history of electric lighting dates back to 1870, when it was invented by an incandescent lamp that gave light by means of electric current.The history of the electric current began much earlier, when the famous scientist Volta experiments resulted in the creation of an alkaline battery.And the very first devices for lighting, which worked on the electric current, were created at the beginning of the XIX century.They tried to use the street lighting, but they were too expensive and inconvenient.
coup committed engineer from Russia Pavel apple, which is December 12, 1876 opened the "electric candle", which with the help of electricity has become a convenient source for lighting.An important revision to the established Yablochkov incandescent bulb invented by Thomas Edison, the famous American.He placed the device in a vacuum shell which protect the contacts with an electric arc from oxidation, so it could give the lamp light long enough.With it, the history of development of electric lighting has received a new impetus.October 21, 1879 it included the first light bulb, which was able to burn two days.
With a light hand of Thomas Edison's light bulb has become a commercial product and is widely used at the beginning of the XX century.In the future history of the development of electric light already began to move forward with a flurry of activity of scientists and inventors, as each new invention symbolized a new stage of development of the lighting industry.
In 1901, Cooper-Hewitt demonstrated the low-pressure mercury lamp.
In 1905 the workshop was made Auer first lighting the lamp with a tungsten coil.
In 1906 Kuh scientist has invented a high pressure mercury lamp.
In 1910 he was made an important breakthrough on the key opening halogen cycle.
In 1913, the inventor of Lang makes a public gas-filled tube, which later received his name.
in 1931 Pirani scientist has made a low-pressure sodium lamps.
In 1946, Mr. Schultz hits all xenon lamp.
In 1958 came to light halogen bulb.
In 1962 he created the first red LED emission spectrum.
In 1982, the world saw the low-voltage halogen lamps.
in 1983 were invented CFLs.
In these dates the history of the development of electric light is shown not only in the form of advanced science, but also in the form of the invention, as embodied in the final products of mass consumption.The current time is well established for the mass production of various electric light sources, including LEDs, which have received a final acceptance history.Their advantages are a great life, high intensity, tiny size and almost unlimited potential for energy savings.However, while extensive use of LEDs can boast only the history of electronics.
LED technology in the electric light in the near future should finally win its rightful place.The future is seen in competition for dominance between the LED and fluorescent light sources.Fluorescent lamp, which is now the most popular light source, owes his position to such distinguished Soviet scientist Vavilov, who gave a powerful impetus to the development of the lighting and lighting created the foundation of science.It was under his leadership was developed phosphor, which transformed the ultraviolet emission spectrum in the range, clearly visible to the human eye.Also expects a good future and a xenon lamp.
