How are dimmable LED lights and how are they different from conventional lights?
LED crush sa good for vitchki: the consummation is small, they shine brightly, they serve for a long time. Maybe the only problem is smoothly adjusting the brightness to such a light source - they don’t work with dimers. But these problems can be solved if you use dimmable LED lamps for lighting, which work perfectly with conventional dimming. It is for these lamps that we say dens.

Brightness adjustment for LED lights
They probably waited and maybe they crawled out a dimer - a pre-switcher, which ima twisted with a smoke or a little bit of a bud instead of a key. Toy zavrtya smoked, presses the bud and set the desired lightening in a flock or, it is scientifically shown, exchange the stoicity for a light stream.

These devices work perfectly with the lamps from the plug-in, but if you replace the crankshaft with Ilic with LED, you will have a problem. The illuminator of the moment, shingle, arbitrarily changing the brightness or dori is generally not included. But it's not so strange: it's hard to adjust the LED covers and pay special attention to the technical design. In the extreme mark of the spiral with the injected liquid and the semiconductor diode is completely different.
What e dimer
Dimert, somehow veche doseshatate, its device, which allows you to smoothly and change power, is given a lot of goods. Dimer, some work vvrzka with electrically plugs and exchange intensity for light, often se narich dimer. Devices can and have different principles for working, but all of them are fresh to a single point: they are effectively straining the goods. AC dimmers, namely those who are of interest to us, use the principle of cutting off partly from half a wave. Kolkoto in a golyama is often sloppy, little sensible tension from the back of the goods - krushkat.

Characteristics to work on a dimmable LED lamp and eliminate the differences from conventional
There is a problem with the brightness regulation on an ordinary LED lamp. What are the chances? In fact, a semiconductor device, such as an LED, therefore constantly stores voltage during operation and is variable in the lighting environment. Osvent tova current, replacing the pres of the diode, tryabva yes, it is strictly defined. Otherwise, damage the device.
A dimer, embedded in an LED cap or a lighting rod, is correct. That converts the variable current voltage into a constant voltage and lowers it to the required value. Additionally, setting the necessary current for the pres diode and supporting it on the given field is stabilizing.
How are these cases, how can you experience this and obscure a single crucible for tosi beginnings? Zavartate smoky and effective tension in the goods for me. But the driver for a 220V LED lamp has clear instructions - yes, maintaining voltage and current for a given field. Toy varshi work, dokato mozhe. Zavartash - nothing for me.But if the input voltage is really low, the device will fail: if the diode is switched off (Markov products) or the ground is unforeseen (budget option). This is just an ordinary LED lamp, switched on through a dimer.
Designer solve the problem with dimming on the LED lamp, by changing the verigata to the driver. Now watch that one carefully, attached to the kum krushkat. If you open the window, you will automatically change the current of the LED. A little voltage means a little current. A higher voltage means a higher current, but the very same is not the maximum allowable. As a result, it is possible to adjust the brightness on the product, but the protection on the diode preparation is safer. Such a modification of the illuminating body byah called dimmable lamps.
Such LED headlights, in which the dimming mode is foreseen in the design, can even be used with a dimer. But with koi? Change the current dimery, who work on the principle of half a wave, there are two types.
- Razryazvane on the front rb.
- Cut on the rear rb.
What is the meaning of tova? Prviyat type attaching itself the remainder of the semi-final for exchanging the current of the goods, the otryazvayki is often used for the goods. Vtoriyat gave half a wave from the very beginning, but the rest is broken at exactly the same time. Looking like this:
Razryazvane on the front rbb (leaky) and rear rbb on the half-way
First of all, spread it for the sake of simplicity on the schematic and a lower price. The last one is a little squeaky, but a little embarrassment, which they can reproach for working on an audio equipment.How can dimming models work and dimming caps? Both from the tezi and from the other side, but they repeat the option (preferring to the rear ribs) is preferable, so that the pressure on the illuminator is increased gradually, and not sharply. Tosi mode e to - “disassemble” for drivers on dimmable plugs.
Ako veche imate installed avant-garden dimer, but decide yes go change mugs diode, then feel free to change it. Always work better, provided that the LED caps are adjustable and of high quality.
How can we distinguish a shady crown from a conventional one?
Produce daylight lamps with the possibility of dimiran not all distinguishing visually from ordinary. All the differences, somehow sort it out, sa v'tre, verigata on the driver for protection. For yes, you can figure out how the type of device is kept in the system, try carefully and study the packaging or friendly documentation, as well as takava. On the packaging on the mug with the possibility of dimirane trebva and ima, the inscription "dimmable", "dimmable" or something similar is answered. Often, instead of the inscription, they use icons depicting turning the regulator on the dimer.

Adjustable LED body lights
Let's leave some crashes for a known time and let's talk about LED lamps, which are not a little popular. How do you get the blackouts as possible and adjust the brightness with tyah? Ima a lot more options from LED taillights. Depending on the task set, you can choose one from the following:
- Illumination shaft with vgraden dimmable driver.
- Illumination body with extensions dimmable driver (usually spotlights).
- A lamp with a dimer, embedded in the driver - you don’t need to dory, but you need to separate the dimer separately.
- We dim the driver behind the LED body illuminator.

Advantages and disadvantages
The benefits of dimming LED lamps are pre-conventionally obvious: they have the ability to provide optimal lightening of the area by simply turning on the smoke or pushing on the bud. Osventa’s brightness on the illuminator can be changed smoothly, and not in stages, such as, for example, in multi-stage polyleys, sometimes two self-made ramen, and four times a lot.
Another obvious preference for a dimmable LED lamp is that when changing the brightness, the color temperature remains low, which is not possible, for example, conventionally use a lamp with a light switch. From the paint to the brightness, the lightness of the light becomes yellow to them, muffled.
But lamp with a dimirane there is a lack of:
- The lamp, which may or may not be regulated, is a little more stringy from the obyknovenat si colleague. It's small, but it's there.
- Crush on some manufacturers do not work well with dimers for separate companies. In this case, there is no quality on the dimer itself, nothing can be seen on the regulator and may have a meaning. Usually, this is all attributed to the budgetary lighting of the body and all sorts of falsifications.
- The extra time for setting is usually 10-25%, about 5% of the brightness value. For a LED lamp with a high power, 10% is bright enough, and 25% is defined as a lot.
Somehow you can see, Ima is lacking enough, but if you wish, you can tear yourself away from it, as follows:
- Buy dimmable lamps from well-known manufacturers - Osram, Philips, Gauss, etc. Technite products, as a rule, work with AC dimers.
- Go ahead and buy it, say yes and tell the lamp to be dimmed, so don’t work for you.Almost all the sellers, with the exception of the izmamnitsy, se crossed in half for tosi questions.
- Do not buy lamps on unknown brands such as Pxilips, suspiciously evtiny and even more often from a tray in the market.
- Try and choose a device with a lower price at a regulation rate of 5% (for a quality product, the characteristics of the ripple are even higher than the packaging). Ako take 10%, togawa self-needed capacity, no margin. Do not take 25% of the total - dory at minimum brightness, the lamp still shines very strongly.
How do we choose
What are the criteria for choosing a dimmable lamp? Let's choose a basic one:
- Power... If you decide to replace the lamp with a dimmable LED light, then have a foresee how you can get a bright stream, LED consumer light 8-10 five times a little less energy from a lamp with a light switch. That is, a semiconductor illuminator with a power of 6-7 W will also give an extra amount of light in a 60-watt Ilyich plug.
- Sokl… Dimmable LED Covers are offered in different sizes on the Edison base and shield. You will assure yourself that you need a device exactly with such a basis, for yes, not a tax, but a hundred thousand.
- Dimmable... Before you buy a device, intend on packaging the designation for dimming the lamp (pisah for tov in a mountain). Ako kupuvate is ordinary, take it back, osven ako, sort it out, do not burn out the trace of the first turn on the president. Probability from a rise to a similar situation e golyama.
- Shape and size… Pay attention to the format, appearance and size to the device. In a disgusting case, you might not fit into the plafond on the polyley or ruin the external view of the lampat.
- Manufacturer… Buy cups with dimirane samo from brand name.Some technical devices are a little better than the Chinese ones, but they will definitely cost the whole thing for a warranty period and give a good sensible light, which is announced by the manufacturer.
In conclusion, briefly for the product at the manufacturer, for some reason, and pay attention, sometimes you buy LED caps.
Osram
A well-known German company specialized in the production of lighting equipment. Osram produces LED covers, including dimmable ones, with different colors and temperatures and bases E14, E27 (Edison base) and G9, G12, GX53. Take two products that are produced in a classic form for a firebox or a lamp and serve as excellent substitutes for a burner in the opening of the body illuminator.

Philips
The company is not little known from Osram. Using innovative technology, the company has achieved an exceptionally high operational life on dimmable lamps (up to 40,000 hours without significant loss in brightness) with energy efficiency class A ++ (Master MV Value, LEDclassic). In addition to the classic lamps, Philips can also come up with original solutions - truly Edison lamps, self-dimmable LED. Värno e, MTBF technologia e "self" 15,000 hours (capped with a pressable stopper for 1000 hours).

gaus
Characteristics of the LED caps on the basin of the company is a wide range of voltage protection: from 185 to 265 V. This product is very important for areas with poor quality protection. Satisfied with technology, the index on color rendering, which has reached 90. Not all companies produce lamps with intelligent high performance.
Interesting is the series of Gauss Step lamps with a step-like obscuration.For tyah, a dimer is not needed, a verigata for a change in brightness is even embedded in the lamp itself.

Uniel
The medium is produced by the manufacturer Uniel, which is of particular interest to dimmable lamps from the Cristal Dimmable and Palazzo Dimmable series. The devices are distinguished by good color rendering (up to 80) and glare in relation to shading: they work perfectly with a naked variety from AC dimers, working on the principle of semi-completely connected. Lampe with the possibility of dimirane and from two series of imat matirana mug, shape, base on a conventional mug with a pressable button and work instead of tyah without any problems.
Other products include lamps with E14, E27, GU10, GU5.3 fasungs, as well as original HV format devices on the cover for Ilic. The company has its own production capacity in Russia.
