LED table lamps

One of the most popular types of modern lighting fixtures are LED table lamps of directional light, due to their aesthetic appearance, low power consumption and durability. LED lamps have good light and color rendering, which is important when illuminating work surfaces and can work in the mode of a night light and a table lamp.

Consider the main types of LED lamps, their differences and the key points of choosing lighting solutions with LEDs.

The interest in LED lighting is associated with its unique features that allow you to save energy, which has become especially important in the context of a gradual rise in energy prices. If we compare the efficiency and service life of traditional incandescent lamps (LN), economical fluorescent devices and LEDs, the latter demonstrate results that are many times higher than the capabilities of their analogues.

The attractive consumer properties of LED lighting include:

• Low power consumption rates. The efficiency of LEDs is 10 times higher than that of conventional LEDs.
• Formation of a uniform glow no stroboscopic effect, irritating to the eyes and no UV radiation harmful to peripheral vision. In this regard, LEDs are absolutely safe.
• Highest possible luminous efficiency - devices with LEDs are leading in terms of luminous efficiency among existing light sources.
• Fire safety, since they exclude strong heating, which often leads to damage to cartridges and contacts. Even with prolonged use, the lamp remains barely warm.
• Continuity of work in conditions of mains voltage drops, which is reflected only in the intensity of the luminous flux.
• The duration of the functional resource. According to manufacturers' estimates, the average lifespan of LED lamps is 45,000 hours.

The disadvantages include:

• High cost. Buying a high-quality LED lamp will cost 350-400 rubles.
• The need to use a special device to adjust the brightness of the lamp, since a conventional dimmer is not suitable.
• A significant percentage of defects in the LED market. Therefore, the declared lamp life and the actual resource may not coincide.

LED lighting is an effective way to save the family budget on electricity costs. Whether to use it is up to you. Our task is to help you navigate when choosing lighting devices of this type, considering their main characteristics and differences.

The range of LED lamps is distinguished by a variety of designs, colors and designs, allowing you to choose both the simplest model of a lamp for a nursery and an exclusive option for a living room or bedroom.

Classification of LED desktop devices:

• Interior models for decorating rooms in various modern styles - hi-tech, fusion, loft, minimalism.
• Products with extended functionality, designed for full illumination of work surfaces.
• Appliances with night light function for children. They are made using environmentally friendly plastic and are made in the form of animals, plants, fairy-tale characters and toys.

Table lamps differ in their constructive solution, and therefore there are several types of lamps.

Such products are fixed to the working surface from the side, leaving the tabletop free. They are securely attached to any horizontal surface by means of a clamp. The flexible design of the lamp column allows the position of the fixture to be adjusted. This category of products includes models with a clothespin - mini-lamps with a holder, equipped with a compact diffuser, their design no longer provides for a multi-stage elbow.

Sensory models turn on, reacting to touching a certain area of ​​the body. In devices with a dimmer, a special dimmer is provided to adjust the intensity of the luminous flux. Touch-sensitive table lighting has an extremely simple operating principle. The luminaire body is equipped with a sensor, which has a specially designed circuit that reacts to touch.

The work of the sensor is carried out as a two-terminal (capacitor), the role of which is played by the body of the lamp. A person's touch provokes an increase in the capacitance of the capacitor, which is fixed by a built-in sensor, which signals the adjustment mechanism responsible for turning on / off the lighting. In models with a dimmer, a motion sensor can be integrated, which makes it possible to turn on the device when the user approaches the work surface. Interesting models with a clock and a thermometer, which are equally suitable for schoolchildren and office workers.

These products are characterized by maximum functionality and convenience, due to being equipped with a flexible tripod, which provides the ability to move away, bring the lamp closer, and change the direction of the luminous flux. Models with adjustable height are indispensable for work that requires the utmost concentration of attention and accuracy, which increases the strain on vision.

Such lamps have a long stem, equipped with several swivel joints and a weighted base for greater stability of the device. There are models of transformers with attachment to the table, where the base is equipped with a clamp.

Particularly noteworthy are the backlit LED magnifying lamps. The scope of application of lamps with a lens is diverse - cosmetology (manicure, pedicure, tattooing, eyelash extension), medicine, jewelry, embroidery and handicraft, that is, those areas where work is associated with the elaboration of small details. A magnifying glass is installed in the lamp frame, which provides a greater view with a uniform multiple magnification of objects without distorting them.

LED magnifier lamps differ in lens magnification parameters from 3 to 12 diopters and the number of LEDs - 42-108 pieces, which affects the luminous flux power. The distribution of a large number of local light sources over the entire area of ​​the lamp contributes to the creation of a "shadowless" effect, the essence of which boils down to the formation of a general luminous flux from a multitude of local ones, which removes the shadow cast by the object.on which the lighting fixture stands.

Along with conventional lamps powered by a 220-230 V socket, folding battery models are also available. The advantage of battery-powered LED devices is their compactness and the ability to use on trips. The price of road lighting options will be higher, but their practicality and convenience are worth it.

The choice in favor of LED table lamps is most often made due to their functionality. Therefore, it is important to make sure that the model you like has the necessary characteristics in order to effectively perform the main task, taking into account the specific operating conditions.

Optimum power ratings for desktop light sources range from 60 watts to 100 watts. If you plan to illuminate a large work surface, then it is better to choose a 100-watt lamp. The power recommended by ophthalmologists is limited to 75 W, taking into account the ability of white paper to reflect light, increasing the luminous flux.

When the rooms were illuminated only by incandescent lamps (LN), the luminescence brightness was assessed based on the power consumption of electricity. Therefore, to illuminate large rooms - living rooms, halls or dining rooms, 100 Watt LN was used. With the advent of LED devices that differ in light output, it became not entirely correct to be guided by this criterion.

Lamps with LEDs partially lose power due to the adapter, therefore there may be discrepancies between the power consumption and the brightness of the glow. The power of LED devices and LN are compared using a factor of 8. Suppose, in order to obtain the illumination of a room, which is provided by a standard 60 Watt LN, you need to use an LED analogue of at least 7.5 Watt. An alternative to 200 Watt LN is a 30 W LED source.

The operating temperature range for LED devices may vary. Sources with a warm white light of a slightly yellowish tint are ideal for apartments. Such lighting promotes relaxation, making your stay as comfortable as possible. Neutral white lamps are best used to illuminate work surfaces.

Due to its characteristics, the neutral color ensures clear visibility of all details, eliminating heavy eye strain. Luminaires with a cold white color of a bluish tint, similar to daylight, are suitable for offices, public institutions.

When choosing LED products, it is important to take into account the ratio of the parameters of the luminous flux of devices with LEDs and LN. Luminous flux is measured in lumens. Not every manufacturer bothers to indicate this characteristic on the packaging of the luminaire.

In such cases, the only guideline for the consumer is the power consumption. The presence of this parameter simplifies the selection of products. For apartments, the power of LED devices up to 10 watts is enough. The luminous flux indicator of such LED lighting is similar to the power of 60 Watt LN.

All types of plinths are installed in modern LED lighting sources. The most common types of screw base are E-14 / E-27. The GU-10 swivel bases have two-pin connectors, therefore they are suitable for cartridges where the corresponding pin spacing is provided.

Ask the store which base the lamp has in the selected product. It is recommended to choose LED lamps with the same base as the rest of the lamps in the apartment. For example, when a standard lamp holder with a threaded connection is provided in a floor lamp and a chandelier, a lamp with an identical holder is selected.

If conventional LNs shine equally in all directions, then LED sources can spread the glow at different angles of 15-180 °. The newest glass-backed models are characterized by a 360 ° angle of illumination. Choosing a desktop LED-device according to the scattering angle, proceed from its purpose. With narrow beam luminaires, they create accent illumination of furnishings, accessories, and small functional areas. Such lamps are suitable for illuminating work surfaces.

It is worth knowing that high-quality power supplies are quite large. Some manufacturers tend to install small, low-power power supplies in lamps: such savings are reflected in the quality and durability of LED products.

When choosing the color of the LED lamp for work, you should avoid flashy colors, preferring calm shades of a neutral palette - white, black, gray, brown. These colors do not interfere with concentration and have a positive effect on vision. By a similar principle, a lamp is selected for a schoolchild; it is better to refuse from overly colorful design, unusual prints and acid colors in favor of monochromatic shades of psychologically comfortable shades of green, blue, muted orange.

As for the coloristic solution of decorative lamps, in this matter they start from the general color palette of the interior and from what role the lamps play in it. There are many options. They can act as accents, diluting monochrome furnishings, supporting multicolored designs, and raising the color temperature in “cool” monochromatic interiors.

In addition to the listed technical characteristics, when choosing an LED device, you need to take into account a few more points:

The plafond can be matte, dark, transparent, colored, creating a soft, soothing light, or, conversely, bright, focused. The use of colored translucent shades allows you to create lighting of a certain shade. Shades, where the top is open, help to visually increase the space, "lifting" low ceilings. Writing work is comfortable when the lamp has a shade with an open bottom.

The material from which the shade is made is also important. Lamps with a shade made of high-quality plastic are the best option for a nursery. The downside of metal shades is strong heating. When choosing an LED device for your personal account, it is best to give preference to products made of brass, glass, wood, porcelain, crystal or shades made of high-quality textiles.

The main criteria for choosing a table lamp for work are safety and maximum convenience. The presence of a movable stand provides the ability to change the height of the lamp and the direction of the light flux. Due to the flexible holder, the product gains greater mobility within the working surface. Alternatively, you can consider a model with a clothespin for rigid fixation of the device to the table, which serves as insurance against accidental falls.

When choosing the power, the purpose of the lamp is taken into account. Moderately saturated, dim lighting is optimal for an apartment. An excellent solution is dimmable LED lamps, which allow you to change the illumination, setting a comfortable light level for work or play. Sensory models with a dimmer of the same are suitable for the bedroom, living room and study.

Ideally, the color temperature of the table lamp should be that of natural daylight, which has a beneficial effect on our well-being.

A competent choice of the shape, design, color and power of an LED table lamp is half the battle, it is equally important to place it correctly. Remember that only under the condition of high-quality, well-thought-out lighting, work will be productive and vision healthy.

So what you need to know:

• Comfortable light on the work surface should be: soft - once and exclude contrasting boundaries - two.
• It is important that the glow spreads evenly over the entire working surface, which can be achieved with the correct geometry of the shade, which scatters light over the largest possible area without harm to the eyes.
• The optimal location of the luminaire is on the left side of the user. Allowed when the lamp is in front of a seated person. In both cases, the shadow will not interfere with the writing.

• When placed on the working surface of the monitor, the light source is positioned in such a way as to exclude the direction of the luminous flux to the screen.
• It is better to cover a tabletop with a reflective surface so that glare does not distract from work and does not irritate the eyes.
• When choosing a table lamp for a student, give preference to shades that cover the entire lighting element: this way you can avoid the "cutting" light effect harmful to the eyes due to the direct light flux.
