How to choose an LED lamp for your home
Soon, LED lamps will be breaking news, and the assortment of them in the store is limited to a few models. The day is more sensible than choosing a source for semiconductors on a bright light, turning into truly problems. What is the design and characteristics of the LED lamp? How are they by principle and how are they different from each other? Dnes we will decide these questions.

Koi LED mugs sa good
For yes, dissuade me from this question, it is necessary to clearly and clearly understand how the LED sources for lighting are and how the technical characteristics are, which are important. We see someone, no matter how the proposal is to modernize the farm, and yes, let's solve some problems.
Power and light stream
Somehow every other crush, LED is characterized by energy consumption, some of which are measured in watts. Kolkoto is more than a consumer device, more sensible, naturally, it shines strongly. The brightness of an ordinary se narycha is a bright stream, some of it is measured in the lumen. Obviously power and light flow are interconnected. For example, an 8-10 W LED fan generates a flux of about 700 lumens. A lot or a little e for such power?
Can't you dissuade the Vednag, cash? In an extreme estimate, LED from the bright spot appeared relatively hastily and did not mix with the tyah, somehow, let's say, from the top of the litter box.With tyah everything is simple: almost every si imagining sharply brightly shines sixty cotton wool. For yes, we will evaluate the Energiynata Enepaeratialist (to the condemnation for generating Svetlinen, the flow of km consumation on Energy) on the LED outright on Svetlin, a kind of characterization of the mu with good cognition of the junk and in the time of the time of the time with a little cognitive lamp "(LDS ).
Energy Efficiency Compliance Table for push-button, low-energy LED and fluorescent lamps

The table clearly shows how the energy efficiency or, somehow, the light efficiency on a semiconductor source at a bright line is 8-9 five temples from the energy efficiency on a helix coil and two five temples from a fluorescent tube. For yes, there is a bright stream from 700 lumens, one plug on Ilich and consumer 60 W electricity, but LED light is needed from no more than 9-10 W.
According to Tozi, start semiconductor switches san nai -economy environments and existing sources in the light.
color temperature
Probably the stems have become whiter, because the light from the lamp with the burner and the fluorescent tube is different. Unity e-topl, zheltenikav, echo e-student, ss signo, “sick”. This property of a light source is characterized by a parameter for color temperature, which is usually measured in Kelvin. Look at the picture along the length:
Dependence on the visual perception of light from neinat color temperature
It was clear to show that the temperature is brightly colored, sensible in the student's light. In general, there are 3 main gradations for temperature: fuel, neutral, cold. A lamp with a lit litter, somehow veche razbrahme, a light source of fuel. What is the type of LED light fixture? Showing off, no matter what. Everything depended on the goods, as well as the materials used to crawl for it, the production was not ready. Go to your nearest store and take a look at the packaging for any LED mug:
LED lights with different color temperatures
Answer by answering the inscriptions, Ima lamp Studena Svetlina, on Wednesday it is neutral and the fire is bright in the air. What a mess, what was the rule of this light e "fuel"? Do you see the 3000K sign? Tova is nothing more than a color temperature, calculated in Kelvin. Spore predishnat figure 3000 Ke fuel light.
The next question is: what is the color temperature of the lamp and if there is one LED lamp for the house? All the more depends on your preference. But have a foresight that the payment of a bright vacation, a student’s dokato sebir and concentrator. In terms of tosi, it’s starting to be kind and restful on fires of light, but work on neutral or cold light.
Index on color rendering and coefficient on wave
It is very sensible that indicators for all sources for light are important, as indexes for color rendering and coefficients for pulsation. How is it?
Color rendering index
Probably they turned white, it’s common and eating for daytime light and lamps from the lit lamp, the evening is turned on, and the appearance is completely different. In the evening, you bloom in a rich way, heat up the color in a bright way, the atmosphere is warmed up.Tova, lie on the fact that in the daytime light, you see bloom on the object takiva, like a vito sa. And a krushkata with a hot bug, for the sake of your own spectral characteristics, distorting the color rendering: some colors look bright, others pale, they communicate the contrast for me.
The ability to use lighting power and produce true color scoring index on the color rendering index, which is denoted with CRI (color rendering index) or Ra and is measured as a percentage. Kolkoto in a high e, sensible in exact sa bloom. The light-line source has an emission spectrum index of 100, but it is extremely difficult and unjustified to use an artificial source with such a CRI.
Depending on the quality, color temperature and design on the LED, the technical index on the color rendering range is from 80-90 and can reach 95. There are many good indicators for LED lamps, but other types of devices can be praised. Be sure to hit with a trigger, for example, CRI, depending on the power, it can vary between 60-80 and not more.
How do you flower depending on CRI per source per lightline
Factor on ripple
Probably they were whitewashed, what a trabnata LDS, especially as an old one, pulsira is white. Tova strongly moryava ochite and ima negative effect vrhu psychikat. Light from the litter box with a pulsirate, but pulsate them with no sense for the sake of inertia on the spiral from the litter box. Silat on the tesi is measured and senaricha is the coefficient on the profit in percent. Kolkoto in a low way, it’s smart, little by little, get rid of the light from such a source. Tova e especially verno, kogato illuminate the working places and zones for rest.
What is the ratio of ripple to LED from source to light? Much depends on the manufacturer and the quality of the lamp. Pulsation coefficient for high quality lamps usually does not overhang 5-10%. The budget option can be 15% or 25%. As far as falsification is concerned, the law is not written for theses: maybe 30% and 80%. How can homeowners consider it acceptable to use LED lamps in an apartment?
According to the sanitary rules and despread SaNPiN 2.21 / 2.1.1.1278-03 lamps with a pulsation coefficient of 15% can and can be mounted on all sorts of homemade items, including lighting for work places and places for even.

LED covers are offered in various shapes and with some basic types. It is possible to use LED analyses, in standard lighting bodies from different types. Nye is popular, parsing it, it is based on Edison E27 and E14 (minion). These LED lamps are ideally suited for lighting the body, which are designed and work with conventional lamps from a pressurized liquid. For example, for yes, replace the top with an Ilic with an E27 base with LED, it’s enough just to develop the right one and to curl the second one on it’s own. For projectors of the industry, I produce LED covers from the base G4, GU5.3, GU10. Those are the ideal substituents on a halogen lamp from a light source. Ima and a substitute on a classic fluorescent tube are a standard LED lamp with a G13 base. Externally, all the tezi tsokli look like this:

Dimmable
They probably waited and maybe they crawled out the pre-switch for the dimer, instead of the key, which somehow twisted more smoke or a little bit of a bud.Smoked smoked, pressed buds - and zadadoh desired lightening in flocks.
Turning the dimer, instead of the standard pre-switch
Vsichko tova work wonderfully from the knuckle with a jarring jug. But is it possible to adjust the brightness of the LED lamp first? Possibly e, but the very same samata krushka e is intended for tov. On the other hand, think about how we dim. How can we distinguish a dimmable bulb from an ordinary LED, which brightness can not be adjusted?
Once you wrap the LED light bar, take a close look at the packaging. Ako ima inscription kato "dimmable", "dimmable" or something similar, togawa lampata is dimmable. Instead of an inscription, it is still possible to have an icon, which is sometimes zapakovkite with dimmable lamps, and is shown on the figure along the bottom.
All tezi cups are dimmable
Once you understand the distance of the LED lamp, you can dim it, read a lot carefully and label the packaging. A lot of manufacturers will tell you succinctly why the lampata can’t be dimmed: “it can’t be dimmed.” How much you read nabarzo, skips "not", then buy it is absolutely sinful!
Design for lampata, krushkata and glala on izlchvane
In addition to the light flux, the characteristic of the LED source for light is important, which depends on the design of the lamp. Samiyat LED is radiant at a angle of 100-130 degrees. Ako semi-conductors from the location in one and the same plain, togava lampata still shine under the eyes, probably a little on the heads of the gl. But dori and when crawling on a special scatter light cap and reflectors, tozi ygl did not overhang 160, about 180 degrees.
LED covers with 110 and 160 degrees angle
Ty kato vvv any lamp sa installa dozens of LEDs, gylt on the device on the device, it can be forested and changed through the supply on the semiconductor for different angles. Takiva designs sa in the state and cover the sector up to 300-330 degrees (stopalata is often covered from mazeto).
330 degree LED mugs
Why is it necessary to choose a lamp, why should I foresee it for cover? In the first place, they illuminate various areas. The unity illuminates a little, echoing the floods of the tsyalat flock of light. According to the beginning, the lampata with a narrow angle is ideal for spotlights and devices for local lighting, but it is absolutely not suitable for using, in other words, in classically poured and vice versa.
Ima still one nuance. Experience and visually compare the brightness on the lamp, which creates a bright stream, but the image is different in coverage. Closely shine two to three five in a bright way from the round lamp. Why?
Thy kato in parvata the lamp of the lumeni vishki sa concentrates in a relatively small platen ygl, dokato the second lamp distributing the vishki of the lumeni clearly and clearly in the literal sense. That is, a lampata with a cramped gll ima is flattened by a light stream, which means something that it’s brighter.
Tezi lampi produce a bright stream, but the lampata otlyavay im two five-fold density. back kjm sdzharzhanieto ↑
Evaluation on the quality of the model
The last important criterion for the selection is quality. Which LED lamps will you choose for your home? Vsichko here depends not only on your budget. The principle of “sharply in a smart way, sensible in a good way” work only partially. Don’t try and pick up a lot of skypi devices from well-known manufacturers: the most expensive price is dictated by markat.That is to say, the cloak is not sensible for the lampat, stings for the fact that "NIE go right!".
But the company is unknown or little known, but it’s alarming, especially if it’s a product and a single cost.
Prove the producers, koito yama and wi hvarlyat bokluk, sbrakh in chinya. Nadiavam, yes, help me with the choice of an LED mug.
