Who was the inventor of the electric light?

1in September, 878, Edison began to study electric lights; 1879 65438+1October 2 1, the electric lamp was successfully developed; 1880, the whole world is looking for suitable bamboo, among which the carbon filament made of Japanese bamboo is the most practical, and this kind of lamp is called "carbonized bamboo filament lamp". 188 1 year, at the Paris World Expo, Edison exhibited a 27-ton power generation equipment, which could be illuminated by 1200 electric lights.

Edison has been trying to improve the filament. After several years of repeated experiments, Edison finally invented the high-resistance carbon filament vacuum incandescent lamp in 1879, and established a brand-new atmospheric transmission system.

1880, Edison and his team made a kind of carbonized bamboo filament lamp, which can emit light continuously 1200 hours. Lighting the world's first stable electric lamp with commercial value. Since then, Edison's name has entered thousands of households with electric lights.

Edison discovered the "Edison effect" when studying light bulbs;

1883, Edison observed that a copper wire was sealed in the bulb. He thought that the copper wire could prevent the carbon wire from evaporating and prolong the life of the bulb. After repeated experiments, although the carbon wire evaporated as before, he found that there was a weak current passing through the copper wire after the carbon wire was heated, which was later called the "Edison effect".
