Today I would like to provide readers with the information portal itself electrician that is LED lamps, which have the principle of work and what they are better than other light sources.This topic is relevant in that it is for them the future (diodes), so now let's review the most important technical characteristics of the product!

The components of the device

device, in other words LED lamp design is represented by the following elements:

  1. plastic light diffuser;
  2. LEDs (usually not less than 5 pieces);
  3. setup fee;
  4. aluminum radiator (removes heat);
  5. driver converting the mains voltage;
  6. ventilation holes (through which the air circulation takes place, whereby the driver cooled);
  7. base (a conductor of electric current from the mains).

can see that the light bulb in a rather complex mechanism, the principle of action which is different from the alternative light sources.It is because of the driver, which is present in the circuit, the light may flicker when connected to a dimmer.In this case, it is recommended to use special dimmable LED lamps.

Feature

main technical characteristics of LED lighting lamps:

  • type cap.Maybe a screw (marked E27, E14) and pin (G19, G13, GU10 and so on).
  • power consumption - from 3 to 30 watts.
  • rated voltage of 220 V.
  • Luminous flux - 250 lm to 2500 lm (an average of 100 lm / W 1).
  • Operating temperature range from -10 to + 40 ° C.
  • Degree of protection (the IP index, is taken into account in the event that an LED lamp is installed in rooms with excessive humidity or dust. For example, when installing wiring in the garage and bath).
  • color temperature from 2700 to 6400 Kelvin.
  • service life of 30 to 50 thousand. Hours.
  • Overall dimensions (length x width x height).
  • Weight (each individual product).

Types

As such varieties of LED lamps do not exist, can not be said about halogen lamps.Usually they can be distinguished by the type of cap, operating power and color of the glow.

About pedestals we mentioned above, considering the specifications.

The main types of caps

draw your attention to the fact that to learn all kinds of caps is difficult electrician novice, the more that it is not necessary to do.If you need to buy a new LED bulb is best to take to the store and show the old seller.Regarding

operation power, the lamp can be operated on 4, 12 and 220 V. The first group used in decorative lighting facilities, the last two can be used as general lighting.

Color Glow LED lamps can be different: warm, cool, day, etc. (unlike shown in the photo below).

Scope

Scope LEDs knows no limits.They can be used wherever possible: in supermarkets, in the interior lighting, street lighting installation, for decorative lighting and furniture of different architectural objects.The most common light bulbs are used in the installation of lighting in the apartment and a private home.They worked well because of the many advantages, which we'll talk further.

Benefits

Finally, we moved on to the most interesting part of the article, in which we consider the pros and cons of LED lamps for the home.

main advantages are:

  • highest energy savings (products can save 10 times more electricity consumption than incandescent lamps);
  • highest luminous efficiency, which reaches a record 120 lm / W 1;
  • lifespan greatly exceeds 40,000 hours, which is also the highest rate;
  • wide range of products of different shape, size and color of luminescence;
  • high strength of the body;
  • does not bring harm to the environment (no inert gas inside the bulb);
  • operates at a voltage jumps;
  • number of on / off does not affect the service life;
  • heating small (up to 60 degrees Celsius), so you can not be afraid when you install the product near flammable materials.

Disadvantages The main disadvantage of LED lamp is its high cost compared to other light sources.

also minuses products include:

  • emission spectrum can adversely affect human health;
  • light is highly directional, which requires the installation of several LED lights for uniform illumination of small rooms;
  • for the efficient and continuous operation is necessary to buy expensive radiators, drivers and power supplies;
  • service life does not correspond to the actual on the package (due to the fact that over time, the crystals begin to spontaneously go out);
  • most products function poorly when connected dimmer.

Here you also got acquainted with the technical characteristics, advantages and disadvantages of LED lamps.To finally prove to you that these products are the best among its competitors, provide some comparison tables:

I would also like to note that in the world practice LEDs are lead in most countries.The only exception is Japan, which still gives preference to fluorescent lamps.Knocked out the pros and cons, we can say that today the LED lamps in almost all respects better than the other light sources.
