LED table lamp: an economical and modern way to organize lighting

LED lamps have recently appeared in retail outlets and have begun to replace conventional incandescent lamps and even fluorescent lamps, which also belong to the category of energy-saving lamps. The LED table lamp gained its popularity due to its compact appearance, economical power consumption, and most importantly - a significant service life. Adjustable lighting makes the luminaire multifunctional.

The LED lamp is currently the most energy saving

What are LED table lamps?

An LED lamp consists of the following main elements:

• plastic or glass case;
• base;
• drivers;
• LEDs.

Modern LED table lamps are a cost-effective alternative to outdated fluorescent

The main light source is a diode, the so-called LED, which means "light emitting diode" in Russian. The basis of such lamps is a semiconductor, which, under the influence of electricity, transmits electromagnetic radiation in the light range. To minimize power losses during conversion, a sapphire substrate is placed in the lamp. It is this combination of elements that allows a table lamp with an LED lamp to create a bright and powerful luminous flux. Radiation diverges from the light source at an angle of 5 to 160 degrees. There are the following types of LED bulbs:

1. Indicator. They are considered an outdated option, in which conductors quickly fail.
2. SMD diodes. Small-sized elements that do not heat up during operation, which significantly expands the scope of their use.
3. COB diodes. Modern technology that allows you to get a uniform luminous flux.

Interesting information! Filament semiconductors have the highest performance, emitting about 1.5 watts of light energy, which spreads over 360 °. The production of such elements is constantly evolving.

The main advantages and disadvantages of using LED table lamps

Unlike incandescent bulbs, LED luminaires have a higher light output, which is expressed as a percentage of lumens per watt. The LED is superior in light quality to energy-saving fluorescent lamps. The main reason LED lamps are so widespread is the significant energy savings, especially now that utilities continue to rise in price. LED lighting has a high level of efficiency, which saves from 20 to 90% of electricity. Other advantages that LED table lamps have:

1. Fire safety. LED lamps practically do not heat up during operation, which prolongs the life of the cartridges and internal contacts. Even after being switched on for a long time, the lamp remains slightly warm.
2. Uninterrupted work. In conditions of power supply fluctuations, the lamps continue to give the brightest possible light.
3. Long term of use. As evidenced by numerous reviews, LED table lamps have an average lifespan of about 5-7 years. In general, the period of operation of the diode is designed for 50,000 operating hours, which is 17 years. However, this statement has not yet been verified.
4. Increased consumer opportunities. Lamps can easily withstand large temperature changes and vibration. By itself, a light bulb is not considered fragile and is not as easy to break as an incandescent light bulb or any other light source.
5. High quality lighting. Depending on the manufacturer and the cost of the product, LEDs are manufactured in different spectra, the color rendering index is quite high (Ra> 80), in addition, they provide colored lighting.
6. Reliable work. LED lamps are capable of operating for a long time without compromising efficiency. The presence of a dimmer allows you to adjust the level of luminous flux, which makes it possible to use a table lamp both for work and as a night light. At the same time, the lamp reaches its maximum glow in 1-2 seconds, even at low temperatures.

The advantage of LED lighting is up to 10 times less energy consumption

Despite such a number of advantages, there are some negative aspects of using LED lamps. The main disadvantage is generally considered to be the high cost of the product. So, buying a high-quality light bulb for a table lamp will cost 300-400 rubles.

In order to regulate the degree of light flux, you will need to purchase a special regulator, because often a regular dimmer may not be enough. Another significant disadvantage is considered to be a large number of defective and inappropriate products in retail outlets. It is low-quality lamps that quickly burn out, which reduces the overall rating of LED lamps.

The main types of LED table lamps with attachment to the table and other fixing method

Before deciding on the choice of mounting for an LED lamp, you need to choose a suitable installation location for it. There are the following types of LED table lamps with mounts:

• on a clamp;
• with a clothespin;
• suction cup;
• products equipped with a bracket.

LED lamps differ in the type of attachment: with installation on the table surface, on a clamp and on a clothespin

The most common and well-known installation method is to install the lamp on a stand. This option was considered the only one for a long time. In order to make the structure more stable, its lower part is made very heavy.

Useful advice! When choosing a lamp, it is recommended to pay attention to the coating of the stand and not to purchase devices with a varnished, polished or mirror coating, which will bounce off light and create glare, which negatively affects the usability.and also causes rapid eye fatigue.

The LED table lamp on a clamp is one of the modern and reliable options that allows you to mount the light source on the edge of the table from any convenient side, or to install the device directly above the workplace on a shelf. The advantages include the safety of the structure, which firmly holds the lamp. The downside is the appearance of the mount, which does not always fit into the surrounding interior, especially if it is made in a classic style. In a room with a modern design, this option will look harmonious and attractive.

The method of attaching a LED table lamp to a clothespin is also considered popular and convenient, allowing you to fix the lamp in the right place by the edge of a table or shelf. In this case, it is important to pay attention to the quality of the spring, on which the reliability of the installation depends. In cheap models, low-quality metal is used to make the spring, which leads to a rapid expansion of the element, which can cause the device to fall over time.

Tabletop LED lamps are conventional table lamps that simply sit on the table

A separate group is LED table lamps that are mounted on the wall. This method allows you to free up space on the table, as well as prevent the device from falling. In this case, it is important to choose the right installation location the first time, because it will not be so easy to transfer the device already fixed on the wall.

LED table lamp: construction types

In addition to the installation method, you should also pay attention to the lamp legs. In this case, it is necessary to select not only the material and shape, but also the type of construction, which affects the ease of use. Depending on the structural features of the LED lamp, certain options for lamps are distinguished.

On a stationary leg. The classic type of luminaire design, assuming only one fixture position. The body of such lamps can be made of metal, wood, plastic, or by combining these materials. There are also unusual types of cases made of bamboo, wire or forged metal. These luminaires are considered reliable, but they have a significant drawback - the inability to deploy the device at the required moment without rearrangement.

Flexible LED table lamps are considered more convenient, because at any time you can change the angle of incidence, height or direction of the light flux. Most often, the flexible leg is a metal corrugation that holds well in any position. Sometimes the leg consists of a flexible shaft covered with corrugated metal or plastic. This option is found in inexpensive models.

Flexible LED table lamps are the most convenient, as you can change the direction of the light flux

Telescopic folding LED table lamp consists of several autonomous movable sections made of metal tubes, by moving which, it is possible to adjust the height and location of the shade relative to the table surface. If you buy an inexpensive folding lamp, springs are used to hold the body in a certain position, but over time they stretch and lose their properties. A more durable option is an LED folding table lamp with clamping bolts that need to be tightened from time to time.

Non-standard options include a magnifying glass table lamp with LED illumination, widely used in cosmetology, architecture or medicine. This version of the luminaire becomes indispensable in service centers that deal with the repair of equipment equipped with a large number of small parts. And also the lamp is useful for those who are fond of needlework or jewelry.The design of the luminaire consists of LED bulbs mounted in a magnifying glass in a frame. There is an opportunity to purchase a table version of the lamp on a stand, clamp or with a bracket.

A diode LED table lamp-magnifier is usually equipped with a magnifying glass (the optical power of the lens is 3-12 diopters) and a large number of autonomous diodes, the number of which will affect the luminous flux power. Thanks to the large number of diodes distributed over the lamp area, it is possible to achieve a shadowless effect on the working surface.

Based on the structural features of the LED lamp, certain options for lamps are distinguished

Basic power options for LED table lamps

All table lamps, depending on the method of connecting to the network, can be divided into three large groups:

• using wires;
• wireless;
• combined.

The first option is considered a traditional volatile device, which necessarily requires access to an outlet for operation. The main advantage of LED lamps is low energy consumption, which allows you not to worry about utility bills.

An advantage is the fact that, in addition to stationary options operating from a 220 V outlet, mobile LED table lamps with a rechargeable or battery operated are also produced. You need to understand that this option will cost a little more than a conventional lamp with a wire. The main disadvantage of the desktop rechargeable LED lamp is the need to recharge the power supply, and it is also worth noting its rapid wear, especially with frequent or improper charging.

USB wireless LED desk lamps are most commonly used in conjunction with a computer

The combined type is universal, allowing you to use the power supply that is available. The advantage of such devices is that if the light is suddenly turned off, you can safely continue working.

A separate group includes wireless LED USB desk lamps, which are most often used in conjunction with a computer or laptop. The small size of the light bulb is enough to illuminate the surface of a keyboard, an e-book or a spread of a regular paper book.

Key Features of LED Table Lamps

Table lamps are also classified according to the type of shutdown, in this case, a pull-cord or touch switch is distinguished. The most traditional is the push-button switch, which can be placed on the wire or on the case. In this case, the convenience of use lies precisely in the location of the button.

Useful advice! Luminaires with touch switches and dimmers are 15-25% more expensive than other models, but they will not always be convenient. Therefore, it is recommended to test the device before buying.

Lamps are distinguished by the type of switch: with a switch on a cord, touch control, with a dimmer, with a push button switch on the lamp body

A feature of sensor models is to regulate the operation of the device by touching a specific area on the body. The LED table lamp with dimmer is equipped with a special device - a dimmer that adjusts the power of the light beam. The principle of operation of the device is quite simple: a sensor with a built-in microcircuit is located on the case and reacts to touch.

Other parameters to pay attention to when choosing a luminaire

As for the question of how many watts LED lamps should emit, it is recommended to give preference to models that correspond to 60 or 100 W, the optimal power is 75 W. It is this light that ophthalmologists consider the most acceptable for vision. At the same time, doctors take into account the ability of white paper to reflect light and increase the power of the light beam.

In order to compare the power of LED and incandescent lamps, you need to use a factor of 8. Thus, to get lighting similar to 75 W, you should purchase a 9 W LED light source. An alternative to a 200 watt incandescent lamp is a 30 watt LED.

Depending on the method of using the table lamp, the operating temperature range is also selected. If you install the device on a dressing table near the bed purely for lighting, a yellowish lamp is more suitable, which is most easily perceived by the eye, relaxes and makes the rest as comfortable as possible. If the light is to be mounted on a desktop, it is best to choose a bright cool white light that best illuminates the surface. The neutral white color also ensures that the necessary details are clearly visible, while avoiding undue stress on the visual organs.

LED lamps are simple lighting fixtures, however, they have their own performance characteristics that you need to know when choosing a lamp.

When buying, you need to pay attention to the type of base, because the choice of the bulb itself depends on this criterion. The luminaires most often contain screw bases E-14 or E-27, which are considered the most common. The swivel base GU-10 features a 2-pin connector and is suitable for special cartridges.

Useful advice! It is best to choose a lamp with the same type of base that is found in most of the lamps in the apartment, so there will always be a spare light bulb available.

What does the rating of LED lamp manufacturers look like?

Today, there is a large selection of both domestic and foreign companies that offer a large selection of models of LED lamps that differ in price and characteristics.

As for Russian manufacturers, Era LED table lamps are in the first place in popularity. Among the models, you can find options with built-in light filters, motion sensors and other accessories, while the price of such lamps is lower than that of foreign manufacturers, and the choice of various designs is quite large. Another advantage of Era is the presence of its own engineering center, which is constantly developing new models of lighting fixtures.

Among Russian manufacturers, the most popular are LED table lamps "Era"

So, most of the latest models of lighting fixtures are equipped with automated controls that help adjust the color mode and lighting level. Among the shortcomings, one can single out the fact that most of the company's lamps are distinguished by rather fragile fasteners, which must be reinforced with additional parts. As an example, consider the ERA model NLED-461-7W-BG. The price of an LED table lamp is up to 1750 rubles. The model has a modern design made in high-tech style, and has the following parameters:

• power - 7 W;
• the presence of a dimmer;
• the presence of adjustment of the tilt and rotation of the plafond;
• base type - built-in LED lamp;
• voltage - 220 V.

One of the most popular foreign manufacturers is the Japanese company Supra. Particularly noteworthy is the SL-TL315 model, which is positioned as a universal option, suitable for both office and schoolchildren's desktop equipment.

The Supra LED table lamp is equipped with a touch control system and an adjustable body. The luminaire contains 30 LEDs, which are designed for 50 thousand hours of operation. Installation of the lamp on the surface of the table is carried out using a stand, where the touch panel is located, which regulates not only the level, but also the heat of the light flux. There are two versions of shades available for sale - metal and plastic. Model price - from 1800 rubles.

Supra is a popular foreign LED table lamp manufacturer

Another well-known manufacturer of lighting equipment is the Chinese company Uniel, which manufactures both budget and more expensive models. Among the popular Uniel LED table lamps, the following stand out:

1. TLD-502. Refers to the most expensive models of table lamps, equipped with a touch switch and dimmer. In the manufacture of the lamp body, metal and plastic are combined. The power of the device is 8 W, which is equivalent to 60 W of an incandescent lamp. Model price - from 4 thousand rubles.
2. TLD-556. A cheaper model of a tabletop lighting fixture with a cutting edge design. Product weight - only 300 g; the ability to easily fold and the built-in 1000 mAh battery allows you to take the device with you on trips and trips. At low power (only 3 W), the luminous flux rate is 105 lm.

LED table lamps are considered to be the modern way of organizing the workplace. In addition to the fact that the use of diodes allows you to save on electricity, the lamps themselves are distinguished by a compact and interesting design. In retail outlets, it is easy to find product options that will fit into both classic and modern interiors. The ability to adjust the intensity of the light flux makes it possible to use the lamp both as a light source and as a night light, which is especially important in a children's room. The minimum energy consumption allows you to safely leave the device turned on even for the whole day.
