For more than a century people have used incandescent lamps to illuminate streets, houses, and industrial premises. But only in recent years they began to look for alternative versions of lighting equipment. First, a fluorescent lamp became popular, and now more often both in apartments and on the street, in public places one can find a diode lamp.

Main characteristics

To properly make a choice, you need to understand the characteristics of the fixtures. Of course, you can get all the parameters from a consultant in the store, but to be 100% sure, it's better to read about the main technical parameters in advance.

Diode lamp: types and descriptionThe diode lamp has the following characteristics:

  • base and type of housing;
  • power that is consumed;
  • supply voltage;
  • power and efficiency of radiation;
  • a shade that emits light;
  • possibility of brightness adjustment;
  • temperature range;
  • constructive execution.

The most popular type of socle is E27 - the same as most incandescent lamps, which are often used in everyday life. Another common type of socle for household purposes is E14.

And for such purposes as street lighting or large production halls, the E40 type is used, which is the largest.

The power consumption of the luminaire can vary from 3 to 20 watts.

Voltage as one of the main characteristics of a luminaire selection

The supply voltage must be known in order to choose the correct model of the luminaire. Otherwise, if the voltage is too high, the lamp may just burn out or not work at all. The diode lamp has one undeniable plus in front of the incandescent lamp: the brightness of its illumination is not affected by jumps in voltage. Those. if a normal lamp dims and dims less brightly when the voltage decreases, and if it increases it can shine brighter or even burn out, then the LED lamp has a wide range of voltages at which they shine equally well.

The LED operates from a direct current with a voltage of 12V. In order for such lamps to work effectively, use special devices - drivers, circuits. They are able to drive the voltage of the external power supply to that which is more suitable for the LED.

Types of fixtures

The diode lamp is a new stage in the development of lighting devices. If a couple of years ago, such a lamp was hard to find, but now it can be purchased in almost any lighting store.

Depending on their purpose, the following types of LED lighting devices are distinguished:

  • thin LED panels that are designed to illuminate public centers and facilities (for example, offices, hospitals, schools, etc.);
  • ceiling light fixtures;
  • spotlights;
  • special lamps for plants;
  • cardan luminaires, which are used for lighting offices, hotels, salons, trading platforms;
  • furniture fixtures;
  • built-in and pendant lamps.

The most popular are ceiling, spot and wall lamps.

Diode spotlights are one of the most popular in this category. And this is not surprising, because they are the best replacement for a conventional point light and have a number of advantages.

First of all, it should be noted that this type of diode lamps has a high level of fire safety. They can be installed where there is poor ventilation, as well as in plastic and wooden niches without fear for the risk of fire. This is especially true if you are going to install a diode recessed fixture.

If you pay attention to the design of such lamps, then there will be satisfied even the most picky consumer. Today, you can choose colour from a wide selection of shapes and colors. You can also choose glow – warm, cool or neutral.

Diode lamps are ceiling. A photo

Lamps for ceilings differ not only in shape and size. They have many characteristics that depend on the purpose and location of the installation.

In shape, such devices can be round, square and rectangular. Usually round have the smallest area in comparison with the others. They can also be swivel, rotary-exit and non-rotating. Depending on the installation method, there may be diode lamps ceiling recessed and overhead.

Small round or square built-in rotary and non-rotating lamps often have a small power and are suitable for lighting small rooms and rooms. Overhead lamps of various shapes usually have large dimensions, as well as high power. They are used to illuminate large rooms.

Diode lamps for wall

Wall lamps are mainly designed for interior lighting of corridors, rooms. And since the main function of lighting is ceiling lamps, the wall perform the function of auxiliary lighting, and sometimes act as a decorative element or a night light. In connection with this, the power of such luminaires is rather small: it starts from 1 W, and the shade is usually taken not bright.

They, like ceiling, can be of different shapes and sizes. Today, manufacturers offer a variety of options for a variety of design solutions, colors and power of such devices.

Benefits

LED lamps, whether they are LED ceiling lamps, recessed or wall-mounted, for domestic purposes or for industrial buildings, have a number of undeniable advantages over conventional lamps. First of all, it is necessary to note the economy of these lamps. They consume not in one or two, but in 5-6 times less electricity than conventional incandescent lamps. If you replace all conventional lamps with LEDs in an apartment, the electricity bill for the next month will come down significantly less.

The service life of such lamps is very large. On average, it is estimated that such a lamp with a working time of 50 thousand hours will last 12-15 years, depending on how many hours per day will burn.

An indisputable advantage is that the diode, ceiling or other types of lamps do not burn out and do not lose their brightness. In the worst case, after a very long service life, the brightness of the lighting from such a luminaire can drop by no more than 30%.

Security is above all. So believe and manufacturers of LED lamps. This kind of luminaires is safe due to very low heat dissipation. Ie you do not have to worry about the fact that in the house there will be a fire due to the large heat emission from the lamp.

Also worth noting the strength of such lighting devices. If you recall incandescent lamps, each of you will have a couple of moments in your head when he accidentally dropped and smashed the light bulbs. LED lights are not so fragile, and even if you managed to break them all the same, millions of small fragments do not threaten you.

disadvantages

At first glance, LED lamps are the best option for lighting at home, as well as streets and industrial areas. But every seemingly ideal thing has its drawbacks.

Led bulbs last a long time and consume little power, but the price tag on this lamp is significantly different from the rates of conventional bulbs. The difference of led lamps and incandescent lamps is not measured in percent but in times. Although, in fairness, it should be said that this difference is more than compensated by saving of electricity. But in order for these savings to, you need to invest a round sum to replace all the lamps in the house.

Also, in order for the lamp to last a long time, you should carefully select the lamp power. For example, if your luminaire has a limitation of up to 40 W, you should not install a 6 W LED lamp, which is analogous to a 60 W incandescent lamp.

With the development of modern lighting technologies, LED lamps confidently occupy more and more space on shelves and in homes. Despite the presence of shortcomings, the advantages will more than cover the high cost of such luminaires.
