Today we can not imagine life without the light of electric lamps, each house has lights, chandeliers and nightlights. Someone buys the lamp wholesale, but someone on one, but ended up anywhere there is an electric light – and in a private comfortable home, and on huge enterprise. The History of the lamps lasted for several decades, at various times were very different opening, which bring the lamp to a modern, all the familiar sight. Back in 1809 an Englishman Delara building the first incandescent light bulb with a platinum coil, and then in 1838 a Belgian invents coal lamp. A Heinrich Goebel invented the first valve, suitable for use as early as 1854. July 11, 1874 Russian engineer Lodygin receives a patent for 1619 on a filament lamp.
As the filament he used a carbon rod. Baby clothes‘s opinions are widely known. Alexander N. Lodygin was a native of the Tambov province, and although, as mentioned in the history of the lamp is not the single name of the inventor, namely Lodygin suggested the use of the lamps the tungsten filament in a spiral shape, which are still used in modern lamps. Also Lodygin first guess is pumped from tubes air, so their lifespan is increased by several times. Another invention is designed to increase lamp life, was filling the lamp with inert gas. School Furniture has similar goals. In 1906, Ladygin sells his patent to General Electric, but because of the high value of tungsten is only limited use of the patent.
Probably the most famous name in the history of the lamp is the name of Thomas Edison, who in his research work tries as a thread Filament various metals, in 1879 he patents a lamp with a platinum filament, but then returns to the carbon fiber. However, the Edison invented the chuck socket and switch. It was his invention displaces gas lighting. An interesting fact is that until the invention of Edison did not become popular, people slept for 10 hours a day. The last date in the creation of the lamp is 1910, when William David Coolidge invented an improved method production of tungsten filaments. Today bulb replaced with modern energy saving lamps, which are no longer spend much energy on heating the air around him. The popularity of these lamps because of their economical to use and long life. Unlike classic lamps life 1000-1500 hours, they can serve and 8000. But these lamps, unfortunately, can be harmful, since their uv emission, and people with Sensitive skin should not forget to be careful while using them. Inventor of energy-saving lamp is Ed Hammer. Their work is based on the motion of electrons under high voltage, advantage of this lamp is the fact that his eyes almost never tire under the influence of such light. Whichever the lamp does not light your home, the usual "light Ilyich" or modern lamp with energy saving lamps, we have never can not without them. Lamps have become part of our everyday lives, and their creation is the work of many people who wanted to make the world a little brighter and have done so.
