LED characteristics: current consumption, voltage, power and light output. New energy: which garland is better? Energy consumption during the New Year holidays – by population

Good day, dear friends! Today we’ll talk about saving electricity again, in previous articles we calculated how much electricity household appliances (vacuum cleaner, microwave) consume, and today we’ll try to calculate how much electricity light bulbs consume in your home, and whether it’s possible to somehow save on electricity consumption by light bulbs.

So, let’s first figure out what kind of light bulbs we have in our apartment; the following types are most often used in everyday life:

  1. Incandescent
  2. Luminescent (energy saving)
  3. LED

Incandescent lamps

Let's calculate how much electricity is consumed by ordinary light bulbs of different wattages, the most popular ones in everyday life.

Power consumption:
Power 60W - energy consumption will be 60 W or 0.06 kilowatts per 1 hour
Power 95W - consumes electricity 95 W 0.095 kilowatts per 1 hour
Power 100W - will consume 100 or 0.1 kilowatt W of electricity in 1 hour.

To convert electricity from watts to kilowatts, you need to count 3 digits from right to left and put a comma in front of it, if there are only two digits or 1, then put 1 or 2 more zeros in front of this digit. For example, 75W = 0.075 kW since the numbers 2 were added 0 to move them by 3 digits. 7 W = 0.007 kW, for 155W = 0.155 kW.

Let's calculate how much we will pay for the use of light if, for example, we have 3 acres (hall, kitchen, bedroom) and 3 for 60 W (hallway, toilet, bathroom).

How much electricity do we spend?

Let's take for example 3 at 100W burn for 5 hours in the evening and 1 hour in the morning, resulting in 6 hours a day, we get 3 pieces per hour winding 300 W in 6 hours 1800W or 1.8 kW.
3 more at 60W, let’s assume that each burns for 1 hour a day, in total we get 3 * 60 W = 180 W or 0.18 kW. Total per day is about 2 kilowatts.

Heat calculator SPT

When using incandescent lamps, electricity costs will be as follows:
Total for 1 day will be 1.8 kW + 0.18 kW ~ 2 kW
In total, 2 kW will be wound in 1 month * 30 days = 60 kW

How much will you have to pay?

Let's take the cost for 1 kilowatt = 4 rubles.
Then for 1 hour of a 60W lamp we will pay 0.06 * 4 r = 24 kopecks.
for 1 hour lamp 95 or 100 W = 0.1 * 4 r = 40 kopecks.

When using 6 light bulbs 3 - 100W 6 hours/day and 3-60W 1 hour 180 watts/day we calculate:
Expenses for 1 day we get 2 kW * 4 r = 8 rubles per day
for 1 month 60 kW * 4 r = 240 rub. in 1 month

Before moving on to calculating the energy consumption of the following types of lamps, you should take into account that with the same lighting power, the power consumption will differ significantly. Therefore, for further calculations we will take light bulbs with the same luminous power as conventional incandescent lamps.

We present a table corresponding to the power consumption of light bulbs with the same luminous flux. That is, each column of the table represents the same glow power. The first line is the power of an energy-saving lamp, the second line is the power of an incandescent lamp with the corresponding luminous flux.

From the 1st column we see that a 6-watt energy-saving lamp shines the same way as a 30-watt incandescent lamp.

The following 2-line plate shows the ratio of LED to incandescent bulbs.

Fluorescent lamps (energy saving)

Then, in order for the house to remain as bright as with conventional light bulbs, you need to install the corresponding light bulbs, that is, instead of 60 watts, we put an energy-saving 12W, instead of a hundred we put an energy-saving 20W, this way we will reduce energy consumption and pay 5 times less.

Thermopot - how much electricity does it consume?

How much electricity do we spend?

So let's calculate how much electricity our fluorescent lamps will consume, for this we take the same example of 6 light bulbs, 3 as hundreds, i.e. 20 W and 3 as 60, i.e. 12 watts.
We get:
3 light bulbs, each for 6 hours a day, each light bulb consumes 20 W per hour, then we get 360 W. + 3 light bulbs for an hour a day at 12 watt/hour = 36W.
Total for 1 day: 360 W + 36 W = 396 W = 0.4 kilowatts
Total for 1 month: 0.4 * 30 = 12 kilowatts

How much will you have to pay?

The total monthly amount payable for pure lighting will be as follows:
Total in rubles for 1 month: 12 kW * 4 r = 48 rub.

As a result, when using energy-saving lamps, instead of 240 rubles per month, we will pay 48 rubles. And if we look at the savings for 1 year, we get instead of 2880 rubles, we will pay 576 rubles.

The benefit is obvious: energy consumption is reduced by 5 times. Is it possible to save even more on electricity consumption by lighting devices?

Let's move on to an even more interesting and economical lighting device.

LED


Lamps of this type are even more economical and consume electricity not 5 times less than conventional light bulbs, but 7 times. That is, if we want to replace 75 watts, then an LED one will be suitable for 10 watts, while the glow will remain the same.

Not long ago the New Year came, and as it usually happens, I thought about New Year's decorations at the last moment. After running around the nearby stores, I realized that it was unlikely to be possible to buy a normal LED garland for reasonable money. We celebrated the New Year with the remnants of our former luxury.
And so, on the January holidays, I went to websites to look for a garland, after half an hour of browsing, BIC was selected, where the specified garland and many other useful small things were ordered. The order was divided into two parcels and sent on January 9. I received both parcels by mail on February 29, March 1, although November would have suited me :).
The total length of the garland is 10 meters; I specially counted the number of LEDs - there are exactly 100 of them. LEDs are transparent, the wire that connects them is transparent and soft. The plug is ordinary, suitable for both Soviet sockets and new “euro” sockets.


LEDs in four colors: red, green, yellow, blue. The garland has 8 operating modes:
1. All LEDs light up, and they all simultaneously change brightness from the “off” state to the “full brightness” state. The maximum power consumption in this mode is 8.0 W.
2. LEDs flash, LEDs of two colors light up at the same time.
3. All LEDs are constantly on. Power consumption 8.0 W.
4. All lamps flash at different frequencies (flowing effect). Power consumption 4.4 W.
5. LEDs of two colors light up at the same time, then one color goes out, and a new one lights up (the “stepping” effect). Power consumption 4.1-4.3 W.
6. One color flows into another. Only one color glows at full brightness at a time. Power consumption 2.2-2.6 W.
7. All programs alternate (“random”).
8. Everyone blinks quickly. Power consumption 2.6-4.1 W.


I understand that reading is one thing, but seeing it is another. Let's watch the video.


P.S. The cat refused to be photographed wearing the garland.
P.S.S. First review, a lot of products arrived, maybe I’ll describe the rest... we’ll see. I'm planning to buy +14 Add to favorites I liked the review +14 +31

New Year's garlands, bright and fashionable! Choosing holiday illumination

What's a Christmas tree without a garland? What's a holiday without twinkling lights? - It's time to decorate the house with Christmas lights. And our tips will help you choose the best New Year's garlands.

How to choose Christmas tree garlands?

When going to buy New Year's illumination, decide in advance: where you will hang the garlands - on the street or in the house, what the length should be, and operating modes. These requirements will vary depending on the technical specifications, permissible voltage and power.

Any New Year's garland, regardless of the manufacturer (Russia, China, Europe), must be accompanied by a certificate confirming the quality of the product and compliance with firefighting GOSTs, as well as instructions in Russian.

New Year's electric garlands: safe and beautiful!

If the garland has a device for controlling music and flashing modes, make sure that the certificate contains a reference to the electromagnetic compatibility protocol. Your new Christmas tree garland should be safe first and foremost.

And, of course, beautiful. Appearance, shape, garland color We select it to suit the style of the festive interior, in accordance with our preferences. The most elegant ones are garlands with figured nozzles and lamps. These are all kinds of stars, snowflakes, bells, little animals and hearts - for every taste.

Street garlands are a holiday for everyone!

Outdoor garlands are produced taking into account operating conditions: they have increased moisture and frost resistance, are tear-resistant and resistant to sunlight.


The cartridge of a New Year's garland for the street must have a special seal that protects against dust and humidity. The outdoor garland packaging is marked IP 23.

Garlands for the street: important!

Choose New Year's garlands for the street with special attention. Outdoor garlands are suitable for decorating indoor spaces, but not vice versa. “Homemade” Christmas tree garlands cannot be used for outdoor decorative lighting - a short circuit is guaranteed.

Electric garlands: safety rules

1. When purchasing, check all the elements of the garland: the connection of the block and wires, the tightness of the insulation, the number of light bulbs, the safety of the sockets and plug. While still in the store, ask the seller to turn on the garland and check that all modes are working properly.

2. The distance from the plug to the last light bulb of the garland must be at least 1.5 m, so that in case of fire there is time to pull the wire out of the socket.

3. Included Christmas garland Spare bulbs should be included. Don't forget to replace them on time. The heating temperature of the garland bulbs should not exceed 65°C.

4. Do not leave New Year's electric garlands unattended. Changes in mains voltage or melted insulation can cause fires. And, of course, an electric garland that is turned on is not a toy for children and pets. Try to hang the garlands in the house at such a height that it is not easy to reach them.

Christmas tree garland power

1. The power consumption of the Christmas tree garland should be no higher than 50-60 W.

2. In the garland between the light bulbs and the plug, there must be an adapter that reduces the voltage in the electrical circuit.

3. The wire of the New Year's garland with flexible durable insulation must have a cross-section of at least 0.5 square meters. mm.

LED garlands: rain, fringe, balls - choose to suit your taste!

LED garlands are a completely different matter. They are extremely fireproof, economical (on average, they consume 5 times less energy than electric ones) and are no less effective. True, the cost will be 2-3 times more expensive.

The service life of LEDs is quite long. The LED garland will last for more than one New Year's holiday, without failures or replacement of elements. If one LED fails, this will not affect the operation of the entire garland.

New Year's LED garlands are very light - to reduce weight, the wires in them are made thin. The LEDs do not heat up during operation.

The only “disadvantage” is that LED garlands require more careful handling. It is advisable not to drop fragile LEDs or subject them to mechanical stress.

The range of LED garlands allows you to create the most incredible holiday backdrop. The decoration of the house will be a rain of light, a waterfall, fringe, shining threads and icicles. LED garlands in the form of multi-colored balls look very elegant. Great for outdoor decoration led curtains- real light fireworks.

LED garlands can be used not only on New Year's Day. This is an excellent option for decorative lighting for your home or office. The section of the Catalog "Electric lighting. Lighting equipment" will help you choose products.

  • The wires of the garland also vary in color. A green Christmas tree has green wires, but what if your Christmas tree has an unusual silver or white outfit? Choose a Christmas tree garland with clear or white wires.
  • How to hang a garland on a Christmas tree? Starting from the crown, from top to bottom, in a circular motion. At the same time, make sure that the cord does not get tangled in the branches, and that the bulbs are directed outward and not towards the trunk of the tree. First we hang the garland, and then the Christmas tree decorations and tinsel.
  • What if the tree rotates? To avoid tangling the cord, choose a Christmas tree spinner with a garland outlet that will rotate with the tree. The LED garland can be powered by a battery and mounted on the trunk.

New Year's garlands on the window

  • LED garlands are well suited for decorating windows, as well as chandeliers and lamps, mirrors or picture frames. Choose the size of the garland for the window according to the perimeter of the frame. Flickering lights will create a magical atmosphere of comfort in your home. Just don’t forget about simple safety rules (see above).

DIY New Year's garland

There is no way to decorate your home with electric or LED garlands? This is a great opportunity to show your imagination - replace them with homemade garlands made from paper, pine branches, ribbons, tinsel and bells, fruits and sweets. After all, the most joyful holidays are ahead!

As always, New Year's holidays are characterized by peak loads in electricity consumption for the population and a decrease in consumption for industrial enterprises. Most of the city's enterprises do not work in the first days of January, during the so-called “New Year holidays.” The holiday maximum consumption is recorded after the start of work of some enterprises after January 4th.

Energy consumption during the New Year holidays – by population

Frosty weather has a great influence on the level of consumption; the widespread use of heating devices contributes to an increase in the load of city residents.

Electricity consumption on holidays for residents consists mainly of preparing the festive table; in this case, one should not forget that energy savings for the New Year can be achieved on holidays and at night by homeowners with a special meter installed with the current two-rate tariff.

Another point that energy workers pay attention to is the operation of the TV, which can be turned on in many families throughout the night.

Urban electricity consumption

One of the most significant objects of electricity consumption on an urban scale is the consumption of electricity by city Christmas trees.

Despite the fact that LED garlands are used everywhere, and they are distinguished by the presence of a wide price range from 800 to 18,000 rubles. depending on the length and configuration, lamp garlands are added to them so that the cost is significantly less although they consume much more energy

The average power of a garland used to decorate, for example, a central city square, reaches 15 kW/hour, while the power range can vary from 5 to 40 kW/hour.

New Year's garlands are hung from December 10 to January 14 and are constantly on from 17:00 pm to 10:00 am the next day.

Calculation of electricity consumption by a city Christmas tree

Formula for calculating consumption of 1 New Year's garland per day

P (consumption) = N avg. power x t.
If N = 15 kW/h
t = 17 hours, then it turns out 15 x 17 = 255 kW

Total electricity consumption P total = P x n
Where P day is the electricity consumption of one garland per day
n – The number of city Christmas trees, individually for each city, can reach an average of 50 pieces. P total. (day) = 255 kW x 50 pcs. = 12750 kW

For 35 days from December 10 to January 14, the total electricity consumption of New Year's Christmas tree garlands is 446,250 kW.

Which represents quite impressive consumption figures, the data is taken from static data for some large cities of regional significance for the New Year holiday for 2013/2014. And if you calculate these indicators on a national scale, you get a fairly significant figure.

Energy saving in the New Year

Significantly reduce electricity consumption, perhaps reducing the switching period, that is, using the garland from 18:00 until 6 evening hours, and set the installation and connection date for the garlands not on December 10, but on December 21. This mode of operation of New Year trees is recommended for adoption for the New Year 2015. This method of working Christmas tree garlands was taken on the basis of a statistical survey of the population of cities: Moscow, St. Petersburg, Yekaterinburg, Omsk, Novosibirsk and some others.

I would especially like to note the work of power engineers: peak loads, frosty weather and increased snowfall do not contribute to a festive mood. All substations have been transferred to a special operating mode, and repair teams are constantly on high alert. The duty is carried out around the clock, and the duty officers are required to respond to all signals of malfunctions as quickly as possible.

Is it possible to imagine the New Year without a garland on the Christmas tree? No you can not. Beautiful flashing lights will give you the feeling of a fairy tale and create a cozy festive atmosphere anywhere. Today we will tell you how to choose them correctly.

Light source

The light source is the fundamental difference by which you should choose a garland. Those decorations that we remember from childhood are based on mini and micro lamps. They are very beautiful and inexpensive, but they do not last long and are extremely energy-consuming.

Now LED or LED garlands are entering the market. They are not much more expensive and have tangible advantages:

  • service life from 20 to 100 thousand hours;
  • durability - LEDs are more difficult to damage;
  • brightness, pleasing to the eye;
  • safety - they hardly heat up;
  • efficiency - consume much less electricity;
  • moisture resistance - you can safely decorate the house or trees outside.

Wire type

Modern garlands have three types of wires: rubber, silicone and PVC.

Rubber and silicone are very durable, moisture-resistant and weather-resistant. Therefore, if you want to decorate your country courtyard, choose them - they will withstand frosts down to minus fifty.

Garlands with PVC wire are perfect for an apartment - in other respects they are in no way inferior to rubber and silicone ones.

Design

We can talk about the design of garlands for hours. Nowadays you can find light bulbs of all colors, sizes and shapes. And, of course, they decorate not only Christmas trees. For example, curtain garlands are produced specifically for windows.

What you should pay attention to

Length

Let's reveal a secret: the garland should be three times the height of your tree. In this case, for every meter of the tree there should be 300 light bulbs or 100 LEDs.

The wire

More precisely, the length of the wire to connect to the network. If you choose a garland for an apartment, focus on 1.5 meters, if for the street - 10 meters.

Wire color

The point is that the wire should not stand out too much from the general background. Choose a garland for Christmas trees with a dark green wire, for trees outside - black, for indoor decoration or Christmas trees of unusual colors - transparent.
