Lightweight light sources are very popular. The thing is that such lamps can be used in a wide variety of conditions, while the quality and brightness of the lighting is significantly higher than that of the incandescent lamps.

It is not a secret that the LED lamps are actively embedded in cars, machines and many other devices. To date, LED lighting in housing is not used as often, however, it is safe to say that in many aspects it is much better than luminescent.
Moreover, LEDs are the best options for decorating the premises. It is safe to show that with the help of these funds, you can really well decorate the room even if it has a number of flaws. For a long time, the LEDs are used to decorate and illuminated stretch ceilings, as well as plasterboard structures.
In this material we analyze the main characteristics, advantages and disadvantages of modern LED lamps. Looking a bit in advance can with confidence say that the lamps on the LEDs are the most optimal option for the home, and for any other places.
Main features of LED lamps
It should be noted that many people do not recognize LED lamps for the reason that they have too bright light, and in dwellings often prefer dim lighting, which does not irritate vision. However, you need to know that the LED lamps have a fairly flexible color temperature. Of course, it is not so easy to find in stores in stores, but there is nothing impossible. Mostly LEDs are embedded in lights, which are known to be as bright as possible.
Of course, this is a good option as a substitute for fluorescent lighting, but it is necessary to pay attention to the fact that it is often necessary to fully replace the caps. This obviously attracts not all, especially if we are talking about the lighting of large rooms, including industrial.
If you look at the product range of most shops, you can understand that you can find point lamps often on sale. They have small sizes, and, as already mentioned, are used to embed in stretch ceilings. However, as the main lighting of the room is not the best option. Large lighting facilities are referred to as spotlights, but they are not used inside indoor rooms.
Characteristics of LED lamps
First of all, you need to decide on the characteristics of LED lamps, and only then make a choice in favor of a particular product.
- Power consumption Lamps: from 3 to 20 watts.
- Tint of emitted color: from 2700 to 6700 K.
- Type of execution: E14, E27, G5, G13, GU4, GU5.3.
- Voltage: from 12V permanent, and up to 220V variable.
In addition, it is worth paying attention to the fact that many lamps support the function of adjusting the brightness of light. This feature is especially necessary in conditions of electricity saving with a large number of lamps.
The distribution is another important aspect that needs to focus. Many point lamps, despite the external similarity, can illuminate different areas. Of course, this is indicated in the characteristics of the lamps.
Well, separately, it should be noted the structural execution of lamps with LEDs. Accordingly, you can find overhead light sources that cut, embedded and many others. Depending on this characteristic, the lamps can be used in a wide variety of conditions, starting by the housing and ending with industrial workshops.
At home, the type of soccer E27 is often used. It has the most suitable characteristics and dimensions for convenient embedding in apartments. If we talk about lampshades or nights, then it is best to use the E14 base. Smaller lighting options are found in microwave ovens and even refrigerators. Here, the decisive factors are lighting dimensions, as well as brightness.
The E40 base is most often used to illuminate streets or industrial buildings. Accordingly, this is the largest option that can be found in a free sale.
If there is a need to replace fluorescent lamps, the bases with two contact conclusions should be used.
As we have already spoken, most often LED lamps are embedded in stretch ceilings. We are talking about the performances of the caps, marking as GU4, GU5.3, GU10, and GU13. In this case, voltage is used from 12 to 24V, so the conclusions of the base are extremely thin.
Power consumption analysis
It has already been mentioned that the lighting capacity is a fairly serious aspect, especially in conditions when every kilowatt energy is taken into account. The thing is that LED lamps are very often used in industry. Accordingly, such lighting tools may be several hundred, or even thousands. In such conditions, even before purchasing lamps, it is necessary to make detailed calculations that allow you to understand which electricity consumption will be.
Obviously, LEDs are significantly more economical than many other lighting tools that are used today. On a large scale, their use is the most acceptable option, which allows you to save tens of thousand rubles.
At home, if you replace all incandescent bulbs on LEDs, you can also feel significant savings. This is especially important if you take into account the ever-growing electricity tariffs.
Well, it is worth noting that determine the degree of brightness or the power of the light stream will not work, even if the power consumption is known.
Experts advise you to pay attention to power consumed primarily, since it is from this characteristic that what worries conventional consumers.
Variable and permanent current source
The LEDs embedded in the lamps themselves work on a constant current with a voltage of 12V. At the same time, it is necessary to know that there are often special drivers in the schemes that spend the voltage to the source itself. Accordingly, the driver can be connected to a variable current with a voltage of 220V to the most ordinary outlet. You can also find options with constant and alternating voltage from 12 to 24V.
Before buying a lamp, of course, it is worth clarifying the question of the current source. If the choice is incorrectly, the LED can simply burn, and at the same time the money spent will not be able to return.
If the LED lamps have a driver, then here the risk of light source is extremely low. Such lamps, most often, easily carry any voltage drops.
It is also interesting that when voltage drops, LED lamps practically do not change their brightness. This is another advantage of their advantage compared to incandescent lamps, which in similar conditions can fade or blink dynamically.
Power of radiation light
Many owners who want to buy LED lamps are interested in the power of light radiation. This value is measured in lumens. In order to determine this value, you need to know the ratio l to W.
If you compare incandescent lamps with LED light sources, then, often, we have from 10 to LM / W. The most common LEDs that are used at home have a much higher efficiency - from 70 to 90 lm / W.
There is a table with which you can compare the luminous ceiling of incandescent lamps and LED light sources:
If you acquire a LED lamp in a regular store, then often manufacturers do not indicate the packaging immediately and efficiency, and the power of the light flow. Accordingly, in such a situation, we will need to personally install the necessary information.
Colour temperature
As mentioned earlier, people who decide to switch to LED lamps pay attention to this feature. Unlike all the same incandescent lamps, LED lamps have a truly wide range of emitted light. Accordingly, we need only to know what kind of degree color we need. To do this, you can use the following scheme:
We also talked about the most often on sale you can find bright color options. The thing is that LEDs for many people are a good replacement of incandescent lamps due to bright daylight. Accordingly, if there is a need for dull LEDs, it is best to place an order via the Internet, or directly through the manufacturer.
In general, to navigate, the following values \u200b\u200bshould be remembered:
- about 2500K (degrees Kelvin) - the temperature of yellow luminescence;
- about 5000k - white daylight;
- more than 6000k - cold blue color.
If you speak directly about the practical use of LEDs, then, of course, a yellow glow is best suited for home conditions, and for industrial buildings - other options.
In the event that tiny LED lamps are embedded in the stretch ceiling are used, and white color is completely suitable.
Ability to adjust brightness
Unlike many light sources, which are already gradually leaving in the past, LED lamps can be equipped with devices called dimmers. With their help, you can adjust the brightness of light. In this case, only changes the frequency of the diode flashing, however, it will not cause any discomfort for the human eye.
The ability to adjust the brightness of the lamp is a really important point that allows you to set up the most comfortable light in the home, as well as not forget about the economy of electricity. Although it will not save much, but there will be some kind of effect from Dimmer.
Unfortunately, not all LED light sources can succumb to brightness. In some cases, embedded drivers do not allow you to spare from the installed frequency of work. Obviously, lamps that support brightness adjustment are somewhat more expensive than normal. Accordingly, if there is no need for a flexible brightness setting, then it is better to refuse it from this ventiy.
Direction of light flux
Unlike incandescent lamps and fluorescent light sources, LED lamps emit light only one way, and even in a small sector ahead. This, of course, a significant drawback, especially if we are talking about the use of LEDs at home.
On the other hand, if you take into account the spread of heat from the lamp, then the LEDs are much more attractive. Often, heat leaves in the direction opposite to the light stream. Accordingly, this allows without any problems to use this source of light for the stretch ceiling, which in other conditions melts and comes in disrepair.
For uniform illumination of the entire room, several point lights mounted on the entire area of \u200b\u200bthe room will be required.
Disadvantages of LED light sources
As it became clear from the above information, the LEDs have many advantages, which is most likely to lead to full displacement of obsolete lighting options. Despite this, LEDs and some disadvantages have.
- Price issue. Unfortunately, not everyone is solved to acquire LED lamps. The fact is that price tags sometimes scare buyers. One LED lamp is as a dozen incandescent lamps. In such conditions, the choice is obvious.
- Impact on human health. Some experts argue that LED lamps do not give the best way to human health. Unfortunately, so far it is impossible to establish whether it is true, but on the Internet you can find entire articles on the negative impact of LEDs on human health.
