers, they:

Light emitting diodes (LEDs) are widely used as indicator lights and can be seen on dashboards and billboards, and in the last few years LED home bulbs have become increasingly popular.

The modern consumer is attentive to the ratio of price and quality, especially when it comes to technical innovations. Let's find out whether LED lamps will help you save money and what advantages the use of LED lamps brings.

Characteristics of LED lamps for home

Traditional incandescent lamps, including halogen lamps, are characterized by high energy losses in the form of heat. In an LED, alternating current is converted into direct current with virtually no heating, which makes LED lamps economical and safe. The operating life of an LED lamp can be 30,000–100,000 hours, depending on the technology and operating conditions.

One of the important advantages of LED lamps is the wide choice of light temperatures. Lamps of 2600–3200 K (warm white) and 3700–4200 K (natural white) are optimal for the room. Deviations up or down are perceived as uncomfortable and even oppressive. For an apartment it is recommended to use warm white, but a table lamp for a workplace can be with a natural LED lamp white light- a cool shade of lighting will help you quickly get into a working mood.

LED lamps are stronger than conventional lamps, they can be shaken and dropped without the risk of being shaken or dropped, they will not burst in your hands from too much pressure, and they do not burn out from frequent switching on/off of the light.

High-quality LED lamps do not have the pulsation effect of the light flux. This unpleasant phenomenon, sometimes invisible to the human eye, leads to rapid fatigue. You can check for pulsations using a mobile phone camera. When you point the lens at the pulsating lamp, the image on the screen will blink.

Which LED lamps are best to choose for your home?

The choice of lighting for the home has its own specifics, because most often we spend the dark time of the day here, doing everyday things, and the lamps should provide maximum comfort for long hours.

Power. If you decide to replace conventional lamps with LED ones and don’t know how to choose the power, a simple formula will help you: divide the power of the replaced incandescent lamp by 8.

Voltage. LED lamps operate on a conventional voltage of 220 V, but can also be designed for 110 V.

Number of LEDs in the lamp. Although LEDs do not burn out like regular incandescent bulbs, they do experience aging. The more LEDs provide the required brightness of the lamp, the longer it will last.

Design and shape of the product. LED lamps can be made either in the traditional version with one or another bulb (ball, pear, globe, candle), or in the form of “corn” with LEDs located similar to grains on the cob.

Case materials. Frosted and transparent glass, aluminum, plastic, and ceramics can be used in the manufacture of the LED lamp body. When choosing between glass and plastic lamps, give preference to glass ones - they have higher light transmission rates.

Product protection degree. This indicator is indicated by the letters IP and numbers. For a normal room, IP40 is enough, for a dusty room - IP50.

Base. LED lamps have screw and pin bases. Screw ones are designated by the letter E and numbers indicating the diameter in millimeters. Pins are designated by the letter G and numbers indicating the distance in millimeters between the pins.

• E27 - classic threaded base. Suitable for chandeliers and lamps designed for the use of energy-saving lamps and incandescent lamps.
• E14 is a variation of the E27 base with a smaller diameter. Suitable for many modern lamps. Such a base is usually found in “minion” and “candle” lamps.
• GU5.3, G9 - LED lamps with this base can completely replace halogen lamps.
• GU10 - most often this base is used for installing lamps in kitchen hoods and built-in lamps for illuminating the work surface.
• G4 - base with two “wires” at the end. Typically used in small lamps to illuminate pictures.

Price . High-quality lamps cannot be cheap. Of course, even 500 rubles for a light bulb can be psychologically difficult to pay, not to mention larger sums. However, if you remember about the energy efficiency and service life of LED lamps, this problem will disappear by itself.

Manufacturer . The intensity of the blue spectrum in LED radiation is high, and this factor can negatively affect vision and psychological comfort. The best manufacturers make sure that LED lamps are safe for health, while small nameless ones are not interested in this issue at all. If you want new lamps to work for a long time and help your vision, give preference to high-quality certified products. The manufacturer must be indicated on the packaging.

The search for high-quality LED lamps should begin with the choice of manufacturer, since for unknown companies the characteristics stated on the packaging may not always correspond to reality.

Rating of LED lamp manufacturers

The LED lighting market in Russia is still in its infancy. Our demand for energy-saving lighting devices developed much later than in other countries. Therefore, the share of domestic LED products on the market is small; mainly imported LED lamps are sold. Almost all of the manufacturers listed below have official websites in Russian.

European countries

LED products made in Europe are of high quality, harmless to health, and meet all modern requirements for lighting devices. Of course, this also affects the price.

• Philips . A global brand based in the Netherlands, operating in three main areas: healthcare, lighting solutions and consumer products. LED lamps from this manufacturer can cost 500–1800 rubles; they can be purchased at almost any reputable retail outlet that has a department of electric lighting devices.
• Osram . A German company known throughout the world for over 100 years as a proponent of “intelligent light”. Lamps can be purchased for 400–1600 rubles in specialized lighting stores.
• Foton Lighting . Manufacturing and trading lighting company headquartered in London. Foton Lighting LED lamps cost 400–700 rubles. They are easy to find in online electrical stores.

Japan

Japanese engineers have a reputation as pioneers in many areas of technology, and Japanese attention to detail can rival German. This is why products from the Land of the Rising Sun are so popular all over the world, and LED lamps are no exception.

• Nichia . The high-brightness LEDs produced by this company have long been used in dozens of areas of modern industry, and have recently found their consumers in everyday life. A special feature of Nichia LED lamps is the use of special optical lenses, thanks to which the light is distributed evenly. Prices for lamps from this manufacturer start at 300 rubles.

Russia

Domestic LED products are currently not inferior in quality to European ones, and with the same characteristics they can cost less due to the fact that production facilities are located in Russia.

• Gauss . A wide range of LED products that undergo strict quality control in independent laboratories in Europe, China and Russia. LED lamps cost 400–2000 rubles and can be purchased at the Gauss brand store and other retail outlets.
• "Optogan" . The Optogan group of companies is one of the few in the world and the only one in Russia that has technologies and a full cycle of production of LEDs and LED equipment. In Russian retail chains, Optogan LED lamps for household lighting presented since 2011. The model range is constantly updated. The average cost of an Optogan lamp is 500–700 rubles.
• A.S.D. . Today the company sells over 1,000,000 LED lamps per month. The quality of the products has been awarded at international exhibitions, and prices start from 100 rubles. You can purchase LED lamps from this company in online stores, supermarkets, construction markets, and lighting stores.

China

First of all, it should be noted that the practice of purchasing nameless LED lamps in Chinese online stores is currently not justified. Previously, the mass consumer did exactly this, and if a cheap lamp failed, he simply bought a new one. Now this is unprofitable, and no one is responsible for the quality of such lamps. For example, LEDs of 0.15 W and 0.09 W can be produced in the same housings as those of 0.5 W, placed in the lamp in the same quantity, only the lamp will produce, for example, 400 lm instead of 1700 lm. However, in Russia you can buy certified products from well-known Chinese brands, the quality of which is beyond doubt.

• Camelion . High quality lamps, lighting equipment, power supplies and flashlights, produced for over twenty years. The company's Russian-language website presents full information about products, including certificates of conformity. The warranty on LED lamps is 3 years from the date of purchase, resource 30,000–40,000 hours. You can purchase them in large Russian retail chains, online stores and specialized lighting stores. Cost 100–450 rubles.
• Selecta . The assortment includes light sources, lamps and accessories for them. The products are widely represented in online lighting stores. For the home, we can recommend ultra-thin recessed LED lamps at a price of about 700 rubles, as well as various ceiling LED lamps costing 1200–1300 rubles.
• Estares . Trademark of the famous Chinese company MaySun. You can purchase LED lamps, LED controllable ASTRELLA lamps, interior and functional lamps for home, office and retail space in stores selling lighting equipment and LED products. Lamps can be purchased for 200–500 rubles, recessed thin LED lamps cost 1200–2500 rubles.

Russia-China

Russian-Chinese products are distinguished by a combination of innovative technologies with reliability and ease of use.

• Ecola . LED lamps GX53 produced by Ecola are energy-saving, flat, used for stretch and suspended ceilings in offices and at home. They cost 150–500 rubles and can be purchased both on the company’s website and at multi-brand online and offline retail outlets.
• Newera . The company's brand is SVeto-Led, under which LED lamps have been produced at Chinese production facilities for 9 years. You can buy them through the SVeto-Led website at a price of 170–500 rubles.

When choosing LED lamps, it is useful to read customer reviews and expert reviews. The most correct reviews are those compiled after several months of operation, as well as data from independent tests. The more reputable the manufacturer of LED lamps, the fewer discrepancies there will be between the declared and actual characteristics.

Despite the fact that the first emission of light from a solid-state LED was obtained at the beginning of the twentieth century, it took applied physics more than 80 years to create a light emitting diode (LED) operating in a spectrum suitable for the human eye, and at the same time not with cosmic value. Japanese scientists who were able to make LEDs cheap and paved the way for their widespread use in everyday life were awarded the Nobel Prize in 2014.

As consumers, we can use the advances of physics in our lives by organizing the lighting in our home or apartment with the greatest possible variability, minimal harm to the environment and with financial benefit for ourselves. Let's look at what factors need to be taken into account when choosing a modern LED lamp for your home.

When choosing a lamp for the home, we, first of all, out of habit, focus on its power. Traditionally, this indicator was measured in watts consumed. And it was clear to everyone that there is a 100-watt light bulb for a large room, and there is a 60-watt light bulb, say, for a toilet. But this story has sunk into the past along with Ilyich with the usual filament. In modern times, everything has changed.

Now, in times of energy-efficient technologies, it is incorrect to talk about the brightness of a lamp based on the power of its energy consumption. Mainly because light bulbs manufactured according to different energy saving technologies, with the same light power have different energy consumption. For example, a 30-watt lighting power corresponds to an 80-watt fluorescent and 200-watt incandescent lamp. This leads to unnecessary confusion.

It would be more correct to talk about more universal parameter, characterizing the lighting power of the llama – luminous flux brightness, which is measured in units called lumens.

The luminous flux brightness parameter is not tied to watts; it only tells us about the brightness of a particular lamp so that we can compare it with the brightness of another, made in the same or different energy-saving technology.

Before choosing the power of LED lamps, you need to remember that LED technology is constantly improving and becoming more energy efficient. Therefore, when buying a lamp, you need to carefully look at the packaging and pay attention to the luminous flux numbers in lumens. In order to orientate ourselves in these figures, we present the indicators power of LED lamps in accordance with the incandescence of conventional lamps.

Emission spectrum and color temperature

Speaking about the emission spectrum, which underlies the emitted color temperature, it should be noted that in all experiments performed using conventional incandescent lamps, energy-saving and LED lamps, it was LED lamps that demonstrated the highest quality emission spectrum.

If the spectrum of incandescent lamps is orange-yellow, the spectrum mercury lamps consists of red, green and blue, then the emission spectrum of an LED lamp includes two components: blue - from the LED itself, and a smeared spectrum - from the phosphor filling the lamp. The ratio of these two components determines color temperature LED lamps.

Color temperature is the third important (after power and brightness) parameter of an LED lamp. As you probably know, this indicator is measured in degrees Calvin. Historically, early lighting technologies produced more heat than light, and emitted light in the red-yellow spectrum.

For example, a glowing ember has a color temperature of 600 K, and most of its energy goes into heat. The higher the color temperature, the less heat the source emits.

LED bulbs can reach a color temperature of 7000K and produce standard colors ranging from warm yellow to cool white. At the same time, LED lamps do not heat up, i.e. almost all of their energy goes into useful light.

Why is it so important to have a radiator for LED lamps?

The radiator, as you might guess, serves to cool the diodes. Although the LED lamp itself does not heat up if you touch the lampshade with your hand, diodes, like any semiconductors, heat up under the influence of electricity. And they really don’t like it.

Radiator for LED lamp located between the lamp itself and the base. The person using the lighting device does not see it. It is a ribbed structure made of aluminum or its alloys. The radiator has longitudinal slots, the so-called fins, which ensure free movement of air along the slots, which ensures heat dissipation.

The subtlety in choosing LED lamps with a good radiator is as follows. In some cheaper versions of these devices, the longitudinal fins on the radiator are designed so that in a vertical position they perfectly move air inside the lamp. But in a horizontal position (i.e. if the lamp is screwed into the lighting fixture in horizontal position) – some fins will create obstacles to proper convection, which will lead to disruption of heat removal.

Technically, this problem was solved by using a cross section of the ribs in the form of an arcuate profile.

In this version of the radiator, the fins are arranged with some twist, with alternating lengths - this together makes possible the turbulent movement of the air flow, which does not depend on the position of the lamp itself relative to the horizon.

It is not visually possible to choose the right radiator, provided that it is closed from the buyer’s view. Therefore, we advise buyers to be guided by cost. When thinking about which LED lamp to choose, you should remember that more expensive models are more likely to have the correct heatsink.

Types of LED lamp bases and design options

LED lamps are available in a variety of base options.

1. The most common base is the standard E27 incandescent lamp base. LED lamps with a luminous flux power of more than 1200 lm are available only with E27 base.
2. Base E14(Mignon type) is also widely used in lighting fixtures.
3. Base GU10 with a 2-pin connector and a rotating mount with a socket are used in ceiling lamps such as reflective LED lamps.
4. Base GU5/3 with a 2-pin connector is also common in ceiling luminaires of reflector types of lamps.
5. Base G13 with 2-pin connector for ceiling lamps.

There are other types of bases that are less common, both according to the supply of manufacturers and the demand of buyers.

Numerous manufacturers of LED lamps offer various options. This:

• standard round shape,
• candle shaped lamps,
• in the shape of a candle in the wind,
• accent or spot lighting lamps.

Innovative in its design and technological implementation was the appearance of LED lamps with the ability to change colors, including red, yellow, green and blue. A lamp that changes colors is a unique find for people who love variety in the interior.

Service life, cost and manufacturers

A few years ago, the lifespan of LED bulbs was 10 years. Today famous European manufacturers They claim long service life for their lamps - up to 15, 20 and even 25 years.

Before purchasing energy-saving lighting devices, you should decide which company to choose an LED lamp.

The market for this type of product is represented by numerous manufacturers. Branded companies offer products at a higher price. This is not a tribute to fashion and not just a payment for the brand. It is these well-known manufacturers that have in their assortment not only high-quality products, but also the latest developments in this dynamically developing industry. Here it is worth mentioning:

• longer service life of such lamps,
• environmental friendliness of manufacturing materials,
• the presence of unique functions, such as the already mentioned lamp with the ability to change colors.

Among the well-known electronics manufacturers are the following companies:

• Dutch Philips,
• American General Electric,
• German Osram,
• Japanese Supra,
• German BLV.

The cost of lamps from these manufacturers will be higher than average: starting from 300 rubles. and can easily overcome the 1000 rubles mark.

There are Russian manufacturers of LED lamps on the market. Here you can name the companies Gauss, Kreonix, Start, Optogan. The price for domestic models ranges from 200 rubles. up to 1000 rubles.

In addition, the LED products market is widely represented by manufacturers offering budget lamp options starting from 130 rubles.

Final verdict on energy-saving LED lamps: how to choose

The fundamental difference with LED technology is that light is emitted by a diode as a result of the movement of electrons through a semiconductor. Therefore, their service life is very long. They emit almost no heat and do not contain harmful substances.

The color range of LED lamps is almost limitless and depends on the material of the LED and the principle of its operation.

When choosing a lamp that will illuminate your home for the next 20 years, you need to be guided by the following rules:

1. Compare the luminous flux parameter of the lamp with its color temperature to obtain better quality light, the color you need.
2. The most popular are lamps with a light power of 700-1500 lm, which approximately corresponds to an incandescent lamp of 60-100 W.
3. Know that the color temperature of the sun on a bright day is 6500 K. If you don't need brightness sunny day in the room, buy a lamp with a lower color temperature.
4. Buy LED lamps from well-known companies: do not be afraid to overpay, you will receive a high-quality safe lamp that will serve you for decades.

Video with recommendations for choosing LED lamps according to their characteristics

A well-chosen lighting design can change for the better not only the interior, but also your mood, giving you a feeling of comfort and inner warmth. For ideal lighting, both the design of the luminaires and the correct use light sources. To figure out how to choose LED lamps for your home, you need to familiarize yourself with the parameters that distinguish them from other analogues.

Many consumers, before buying LED lamps for their home, ask themselves: what are the fundamental differences between different types of lamps and what are the advantages of LED light sources? In this regard, the main technical properties of LED lamps should be noted:

• low power consumption;
• long functional life;
• absence of a “strobe effect” - LED lamps form a uniform glow that does not tire the eyes;

• high luminous efficiency;
• the ability to glow in all shades of the rainbow spectrum;
• safety of use - the lamps are environmentally friendly, do not emit harmful substances or radiation, hardly heat up and are fireproof;
• ability to operate during voltage surges - if the network voltage decreases, the lamps will operate with lower brightness;
• versatility - due to the presence of standard sockets in the design, LED lamps can be used in previously installed lamps;
• optimal price-quality ratio - manufacturers of LED products are constantly working to improve technical qualities, while the price of products decreases every year.

These properties generalize all LED light sources. However, there are differences between LED lamp models. This applies to the size of the case, the type of base, the power of the device and many other parameters. Having understood the main characteristics of LED products, we can conclude which LED lamps are best for the home.

LED lamps for 220V: circuits, device

The design of the LED lamp includes the following elements:

• diffuser - to increase the angle and distribute the light evenly. Typically made of translucent plastic or durable polycarbonate;
• LED system - the number used in the lamp determines its power, size and design. One lamp can use from one to several dozen diodes;
• aluminum PCB- ensures heat removal from the LEDs to the cooling radiator;
• radiator - made of several aluminum plates. Removes heat from the printed circuit board;
• capacitor - an element of the adapter that serves to eliminate the effect of voltage ripple at the output;
• - used to convert alternating current. It rectifies and stabilizes the voltage to power the diodes;
• base of the plinth - made of polymer, it protects the housing from electrical breakdown;
• brass base - ensures contact with the lamp socket.

Thus, the LED lamp is a block of diodes and a resistor power supply circuit that limits the current. The 220V LED lamp circuit represents the sequence in which the 220V mains voltage is supplied to the bridge rectifier element through the current limiting capacitor, designated C1 in the diagram, and resistor R2.

As a result, the LED system HL1 is supplied with constant power passing through resistor R4. The LEDs in the lamp begin to glow. The purpose of capacitor C2 in the circuit is to obtain a smoothed rectified voltage. Discharge of capacitor C1 when the LED light source is disconnected from the supply voltage occurs through resistor R1.

How to choose LED lamps for your home: comparative analysis of light sources

The high cost of LED light sources often causes doubts about the advisability of using LED lighting. You can figure this out by doing comparative analysis LED lamp and incandescent lamp. Correspondence tables for various lamp characteristics give an idea of ​​the return on investment of LED devices.

Types of LED lamp bases

For ease of use of LED products in a home network, devices are available with various options for standard sockets. This allows you to effortlessly replace old lamps with modern LED lighting sources. Main types of bases:

• E 14, E 27 - LED lamps with this base are quite common among consumers. The numbers indicate the diameter of the base (mm), the base itself has a screw connection system. Elongated bulbs with an E 14 base are usually used for small lamps, wall sconces and floor lamps. The price of LED lamps with E27, E 14 base depends on their power and the presence of a dimming function;
• GU 10 - the design of the rotary base is a two-pin connector with which the lamp is fixed to the socket. The connectors have thickenings at the ends, as evidenced by the “U” symbol in the designation of electrical accessories. The distance between the pins of such a clamp is 10 mm. Used in recessed ceiling lights;
• GU 5.3 - the distance between the pins in this base is 5.3 mm. Unlike the GU 10, the pins of this lamp holder do not have thickenings. The main application is for spot lighting lamps for suspended plasterboard ceilings;

• G 13 - this type of socket is used as a holder for lamps of type ST 8. The gap between the pin rods of the connector is 13 mm. LED lamps with this base are used for linear and ceiling lamps in places where it is necessary to illuminate an area of ​​significant size (supermarket halls, warehouses, etc.).

Useful advice! LED lamps with a socket with a pin connector should only be used in sockets with an appropriate pin spacing.

When choosing LED lamps by base type, you should give preference to those options that are used in lamps already installed in your home. If the floor lamp or have standard lamp sockets with a threaded system fast connection, then the lamp must be selected with an identical holder.

Indicators of the power ratio of LED lamps and incandescent lamps

Until recently, when incandescent lamps were used for lighting, its level was assessed by power consumption. And if it was necessary to illuminate a large room, for example, a living room or hall, then a 100 W incandescent lamp was required. In the case of LED light sources, this criterion is somewhat incorrect, since they have different light output. When using LED lamps, some of the power is lost at the adapter.

Thus, the power consumption value does not always indicate the corresponding brightness of the glow. When comparing the power of LED lamps and incandescent lamps, a factor of 8 is used. For example, to obtain the level of illumination that a conventional 60 W incandescent lamp provides, you will need an LED analogue with a power of at least 7.5 W, and a 200 W incandescent lamp can be replaced with an LED device 30 W.

For convenience, we provide data on the correspondence between the power of LED lamps and incandescent lamps. It should be noted that the indicators in the tables have average values, however, even with appropriate adjustments, you can see the advantages of LED light sources.

Table of the ratio of LED lamps and incandescent lamps by power:

Table of correspondence of watts of LED lamps to incandescent lamps and fluorescent devices:

Correspondence of incandescent lamps to LED lamps in terms of light output

The choice of LED products is impossible without taking into account the ratio of incandescent lamps and LED lamps in terms of luminous flux. The unit of measurement for luminous flux is lumen. Not all manufacturers indicate this characteristic on the product packaging. In view of this, many consumers are forced to navigate based on power consumption. But if this parameter is still specified, choosing a product will not be difficult.

Considering that the average luminous flux of an incandescent lamp is 15 lm/W, a 60 W lamp will have a light output of 900 lm (60 x 15). The luminous flux of the LED lamp is about 90 lm/W. Multiplying the power of the device 11 W by 90 lm/W, we get 990 lm. Therefore, to obtain identical brightness when replacing a 60 W incandescent lamp, you can use an 11 W LED lamp.

Useful advice! When organizing lighting in an apartment or house, LED lamps with a power of 6-10 W will be quite sufficient. Such devices will produce a luminous flux similar to the brightness of the glow when using 60 W incandescent lamps.

Often, the packaging of an LED lamp indicates that its brightness matches that of an incandescent lamp. You can also use a comparison of incandescent lamps, energy-saving and LED light sources in terms of luminous flux.

Correspondence table between LED lamps and incandescent lamps in terms of luminous flux:

Thus, when comparing incandescent lamps and LED lamps, you can see that the more powerful the device, the higher the luminous flux of any type of lamp. However, to obtain the required brightness, you can use an LED lamp with a much lower power, the energy consumption of which is 8 times lower than that of an incandescent lamp and 3 times lower than that of a fluorescent lamp.

Color temperature of LED lamps: choosing the optimal option

Unlike incandescent lamps, which produce a warm yellowish glow at any wattage, LED light sources can emit light of various shades. This is explained by the fact that the emission spectrum of a LED lamp has a varied color temperature of the glow, which is provided by two contained spectra: blue from the diode and spectrum from the phosphor - the substance filling the lamp. When mixed, these two components produce a white glow of different shades.

Thus, when purchasing LED lamps, you need to pay attention to the color of the device. Its value is expressed by the temperature in degrees Kelvin (K). To convert degrees Kelvin to the Celsius scale, you need to subtract the number 273 from their value, since the zero Kelvin mark corresponds to 273°C.

Like other parameters, the color of the glow is indicated by manufacturers in the technical documentation or on the packaging of the lamps. The designation includes a four-digit number and the letter “K”. A lamp that produces a warm white glow when illuminated will have the designation 2700 K, which is identical to the color of the luminous flux of an incandescent lamp. The color of the neutral (daytime) white glow is similar to the emission of a fluorescent light source and is designated 5000 K.

The main feature of LED lamps is that they can reach a glow temperature of up to 7000 K and still barely heat up. This indicates that all their energy is converted into a useful glow. The color of the emitted light can range from warm yellow to cool white.

Useful advice! When decorating the lighting of rooms where elderly people will be, preference should be given to lamps with a neutral white glow. This will help older family members to correctly perceive the colors of objects.

LED Beam Angle

Previously, when purchasing conventional lamps, the question did not arise about what the luminous angle of this light source was. The fact is that incandescent lamps emit light equally in all directions. The angle of luminous flux of LED lamps can be different. And this should be taken into account when choosing products.

If you use LED lamps with a narrow beam in a ceiling chandelier, then, depending on its design, only the place on the ceiling above it or on the floor below it will be illuminated. In this case, the main lighting will not correspond to its functions and the room will be dim.

A table will help you select lamps with the required luminous flux angle, which indicates the scattering angle of different lamp models and the designation corresponding to this value. As a rule, this parameter is also specified by the manufacturer on the device packaging.

Table showing the scattering angle of lamps of different models:

When choosing the scattering angle of LED lamps, it is necessary to take into account the purpose of the lighting for which they will be used. Lamps with narrow beam radiation are suitable for accent lighting of furniture, decor and small areas of the interior. Such devices are also recommended for use in LED table lamps for the desktop.

Functions of a radiator in the design of a LED lamp

To remove heat, the design of the LED lamp includes a radiator. This is done so that when heated strongly, the diode crystal does not lose its light output property. In addition, overheating reduces the lifespan of LEDs. The radiator itself is located inside between the base and the lamp body.

Radiators made of plastic, covered with a shiny film, are not able to fully remove heat and ensure the safety of the diode. But the radiator is not visible to the buyer purchasing the lamp. In some cases, you can use a simple technique: lightly tap the outer surface of the radiator with a small metal object and determine by the characteristic sound what it is made of.

Modern LED lamps have a heatsink made of aluminum or its alloys. The design of such radiators has a spiral arrangement of fins that have different lengths. This shape ensures good air circulation and high-quality heat dissipation. You can navigate the design of the radiator based on the cost of the product itself. The likelihood that you can buy an LED lamp at a low price with a high-quality radiator is very small.

Types of LED lamps by form and functionality

LED lamps come in a variety of shapes and sizes. All lamps with a pin connector are the same in shape. As for the threaded connector, lamps with such a base can have many designs:

• The pear shape is the standard lamp shape and occupies the first position in the ranking of LED lamps for the home. Used in dimensional lampshades. Has a height of 106 to 126 mm and a width of 60 mm;
• spherical shape - such models are mainly used in small round lampshades;
• candle shape - usually has a “minion” type base and is used for narrow and flat lamps;
• the shape of a candle in the wind - a creatively shaped lamp, usually with a dimming function, which provides an incredibly beautiful play of crystals;
• reflector lamp - used to create directional lighting in spotlights;
• corn - the bulb of such a lamp is similar to an ear of corn.

Useful advice! In corn lamps, the outer contacts of the diodes are energized. In view of this, they should be installed in a protective shade.

LED lamps can differ not only in shape and size, but also in internal content. Depending on functionality, lamps may have:

• pulse drivers on microcircuits;
• RGB LEDs - these bulbs can emit all the colors of the rainbow;
• remote control - brightness changes are carried out via radio from the remote control;
• built-in power supply battery - offline operation;
• control system via Wi-Fi.

There are special models of lamps that are not intended for use on a home network. These include 12 volt E27 LED lamps. The main application of these light sources is emergency lighting, lighting of industrial workplaces, building envelopes, etc. The low supply voltage ensures safety for people in the workplace.

The use of LED lamps 12 volt E27 base is also suitable for energy-independent systems of private cottages, yachts, and boats. Such lamps provide stable brightness of a neutral white shade. Devices are connected to a 220 V network through a transformer for 12 volt LED lamps.

Standards for illumination of a schoolchild's desk

Due to the fact that a child’s vision at school age is in the process of formation and improvement, it is especially important to choose the right lighting for the desktop at which he will study. To do this, it is necessary to take into account not only the location of the table and lamp, but also choose the right lamp model.

Illumination standards

There are lighting standards for both different rooms and their individual zones. It goes without saying that the most favorable for the human eye (including the child’s eye) is daylight. However, given that the child is in class, homework often has to be done at a time when there is no longer enough natural light.

Desktop lighting standards require light output to be smooth, soft, flicker-free, shadow-free, and within 300 lux. Lux is a unit of illumination created by a light flux of 1 lm distributed over a surface of 1 m². To measure the level of illumination, a special device is used - a lux meter.

If the child has a separate room, care must be taken to ensure that the curtains in the room let in as much light as possible and that the window is not cluttered with foreign objects. In addition to local lighting of the desk, the room where the student studies requires the use of main light. This will avoid eye strain and fatigue.

Selecting a table lamp model

When choosing a model table lamp It is necessary to be guided by the maximum comfort of the device and its safety. The line of this product includes dozens of models. For convenience, table lamps have a flexible holder, which allows them to be quite mobile within the table. As an option, you can use a lamp with a clothespin mount, which rigidly fixes the lamp to the surface. The use of such models eliminates the risk of accidental falls.

Useful advice! The shade of an LED table lamp for a schoolchild should completely cover the light source so that the direct light flux does not hurt the eyes.

Which is better: LED or energy saving lamp? Regarding the light sources used in table lamps, experts recommend the use of LED lamps. They emit a pleasant, uniform light without pulsating, do not burst, do not emit harmful substances and have a minimum heating temperature. The lamp power should be selected so that the light is not too saturated and not too dim.

Today, models of table LED lamps with a brightness control have appeared on sale. Such devices have several levels of illumination and touch control of the glow. Using a dimmer, you can adjust the brightness to the desired comfortable level. Dimmable lamps are the latest development in the field of lighting technology.

Why LED lamps blink: causes and solutions

Some consumers, having installed LED lamps in their home, notice that their operation is accompanied by flickering. Such lighting tires the eyes and harms vision in general. Having understood the reasons for this negative effect, you can find ways to eliminate it.

Why do LED lights blink when turned on?

There are several known reasons why LED lamps blink when turned on. Why does this happen:

• incorrect installation - it is necessary to check all the contacts of the circuit, they must be strong;
• the power of the adapter does not match the lamp used - you can replace the power supply with a new one that matches the power;
• significant voltage surges - the driver may not be able to cope with surges, the level of which goes beyond the permissible limits;

• defective product during production - it is necessary to replace the light bulb, since this product is accompanied by a warranty;
• backlit switch - it is not recommended to use such switches in conjunction with an LED light source, since when such a device is turned off, the circuit is in a closed state and contributes to the glare of the lamp;
• mismatch of wire connection - the “zero” phase should be output to the lighting device, and the wire with the phase should be output to the switch;
• the presence of household electrical appliances that create high-frequency interference;
• The LED lamp has expired.

But many people also encounter another problem when LED lamps glow after being turned off. You can find out why this happens by familiarizing yourself with the functional features of LED lamps.

Why do LED bulbs flicker or glow when the lights are off?

The reason why the LED lamp lights up when the switch is off or flickers periodically may be a switch with LED backlight. If you replace the backlit device with a regular switch, the lamp should stop flashing.

The fact is that when the electrical installation device is turned off, it does not completely open the circuit: the main supply of electricity stops, and the backlight LED closes the circuit to itself. The current passing through the diode charges the capacitor of the LED lamp driver, causing it to either blink or produce a dim light.

Another reason why an LED lamp burns when the light is off is a low-quality product. If you purchased an LED lamp at a low price and its manufacturer is unknown, the device probably contains low-power components. Light sources offered by leading manufacturing companies usually use capacitive capacitors. Of course, their cost is high, but they do not blink even when paired with an LED backlit switch.

Why do LED lamps burn out?

The main reasons for the failure of LED light sources are poor quality products or external influences. The latter include:

• a significant excess of the supply voltage - if there are voltage surges in the electrical network, preference should be given to models designed for 240V or more. You can also resort to the use of protective blocks and rectifiers;

• low-quality lamp sockets - low-quality material of the sockets tends to collapse when overheated, the contacts oxidize, thereby creating even greater heating of the LED lamp base;
• the use of powerful lamps in closed-type lampshades not intended for the use of powerful light sources;
• using the mode of frequently turning on and off LED lamps - the working life of the lamps is noticeably reduced;
• incorrect connection diagram - if one lamp fails, the fault is transmitted to other light sources in the common circuit;
• poor-quality connection of wires at nodal points of the electrical network - when connecting, it is recommended to use terminals, soldering or other modern connection options.

Useful advice! For LED lighting, use lamp models with remote power supplies. In the event of a malfunction, they can be accessed for repair or maintenance.

LED lamps for the home: product prices

After familiarizing yourself with the main characteristics of LED light sources, it becomes clear which lamps are better. LED products, although they have a high price, are indisputable technical advantages distinguishes it favorably from other devices.

You can purchase lamps by ordering products in online stores, on the websites of manufacturing companies, as well as in lighting equipment stores. The cost of an LED lamp for a home with an E 27 base similar to a 100 W incandescent lamp is from 225 rubles. and higher. The price of an LED lamp with an E14 base (minion type) varies from 96 rubles. up to 750 rub. per piece depending on the power of the device.

Almost all products purchased from official representatives are covered by a manufacturer's warranty. Warranty period can range from 2 to 5 years. In addition, any of the purchased LED lamps can be exchanged for a more suitable model or a refund can be issued within a period not exceeding 14 days from the date of purchase.

Useful advice! To ensure that there are no questions when returning LED products, it is recommended to save the product packaging.

Products from well-known and trusted manufacturers will differ significantly in price from LED products from dubious companies, which will last a few months at most. And the quality of the LEDs used in such lamps leaves much to be desired: the actual light output of such sources is much worse than the declared parameters.

Mass production of LED products is growing every year. In this regard, a cost reduction of approximately 25-30% is predicted. Nevertheless, the payback of LED lamps is possible even if they are purchased at current prices.
