The history of the development of electric lighting takesIt began in 1870, when the incandescent lamp was invented, which produced light using electric current. The history of the development of electric current began much earlier, when the experiments of the famous scientist Volta ended with the creation of an alkaline battery. And the very first devices for lighting, which worked on electric current, were created at the beginning of the XIX century. They tried to use them to illuminate the streets, but they were too expensive and inconvenient.
The revolution was made by an engineer from Russia PavelYablochkov, who opened the “electric candle” on December 12, 1876, which, with the help of electricity, became a convenient source for lighting. An important revision in the created Apple incandescent lamp was invented by the famous American Thomas Edison. He placed the device in a vacuum shell, which protected the contacts with the electric arc from oxidation, so his lamp could give light for a sufficiently long time. With it, the history of the development of electric lighting has received a powerful impetus. On October 21, 1879, he turned on the first light bulb, which was able to burn for two days.
With a light hand of Thomas Edison electricThe light bulb became a commercial product and became widespread at the beginning of the 20th century. In the future, the history of the development of electric lighting has already begun to move forward thanks to the vigorous activity of scientists and inventors, as each new invention symbolized a new stage in the development of the lighting industry.
In 1901, Cooper-Hewitt demonstrated a low-pressure mercury lamp.
In 1905, the first lighting lamp with a tungsten filament was made in Auer's workshop.
In 1906, the scientist Kuh invented the high-pressure mercury lamp.
In 1910, an important key breakthrough was made in the discovery of the halogen cycle.
In 1913, the inventor Langier demonstrated to the public a gas-filled lamp, which later received his name.
In 1931, the scientist Pirani manufactured a low-pressure sodium lamp.
In 1946, Mr. Schulz hit everyone with a xenon lamp.
In 1958, halogen incandescent bulbs were born.
In 1962, the first LED with a red emission spectrum was created.
In 1982, the world saw low-voltage halogen lamps.
In 1983, compact fluorescent lamps were invented.
In these dates, the history of the development of electricallighting is shown not only in the form of advanced achievements of science, but also in the form of inventions embodied in final consumer products. In modern times, serial production of a wide variety of electric light sources, including LEDs, which have received final recognition in history, is already well established. Their advantages are the enormous service life, high luminous intensity, tiny dimensions and the almost inexhaustible potential of energy saving. However, while the extensive use of LEDs can only boast the history of the development of electronics.
LED technology in electric lightingin the near future must finally win their rightful place. The future is seen in the competition for dominance between LED and luminescent light sources. The luminescent lamp, which today is the most demanded source of light, owes its position to the respected Soviet scientist S.Vavilov, who gave a powerful impetus to the development of such lighting and created the foundation of lighting engineering. It was under his leadership that the phosphor was developed, which transformed the ultraviolet radiation spectrum into a spectrum that is clearly visible to the human eye. A good future also awaits a xenon lamp.
