Edison. On October 21, 1879, an American inventor finally lit the world's first practical electric light through a long period of trial and error. Since then, the name of this inventor, like the electric light he invented, has entered thousands of households.
He is Edison, who was praised as the "King of Invention" by later generations.
-
Electric light was invented by Edison. He went through more than 1,000 experiments, and finally used tungsten wire to experiment to be the most durable.
-
Edison only invented the carbon filament electric light and can be used as the pioneer of the electric light. But he didn't invent the tungsten lamp.

[Invented by Edison].
Thomas Edison (1847-1931) was a world-famous American electrician, scientist and inventor known as the "World King of Invention". In addition to his inventions and contributions to the phonograph, electric light, telegraph, and film, he also had many famous creations and insights in the fields of mining, construction, and chemical industry. Edison and his employees made about 2,000 inventions in his lifetime, making great contributions to human civilization and progress.
Edison was also a great entrepreneur, in 1879, Edison founded the "Edison Electric Lighting Company", in 1880, incandescent lamps were put on the market, and in 1890, Edison had already organized its various businesses into the Edison General Electric Company. In 1891, Edison's thin filament, high-vacuum incandescent bulb was patented. In 1892, Tom Houston & Co. merged with Edison Electric & Lighting Company to form the General Electric Company, beginning a century-long dominance of General Electric in the field of electrical appliances.
At the same time, Edison is known as the "father of light", "the real Prometheus" and "the king of invention", and he has more than 2,000 invention patents such as incandescent lamps, gramophones, carbon granules and movie projectors.

The electric light was invented by Humphrey Davy, an Englishman. Electric lamps first appeared in the early 19th century, Humphrey David used 2000 batteries and two charcoal rods to make arc lamps, but this kind of arc lamps are too bright, produce too much heat, and are not durable, and they cannot be used in ordinary places. In 1854, Henri Goebel, a German watchmaker who immigrated to the United States, used one. More.

The light bulb was invented by Henri Goebbels in 1854, using a carbonized bamboo wire, placed under a vacuum glass bottle to emit light and maintained for 400 hours, unfortunately, he did not apply for a patent in time; In 1880, Thomas Alvar Edison of the United States made a bamboo silk lamp that could be lit for 1,200 hours continuously.
-
The earliest practical electric lamp was the incandescent lamp, but long before the birth of the incandescent lamp, the Englishman Humphrey David used 2000 batteries and two carbon rods to make the arc lamp, but the arc lamp was too bright, produced too much heat and was not durable, and it could not be used in ordinary places.

Thomas Edison (1847-1931) was a famous American inventor. He worked almost ten hours a day for decades, and read 3 to 5 hours in the study at night. So, on the day of Edison's 79th birthday, he proudly said to people, I am already 135 years old. >>>More
In 1892, the Russian Slavyanov successfully researched the practical scheme of the current metal arc welding method. In particular, in 1904 the Swede Oscar Kjellberg built the world's first electrode factory, the OK electrode factory of ESAB. During the same period, a large number of studies have been carried out on the coating effect of welding rods in Europe and the United States; In 1910, Sweden invented mineral-type thick coating electrodes, in 1919, the United States invented paper wrapped on the welding core, and proposed the initial type of cellulose electrodes, and in 1921, the British proposed to use marble and fluorite to manufacture welding rod coatings. >>>More
