The light bulb was invented by Edison. Edison was born in Milan, Ohio, USA, and died in West Orange, New Jersey, USA. He was an inventor and entrepreneur. Edison was the first person in human history to use the principles of mass production and the laboratory of electrical engineering research to patent inventions that had a major and far-reaching impact on the world. He invented the phonograph, movie camera, light bulb, etc. He has more than 2,000 inventions and more than 1,000 patents.
It is generally believed that the electric light was invented by American Thomas Edison. In 1801, British chemist Davy electrified platinum wire to produce light. He also invented the electric candle in 1810, which used arc lighting between two carbon rods. In 1854, Henry Goebbels used a carbonized bamboo filament and placed it under a vacuum glass bottle to energize it and emit light. His invention today appears to be the first practical incandescent light bulb. The light bulb he tested at that time could last for 400 hours, but he did not apply for a design patent in time.
In 1850, the Englishman Joseph Wilson Swann began to study electric lights. In 1878, he obtained a British patent for a light bulb powered by carbon filaments under vacuum, and began to establish a company in the United Kingdom to install electric lights in homes. In 1874, two Canadian electrical technicians applied for an electric light patent. They filled the glass bubble with nitrogen and used an electrified carbon rod to emit light. But they did not have enough financial resources to continue developing the invention, so they sold the patent to Edison in 1875.
Edison's biggest discovery was the use of tungsten instead of carbon as filament. Then in 1906, General Electric invented a method of making tungsten filament for electric lights. Eventually a cheap method of manufacturing tungsten filament was solved, and tungsten filament light bulbs are still in use today.
The biggest problem with light bulbs is the sublimation of the filament. Modern incandescent lamps generally have a lifespan of about 1,000 hours.
