Characteristics and types of LED lamps

In recent years, very popular LED light sources.The fact is that these lamps can be used in a variety of conditions, and the quality and brightness of the light is significantly higher than that of incandescent lamps.

sources is not a secret that LED lamps are actively incorporated into automobiles, machine tools and many other devices.Today, LED lighting in homes are not used very often, but we can say with confidence that in many aspects it is much better than fluorescent.

Moreover, LEDs - these are the best options for decorating the space.We can confidently prove that with the help of these tools you can really successfully decorate the room, even if it has a number of drawbacks.For a long time the LEDs are used for decoration and illumination of suspended ceilings and plasterboard structures.

In this article we analyze the main characteristics, advantages and disadvantages of modern LED lamps.Running a little ahead, you can say with certainty that the luminaires with LEDs - the best option for the home and for any other places.

main features of LED lights

It should be noted that many people do not recognize the LED lighting for the reason that they have a very bright light, and in the home often prefer dim lighting, which does not irritate the eyes.However, you need to know that LED bulbs are quite flexible color temperature.Of course, to find in stores dim LEDs is not so easy, but nothing is impossible.Preferably LEDs are built into lamps, it is known, should be as bright.

Of course, as a replacement for fluorescent lighting is a good option, but you need to pay attention to the fact that it is often necessary to make a complete replacement caps.This obviously attracts not all, especially if it comes to light large spaces, including industrial.

If you look at the range of products most stores, you can understand that it is often on sale can be found spotlights.They are small in size, and, as already mentioned, are used for installation in suspended ceilings.However, as the main lighting of the room - it is not the best option.Large funds are referred to as light projectors, but they are not used in indoor spaces.

specifications of LED lamps

First of all, it is necessary to determine the characteristics of LED lights, and only then make a choice in favor of one or another product.

• power consumption of lamps: 3 to 20 watts.
• Hue color emitted from 2700 to 6700 K.
• execution type: E14, E27, G5, G13, GU4, GU5.3.
• Voltage: 12V DC, and to 220V AC.

In addition, you should pay attention to the fact that many of the fixtures support brightness adjustment function of light.This feature is especially needed in terms of electricity savings in a large number of fixtures.

Distribution - this is another important aspect that you need to focus.Many spotlights, despite the external similarity, may cover a different area.Of course, this is indicated in the luminaire performance.

Well, it should be noted separately design of the lamps with LEDs.Accordingly, it is possible to find an overhead light sources, shear, embedded, and many others.Depending on the characteristics of the lamps can be used in a variety of conditions, from housing to industrial shops.

At home, often using cap type E27.He has the most suitable characteristics and dimensions for easy installation in apartments.If we talk about the lampshades and lamp, here it is best to use E14.Smaller versions of illumination found in microwave ovens, and even refrigerators.Here the decisive factors are the dimensions of the lighting and brightness.

Cap E40 is most commonly used for street lighting and industrial buildings.Accordingly, it is the largest version which can be found in the free market.

If there is a need to replace the fluorescent tubes, should be used with two-pin sockets contacts.

As we have said, most of LED lights embedded in the ceilings.We are talking about versions caps, labeled as GU4, GU5.3, GU10, and GU13.In this case, a voltage of 12 to 24V, so the cap conclusions are extremely thin.

analysis of power consumption

have already mentioned that the lighting power - this is quite a serious issue, particularly in an environment where taken into account every kilowatt of energy.The fact is that LED lamps are very often used in the industry.Accordingly, such means of illumination can be several hundred or even thousands.In such circumstances, even before the acquisition of fixtures, it is necessary to make detailed calculations, allowing to understand what will be the consumption of electricity.

Obviously, LEDs significantly more economical than many other means of lighting which are in use today.The large scale of their use - this is the most viable option that allows you to save tens of thousands of rubles.

At home, if we replace all incandescent bulbs to LEDs, you can also experience substantial savings.This is especially important if we take into account the ever-increasing electricity tariffs.

Well, the end is worth noting that determine the degree of brightness or lumen output does not work, even if there is a known power consumption.

Experts advise to pay attention to the power consumption in the first place, because it is from this characteristic depends on what matters to consumers.

AC and DC current source

themselves LEDs, built in lamps, working on direct current voltage of 12V.Thus it is necessary to know that there are often special schemes in drivers who spend a voltage to the very source of light.Accordingly, the front driver may be a connection to an alternating current voltage of 220V to the most common outlet.You can also find options with DC and AC voltage of 12 to 24V.

Before buying lamps, of course, is to clarify the issue of the current source.If the choice is made incorrectly, the LED can simply burn out, and thus the money spent will be impossible to recover.

If the LED bulbs have a driver, there is the risk of burning out the light source is extremely low.Such lamps often easy to carry any voltage drop.

It is also interesting that the differential voltage LED lamps hardly change their brightness.This is one of their advantages over incandescent lamps, which in similar circumstances can dim or blink rapidly.

power light emitting

Many owners who want to buy LED bulbs, interested in light emission power.This value is measured in lumens.To determine this value, it is necessary to know the ratio of A to Watts.

Compared incandescent bulbs with LED light sources, that often we have between 10 lm / W.Most conventional LEDs are used in home environment, which have a high efficiency - from 70 to 90 lm / W.

There is a table with the help of which you can compare the luminous ceiling light bulbs and LED light sources:

If you get a LED lamp in an ordinary store, manufacturers often do not indicate on the package immediately and efficiency, and light output.Accordingly, in this situation, we need to establish the necessary information personally.

Color Temperature

As mentioned earlier, it is this characteristic pay attention to people who are hesitant to switch to LED lamps.Unlike all the same common incandescent lamps, LED lamps have a really wide range of emitted light.Accordingly, we only need to know what to degree for the color we need.You can use the following scheme:

We also talked about the fact that most of the market can find a bright color options.The fact is that the LEDs for many people, are a good substitute for incandescent lamps because the bright fluorescent colors.Accordingly, if there is a need to dim the LEDs, it is best to do the order via the Internet, either directly through the manufacturer.

In general, to navigate, to remember the following values:

• about 2500K (Kelvin) - the temperature of a yellow glow;
• about 5000K - daylight white color;
• more 6000K - cool blue color.

Speaking directly about the practical application of LED, then, of course, for the home environment yellow glow is best suited, and for industrial buildings - other options.

In that case, if the tiny LED bulbs, built-in suspended ceiling, that is fine and white.

Adjustable brightness

Unlike many light sources, which are gradually fading into the past, LED lights can be equipped with devices called dimmers.With their help, you can adjust the brightness of the light.In this case, only diode blink frequency varies, no discomfort but it will not cause the human eye.

Adjustable brightness lamp - it really is an important point, which allows you to set the most comfortable light in the house, and do not forget about the energy savings.Though will not save a lot, but some effect on the dimmer will still be.

Unfortunately, not all LED lights are succumb to adjust the brightness.In some cases, the built-in drivers do not allow the bow of the installed operating frequencies.Obviously, the lamp that supports brightness adjustment, are more expensive than usual.Accordingly, if there is no need for a flexible configuration, the brightness, the better from this venture simply refuse.

light direction

Unlike incandescent and fluorescent light sources, LED lamps emit light in one direction only, but still a small sector in front of him.This, of course, a significant drawback, especially when it comes to the use of LEDs at home.

On the other hand, if we take into account the distribution of heat from the lamp, the LEDs are much more attractive.Often, the heat goes in a direction opposite to the light flux.Accordingly, it allows without any problems using this light source for stretch ceiling, which in other circumstances is melted and becomes unusable.

for uniform illumination of the entire room will take a few spotlights mounted on the whole room area.

Disadvantages of LED light sources

As it became clear from the above information, LEDs have many advantages that are likely to lead to the complete exclusion of obsolete lighting options.Despite this, LEDs have some disadvantages.

• price question.Unfortunately, to buy LED bulbs are not solved everything.The fact that the price tags are sometimes deterred buyers.One LED lamp is a dozen light bulbs.In such circumstances, the choice is obvious.
• The impact on human health.Some experts argue that the LED lamp is not the best way affect human health.Unfortunately, it is impossible to determine whether this is true, but on the Internet you can find the whole article devoted to the negative effects on human health LEDs.
