Who is the inventor of the electric light bulb?

Edison.

Edison was born in Milan, Ohio, and died in West Orange, New Jersey, USA. He is an inventor and entrepreneur. Edison was the first person in human history to use a large number of production principles and electrical engineering research laboratories to patent inventions, which had a great and far-reaching impact on the world. Invented the phonograph, movie camera, light bulb, etc. , with more than 2000 inventions and 1000 patents. It is generally believed that the electric light was invented by Thomas Edison, an American. 180 1 year, the British chemist David electrified the platinum wire to glow. 18 10, an electric candle was invented, which was illuminated by an arc between two carbon rods. 1854, Henry Goebbels put a carbonized bamboo filament under a vacuum glass bottle to make it glow. Today, our invention seems to be the first incandescent lamp with practical value. The light bulb tested at that time could last for 400 hours, but the design patent was not applied in time. 1850, the Englishman Joseph Wilson Swan began to study electric lights. 1878, the light bulb powered by carbon wire in vacuum was patented in Britain, and a company was established in Britain to install electric lights in every household. 1874, two Canadian electrical technicians applied for a patent for electric lamps. The glass bulb is filled with nitrogen, and the electrified carbon rod glows. But I didn't have enough financial resources to continue developing this invention, so I sold the patent to Edison at 1875. Dixon's greatest discovery was that tungsten was used as the filament instead of carbon. Later, in 1906, General Electric invented the manufacturing method of tungsten wire for electric lamps. Finally, the method of manufacturing tungsten filament at a low price was solved, and the tungsten filament bulb has been used ever since. The biggest problem of light bulb is the sublimation of filament. The life of modern incandescent lamps is generally about 1000 hours.
