Current LED lampa bulbs usually referred to the lighting systems of new generation. Despite the fact that LEDs lampor are invented and used extensively in electronics for many years, LED lamps on the basis of their widely used only recently. At first light-emitting diodes are used only as a signal light bulbs in various electronic devices, and then began to produce industry and household LED bulbs, based on these electronic components.
The LED lampa is essentially a conventional diode with classical devices such pn junction. When passing through a transition of the electric current is the so-called recombination charge carriers - electrons and holes. Scientists have noticed that this process is often accompanied by the emission of light energy. It is this principle lies at the heart of the LED lampor, which are made of LED lights for different purposes. The LED is a point light source, since it has a microscopic crystal. The emission spectrum, which have LED bulbs, has a distinct color. This allows you to combine in one case different LEDs, LED lamps produce any spectrum, from cool to warmer yellow tint. Currently, LED lampor are available with a classic cap-type E14 and E27, which can be used instead of conventional incandescent bulbs, and with caps and MR11 MR16. The latter allows to install similar LED bulbs instead of halogen, common in our days.
Reasons why LED lamps are becoming every year more and more popular, a lot. Indeed, in many respects they are far superior performance as incandescent bulbs, as well as more modern HID lampy.
First, any LED bulbs virtually last forever, their lifespan is over 10 years, now is a record. Explain such a long life may be the fact that the emission is nonthermal nature of LEDs. They have no sensitivity to mechanical stress and quality of electric energy of the filament. By the way, vibration and mechanical strength make LED lamps so common in the automotive industry. Already almost all new cars instead of HID install LED lampor.
Secondly, LED lamps have a low power consumption. If you add the long term service life, we can see that the installation of such lamps is economically justified.
Thirdly, the principle of LED radiation in a different spectrum lamps can make based on them in different colors.
Fourth, these lamps based on LEDs are highly resistant to various atmospheric influences, including those for temperature changes.
Spheres of human activities, which are used LED lampor, a lot. In the first place, is called the illuminated signs in the form of signs, billboards and light boxes. These lamps are used for street lighting and traffic signals traffic signs, as well as all kinds of information boards. In addition, LED lampor are used in the automotive industry in the implementation of indoor and outdoor lighting. The ability to transmit various shades of bright colors make these lamps a favorite tool for designers to implement certain ideas, and resistance to low temperatures allowed the use of LED lampor for decorative lighting of buildings and structures.
