LED lamp overview
The device, in other words, the design of the LED lamp is represented by the following elements:
- plastic light diffuser;
- LEDs (usually at least 5 pieces);
- installation fee;
- aluminum radiator (removes heat);
- a driver that converts mains voltage;
- ventilation holes (air circulation occurs through them, as a result of which the driver cools down);
- base (is a conductor of electric current from the network).
It is seen that inside the bulb is a rather complex mechanism, the principle of which is different from alternative light sources. It is because of the driver, which is present in the circuit, that the light can flash when connected to a dimmer. In this case, it is recommended to use special dimmable led bulbs.
Characteristic
Main technical characteristics of LED lighting lamps:
- Type of cap. It can be screw (marking E27, E14) and pin (G19, G13, GU10, etc.).
- Power consumption - from 3 to 30 watts.
- Rated voltage 220 V.
- Luminous flux - from 250 Lm to 2500 Lm (average 100 Lm / 1 W).
- Operating temperature range from -10 to + 40 ° С.
- Degree of protection (IP index, taken into account if the LED lamp will be installed in rooms with excessive moisture or dust. For example, when installation of electrical wiring in the garage and bathhouse).
- Color temperature from 2700 to 6400 Kelvin.
- Service life from 30 to 50 thousand hours.
- Overall dimensions (length * width * height).
- Weight (each product is individual).
Views
As such, a variety of LED lamps does not exist, which can not be said about halogen lamps. Usually they can be distinguished by the type of cap, working food and the color of the glow.
ABOUT socles We have already said above, considering technical specifications.
We draw your attention to the fact that to learn everything types of socles It’s quite difficult for a novice electrician, especially since this is not necessary at all. If you need to buy a new LED light bulb, it is best to take the old one to the store and show it to the seller.
Concerning working power, then the lamps can work from 4, 12 and 220 V. The first group is used in decorative illumination of objects, the last two can be used as general lighting.
Color glow LED lamps can be different: warm light, cold, daylight, etc. (the difference is shown in the photo below).
Application area
The scope of LEDs knows no limits. They can be used wherever possible: in supermarkets, in interior lighting, for installation of street lighting, for decorative lighting of furniture and various architectural objects. Most often, light bulbs are used when installation of lighting in the apartment and private house. They have proven themselves because of the many advantages that we will talk about later.
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.
The main advantages are:
- highest energy savings (products can save 10 times more electricity consumed than incandescent lamps);
- highest light output, which reaches a record 120 Lm / 1 W;
- service life significantly exceeds 40,000 hours, which is also the highest rate;
- a wide range of products of various shapes, colors and dimensions;
- high durability of the case;
- does not harm the environment (does not have inert gases inside the flask);
- works with power surges;
- the number of on / off does not affect the service life;
- heating is small (up to 60 degrees Celsius), so you can not be afraid when installing the product next to flammable materials.
disadvantages
The main disadvantage of LED lamps is its high cost compared to other lighting sources.
Also, the disadvantages of the products include:
- the spectrum of the glow can negatively affect the well-being of a person;
- the light is narrowly focused, which requires the installation of several LED bulbs for uniform illumination of a small room;
- for efficient and long-term operation, it is necessary to purchase expensive radiators, drivers, and power supplies;
- the service life indicated on the package does not correspond to the real one (due to the fact that the crystals begin to fade spontaneously over time);
- most products do not function well with connecting a dimmer.
So you got acquainted with the technical characteristics, advantages and disadvantages of LED lamps. To finally prove to you that these products are the best among their competitors, we provide several comparison tables:
I would also like to note that in world practice, LEDs enjoy leadership in most countries. The exception is Japan, which still gives preference fluorescent tubes. Having knocked down the pros and cons, we can say that today LED lamps are in almost all respects better than other light sources.
