Wat to ampere converter. Wat to ampere converter

In the rest of the hour, a lot of people are wondering about the transition to the victoria of the bright ones. Previously, there was only one such parameter, like tension, now there is a complete electronic lighting fixture with a decal of the main blocks of life on microcircuits, light from warm to cold, and navit tricolor RGB.

Spivvіdnoshenya to the unknown light-one lamps And the heating lamps are littered with unscrupulous salespeople, for example, suggesting a brightness of 800 lumens and declaring that it is an analogue of the 100 W standard heating.

Table of symptoms of tension

In the table, the intensity of tension for the led with the help of the diodes is indicated, so without a bulb, which reduces the brightness by 15-20%.

The best pardon, if you care, is a 10 W light that is equivalent to a 100 W heating lamp. But for the fact that the matte flask changes brightness by 20% and 1W when it comes to heating the driver, then we are allowed to go out only 7 brown watts, which will give 700-800 lumens in the middle. What is known is not up to the required 1300 lm.

Matte colby stock

On the dimmed diode bulbs there is a vicorous flask for the eyes of others, especially children, who are blinded like a zvaryuvannya.

An analogue of heating at 100W will be two LED lamps with 650 lumens. When choosing, now you don’t varto orient yourself to Wat, but instead select the number of Lumens for the table of viability. The greater the brightness of the diode, the greater the maє buti її radiator. This is one of the indirect ways to determine the tension and choose the correct equivalent.

1. Also on sale you can find out the current G13 light, which can replace mercury in fluorescent lamps by choosing a flow case.

2. Even if your lighting for the premises has not yet been designed and installed, then with a cheaper cost of lighting, you can install it. The panel is 60 x 60 cm and 1 cm thick. Without a living block. Їy can be mounted practically on a lay-up way. Natomisti mi otrimuemo majestic brightness at 3600 Lm for 1250 rubles.

3. I see that some lamps look like corn, the stench may be a good design and do not require a good radiator for the introduction of heat and flasks. The only small one is the electrical contacts of the diodes with a low voltage.

Table of performance of energy-saving

Energy-saving as much as possible effective in post-work, with frequent switching on and vimicant stench, it helps to grow more times, and the back is turned on by half the tension.

Soft characteristics

We choose two words in the store, as if we were guilty of vicoristing “in tandem”, for example, right and the socket, and raptly sticking with the problem - “electrical parameters” on the marking of the indications in different units.

How do you pick up the right ones one to one, attach that outbuilding? Yak amperi translate from wati?

Sumezhni, ale different

It must be said at once that it is not possible to translate a single piece of bread directly, the shards of stench mean different sizes.

Watt - to tell about the exhaustion, tobto. speed, with which energy is saved.

An ampere is a unit of strength, which is to say about the speed of the passage of the struma through a specific cut.

So that the electrical systems were operated without noise, it is possible to decompose the amps and watts for the power voltage in the electrical circuit. Remain - switch to volts and may be:

• fixed;
• fast;
• change.

With an eye on the price, the screenings are carried out.

"Fixing" translation

Knowing that, apart from the values ​​of tension and force, which is the indicator of tension, it is possible to translate the ampere from the vaty using the following formula:

At tsiomu P is the tension in watts, I is the power of the struma in amperes, U is the voltage in volts.

Online calculator

In order to be constantly “in the know”, you can create for yourself an “amp-watt” table with the parameters that are most often measured (1A, 6A, 9A, etc.).

Such a "spіvvіdnoshen's schedule" will be reliable for a measure with a fixed and steady voltage.

"Change nuances"

For rozrahunku at changing voltage before the formula, one more value is included - the coefficient of tension (KM). Now she looks like this:

I’ll transfer the process to one of the world’s smartest and simplest ones, to help such an accessible zasib, like the online calculator “ampere at cotton”. Do not forget that it is necessary to enter a number in the column for a fractional number, to fight through a dot, and not through someone.

In this order, for the power supply “1 watt - how many amperes?”, For the help of a calculator, you can give an estimate - 0.0045. Ale wine will only be valid for a standard voltage of 220v.

Vykoristovuyuchi presented in the Internet calculators and tables, you can not suffer over the formulas, but easily match the different ones in the world.

Help me, please automatic vimikachi on a different occasion and do not worry about your own fittings and electrical wiring.

Ampere - watt table:

As I was so worthy of experimenting with light-emitting lights and reworking the lamps, if I were asked to select goods for testing, then I didn’t hesitate and tried to try the light driver of factory preparation.
Who cares, the development of tsієї ideї pіd katom.

As I have given an understanding in the annotation, the driver of the letter is without cost, however, I don’t have any special significance in this case, so that meta be-any kind of look around - show that the product has come out of itself є і varto yogo kupuvati chi nі. I promise, but I’m not ahead of the curve and show who and who, I’ll look around the 20 watt driver, I haven’t learned here yet.

From the same preamble, having long become a reminder that lamps with fluorescent lamps, broken down by the principle - what is cheaper - more quickly, may have a characteristic defect, with frequent switching on, the stench will not live for a long time, like lamps, like electronic ballasts themselves.
At home, there are a couple of lamps with branded ballasts, Vossloh Schwabe and Philips, the stench is practical, but the price for them is dependent on them, not seeming about those that Yakіsnі Phillipsi has come up with for sale. And although for the main lighting I am still afraid of blocking the light, then for another row I allow it. One of these options will be described in a glance.

Ale, I will be last.
When the driver arrived, it was good speed, about three o’clock, I can’t say for sure, that I had a vin without a track. The package was packed with a standard yellow envelope with a puffy puff in the middle, the driver itself was lying next to the bag with a clasp. Let's look at the monolithic design of the driver, it's foldable. Zagalom nothing especially cіkavogo, packaging yak packaging.

The length of the input cable and the output wires is the same, 27 cm, the outputs are wired at silicone insulation, narrower than soft (de buy such a wire okremo).
Expand the body 75x30x20mm, dozhina with fixing legs - 90mm.

On the back side of the driver, flooding with a mass similar to epoxy resin, which does not allow for the repair of wines. And Skoda, it would be bulo to try to get such a driver yourself or do it yourself. Ale hotіv itself IP65. Zagal їzhte scho zamovali and do not croak. :)

The characteristics of the driver are declared by the compiler.

Basic driver parameters.
Number of light sources 6-9.
The output voltage of the driver is 28-40 Volts.
Strum 600mA.
The seller has specified 20-35V 600mAh 20W LED Driver (10 series 2 parallel)
Trochs do not converge. That minimum of 6 light diodes will give a maximum of 24 Volts, here it is not similar to the virobnik’s data, but experiments will show who is right.

The maximum that I could recognize from the one in the middle, that is, that the capacity of the output capacitor is 100 microfarads, and that is imovirno.
Before the speech, the driver turns on with a delay of about 0.5-0.7 seconds, three times.

Dali I rozpochav viprobuvannya (itself was tsіkavo).
At idle, the driver gives close to 44 Volts

On the back of the head, I navantage a 100-watt matrix (10x10 circuit), the voltage dropped to 30.9 Volts, the strum was 0.57 Amperes, and the voltage was 17.6 watts.

After that, I went over to try out these ideas, with which I planned to win.
Svіtlodiody 10 Watt (3x3 scheme)

2 LEDs in sequence, voltage 19.04, stream 0.58 A, intensity 11 watts.

3 LEDs in sequence, voltage 28.11, strum 0.57 A, intensity 16 watts.

Well, let's try the test that I planned before the new switch, 4 light diodes 10 watts in succession, the voltage rose to 37.08 V, the strum fell to 0.53 A, the intensity increased to 19.65 watts.

In fact, the maximum of the driver. I vvazhu, scho dosit badly.
The need for a little more is spared, ale tim cіkavіshe.

Before the speech, cicavo, that light is three times different, three of them clearly see the crystals at the robot, and the fourth one (in the photo on the right upper one) is as beaten, in the photo it is less commemorated, why so, unreasonably, ymovirno іnsha party.

For gourmets

Oscillograms of the voltage and struma.

Voltage pulsation with a frequency of 100 Hz, 3 light diodes, a scale of 0.2 Volts.

Pulsating voltage with a frequency of 100 Hz, 4 LEDs, scale 0.2 Volts

Pulsation struma with a frequency of 100 Hz, 3 light diodes, a scale of 0.1 Volts, vibrating on a resistor of 1 ohm.

RF voltage ripple, frequency close to 57 kHz, 3 LEDs, 0.2 Volt scale.

For this, the experimental part is over and the time has come to move on to the practical.
How should you understand, the driver, what to lie on the police, don’t bring cory, hіba yakshchos pіdpiraє:)
In one glance, I reworked the lamp of Chinese vibes. In this case, the situation is even similar, so is a lamp, also of Chinese manufacture, and not less extensions, lower in front. And so the very "illness" to the problem of inappropriate work.

Description of the reworking of the lamp.

I wrote on the cob that there are good branded electronic ballasts for linear fluorescent lamps. Є stink є, but for example, stink is not corny to fit into such a lamp. If I've turned the old ballast onto my own driver on the IR2520D, then I'll stick it in that space.
Hope for dovgu work the lamps of the wines were not true, it was more the fault of the part of the vmikannya, like in the first fall, that it was borne out that the readings of the lower lamp under the light were redeemed. Chantly vin vіdomy rich, vibrate their moustache, who is not molting.

Vzagalі hotіv spochatku perobiti pіd light one line, like in the previous situation, but instead of experimenting with light-emitting diodes. By the way, with the method of improving safety, I chose the driver option in a flooded case, navit at the time of the exit from the fret of the wines without burning me anything (and for improving the fact that the bed is made of plastic, then safety is critical).
Light 10 watts is used in a very lightened mode, 5 watts for folding. I'm on the line for a number of reasons.
KKD and the superiority of light in such a regime are commemorative.
Svіtlodiodi I have boules.
Just wanted to experiment. :)

So, as the light needs to be cooled, and the body of the lamp was made from metal for three pieces of foil, then there is a radiator in the folds.
Looking at the new troch of fearfulness, it is clear that having been lying down to finish the wine for a long time, it is possible to twist those stars, it is possible to buy for someone else, but to go farther away.

Chantly, a lot of radioamators, but not only, remember the standard open transistors of the type KT808, 805 or analogous (ex nostalgia, self-confidence from the Radio magazine, then Radiotekhnika UKU 020, for a long time it was cebulo).
Ale, well, it was my inspiration, if after the reconciliation of light-emitting diodes I found out that such a transistor is ideally equipped with a 10-watt light-emitting diode, moreover, with the first addition, it is possible to turn the transistor into a winner. So, as radiators and such transistors, at one time it was broken even richer, then, perhaps, this information will be correct.

Ale to all your time.
Radiator buv vіdmitiy i razpilyany navpіl, along the way, vіdrіzav elementi fastening zі vіrnogo side, sensu in them is not, only zavazhayut.

This is how the lamp looked after the dismantling of the whole thing.
The space for the installation of radiators and drivers is close to 490x75mm (the metal part of the lamp).

At the radiators, open the drilled crepes for light, and the radiator is fixed to the lamp, cut M3. For the sake of interest, I attached 2 light-colored screws, as if thinking about a light-colored plate, and other 2 light-colored washers like the old KT808, like thinking about Radianskiy engineer. Before the speech, for 10 watts of light, it should be installed between 19mm crepe openings (they make a square with 19mm sides), if anyone needs it, I didn’t get the information on the Internet, but I did it experimentally. Fastening with washers like transistors was better, no drilling, drawing thin.
Zvichayno KPT-8, where would it be without it.

Having mounted the radiator and the driver, for the grounding clamp, it was necessary to find a place for the M4 cuts on the radiator, right down to the speech. The driver did not become nailed, gluing it on a double-sided tape, marveling, as if it would fall, I would nail it. Light to the radiators and radiators to the body are screwed with screws with a pressure washer, such screws are equipped with computer cases, even by hand.

After driving the light driver, the driver was not turned on before the trial.

Yakscho honestly, I will not say what was worthy. All right.

Poganyav about s pіvgodini. Vimiryav temperature. I think the attachment is a breeze, it’s closer to 50 on the dotik. It’s easy, through a bad thermal contact (I want the sensor to be squeezed through the paste), in the photo the sensor is inserted into a large hole for the lower transistor in the radiator.

The driver heated up to 60 degrees, guessing, pratsyuє wines at its maximum intensity.

I can say in a flash that it shines brightly, darker lower than the front 2x18 Watt luminescent lamp and light is normal, looking approximately like a halogen. The heating itself is normal, but the sound was not worthy.
The plastic of the rose is too far-fetched, it’s uncomfortable to go out, if the lamp is spent in the field of dawn, I think that for additional places (my lamp is installed in the comor) it’s a lot of attention, in other situations I’d better rebuff the light one of the lines (in such a way).
Ale retinues with the donka, a new lamp was worthy, for me those are the best. :)
I want to try to add a matte finish, it’s like a weed.
Having tasted the first rose matt, I don’t take alcohol, but in the case of acetone wine, it starts to sag even with small cracks. If anyone knows the ways, please suggest.

Summary
The driver is completely normal, the strum of a trohi of underestimation as declared by the virobnik, 550-580mA against 600 declarations by the virobnik.
Having heated up at the maximum intensity, which is actually quite normal in the normal mode, the vibrator declares a maximum of 75 degrees, in my closed building it was close to 60, marveling at how practical it is.
The pulsations are small, the “olive” test must be passed, or you can add more credit at the exit, more for everything else to change.
Not a lot of voltage included from the zatrimkoy, but it’s already individually.

Kupuvati chi ni, varto wine of your pennies chi ni, virishuvati you, looking around, I tried to show my real characteristics as much as possible, I am convinced that I had it.
Never forget anything. Especially such a team, who could read to the end.

The driver is free of charge for testing and I will look around at the Chinabuye store.
