Power of modern energy-saving lamps. Power of LED lamps 6 W of LED lamp equals

In the practical choice of an LED lamp, it is inevitable to compare it with the light sources already available and familiar to us. Primarily with incandescent lamps. That is, you need to know how to compare the light of an LED lamp with the light of lighting lamps that are already familiar to us.

After all, LED lamps are bought in order to replace incandescent lamps, which means that lamps with a certain luminous intensity are needed. If you are used to having a 75 watt incandescent lamp in your kitchen, then you need an LED lamp that gives you the same amount of light. That is, the power of an LED lamp should be approximately equal to that of an incandescent lamp.

The problem is that over the long period of monopoly of incandescent lamps, we have been taught to incorrectly assess them on the scale of "weak - strong". Historically, such an estimate was made based on the power consumed by the lamp. That is, the lamps varied and were rated in watts. However, this was wrong.

Because we need a lamp in order to receive light. We need a luminous flux of a certain strength. How much power does it consume at the same time is the second question. While there were only incandescent lamps on the market, it made no difference how to evaluate them, even in parrots.

But today there are already several types of light sources available. And it became necessary to compare them with each other. And in terms of the power consumption of electricity, this cannot be done, because different types lamps it is different.

For example, LED lamps with a power of 100 watts are already industrial-type lighting (E40 base), for large areas. But a 100 watt incandescent lamp is just a household lamp for relatively small rooms. If you buy a 100 W LED lamp to replace a hundred-watt incandescent lamp, then you will not be able to use it in a household room - it will be too bright.

In other words, you cannot compare the wattage of an LED lamp in watts with the power of an incandescent lamp.

How to be?

For a very long time, since the creation of the first lamps, there has been a special unit of measurement specifically for lamps - lumen. This unit of measure indicates how much light the lamp produces, that is, how much light the lamp gives off.

Here is a short luminosity table for the most common incandescent bulbs:

• Incandescent lamp 25 W - luminosity 230 lumens (efficiency 9 lumens per watt).
• Incandescent lamp 40 W - luminance 415 lumens (efficiency 11 lumens per watt).
• Incandescent lamp 60 W - luminance 720 lumens (efficiency 12 lumens per watt).
• Incandescent lamp 75 W - luminosity 940 lumens (efficiency 12.5 lumens per watt).
• Incandescent lamp 100W - luminance 1350 lumens (efficiency 14 lumens per watt)

Remember these numbers - 230, 415, 720, 940 and 1350 lumens... And be guided by them when you choose an LED lamp. The packaging of LED lamps indicates not only their power (watts), but also their luminosity (lumens). See exactly the luminosity figure.

For comparison, the power table of LED lamps:

• Ikea Ryet 3W LED Lamp - 200 lumens (efficiency 67 lumens per watt).
• Phillips 4.3W LED lamp - 470 lumens (109 lumens per watt).
• Ikea Ryet 5.5 W LED lamp - 400 lumens (efficiency 73 lumens per watt).
• OSRAM 6W LED lamp - 470 lumens (efficiency 78 lumens per watt).
• OSRAM 10W LED lamp - 806 lumens (efficiency 80 lumens per watt).
• LED lamp Ikea Ryet 13 W - luminance 1000 lumens (efficiency 77 lumens per 1 watt).
• 10.5W Phillips LED lamp - 1055 lumens (efficiency 100 lumens per watt).
• OSRAM LED lamp 12 W - luminance 1055 lumens (efficiency 88 lumens per 1 watt).

Using two tables, we can get a comparison between the wattage of LED and incandescent bulbs.

Power table of LED lamps and incandescent lamps

• Incandescent lamp 25W - LED Ikea Ryet 3W, but the light will be slightly less, approximately like a 22W incandescent lamp.
• Incandescent lamp 40 W - LED Ikea Ryet 5.5 W, Phillips 4.3 W, OSRAM 6 W. The last two will actually give a little more light than a 40W incandescent lamp.
• A 60W incandescent lamp is a 10W OSRAM LED, but this lamp will give more light, about the same as a 65W incandescent lamp.
• Incandescent lamp 75 W - LED Ikea Ryet 13 W, Phillips 10.5 W, OSRAM 12 W. But all three will give a little more light, about the same as an 80W incandescent lamp.

As you can see from the three tables, most likely you will not be able to find an exact analogue, in terms of luminous intensity, for your incandescent lamp. But there are still no big differences in light intensity.

Averaged, the correspondence between the power of LED lamps and incandescent lamps can be expressed as follows:

• Incandescent lamp 25 W - the power of LED lamps is approximately 3 - 3.5 W.
• Incandescent lamp 40 W - the power of LED lamps is approximately 4.5 - 5.5 W.
• Incandescent lamp 60 W - LED lamps approximately 8 - 9 W.
• Incandescent lamp 75 W - LED lamps approximately 10 - 13 W.
• Incandescent lamp 100 W - LED lamps approximately 15 W.

It can be formulated even more briefly: LED lamps give comparable luminosity with a difference in power consumption of about 6-8 times.

The transition to energy-efficient resource use begins with understanding whether the 6 watt incandescent lamp and LED are equal. To do this, it is necessary to understand the principle of operation of light sources of both types, to see the structural differences in performance. For the convenience of consumers, tables have been developed for comparing the power of different types of light bulbs. There are methods for calculating the lighting of premises by their areas using LED lamps.

Structural differences

The advantages and disadvantages of various light sources are predetermined by the principle of operation and the device. Traditional bulbs have served people for many years, have several varieties, and LED bulbs appeared relatively recently, but are gradually replacing ordinary bulbs. The most common emitters today are:

LEDs first appeared in 1962 and their manufacturing technology was complex. Today, a lamp of this type consists of an integrated driver for stabilizing the supply parameters, a cap and several emitting diodes.

Products are connected to a 12 or 220 V network... The latter option assumes the need to rectify the current, since LEDs do not work from alternating current.

Power comparison

The main criterion for assessing the quality of a product (from a consumer point of view) is the power of a light bulb in watts. To understand the ratio of the indicator for different types of shining bulbs, you can refer to the table.

The table shows that LED lamps have the lowest power. The second largest energy is a tubular element of cold glow.

The traditional heating principle is the most inefficient in terms of efficiency: 6 watts<50 Вт - оба источника обеспечивают освещённость 550 лм.

The energy efficiency of an LED lamp, taking into account the direct dependence of the indicator on the power consumption, is 10 times higher than that of a conventional one. At the same time, the service life of the optical device is thirty times longer than that of a traditional incandescent source. There are also parameters by which lamps are compared:

According to all characteristics, a clear advantage is behind LED lamps. It only remains to add that their design is varied in shape (ball, candle, spiral) and colors. A relative disadvantage is the high cost, but it is completely leveled against the background of the superiority of the LED according to other criteria.

To select an LED analogue to a conventional radiation source, use power correspondence tables available for viewing on the Internet. The decision to replace is supported by the general recognition of the greatest safety of LEDs for humans in comparison with other sources. Looking in the passport of the device, you can calculate how many bulbs are required to ensure good visibility in the room:

For a corridor of 12 m² H \u003d 100 lx, and F \u003d 550 lm for a 6 W LED device. The required number of sources R \u003d 12 * 100/550 \u003d 2.2. using the rounding rule, you can take to install 2 LED bulbs of 6 W.

Another parcel arrived today to me, it went for a long time, tk. New Year's holidays are ahead, I already wanted to open a dispute, but everything worked out and my long-awaited light bulb is in my hands.
Without thinking twice, he immediately screwed it into the chandelier instead of Ilyich's burned out bulb. I liked the light immediately, well, in general, what I expected.

Now in more detail.
A bit of background. After buying LED lights and visible bright and effective light from them, I began to think about installing diodes at home. Having thought a little, I realized that trying to collective farm chandeliers with diodes myself is not the best idea. On the Internet, you can already see reviews of LED lamps. But it often turns out like this: people take these bulbs based on the minimum price and "try it anyhow" the first thing they see. Usually this is where there is more LED. The result, as a rule, is the same: seeing that this lamp shines like a light bulb for 15 watt, people convince themselves forever or for a very long time that LED lamps are generally weak, and they no longer risk taking an expensive one. Now I will try to convince everyone otherwise.
Since in my 4 chandeliers in the room there are 8 bulbs of 40 W each, my criterion was to buy LED bulbs with at least not less luminous flux power. Based on Wikipedia, I found that 40W \u003d 420Lm. Then I read several articles about LED lamps, in one of them I found a detailed description of the calculations of savings on LED lamps. There are a lot of interesting things about the payback period, but I will not go into details, google to help anyone interested.

The most important thing that I was able to extract from these articles is:
1. A good LED lamp should NOT be 20, 50, 100, etc. LED, i.e. too multidiode. Because The efficiency of these diodes is poor.
2. It is necessary to choose the right temperature of the light, for the house the light should be warm. This is about 2700-3500K.
3. Ilyich's lamp base is called E27.
4. Cooling is compulsory because diodes are heated very well. But here is how lucky.

Naturally, I didn't want to pay big money for the first light bulb, so the price factor was also open. Based on what was written above on the search on ebay, I liked this particular light bulb.

So what came out of the purchase:
1. I did not notice the difference in color temperature from ordinary bulbs; the color is just as warm and pleasing to the eyes.
2. The luminous flux by eye does not differ from a 40 W bulb (checked by alternately screwing in 1 bulb), which means that with the same brightness, its consumption is more than 6.5 times less.
3. Due to its design (photo below), the light bulb now illuminates the ceiling less, which means the luminous flux is directed to the desired area.
4. Declared MTBF of 50,000 hours. By the way, if you turn on the light bulb every day for 8 hours, then this is just over 17 years. I don’t know whether to believe these figures, but definitely if it works at least half of this, the savings will already be excellent.
5. Of course, this is just another interesting purchase!

The light bulb has already worked for several hours, I noticed that the radiator is heating up very much, it is impossible to hold on to it. However, everything works. Hope this is normal operation. It turns on with a delay of about a second.
Here is the actual photo

Dimensions
Those. About 49 mm.

Frosted glass can be easily unscrewed and this is what we see under it

I did not disassemble further, tk. saw that the thermal paste is present where needed.

It should be noted that LED technologies are constantly being improved. Now, by the way, I'm going to start looking for more powerful light bulbs equivalent to 60 and 75 watts. Although for a start I will buy 5 pieces.

Attention! I gave a link to the goods that arrived to me. The price I bought it at was $ 7.5. The light bulb was exactly as shown in the picture (with 5 diodes). Now the price has been reduced (but not the lowest) and it is possible that other bulbs will be sent. At the moment, the lowest one found at $ 6.39. Yes, and on it I am the 2nd going, as soon as it arrives - I will unsubscribe.

Update as of 18.02.2012
Carried out measurements and got the following results (! These are lamps for 5 diodes)
18.9V, 0.19A. This is approximately 3.6 watts. For warm light about 290 lm, which is closer to the Ilyich lamp of 30 W (if there was one). Definitely not enough. I do not recommend buying.

The main advantage of LED light sources is significant energy savings. You can get tangible and desired results using the products of the online store.

Energy-saving fluorescent lamps, which have already become familiar to many, are gradually becoming a thing of the past. Lighting equipment of a fundamentally new type comes to replace it, with different light and quality characteristics. Modern LED light sources have a whole range of advantages over their predecessors. This applies to light output, energy consumption, service life, environmental friendliness, fire and mechanical safety. The "minuses" that complicate their implementation include the higher cost and conservatism of some part of the population.

To overcome doubts, it is enough to turn to lED lamp power correspondence table characteristics of previous generation light sources.

Comparison table of characteristics of lamps: incandescent, halogen, energy-saving fluorescent and energy-saving LED lamps

Correspondence table of luminous efficacy of energy-saving (fluorescent) lamps and incandescent lamps corresponds

LED and incandescent

It should be noted that the tabular figures are average and may differ for. However, the conclusions are clear. Traditional, but morally outdated, uneconomical light bulbs lose significantly. The given table of correspondence of the power of LED lamps, even taking into account the inevitable error, convincingly proves the advantages of the new generation systems. To this must be added a long service life due to their design features and providing a quick and repeated payback. Analysis of tabular data, simple calculations show: the present and the future - behind LEDs!

Recently, many are thinking about switching to LED. If before there was one such parameter as power, now it is a full-fledged electronic lighting device with several basic technical characteristics, a power supply on microcircuits, light from warm to cold, and even three-color RGB.

Ignorance of the ratio of LED lamps and incandescent lamps is used by unscrupulous sellers and manufacturers, for example, indicating the brightness of 800 lumens and stating that it is analogous to a conventional 100 W incandescent.

Power ratio table

The table shows the power ratio for led bulbs for a house with open diodes, that is, without a bulb, which reduces the brightness by 15-20%.

The most common misconception is that a 10W LED is the equivalent of a 100W incandescent lamp. But taking into account the fact that the matte bulb reduces the brightness by 20% and 1W is spent on heating the driver, in the end we get only 7 useful watts, which will give 700-800 Lumens on average. That does not reach the required 1300 lumens at all.

An example of a matte flask

Powerful diode bulbs use a bulb to protect your eyes, especially children, because it is dazzling like welding.

An analogue of 100W incandescent will be two 650 Lumen diode lamps. When choosing, now you should not focus on Watts, but use the number of Lumens according to the correspondence table. The higher the brightness of the diode, the larger its radiator should be. This is one of the indirect ways to determine the cardinality and find the correct equivalent.

1. You can also find long LED G13 on sale, which can replace mercury in fluorescent lamps, keeping the current case.

2. If your lighting for the room has not yet been designed and installed, then in order to reduce the cost of lighting, you can install LED panels under the Armstrong ceiling. The panel measures 60 x 60 cm and is 1 cm thick without a power supply. It can be mounted on almost any ceiling overhead. In return, we get a huge brightness of 3600 lumens for 1250 rubles.

3. I prefer corn-shaped diode lamps, they are well-designed and do not require a separate heatsink for heat dissipation and bulb. The only drawback is the open electrical contacts of the diodes with low voltage.

Main characteristics

The main characteristics include the following indicators:

• lamp power, measured in watts (watts);
• luminous efficiency or light output (brightness), measured in lm / W (lumen / watt);
• color rendering index, measured in%.

What should be the illumination or how much light do you need to perform certain tasks? For this use the unit of illumination lx (lux). It shows the level of illumination, which is created by a luminous flux of 1 lm, evenly distributed over a surface of 1 m 2.

Illumination must comply with the standards established by legislative documents (SNiPs). It's not hard to check. To do this, it is enough to make simple calculations. It is necessary to calculate the total power of W lamps, which are either installed in a particular room, or it is planned to install, the resulting figure is multiplied by the light output of the lamps in lm (indicated in the lamp passport) and divided by the area of \u200b\u200bthe room in m 2. The obtained calculations are compared with the standard indicators.

Principle of operation

In incandescent bulbs, the light source is an e-conductor. current, made of refractory wire, which under its action heats up and begins to glow. The conductor itself is housed in a glass flask filled with an inert gas. To connect to the power source, there is a base, which is marked with E27 for a standard light bulb used in everyday life.

A kind of incandescent light bulbs are halogen lamps, which differ from the usual lighting devices only in materials and manufacturing technology. The addition of bromine or iodine vapor (halogens) to inert gases in the flask brings the color rendering index closer to 100% and increases light output. This advantage has been appreciated by car headlight manufacturers. On the road, factors such as subject clarity and illumination are important, which made it possible with the help of halogen lamps to realize these 2 important advantages in the production of car headlights.

Fluorescent lamps under the influence of el. current, a gas discharge is generated, which is emitted in the ultraviolet. This contributes to the glow of the phosphor, which covers the inner space of the bulb. In terms of service life, such energy-saving products exceed traditional incandescent lamps dozens of times. Currently, the range of manufactured lamps is extensive, they differ in the shape of the tubes, power and type of connection to the supply network.

In LED bulbs, the incandescent body is a semiconductor.When passing email. current, it generates optical radiation. In the pn transition region, part of the energy is dumped in the form of visible light. For the first time such a unique product appeared in 1962, since then its production technology has been improved, and today the market for these products is the most extensive. The effectiveness of LED lamps has been proven over time.

Correspondence table

LED bulbs outperform other types of bulbs in the following key areas:

• energy consumption;
• light output;
• heat generation;
• impact resistance;
• environmental friendliness;
• fire safety;
• service life.

Comparative characteristics of lamps by power

The table shows that the power consumption of LED products is the smallest, so this type of lighting fixtures are the most economical. How many lumens is in a lamp? This indicator depends on the power of the light bulb. The luminous flux is shown in the table.

The color of the luminous flux of LED products can be very different. It is determined by the chemical composition of the LED. Sometimes, for this purpose, different LEDs and light filters are installed in the lamp design, which makes it possible to obtain a glow in a wide spectrum range.

It is customary to compare bulbs according to the following indicators:

• degree of heating;
• anti-vandalism;
• service life.

In terms of structural strength, the most fragile are incandescent and halogen lamps. The LED bulbs are made of impact resistant material and can withstand low drops. The situation is worse with fluorescent lamps, although their body is much stronger than the body of incandescent lamps, but from an environmental point of view, its destruction has a detrimental effect on health. Therefore, they must undergo special disposal.

And finally, the service life, which is usually indicated in hours. The palm belongs to LED lighting fixtures again. In practice, their service life ranges from 25 to 100 thousand hours and it depends on the production technology, materials used and the manufacturer. Other types of light bulbs serve much less, for example, incandescent lamps - 1 thousand hours, halogen - 4 thousand hours, fluorescent - no more than 10 thousand hours.

What is the difference between spiral and diode products?

The technical features of each lighting device are determined by the design characteristics and the way of functioning. The principle of operation of an incandescent lamp is to set the temperature with a spiral at the time of electric current supply. To ensure the safety of using the device and supplying its uniform beams of light, this part is located in a special glass flask filled with discharged oxygen.

The standard type of spiral products has a very affordable cost, which, in fact, users considered as a way of saving. In this case, it is important to take into account the average operational life and the required amount of electricity consumption for the operation process.

With the ratio of the power of LED lamps and incandescent lamps, comparing the service life and other parameters, it is more economical to use the first option. Its design consists of a complete set of semiconductor diode devices, which are interconnected into one product. Each element is a crystal that produces photons as electricity passes through the device.

Incandescent lamps have only 2 clear advantages - the price and the direction of the flow, in all other respects they are far ahead of LED

Before the user decides on the choice, a comparative analysis should be made.

1. LED lamps consume significantly less energy for operation. Roughly, consumption is ten times less than the spiral product.
2. An incandescent lamp scatters radiation 360 ° C, which creates full illumination of the room, including walls, floor and ceiling. Most LED luminaires have a flat design with built-in light components. During the operation of the product, light is emitted at an angle of no more than 170 ° C.
3. The service life of semiconductor lighting devices is much longer. This factor is directly related to the reduced heating of the crystals, the temperature of which does not lead to destructive processes, which is quite characteristic of incandescent lamps.

How to calculate power matching?

It will not be entirely correct to select an LED lamp in terms of power, since these parameters indicate only the amount of electric current that lighting equipment requires to function. The main indicator for any lighting equipment is the efficiency of the light beam, which is measured in lumens (Lm).

Approximate figures indicate that the power of the spiral models of 100 watts is equal to the performance of lighting with an intensity of 1200-1400 lumens. The difference between the indicators depends on the degree of transparency of the case.

In order for the LED device to be able to produce these values \u200b\u200bduring operation, its power should not exceed 14 W. Often, consumers calculate the equivalent in terms of energy consumption, this is done due to the fact that not all manufacturing companies indicate the efficiency of the light beam on their products.

For this reason, for a more correct comparison, it is necessary to take into account the ratio of the power of LED lamps to spiral products.

The required power value will not always correspond to the standardized parameters of the product. In this case, it is recommended to install several diodes instead of one. Thus, in total, they form the luminous intensity of the desired coefficient.

LED power table:

In addition, other comparative parameters should be taken into account, including the scattering angle. The criterion determines the area that is supposed to be illuminated.

To fully illuminate the room, experts recommend installing diode devices made in the shape of a pear.

Please be aware that this series may not be suitable for all lighting fixtures. The product can be replaced by a semiconductor device with a flat area with a scattering angle of not more than 170 ° C.

It is important to remember that the more diodes are present in the device, the brighter and more uniform the light will be, but the cost of the device will also increase. Modifications with 4-8 diodes are often purchased, resulting in 10-14W.

VIDEO: The real ratio of the amount of light from incandescent lamps and LED lamps

To replace uneconomical incandescent elements with diode devices, it is necessary to determine the base of the desired device. This requires measurements of the depth and diameter of the cartridge. Next, you need to follow the following recommendations:

1. No need to rely on the power of the device being replaced. Use the auxiliary look-up table above.
2. Luminous flux is an equally important nuance when choosing a light fixture. It is necessary to compare the luminous flux of devices with the same operating angle.
3. Scattering angle. To illuminate the entire room, a light source with an illumination angle of 170 ° C will suffice. The option allows you to illuminate the floor and walls, while leaving the ceiling darkened. For wall-mounted or tabletop products, it is better to use lighting equipment with a small illumination radius.

1. Light temperature. You should know that the temperature regime must correspond to the purpose of the room:

• at a temperature of 4000-5000 ° K, daylight awakens vigor, disposes to work, does not blind the eyes, is used in offices;
• 2500-3500 ° K - warm light has a beneficial effect on the comfort of psychological relaxation, it is used in the bedroom, living room, etc.

With all the variety of light elements, the overwhelming majority of them are produced with a screw-type base - Edison's screw. And already among the first places are divided, respectively, by E14 and E27, which operate from a 220V network. In this marking, E stands for type (Edison Screw), and the digital combination stands for the base diameter (chuck width).

Main characteristics of lamps

The comparison was made between an ordinary 75 W incandescent lamp and its equivalent - a 9 W LED lamp. You can read more about the main characteristics of incandescent lamps here, and LEDs are described in this article.

Incandescent lamp:

• declared lamp power - 75 W;
• required voltage - 230-240 V;
• heating temperature - 2700 K (2426.85 ° C);
• luminous flux - 935 lm;
• luminous efficiency - 12.5 lm / W;
• scattering angle - 360 °;
• average work life - 1000 hours;
• dimensions - 50 by 88 millimeters;
• guarantee - not provided.

LED lamp:

• the declared lamp power is 9 W;
• required voltage - 170-240 V;
• heating temperature - 2700 K (2426.85 ° C) ;;
• color effect - warm white light;
• luminous flux - 800 lm;
• luminous efficiency - 88.8 Lm / W;
• dispersion angle - 240 °;
• average work life - 40,000 hours;
• dimensions - 60 by 110 millimeters;
• warranty - 2 years.

In many respects, an LED lamp looks more attractive than a conventional spiral light bulb. Such properties are provided by various designs. In an LED lamp, electrical voltage makes an inert gas glow, and the electricity does not need to overcome additional resistance.

The efficiency of such lamps is much higher - 98% versus 65% for a conventional incandescent lamp.

Wattage of LED lamps and incandescent lamps

It makes sense to compare two types of lamps and according to their key parameter - the power of incandescent and LED lamps. That is, this electricity, which is converted into light.

The most significant advantage of LED lamps is their energy efficiency, which surpasses all analogues. So, one LED lamp consumes only 6 W of power at a similar luminosity, a fluorescent lamp - 12 W, and a conventional incandescent lamp - 60 W.

A simple example: if you need to illuminate a room with 3 lamps, then the total energy that will be consumed by standard bulbs is 180 W, while 3 LED lamps will only "eat" 18 W. That is, there is a 10-fold savings! And the light level is the same. Moreover, the spectrum of an LED lamp is more natural in comparison with an incandescent lamp, which "turns yellow".

Therefore, you can safely count on a decrease in the monthly rent at the same level of illumination.

For convenience, the correspondence of power consumption at the same illumination level can be presented in the following table:

To put it simply, we can say the equivalent of a LED lamp to an incandescent lamp in a ratio of 1:10. That is, if you need to replace an incandescent lamp with an LED lamp of a similar luminosity level, then you need to reduce the declared power of the incandescent lamp by 10 times and brother the LED lamp with the obtained indicator.

Outcome

Thus, the LED lamp is not just an analogue of an incandescent lamp, but is ahead of it in many key indicators: in terms of power consumption, the ratio of luminosity and energy absorption, and service life. It makes it much easier to fit into the lighting standards.

Certified lamp manufacturers provide a warranty to protect buyers from factory defects.

Another significant advantage of LED lamps is the use of aluminum and special heat dissipating plastic as absorbers of excess heat. This allows the room and the light bulb itself to heat up less, respectively, increasing its service life.

In theory, the LED lamp can operate for 3 years in continuous mode. And if you turn it on for 2-3 hours a day, then the duration of its work will be more than 36 years.

Recently, it has become popular to talk about the dangers of LED lamps, but this only applies to cheap low-quality models. More on this here.

The luminous flux in LED lamps is limited to 240 degrees, which allows the light to be directed concentrated downward or to the side, avoiding scattering in all directions and avoiding light and heat losses. This indicates that the LED lamp can be successfully used in small rooms such as a pantry or closet.

LED lamp: design and main technical characteristics

LED lamp is a light source, the radiation of which is carried out due to the use of several LEDs in the structure, connected in one circuit. Unlike other types of lamps, it does not use a tungsten filament, various gases, mercury and other components that are dangerous to human life. It is an environmentally friendly device that does not emit harmful substances during operation and failure. According to its energy-saving indicators, it is the most economical among analogues. Can be used to illuminate streets, industrial or residential buildings and premises.

The design of this light bulb consists of the following elements: diffuser, LEDs, circuit board, radiator, power supply, housing and base. The last element can have two standard sizes of the cartridge: E14 (small) and E27 (large).

When choosing, you must be guided by the values \u200b\u200bof the main characteristics:

• Luminous flux, measured in lumens (lumens). The amount of light that travels in all directions from the light source.
• Power, unit of measure W. The amount of energy consumed per unit of time.
• Luminescence color temperature, unit of measurement K. Determines the color of the luminous flux emitted from the radiation source. Incandescent lamps are mostly 3000K, this is a "warm", yellowish tint. LED light sources are different, from 3000K to 6500K ("cold" color, with a slight admixture of blue).
• Light output, measured in lm / W. A characteristic that determines the efficiency and economy of a light source. Products from different manufacturers, of course, are different.
• Heating temperature, unit of measure ° C. Indicates the operating temperature for heating the glass surface of the lamp.
• Service life, measured in hours. Determines the maximum service life under the optimal conditions stated by the manufacturer.
• Color rendering index, CRI. Measured from 0 to 100 points. For optimal human perception of color rendering from a light source, the more points, the higher. 80 CRI is considered normal.

Two LED lamps with the same wattage may differ in luminous flux and temperature.

This type of energy-saving light bulb can be produced in two types: standard (pear-shaped) and in the form of "corn". This factor must be taken into account when replacing the light source in the luminaire. The latter type is not recommended to use, since in this design the LEDs are located on the outside.

Comparison of LED bulbs and incandescent bulbs

For domestic use, a person uses an LV with a rated power of 40, 60, 100 W. Let's analyze the correspondence of LED lamps to incandescent lamps. The results are presented in a correspondence table. From the data carried out, it follows that the declared LN corresponds to the power of LED lamps of 5, 7 and 13 W, which is more than 8 times less.

The rest of their technical indicators are practically equivalent. The obvious advantage of SLs lies in their power consumption and durability. Thus, replacing an ordinary light bulb in a luminaire with this energy-saving light source is economically justified, which is primarily confirmed by the ratio of LED lamps and incandescent lamps.

Basically, lighting is used at night, when a person is at rest and rest. For these conditions, soft (warm) lighting is considered favorable. This corresponds to a color temperature of 2100–3500 K. Therefore, the emitted yellowish light from the LN is better suited than the white from the SL. In the light flux emitted by the LED, there is a blue color, which has a negative effect on human vision, especially on the unformed lens of the child's eye. Light bulbs with a blue spectrum in their radiation are recommended for lighting workplaces in an office, as they stimulate human activity and productivity. Also, the flickering of LED lamps has a negative effect on the optic nerve. This is due to the poor build quality and component parts of the power supply, as well as power surges and surges.

Before purchasing SL, make sure that the luminous flux ripple is not more than 5%.

When choosing an alternative light source, it is necessary to be guided not only by the power of LED lamps and incandescent lamps, but also by other technical characteristics and factors. The high price for the SL is compensated for by the subsequent savings in money for the payment of consumed electricity and a long service life. And the absence of a high heating temperature of the outer surface and the release of harmful substances into the environment during operation increases the safety of products.

Conclusion

To save energy, there are alternative light sources to incandescent lamps - LED lamps. This article summarizes the main characteristics that affect their use. Above is a table comparing the wattage of incandescent and LED lamps. When choosing a light source, you also need to consider performance. We hope this article will help you make the right decision.

LED lamp power.

Lighting devices that have existed for more than one century are constantly being improved.

This is especially noticeable in the last decade. At first, incandescent lamps replaced carbon lamps, then fluorescent lamps appeared, and today energy-saving and LED lamps are quickly penetrating into our lives.

What is the quality of the light output of LED lamps?

LED lamps have appeared relatively recently, their cost is still quite high.

However, their popularity is constantly growing due to their main advantage - significant energy savings.

After all, with the same power consumption, an LED lamp will provide a luminous efficiency almost eight times higher than a conventional incandescent lamp.

So, a 3 W LED lamp is equal in luminous efficiency to a 25 W incandescent lamp, and a 10 W LED lamp is equivalent to an 80 W incandescent lamp.

At the same time, the development of technology is increasingly bringing LED lamps closer to natural light in terms of the quality of light emission.

LEDs as light sources.

LED lamps began to triumphantly replace the fluorescent energy-saving lamps that have already become familiar to many.

The new LED lamps are lighting fixtures created using a light source built on completely new principles, and with much better quality and light characteristics.

The most modern light sources based on LEDs demonstrate a whole range of advantages over their predecessors, including increased light output, reduced energy consumption, longer service life, environmental friendliness, high mechanical and fire safety.

The only drawback today seems to be their rather high cost. In addition to the cost, the rapid introduction of LED lamps into everyday life is somewhat hampered by a certain conservatism of the majority of people.

Power of LED lamps, table of comparative characteristics.

Comparing different types of lamps will help to overcome doubts about choosing LED lamps. There are many comparative tables, after studying which, you can understand that LED lamps really give more light with less electricity consumption (see table).

So, a 3 W LED lamp is equal in light emission to a 15 W fluorescent lamp or a 25 W incandescent lamp, and a 10 Watt LED lamp is equivalent to a 50 Watt energy-saving lamp or a conventional 80 Watt light bulb.

The power of LED lamps, the table of which clearly demonstrates the advantage of these devices, usually does not exceed fifty-five watts, however, the light emission of a lamp of this power will correspond to almost four hundred and fifty watt incandescent light bulbs. At the same time, the heat release will be an order of magnitude less, which means that LED lamps have the highest efficiency among existing lamps.

However, it is necessary to pay attention to the fact that all tables of the power of LED lamps are filled with averaged figures, which may differ slightly for each specific product.

However, these differences are not so big as to prevent an unambiguous conclusion about the complete loss of traditional, uneconomical and obsolete light bulbs.

What is the power of energy-saving fluorescent lamps?

The same can be said about energy-saving fluorescent lamps, which, although not to the same extent as incandescent lamps, are still significantly inferior to LED lamps. After all, it is absolutely real that a 3 W LED lamp is equal to a 25 watt incandescent lamp in terms of luminous flux, and a 10 watt LED lamp is the equivalent of the most common 80 watt incandescent lamp.

In addition to efficiency, LED lamps have one more important advantage - they are maintainable, which means that their efficiency increases even more.

Matching LED bulbs and incandescent bulbs

LED bulbs consume less power than traditional incandescent bulbs. So an ordinary light bulb with a need for 60 watts in brightness will correspond to an LED lamp with a power of 9 watts, therefore, the power consumption will be less.

As a comparison, we offer a table that will help you understand the ratio of two bulbs.

Attention! The table will help you make an effective replacement of lighting: from incandescent lamps to LEDs.

Table No. 1 Power of compared light sources

From this table, we see the difference in the wattage of lamps with the same light intensity, and the savings in favor of LED lighting.

How to choose LED outdoor lighting?

If your plans include replacing incandescent bulbs with LED bulbs in the yard, it is important to consider several factors:

• traditional outdoor lamps have a power of 250 watts, and to replace such lighting, one E40 LED and 30 extra-bright elements are enough. The total capacity of all this equipment will be 30 watts;
• for outdoor conditions, bulbs can be used with low power, but they will shine quite brightly;
• it is important that lighting resists environmental influences;
• try to choose lighting fixtures only from rated manufacturers. When buying LEDs, ask for a product certificate.

What is important to know when arranging LED lighting for your home?

Indoors, devices with an E 47 base are most often used as LED bulbs. Such LEDs are found in various models, they are often used in the form of a ball, pear or candle.

Homes are often equipped with traditional lighting with a power of at least 100 watts, since they give off a higher luminous flux. If we take the correspondence of the power of incandescent and LED lamps, we can say that the alternative is just a source with a power consumption of 3.2 watts, that is, an LED. Therefore, financial savings are created up to 31 times.

When choosing the type of lighting for your own home, it is important to compare all popular equivalents. For example, incandescent lamps have many disadvantages, ranging from a short lifespan to the fragility of the material. The LED equivalent does not contain mercury and does not break, even if it falls on a concrete surface. It is possible to replace one traditional lamp in a multi-lamp luminaire with several LED bulbs and gain in brightness. In addition, the light will become multidirectional and uniform.

Attention! LED lighting is recognized as the safest and most harmless to humans in comparison with other light sources.

The cost of LED lighting is quite high, however, it quickly pays off, since electricity is spent several times less.

Calculation of LED lighting

The ratio of watts of LED lamps to incandescent lamps leads to the fact that better savings cannot be found. Therefore, before making the purchase of LED equipment, everything must be properly calculated.

1. Look at the technical data sheet for the device. It indicates all the values \u200b\u200brequired for calculations. We use an indicator of light brightness or luminous flux.
2. We determine the area of \u200b\u200bthe room in which it is planned to install LED lighting.
3. Now we multiply the number of square meters by the illumination value of the room indicated in the SNIP, and then divide the resulting value by the luminous flux in lumens, which we took from the instructions for the lamp.

R- calculation of room illumination by LEDs;

P is the area of \u200b\u200bthe room;

X is the standardized value of SNIP;

Y is the luminous flux of the device, lm.

Example of formula calculation

Suppose you need to find calculations for a small room. Here we know the area is 13 sq. m is a corridor. The SNIP rate for this room is 100 Lux, the luminous flux of our bulb is 400 lm, which means R \u003d 13 * 100/400 \u003d 3.25. From the obtained value, we conclude that we need 3, and preferably 4 such bulbs.

Important! When installing LEDs, beware of open electrical contact.

How to replace an incandescent lamp with an LED?

Today it is practically not difficult to replace an incandescent lamp with an LED, as most sources are sold with a suitable base. Therefore, it is enough to simply screw in the LED lamp.

In some cases, it is necessary to resort to changing equipment, which is quite expensive. Carrying out a complete replacement of electrical wiring along with lighting, it is necessary to purchase point LED devices.

Important! Use LED lamps in optimal conditions. Remember that they must have time to cool down by their own mechanism.

Benefits of using LED lamps

Thanks to the following qualities of LEDs, they have received the title of a demanded light source:

• application is concentrated in absolutely any industry;
• gives off a large amount of light;
• has little power;
• made of durable material;
• environmentally friendly device;
• does not lend itself to accidental mechanical stress (if the fall does not break).

Of the shortcomings, only high cost is distinguished, but it also pays off well over time.
