The Life of modern man is unthinkable without the use of electricity. To date, the bulk of the sources of light - electric. About 15% of the total amount of electricity generated is consumed by lighting devices. To reduce power consumption, improve luminous efficiency and increase the life of the light sources, it is necessary to use the most economical light sources, gradually abandoning the older and unnecessarily energy-consuming counterparts.

Light-bulbs

Consider the generally accepted classification. On the basis of the principles of operation of appliances in the lighting plan follows illuminating lamps: incandescent lamps, including halogen lamps and discharge lamps and led, which over the past few years have become increasingly popular.

lighting bulbsIt is Worth noting that the bulbs vary in shape, size, amount of energy consumed and heat transfer, lifetime, cost. So, consider electric lamps lighting more detail and define the advantages and disadvantages of each type.

Types of lamps

Which of the bulbs is the cheapest and easy to use? That's the familiar incandescent lighting veteran in numerous household appliances. The low price and ease of use make them popular for decades. They are not afraid of differences of temperatures, they instantly lit and do not contain hazardous mercury vapor. incandescent lightingProduce lamps of different capacities from 25 to 150 watts. However, the number of hours of work of such lamps is low, only 1000, and the consumption of electricity is much higher than energy-saving counterparts. With time allocated during work vapour glass bulb becomes cloudy and loses its brightness. Because they are unprofitable, and eventually give them up. So, in many European countries their manufacture and sale discontinued and prohibited by law.

Reflector lamps

Found the application and reflector incandescent lamps. In many respects they resemble incandescent bulbs, the only difference – silver plated surface. Use it to create directional lighting to a certain point, for example, in the window or Billboard. Label them R50, R63 and R80, where the number indicates the diameter. They are easy to use, equipped with a screw base of standard size E14 or E27.

Fluorescent lamps

As you know, for the work of lighting is necessary about 15% of all electricity generated. Agree, it's very much. For reduction of this indicator requires the transition to more fuel-efficient light sources. Under current law, in 2014 the power of lighting lamps should not exceed 25 watts. In place of the usual incandescent bulbs with energy-saving fluorescent came, which consume five times less electricity, the lighting level remains the same. What are they? This glass bulb is white, covered on the inner side with phosphor and containing an inert gas with a small amount of mercury vapor. The collision of electrons with mercury vapor provides ultraviolet light, and it, in turn, by the phosphor is converted to light which we are accustomed to seeing. feature lampThe service Life of these lamps about a year, or 10,000 hours of continuous operation. But lamps of this type have one significant drawback: they contain mercury. Therefore, they require very careful use and disposal. Should not be dropped or just throwing them in the bin – as is known, mercury vapor, even in small amounts is very dangerous. Besides, once in the air, they do not dissolve, and crash, poisoning everything around. Thus, the number of mercury vapor from single broken lamp about 50 mg3 with an acceptable level of vapor concentration is 0.01 mg/m3.

Another disadvantage of such lamps: the color of some of them is unpleasant to the eye, their coverage aggressively. There is a solution: when selecting lamps it's important to consider color temperature. It is measured in Kelvin (K). So, a softer, warmer shade lamps marked 2700K – 3000K, this indicator is most optimal for the human eye when working in the premises, as it is closest to natural sunlight.

The Use of fluorescent lighting

Among a huge number of light bulbs there are those whose main task is to work continuously for many hours. They are used in rooms of a certain type: hospitals, supermarkets, warehouses, offices. It is believed that their light is the most close to natural, hence the name: fluorescent lighting.

Lamps produce an elongated glass tube with the contact electrodes on the edges. They have found application in the home. They are used as the main light on the ceiling or mounted on walls as an extra. Very convenient, for example, in the kitchen above the work surface when you need accent lighting or as decorative lighting in the niches, under shelves and pictures, for lighting aquariums or heated indoor plantsin the cold season. They work from the mains and do not require special converters. Such lamps are considered energy saving as compared to incandescent lamp of old design they are virtually no heat, consumes 10 times less energy and the lifetime is about 10000 hours of continuous operation. But there is one caveat: this lighting is typically used indoors at a temperature of 15-25 degrees. At lower temperatures they simply will not work. In addition to white and yellow, these lights can emit other colors: blue, red, green, blue, ultraviolet. The choice of color depends on the purpose and area of application.

Halogen lamp

Today is used more than one type of lamps consuming twice less energy than their predecessors. These lamps belong to the class of energy saving. This is a halogen lamp lighting, widely used in daily life. Thanks to its compact size it is convenient to use in lighting fixtures the type of lamp, wall lamps, ceiling lamps with custom shades, decorative built-in backlight. lamps, lightingTo fill the bulb of such a lamp, a mixture of special gases with vapors of bromine or iodine. When connecting the device to the network the filament (tungsten coil) is heated and gives glow. Unlike conventional light bulbs, here is the tungsten at heating is not deposited on the walls of the flask, and in connection with gas gives a more bright and long lasting illumination, up to 4000 hours. Such lamps emit ultraviolet rays that are very harmful to the eyes. Therefore, high-quality bulbs have a special protective coating. They are very sensitive to voltage drops very quickly and may fail.

Energy Saving lamp

Versatile and energy-efficient light source today are those that use several times less energy, while not reducing power generated by the flow. As, for example, energy saving lamps, designed for residential and office space. They are versatile and can be used in lighting fixtures of different types. contemporary lamps

Characteristic of the lighting lamps of this type: the power consumption is several times lower than incandescent bulbs, last up to 10 times longer, no heat, no flicker, no buzzing, strong enough, and do not contain hazardous components.

Among the shortcomings are the following: slow heating (up to 2 minutes), work at temperatures below 15 degrees. They cannot be used outside in open fixtures.

Primary advantages of LEDs

But one of the most profitable in terms of energy savings are considered led or LED lamps. In English the LED - light emittingdiode - “light emitting diode". The light output of these lamps 60-100 LM/W and average lifetime is 30 000-50 000 hours. Modern lamps of this type are not heated and absolutely safe to use. Well, if you burn one of the bulbs, it will affect the whole mechanism, it will continue to work. led bulbs for home how to choose
Color temperature they are quite diverse – from soft yellow to cool white. The choice of color depends on the use of the room and the preferences of the owner. For example, for office it is better to choose bright white with a mark 6400К to fit a child's room with natural light, not so aggressive, 4200K, well for the bedroom – a little yellowish tint, 2700K.

And another plus: they are devoid of the main disadvantage of fluorescent lamps buzz and flicker, and the eyes in this lighting very comfortable. They work from the mains 220 W with standard E27 base, and E14.

The Use of LEDs in everyday life

Interestingly, even ten years ago there was no such thing as led light bulbs for home. How to choose and install them, could tell is that the mechanic – after all, they were used mainly on the dashboard of a car and light indicators. Today, the exploitation of them at home has become so familiar that we do not even think about choosing between LED lamps and the lamps of the old model, so the choice is obvious and not in favor of the latter. Highlights: in led lamps the current – a constant, so the cost of heating is minimal. Consequently, they are not heated and as fluorescent lighting, can serve for many years. Despite their high cost, they are beneficial to use. Consuming less energy, these lights help to reduce the monthly amount you pay for electricity. By the way, choosing led light bulbs for home, you should consider the difference in power. There is one secret. Need to know the power which is consumed by the lighting lamp, General purpose, and divide it into 8. For example, if you change the ordinary lamp 100 W, 100 : 8 = 12,5. So, the right led lamp power of 12 watts. led lighting bulbs

Another no less important index – such lamps have a different light temperature. From this indicator depends on how comfortable lighting will provide led lighting lamp in the room. Fromavailable shades of light white is the best shade in the range 2600-3200 K and 3700-4200 K. This light the softest, most close to natural sunlight and pleasing to the eye. The figure of 6000 K gives a very cool white tint, and less than 2600 K - oppressive yellow. These shades are harmful to the eyes, one quickly gets tired, you may have headaches and impaired vision. Therefore, it is important to purchase only high quality led bulbs for home. How to choose to tell the consultant at the store and provide all the necessary quality certificates.

Anyway, while the led lamp is advantageous in many respects.

- It consumes several times less electricity.

- In the process is not heated, which gives the opportunity to use it with flammable material, e.g. curtain rods, false ceiling. A large number of such lamps do not overheat the air in the room.

- These lamps do not burn out, and eventually just lose its brightness to about 30%.

- Long life, up to 15 years.

So, having an idea about what types of bulbs are, knowing their main characteristics, strengths and weaknesses, you can safely go to the nearest store. But there is another important point, without which even a simple replacement of the bulb will be impossible. After all, to pick up a lamp to lighting device, it is necessary to know what kind of its cap. Using the cap lamp is attached to the cartridge, and it delivers electrical current to the bulb.

Select the Right base

For making use of base metal or ceramics. And placed inside the contacts that transmit electrical current in the working elements of the device. Each lighting fixture features one or more cartridges for mounting lamps. It is important that the purchased cap lamp were consistent with the cartridge. Otherwise it will not work.

Despite the variety of types of the bases of the bulbs in everyday life often use two types: screw and pin.

Screw base is also called screw. The title accurately conveys the way the coupling of the cartridge of the lighting device. It is screwed into the lighting of the lamp, on its surface applied carving. For marking use the letter E. This type is used in many types of lamps in household appliances. These bases differ in size. So, marking a base, after the Latin letter E manufacturer must indicate the diameter of the threaded connection. At home we often use bases in two sizes – E14 and E27. But there are more powerful lamps, e.g., for street lighting. They use socket E40. The size of the threaded connections has remained unchanged for many decades. Even now, you can easily replace a blown a light bulb in an old fixture to a more efficient led. The size of the cap and cartridge they are exactly the same. But in America and Canada have different options. Since the voltage is 110V from them, avoid the use of light bulbs European standard diameter of the cap is different: E12, E17, E26 and E39.

Another type of bases used in everyday life, it pin. To the cartridge it is attached with two metal pins. They serve as contacts that transmit electricity to a lightbulb. The pins are different in diameter and distance between them. For marking use the letter G, followed by a numerical symbol of the gap between the pins. It bases G4, G9 and G13.

Now you can safely proceed to repair. And let remodeling or build new walls under force only to professionals, but with the selection and replacement of light bulbs you may well cope on their own.
