The invention of incandescent lamps begins with the advent of electricity in the 18th century, which prompted many scientists to engage in their own experiments in the field of electronic technology:

In 1800, a galvanic cell was created, serving as a current source, called a "Voltaic column".
In 1809, a light bulb with a platinum spiral was created by Gerard Delarue.
In 1854, Heinrich Goebel invented a lamp similar to a vacuum vessel with a bamboo thread inside. For 5 years, Goebel was developing his lamp, but he could not patent it because he was an emigrant without money. But he found a use for his invention in lighting his own watch store.
Another Russian inventor was P. N. Yablochkov, who invented an "electric candle" with a long service life. Its development began in Russia, and then in Paris. In 1876, an exhibition was held in London, where Yablochkov showed his invention. After that, his lamps began to meet in Paris, and then all over the world.

In the 1880s, Thomas Edison and another talented British scientist, Joseph Wilson Swan, created the famous Edison and Swan company, later known as General Electric. In his incandescent lamp, he used a platinum filament and immediately patented his invention. But this type of lamp was not widely used due to the fact that the product was very expensive. Thomas returns to the idea of ​​a carbon rod lamp and a year later creates a lamp that lasts for 40 hours. And it was Edison who managed to develop the base and cartridge.
