Table LED lamp: lighting the way organizations

LED lamp relatively recently appeared in retail outlets and began to replace conventional incandescent and even fluorescent lights, which also belong to the category of energy-saving. Its popular desktop LED lamp received its compact appearance, economical consumption of electricity, and most importantly - a significant period of operation. Ability to adjust the lighting that makes the luminaire multifunctional.

What are the LED lamps Desktop lamps

LED lamp consists of the basic elements:

• plastic or glass housing;
• cap;
• driver;
• LEDs.

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

1. Indicator. Considered obsolete embodiment in which conductors are easily damaged.
2. SMD-LEDs. Smaller size elements that do not heat up during operation, greatly broadens the scope of their use.
3. COB diodes. Modern technology to provide a uniform light output.

Interesting information! The highest performance semiconductors differ filaments issuing about 1.5 W of light energy, which extends over 360 °. The production of such elements is constantly evolving.

The main advantages and disadvantages of using LED lamps Desktop

Unlike incandescent lamps LED lamps have a higher return light, which is expressed as a percentage of lumens per watt. LED superior in quality of light and energy-saving fluorescent lamps. The main reason that LED lamps are widely used - a significant energy savings, especially now that utilities continue to steadily rise in price. LED-lighting a high level of efficiency, in which saving of 20 to 90% energy. Other advantages that are inherent in LED bulbs for table lamps:

1. Fire safety. ICE fixtures virtually no heat during operation, which extends the life of cartridges and internal contacts. Even after a long turn on the lamp remains lukewarm.
2. Trouble-free operation. In the conditions of the mains voltage drops lamps continue to provide maximum glare.
3. Long term use. As evidenced by the numerous reviews, LED desk lamps have an average life of about 5-7 years. In general, the period of operation of the diode is designed for 50,000 hours, which is 17 years. However, this assertion check has failed.
4. Increased consumer opportunities. Lamps can safely tolerate big swings temperature, and vibration. By itself, the lamp is not considered to be fragile and break it is not as easy as the incandescent lamp, or any other light source.
5. High quality lighting. Depending on the manufacturer of the product and the cost of LEDs are produced in different spectra, they ensure the creation of a color CRI is quite high (Ra> 80), in addition, lighting.
6. Reliable operation. LED lamps can work for a long time without sacrificing efficiency. The presence of dimmer allows you to adjust the level of light flux that makes it possible to use a desk lamp for work, and as a nightlight. When this reaches a maximum emission lamp for 1-2 seconds, even at low temperature.

Despite so many advantages, we can highlight some negative aspects of the use of LED lamps. The main drawback is generally considered the high cost of the product. Thus, the purchase of high quality bulbs for table lamps will cost 300-400 rubles.

In order to regulate the degree of light stream, you need to buy a special controller, because often conventional dimmer may not be enough. Another significant drawback is considered to be a large number of defective or improper performance of products in retail outlets. It substandard bulbs burn out quickly, which reduces the overall rating of the LED lamps.

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

Before you make the right choice for mounting the LED lamp, you need to pick up for her a suitable place of installation. Allocate these types of LED desk lamps with attachment:

• to clamp;
• with a pin;
• suction cup;
• Products equipped with a bracket.

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

Useful advice!When choosing a lamp is recommended to pay attention to covering the stand and not buy devices with lacquered, polished or mirror coating that will repel the light and create a glare that adversely affects the ease of use, and also causes fatigue eye.

Table LED lamp to clamp refers to modern and reliable options that let you mount light source at the edge of the table with any suitable side or place the device directly above the workplace on shelf. Of the benefits you can highlight the safety of the construction, which firmly holds the lamp. The downside is considered the appearance of attachment, do not always fit into the surrounding interior, especially if it is made in a classic style. The room has a modern design, this option will look harmonious and attractive.

A method of mounting the LED lamp on the table clothespin also considered a popular and convenient, allowing to fix the lamp in the right place at the edge of a table or shelf. In this case, it is important to pay attention to the quality of the springs, from which depends the reliability of the installation. The cheapest models used for manufacturing low-quality metal springs, which leads to rapid stretching of the element, due to which the device may eventually fall.

In a separate group can be identified LED Table Lamp, which are mounted on the wall. This method allows you to make room on the table, as well as to prevent a fall. In this case, it is important the first time to choose the right mounting location, because the move is already attached to the wall of the device will not be easy.

Table LED lamp: types of construction

In addition to the installation method, you should pay attention to the lamp foot. In this case, you need to select not only the material and shape, but also the type of construction, which affects usability. Depending on the structural features of the LED bulbs emit certain variants of fixtures.

On the stationary leg. The classic type of luminaire design, involving only one position of the device. The housing of such tubes may be made of metal, wood, plastic, or else by a combination of these materials. Occur and unusual enclosures made of bamboo, wire or wrought iron. These lamps are considered reliable, but differ in significant drawback - the inability to expand the device in the desired time without having to move.

Flexible LED lamp board are considered more convenient, because at any moment can change the angle of incidence or the direction of the height of the luminous flux. Most often, the flexible stem is a corrugated metal, which are well retained in any position. Sometimes leg consists of a flexible rod, covered with corrugated metal or plastic. This variant occurs in inexpensive models.

Telescopic folding LED table lamp consists of several autonomous mobile sections made their metal tubes, which are moving, it is possible to adjust the height and position of the ceiling relative to the surface table. If you buy an inexpensive collapsible tube, then to keep the body in a certain position using a spring, but over time they stretch and lose their properties. More durable option is considered to be foldable LED table lamp with clamping bolts, which from time to time it is necessary to tighten.

For embodiments may include non-standard desk lamp magnifier with LED backlight, widely used in cosmetics, medicine or architecture. This option is becoming an indispensable fixture in the service centers, which deal with equipment repair, equipped with lots of fine detail. And light is useful to those who are fond of handicrafts and jewelry business. The design of the luminaire is an LED light bulb mounted in the magnifying glass in the frame. There is an opportunity to purchase a desktop version of the lamp on a stand, with a clamp or bracket.

Diode LED desk lamp magnifier is usually equipped with a magnifying glass (optical power of the lens is 3-12 diopters) and a large number of autonomous diodes the number of which will influence the power luminous flux. Due to the large number of diodes distributed on the lamp area can achieve shadowless effect on the working surface.

Main dining options LED Desk Lamp

All table lamps, depending on how you connect to the network, can be divided into three large groups:

• using wires;
• wireless;
• combined.

The first option is a traditional volatile device, which works to necessarily require access to a power outlet. The main advantage of LED lamps - low energy consumption, allowing you to not worry about utilities.

The advantage is considered to be the fact that, in addition to the fixed option, running from the outlet 220, manufactured and mobile desktop LED lamp with a battery or a battery. It should be understood that this option will cost more expensive than ordinary lamps with wire. The main disadvantage of desktop rechargeable LED lamp is the need to recharge feeding device, and it is worth noting its rapid deterioration, especially for frequent or irregular charge.

Combined type is universal, allowing to use the power that is available. The advantage of these devices is that you can safely continue to work when a sudden blackout.

In a separate group of distinguished wireless USB-LED Table Lamp, which are often used in conjunction with a computer or laptop. Small bulb size is sufficient to illuminate the surface of the keyboard, an electronic book or a reversal of the conventional paper books.

Main characteristics of LED desk lamps

Desk lamps are also categorized by the type of shutdown, in this case, the release cord or touch switch. The most traditional of these is pushbutton switch that can be placed on the wire or on the housing. In this case, the usability is precisely the location of the buttons.

Useful advice!Fixtures with touch switches and dimmers at a price 15-25% more expensive than the other models, but not always, they will be comfortable. Therefore, before purchase is recommended to test the device.

Feature touch models is to regulate the operation of the device by touching the specific site on the body. Table LED lamp with dimmer equipped with a special device - dimmer corrective power of the light beam. The principle of operation is quite simple: a sensor of the chip located on the body and responds to touch.

The touch device according to the principle of the capacitor, which performs the role luminaire. Some more expensive models are equipped with a dimmer, reacting to movement, which lets you select the unit at the approach to it. Current models are often complemented by built-in digital clock and thermometer, which is especially important for home or office use.

Other parameters that should be considered when choosing lamp

As to the question, how many watts LED lamps must emit, here it is recommended to give preference to models that fit 60 or 100 watts, optimum power is 75 watts. It is this light ophthalmologists believe the most acceptable to the eye. At the same time, doctors take into account the ability of the white paper to reflect light and enhance the power of the beam of light.

In order to compare the power LED and incandescent bulbs, use factor 8. Thus, in order to get coverage similar indicator 75 W, you must purchase an LED light source output of 9 watts. An alternative to incandescent bulbs of 200 watts is considered a 30-watt LED.

Depending on the method of use of the table lamp is selected and the operating temperature range. If you install the unit on the dresser next to the bed especially for lighting, more suitable lamp yellowish color, which is most easily perceived by the eye, relaxes and makes the rest possible comfortable. If the luminaire is installed on the desktop, it is better to choose a bright cold white light that best illuminates the surface. The neutral white color also provides clear visibility of the necessary parts and thus eliminates excessive strain on the organs of vision.

When you purchase is necessary to pay attention to the type of cap, because this criterion depends on the choice of the most light bulbs. The fixtures often present screw caps E-14 or E-27, which are considered the most prevalent. Rotary cap GU-10 connector is characterized by pin 2 and is suitable for special cartridges.

Useful advice! It is best to choose a lamp with the same type of base that is present in most of the fixtures in the apartment, so that is always available is a fallback bulbs.

What is the ranking of manufacturers of LED lamps

To date, there is a large selection of both domestic and foreign companies, which offer a great variety of models of LED lamps that differ in price and performance.

As for the Russian manufacturers, in the first place in popularity are desktop LED lamp "Era". Among the models can be found variants with integrated light filter, motion sensors and other accessories, while the price of these lamps is lower than that of foreign producers, and the choice of a variety of designs pretty big. Another advantage of the company "Era" is considered to be the presence of its own engineering center, which is constantly engaged in developing new models of lamps.

So, most of the latest models of lighting fixtures are equipped with automatic control, which helps to regulate the color mode and the illumination level. Among the shortcomings can be identified by the fact that most of the company's lighting fixtures has a rather fragile fixture you want to enhance with additional details. As an example, consider the model ERA NLED-461-7W-BG. Price LED table lamp - up to 1750 rubles. The model features a modern design, made in the style of hi-tech, and has the following parameters:

• Power - 7W;

• voltage - 220 V.

One of the most popular foreign manufacturers considered the Japanese firm Supra. Special attention should be paid Model SL-TL315, which is positioned as a versatile option that is suitable for the office, and for the working student desk equipment.

Table LED lamp Supra features a touch control system and adjustable body. The lamp is integrated 30 LEDs, which are designed for 50 thousand. hours of operation. Installation lamp on the table surface by using the stand, and where the touch panel is regulating not only the level but also the heat of the light flux. metal and plastic - For sale are two options available lampshades. Price models - from 1800 rubles.

Another well-known manufacturer of lighting equipment is considered UNIEL Chinese firm, which produces both low cost and more expensive models. Among the popular LED desk lamps Uniel are the following:

1. TLD-502. It is among the most expensive models of table lamps with touch switches and dimmer. In the manufacture of the lamp housing combined metal and plastic. Power unit - 8 W, equivalent to 60 W incandescent lamp. Price models - from 4 thousand. rub.
2. TLD-556. Cheaper model lighting desktop device, designed in a very modern design. Product weight - only 300 grams; ability to be easily folded and embedded battery capacity of 1000 mAh allows to take the device with them on trips and trip. At low power (of 3 W) the velocity of the luminous flux is 105 lumens.

LED desk lamps are considered to be a modern way of organizing the workplace. Apart from the fact that the use of diodes allows to save on electricity, the lamp itself is compact and interesting design. In shops easy to find options for products that fit both the classic and modern interior. The ability to adjust the intensity of the light flux enables the use of light and as a light source, and as a night-light, which is especially important in nursery. Minimal power consumption allows without fear leave the appliance switched on at least for the day.
