LED panels (they are also LED-panels) are considered one of the practical and stylish ways to illuminate rooms of various sizes and functional purposes. These lighting devices have a huge number of advantages, which include: easy use, safety, energy efficiency, small size. In addition, they are able to produce high-quality light for a long working period. As a result, in today's market, these devices have gained well-deserved popularity.

The body of such lamps acts as a supporting element, which contains all other components. It can be made of plastic / metal, which will depend on the design features of a particular model. LEDs are mounted on the walls on the side and are located opposite each other around the entire perimeter of the case. Outside the panel there is a light-conducting lens, and on the back there is a special cover, through which the interior of the lamp is covered and due to which the internal components are protected.An internal diffuser and a reflective film are also installed inside. In addition to the described elements, a special driver can be enclosed in the case, with the help of which the device is switched on and operated when it is directly connected to the mains.
Simply put, the design of the LED panel is a kind of "sandwich" and consists of:
In terms of technical parameters, the devices in question may differ in form and purpose.

Panels can be rectangular, square, round or oval. Their size can vary, and the average thickness of popular models is 14 millimeters. It should be noted that the shape and dimensions of the product used are always dependent on the size of the room where it will be installed. Thus, the above forms have the following features:
Typically, LED panels are used for outdoor advertising or indoor space lighting. Ceiling versions are traditionally installed in interior spaces, mainly to replace classic fluorescent lamps while reducing energy costs. The thickness of the ceiling models allows them to be used even in rooms with low ceilings. It is also allowed to place them on suspended and stretch ceilings, walls. Advertising panels are always large, installed only vertically and have an increased protection class (at least 65th), because they are usually exposed to adverse weather conditions.
As a rule, the considered devices are installed in the premises of the following types:
And outdoor advertising panels have long pushed the famous neon signs out of the market.
The main technical parameters possessed by diode panels are:

LED panel devices can produce light of various shades that are suitable for lighting rooms for a particular purpose. From this it is clear that an appropriate color temperature must be selected for each room (the lower this indicator, the more yellow and warmer the outgoing light will be). This parameter is defined in Kelvin and the following rating of values can be built:
Experts recommend using warm white and warm yellow shades in the living rooms of residential buildings and apartments, bedrooms, recreation areas and restaurants - in general, wherever the atmosphere contributes to a pleasant pastime, rest and relaxation. Cool white light will improve concentration, so it is more often used in medical institutions or assembly shops in the industrial sector. However, it is rather difficult to stay in such a light for a long time. Neutral white light is best suited for office work - it does not tire a person and at the same time increases his efficiency.
Their undoubted advantages include:
However, these products also have a number of disadvantages:
For convenience, this parameter can be compared with the indicator of gasoline consumption per 100 kilometers for a car. LED panels use Lumens per Watt (lm/W), which measures how much light is generated from 1 watt of energy. For ordinary incandescent lamps, this figure is 10-20 lm / W, and for LEDs it is already 120-170 lm / W.This shows that for the same unit of energy, the LED produces almost 6 times more light at the output.
When purchasing LED panels, you should pay attention to the following points:
Separately, it is worth mentioning the price moment. Naturally, LED panels, as a modern product, have a high cost. This is especially true of well-known brands - their prices start at 2000 rubles. Accordingly, if the product costs less than 900 rubles, and the technical characteristics are declared at the upper limits, then this circumstance should make the buyer doubt the quality of such products.
The type of ceiling will determine how the panel will be installed. It is worth noting that this work will not be particularly difficult, but each option has its own specifics. As a result, the panels can be fixed in three ways:
The lighting in question can be fixed both on a concrete and on a wooden surface by means of a cable fastening. Cables allow you to adjust the height of the lamp. Fasteners of this type are sold immediately complete with some types of panels, but it is not difficult to find them separately. The complexity of this installation method lies in the difficulty of applying the correct markup. It must be carried out with maximum accuracy, given that this will have to be done while holding the canopy of the device and standing on a ladder or stepladder. After marking the points, it is necessary to make holes in them in the ceiling for placing fasteners for cable suspensions there. Fixing will be done with self-tapping screws on plastic dowels. The final suspension will not cause problems.
If the cable method cannot be implemented, then fastening can be done using ordinary metal corners. Corners will need 8 pieces - 4 for the ceiling, 4 for the panel itself. Then each of the corners on the panel and on the ceiling are fastened together with screws.
It is necessary to indicate that initially LED panels were just designed for installation on ceilings of this type. All structures have a frame made of profiles, which, upon completion of installation, will mask all wiring. The installation procedure is very simple: a certain area of \u200b\u200bsheathing in one of the places of the frame is simply removed, after which a panel is mounted in the vacant place. The main thing here is to correctly fix the panel on the same level with the rest of the ceiling material.It is necessary to make holes for the panel itself very precisely, and to adjust the height it is allowed to use homemade plastic or wood linings.
This option is probably the most difficult, because it is necessary to accept the specifics of the device of such a ceiling, as well as the material for its manufacture. The main danger is that during installation work it can easily be deformed. Further, if the incision is made incorrectly, then such an incision can no longer be sealed and cannot be corrected. Therefore, it is better to install with a cable method with the possibility of height adjustment (i.e. the cables can be tightened in the future). Another way is to install special fastening structures on the metal profile in special places. Then stretch the ceiling, and then mount the panel on pre-installed fasteners. However, this method can only be applied at the design stage.
This model is distinguished by high environmental safety, because it does not contain substances hazardous and harmful to human health and the environment that could be released during operation for a full service life. It consumes a minimum amount of electricity and can easily replace LPO 4 x 18. Scope of application: administrative and public premises, industrial and office buildings, shops and trade pavilions, lobbies, etc. The recommended cost for retail chains is 1240 rubles.

LED panels are ideal for lighting home spaces of various sizes, and they have no restrictions on ceiling heights. If an extremely expensive model is purchased, and the ceiling has critical features, then it is better to entrust the installation to a specialist. It is worth remembering that high-quality installation will affect the life of the product.
If we talk about the commercial use of LED panels, then they are perfect for supermarkets and shopping centers, industrial enterprises and production shops, as well as for use as advertising signs. Their installation is possible in almost any position, and the energy consumption for them will be much less. Considering that the average thickness of the product is 1 centimeter, the dimensions of the installation site will practically not play a role.
