Every year, LEDs are finding wider application, and can be used in many areas of lighting technology, including lighting of housing and communal services and emergency lighting systems. LEDs are indispensable in all kinds of design projects, including the design of architectural structures, decorative lighting of cars and much more.

All this is made possible by their clear light, economy and safety. LED luminaires are installed in porches, underpasses, elevators - wherever minimal maintenance and energy saving are required with proper quality and reliability of lighting equipment.

The power of LEDs increases all the time, their luminous flux increases, and it is not at all surprising that these components are also in SMD design now no less, but in recent years - more and more popular...

Since the development of the first practically applicable LED by the University of Illinois professor Nick Holonyak in 1962, more than half a century has passed, however, the revolutionary invention to this day undergoes progressive changes, becoming more perfect and more technological and useful.

The electroluminescence of a semiconductor transition, with the recombination of electrons and holes, is now the basis for supereconomic light sources. LED, often called LED (short for English light-emitting diode), lamps are gradually gaining a stable position in the market of modern energy-saving lighting technologies, both for domestic needs, and for enterprises and even for street lighting systems. LED lamps outperform compact fluorescent lamps ...

As often happens, everything turned out quite by accident. A friend asked me to deal with the high power consumption of garden lighting in a country house and its reliability. If necessary, I asked to put a separate voltage regulator for lighting, since the mains voltage is unstable and often low.

About a year ago, an acquaintance already began the struggle for energy savings. He replaced incandescent lamps in garden lights with compact fluorescent energy-saving lamps. The energy savings turned out to be significant when compact fluorescent lamps were installed instead of 21 pieces of conventional 60-100 W lamps. The company did not stint and put "OSRAM" 24 watts. The homeowner arranged a saving result. But over time, the disadvantages of the new lamps became noticeable. For example, a base with electronics for an energy-saving lamp ...

In addition to white LED stripsdescribed in a previous article tapes with color LEDs are also available. Currently, it is only 4 colors: red, blue, green and yellow. The LED housings are the same as in the white tapes. Colored ribbons are used mainly for decorative lighting, modding of computer cases and cars, as well as at discos and other entertainment events.

Usually they are called RGB tapes. Each LED of such a tape is an assembly of red, blue and green LEDs. RGB tape has 4 pins. One conclusion is common and three separate conclusions for each color.

According to the laws of physics, from these colors you can get the whole gamut of shades. This is how colors appear on the TV screen. Naturally, to control such a tape you will need ...

LED strips can be seen almost everywhere.A car is driving, and in its headlights the LEDs are brightly lit. Motorists affectionately call such a backlight "cilia." The purpose of such a backlight is daytime running lights, this is a requirement of car inspection, and not the desire of a car owner to decorate his car. Such lights are much more economical and more durable than incandescent lamps used in headlights. However, if you want to decorate your car, you can use the colored ribbon, gluing it wherever your soul desires.

You go to the store, there are also LEDs everywhere: the goods on the windows are highlighted, various cabinets are also indicated by luminous stripes. Even street advertising is highlighted with LED strips. And no one soldered these LEDs one at a time, everything is already soldered to us. In domestic conditions, LED strip can also be used. This is the illumination of ceilings, aquariums, cabinets ...

Regardless of the type of lighting electric lamp, the main characteristic of this product is the type of cap. It is through the base that the lamp is attached to the cartridge and the possibility of its connection to the device depends on its device.

Today, there are a huge variety of socles, so specialists in this field have developed a certain classification and encryption of these devices.

The classic version is the Edison threaded base (indicated by the Latin letter - E). It is widely used to quickly connect many types of lamps used in chandeliers, household fixtures, etc. The number next to the letter E indicates the diameter of the thread. The most common models are E14 and E27.There are also socles for more powerful E40 lamps.The second most popular is the pin cap (G). They also have a large scope. ...

To an uninitiated person, such a question may even seem strange. How could the idea of ​​using 12-volt luminaires and lamps in residential premises be born when the standard for household voltage in our country is 220 volts? Let's try to figure it out.

First of all, 12 volts is an ultra-low voltage, which is considered conditionally safe for human life and health. For this reason, in rooms with a high or increased degree of danger, the use of 12-volt lamps is welcomed by the rules of PUE.

Bathroom, kitchen, outdoor courtyard - these are the places in which low-voltage lighting has always been preferable. And in cramped and damp basements, it is completely impossible to operate a 220 volt network, and it is mandatory to install a step-down transformer even to power portable power consumers. 12 volt wiring does not require ...

Compact fluorescent lamps are increasingly used every year to illuminate both residential and industrial buildings and structures. Initially, the use of so-called housekeepers was due to the saving of consumed electric energy. Indeed, a compact fluorescent lamp consumes 4-5 times less electrical energy compared to a conventional incandescent lamp. But are they saving money?

Many will answer negatively, since the experience of using fluorescent lamps in everyday life indicates that there is no saving in the family budget. In this case, the fact is that the housekeepers fail, and not having fulfilled the term of work declared by the manufacturer, and accordingly its cost does not pay off by the amount of electricity saved. But, in any case, if it is correct to operate compact fluorescent lamps, they will serve the declared term ...
