LED revolution: what is the advantage of LED lamps over incandescent lamps?

 

LED revolution: what is the advantage of LED lamps over incandescent lamps?Reason for switching to energy-saving LED products. Comparison and simple mathematical calculation of the savings and benefits of the purchase in the long run.

Today, many talk about new energy-saving technologies. What's coming soon traditional “Ilyich’s bulbs” live out their Age and a new era is coming, or rather the electrical LED revolution.

This issue has risen to the state level. Starting with the President, who gave instructions to the state corporations Rosstekhnologii and Rusnano, to introduce energy-saving technologies, due to the fact that electricity is not used up efficiently and it is time to break stereotypes and keep up with the times. Factories will be built in a short time on the territory of Russia, where they will produce LED products and laboratories for their manufacture already exist, although they are very few and the cost is still high compared to LEDs from Asian countries.

What do modern technologies and the State in the person of these technologies offer us? What are the features led bulbs? And what are their advantages over ordinary incandescent lamps? Let’s try to look at it with our own eyes, without particularly going into politics and the production process, but look at the finished product through the eyes of consumers.

I will say right away that these products have been on the Russian market for several years. And this gave a wide response only when we all have echoes of the financial crisis. That the cost of energy is rising and often unreasonable. The state has finally paid attention to modern news. Although people who follow new technologies are always the first to start using them, taking advantage immediately, not expecting a drop in prices during the competition for customers, by this time, these people are already paying back their expenses. Yes, at an early stage this will seem like an expensive pleasure, but there are advantages and note that there are practically no disadvantages. But soon, you will understand and see, there are much more pluses and everything is accompanied by absolute benefit.

So, let's begin! We outline and compare our favorite incandescent bulbs and LED bulbs.

incandescent lampIncandescent bulbs consume their designation plus five or seven percent loss. It turns out that a lamp that consumes 75 watts actually consumes 78 watts, or maybe more. In addition, only 95% of electricity is converted into heat and only 5% into light, this is a very small figure, moreover, this heat increases the risk of fire. A gradual evaporation of the tungsten wire quickly puts the bulb out of action, it also beats easily, and inside it is harmful substances. What can I say about new lamps that do not have flickering, but only uniform light, there are no harmful substances, and yet, they are very durable and practically do not heat up.

Let's compare a 75W bulb with an analog of an LED lamp? What correspondence will be analogous, you think? I am sure you will be pleasantly surprised, only 10 watts. Almost 7.5 times less consumption, illumination is better, as well as efficiency. Also, lamps 40W = 5W and 15W = 120W, respectively, LED analogues.

The service life of an ordinary lamp is 1 year, but the LED is 5 years, but with a small caveat, if using it 10-12 hours a day, you can extend its service life to 12 years.

If these arguments are few, then I will show that I have in store for you. A complete mathematical and economic calculation that will complement your picture of the new generation of lamps and the fact that they will quickly pay for themselves.

LED lampWe take a period of 5 years, as much as a minimum, one LED light bulb will cost an average of 500 rubles - this is 10W.For the same period, we will need 50 incandescent lamps 75W at 8.5 rubles each and for 50 lamps it is 425 rubles. That is, one LED lamp will replace 50 ordinary ones. For the price and not such a big difference, you say: 500 and 425 rubles. (prices can vary, as well as the cost per 1 kW of electricity, but the calculation model is fair, you can calculate at different prices depending on the region, I took more or less relevant prices at the time of writing).

It seems like it is not convincing? We go further, we calculate the energy consumption, which the incandescent lamp and LED lamp will use for 5 years.

So, are you ready? 3750 kW, our ordinary light bulb eats so much and only 500 kW LED. Now we multiply these figures by the cost of 1 kW, my figure, at the moment it is 2.43 rubles. per kW, you have it, I repeat, it can change.

And what did we get? For 5 years, the energy consumption of an ordinary lamp is 9113-00 rubles. and only 1215-00 rubles. LED light.

We add the cost of buying lamps, plus the total cost of energy consumption, for the same 5 years.

The traditional lamp is 9538-00 rubles. and 1715-00 rubles. at the LED.

Now, it remains only to calculate how much savings we get when replacing one LED lamp?

And that is the figure ... are you ready? This figure is equal: 7823-00 rubles.

This treasured difference is 7.5 times, even with a slight plus, savings on purchases and energy costs.

Now you understand the value of contributing to the long term, that here you get only positive points. In any case, you decide, but do not forget that you will have to move over time to a new technological level. Indeed, a ban is introduced on incandescent lamps and thereby, they will gradually be withdrawn from circulation. This is one of the programs of the State policy in the field of electrotechnical prospects.

I hope that you have received comprehensive information and this article will inspire confidence in your choice or at least give a detailed picture of future prospects.

    my incandescent bulbs last for years while such junk in almost all respects as housekeepers fly - like seeds! not far from them and led. And incandescent lamps have no particular problems with energy consumption - it’s better to pay attention to how much electricity the trinket absolutely unnecessary in the apartment eats like a computer!

    Do you have an incandescent lamp life of 1 year in Belarus? At my place in Russia, Philips lamps last 2–3 years. And these are passage rooms (corridor, toilet, bathroom). So your calculations are no longer true. This is the first significant minus. In stores in my city, LED lamps (similar to 75W) cost 1000 rubles, not 500 like yours. This is the second significant inaccuracy. And the third and most important, in my opinion, is the emitted spectrum of LED lamps. Why did you “forget” to indicate that it has a striped spectrum, which affects vision very badly? Now let's think about which lamps are better for our health? ..

    "The service life of a conventional lamp is 1 year ...; We take a period of 5 years ...; we need 50 75W incandescent lamps at 8.5 rubles each ..... "

    Oh how !!! With an order of magnitude errors, further calculations do not make sense.

    In a modern 3-room apartment there are from 10 to 15 lamps (including chandeliers). According to the author, for five years should I change 50 - 75 lamps? Is the cap completely gone? Now I have only 3 incandescent lamps: 120-150 watts each, installed: balcony, corridor, in one room. They are already several years old. Low-power lamps 25-40 watts in general can not be considered as lamps, shit else. But the housekeeper is a burnt bag. Most of them burned over 15 watts, with spirals.Records - 1 month in the kitchen worked. 9W lamps - only one burned out in 3-4 years. And what is not heard and not visible induction lamps?

    This is not the case for most people. Moreover, light bulbs with a power of 100 watts and more are no longer produced and not sold. 10 - 15 incandescent lamps for an apartment - this is the most common (rooms and kitchen have 3-5 lamps, an entrance, a toilet, a bathroom). In reality, 50-75 lamps burn out in 5 years, we just don’t count them, otherwise, if we counted, we would be very surprised. I now have a lamp with halogen lamps in my nursery (I hung it after repair in April). During this time, 3 bulbs had to be replaced and this is only for half a year. Compact fluorescent lamps of normal manufacturers work for a long time, but they cost more. The lamp that you burned out in 1 month, even if it is of an unknown manufacturer, can be replaced under warranty (minimum warranty is 6-7 months).

    Seen for sale in one store. Only the seller said. that they are not much better than luminescent. Is it true or just the seller advertised fluorescent?

    the author compares the power consumption, but at the same time forgets about the luminous flux, which the diode lamp is several times less. luminous flux is measured in units of lumens (Lm). in order to get a luminous flux like a conventional lamp you will have to use about 2 to 6 LED lamps (depending on the number of diodes and their model)

    and so from personal experience:

    an incandescent lamp with a rating of 65w - base type E27 - consumes about 67-70w - gives about 800 lumens - life time of about 2 years.

    fluorescent lamp (analogue 65w) - cap type E27 - consumes 13w - gives about 610 lumens - service life 0.5 - 6 years (as luck would have it, it was burned out right away, but there are some since 2004)

    LED lamp (3pcs = analog 65w) - E27 socle type - 3w one pc (44 diodes, diode model 3528SMD) - gives about 260 lumens - service life from 1 to unknown (because they burn out one diode each).

    ps: the lamp life depends on the number of on / off. and power surges. in order to prolong their life, it is necessary to install voltage filters or ignition units.

    Yes, the calculations are not true. My personal implementation is this:
    - I live in a three-room apartment - 11 lamps, in living rooms and a hallway 8 incandescent lamps for 8 fluorescent lamps (only one burned out during the year). thus I used to pay 1200r for electricity. per month in winter and 750 in summer, and now 750 in winter and 550 in summer.
    Conclusion: in the winter I save 450 rubles a month and in the summer - 200 rubles. during the year approximately 325 p. It turns out 3900 rubles a year. I spent 1100 rubles on 8 fluorescent lamps. (price for purchased from 120 to 140 rubles).
    Incandescent bulbs used to have to change quite often 5 replacements with 8 bulbs per year (these were simple bulbs from 75 to 100 watts; their price was from 8 to 12 rubles). Now there are 3 incandescent lamps in the house, of which two are made by Philips and one ordinary has been working for several years (Philips cost 70 rudders).
    I thought of replacing them with diode ones because my eyes hurt from luminescent ones. And the savings are noticeable.

    For all CFLs, the spectrum is inferior, in the living rooms I left the halogens, although they eat 400-500 watts per room. Vision is more expensive, you know, my wife works at home at the computer, and from CFL her eyes hurt. And she earns a computer so much that halogens do not put a sin.
    But in the kitchen, the hallway CFL are appropriate, especially since they burn all evening and morning, for a total of 5-6 hours a day.

    See the article as custom-made or advertising, the author himself never used LED lamps, it is not possible to look at them, etc. energy-saving lamps, too, a slop miracle burn faster than ordinary incandescent lamps. I would like to see 100-watt bulbs back, but for now I put in 60-75 watt bulbs for 2-3 - the most pleasant light with them.

    An LED lamp equivalent to 100W costs ~ $ 50-60, taking into account delivery and a wrapping of 1.5. 

    This is with more or less branded LEDs. (they are made at the factory, and they have a name and specifications). Try to find documentation on the LEDs installed in the lamp you purchased.

    But you can’t sell a light bulb to anyone for that kind of money. Everyone wants cheaper. Naturally, the Chinese ordered lamps with "expensive" LEDs and the "right" power for them. And of course, for some reason, these lamps shine in the wrong spectrum, and do not live long. And instead of an aluminum heat sink for the crystal is plastic. In general, it looks like an expensive lamp only cheaper. And what are we, fools, to pay a lot of money for light bulbs, when there are the same, only cheaper.  It is such a bulb with a tenfold wrap that fits into your usual price range.

    It is clear that calculations are a marketing ploy. And it’s also clear that there is a saving. The only question is that these new products do not live for five years. And the question of the health benefits of the emitted spectrum is not covered. Who says this when it comes to saving)
