Brief history of the development of electric lighting

The history of the development of electric lighting dates back to 1870, when an incandescent lamp was invented, which gave light by means of an electric current. The history of the development of electric current began much earlier, when the experiments of the famous scientist Volta resulted in the creation of an alkaline battery. And the very first lighting devices, which worked on an electric current, were created in the beginning of the XIX century. They tried to use them to illuminate the streets, but they were too expensive and uncomfortable.

The coup was made by an engineer from Russia Pavel Yablochkov, who on December 12, 1876 opened an "electric candle", which with the help of electricity became a convenient source for lighting. The famous American Thomas Edison invented an important modification in the Yablochkov incandescent lamp created . He placed the device in a vacuum envelope, which protected the contacts with the electric arc from oxidation, so his lamp could give light for a fairly long time. With its help, the history of the development of electric lighting received a new powerful impetus. On October 21, 1879, he switched on the first light bulb, which was able to burn for two days.

With the light hand of Thomas Edison, the electric light bulb became a commercial product and was widely used at the beginning of the 20th century. In the future, the history of the development of electric lighting has already started to move forward due to the stormy activity of scientists and inventors, since each new invention symbolized a new round of development of the lighting industry.

In 1901, Cooper-Hewitt demonstrated a low-pressure mercury lamp.

In 1905, the first lamp with a tungsten spiral was made in Auer's workshop.

In 1906, a scientist Kuhh invented a mercury lamp of high pressure.

In 1910 an important key breakthrough was made on the discovery of the halogen cycle.

In 1913, inventor Langier demonstrated to the public a gas-filled lamp, which later received his name.

In 1931, a scientist Pirani made a sodium lamp of low pressure.

In 1946, Mr. Schultz strikes everyone with a xenon lamp.

In 1958, halogen incandescent lamps 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 electric lighting is shown not only in the form of advanced achievements of science, but also in the form of inventions embodied in the final products of mass consumption. In modern times, the serial production of a wide variety of electric light sources, including light-emitting diodes, which have been finally recognized in history, has already been well established. Their advantages are a huge service life, high luminous intensity, tiny dimensions and an almost inexhaustible energy-saving potential. However, while the wide use of LEDs can boast only the history of the development of electronics.

LED technology in electrical lighting in the near future should finally win its worthy place. The future is seen in competition for the dominance between LED and fluorescent light sources. The fluorescent lamp, which today is the most popular light source, owes its position to the respected Soviet scientist SI Vavilov, who gave a powerful impetus to the development of such coverage and created the foundation of lighting engineering. It was under his leadership that a phosphor was developed that transformed the ultraviolet spectrum of radiation into a spectrum that is clearly visible to the human eye. A good future also awaits a xenon lamp.
