💡 What filament LED bulbs: what feature of the new items

Filament LED bulbs are replacing traditional LED devices. Externally, they are somewhat similar to a light bulb, "Ilyich" and have a similar name - light "Tomic". Such devices are more suitable for crystal chandeliers or outdoor fixturesAnd on the efficiency of filament LED is much better than normal incandescent lamps.

What is a filament lamp: an overview

filament LED lamp It is a device in the conventional glass body with the cap, but instead of filaments within the filament set of LEDs with different light color (there are red and blue). Vial completely transparent, as can be seen within a certain number of luminous elements (4 to 6 pieces). According to the established threads can be determined bulb power: 1 thread = 1W.

How does the filament lamp

Bulbs with LED strings bulbs are gradually gaining ground in the electrical market. It deserves thoughtful structure of the device. Light consists of four main parts:

• a metallic cap;
• of thin glass bulb;
• LED strands;
• built-in driver.

Let's look at the details of each part of the instrument and clarify their main function.

1. metal cap appearance standard, but inside there is insufficient space for the full implementation of the board with a capacitor and an inverter. Subsequently developers plan to increase the space inside the cap by mounting between the base plastic edging bulb and socket.
2. glass bulb is no different from the one that is installed on a usual incandescent lamp. Glass is still fragile and short-lived, but the solution to this problem is planned in the near future.
3. LED thread are rod coated with a phosphor, which provides a barrier to penetration UV and stabilizes the lighting, comfortable to view. Inside the protective layer is set at a large number of small LEDs, and their corresponding color temperature of the warm or neutral hue.
4. board with driver It takes up almost the entire space inside the cavity of the basement, but it was enough to bring all the momentum and power for the filament rods. In future it is planned to install a driver volumetric charge, as well as complement the smoothing device capacitor.

Good to know! Cheap Chinese filament lamps do not have a built-in fuse, as fluorescent lamps, so it is better to abandon such purchases in favor of the big-name brands that including eating and in Russia.

A method of heat removal

Work LED yarns carried out by a current, which is below the maximum allowable. In operation, the LED element has a property to warm to 60 degrees, and it fairly high rate, which can cause overheating. To prevent this, the device is provided injection of helium, which takes heat dissipating it. It is known that helium has good thermal conductivity.

However, in the cap cavity there is another heat source - a driver, which lacks the radiator, thereby to slow heat dissipation. As it turned out, a strong overheating of the working board is a long flickering light bulbs and early failure of the device.

Be sure to note the presence of a current driver when buying filamentLED, usually this information is indicated on the packaging.

The angle of the LEDs glow filament

Demand for filament lamps has grown significantly in recent years, and this is due to the integrated approach to coverage in the room. Why user selects this source of light? The fact that the angle of the light emitting devices in the data corresponds to 300 ° C, while the standard LED elements contribute to scattering of rays only at 170 ° C.

This lighting effect is achieved by the correct number of bars bulbs, as well as their equally spaced around the perimeter of the bulb and its perfect transparency. There bulbs in which rods are placed figurno: S-shaped, circular, crosswise or at an angle. This approach helps make the lighting more even. Usually light bulbs with similar properties to acquire fixtures installed on desktopsAs well as for children's coverage.

The main parameters of filament LED bulbs

All information regarding the selected filamentLED can be found on the packaging of the device, but not every farmer is able to correctly decipher what they say. A lot of these combinations can be found on the device and the appearance.

1. Let's start with the standard form of the flask, which is on the box is designated as A60. Also on sale there are spherical or spherical options with the symbol A95.
2. The number of watts, for instance 6 W - is power, which is assigned to this light source. If you have purchased a model with 6 watts indicator, then it will fit 60 W incandescent lamp-term.
3. The number of the Latin letter "E", for example, E27 says that in light bulb provides a standard size cap with a diameter of 27 mm. There are lamps with a reduced base type E14, but these are more suitable for small table lamps.
4. Indicator color temperature may vary. In some models, the glow is 2700 Kelvin, which is accompanied by a yellow light, while the model with a white light heating corresponds to 4000 Kelvin.

Despite the fact that the filament lamps - is an innovative development in the field of electrical engineering, in which there are still unimproved chastnitsy, some of them are subject to immediate processing. This is what experts say improves safety while using the device.

Advantages and disadvantages of filament bulbs

A large amount of products with LED bars can be found in the market, but to identify a cheap fake or real professional thing can be difficult. Therefore it is better to choose the model more or less known by the brand. In fact for this case will not rise as high-quality products has a mass of useful qualities.

Which can be determined from the shortcomings:

FilamentLED - it's light sources, which provide a constant change structure as well as the introduction of new active elements. It is likely that the massive replacement will begin in a couple of years conventional LEDs on the filament lamp.
