In what year did Edison light the first lamp in the world with electricity, and since then, electricity has illuminated people's lives?

1879101October 2 1, the electric lamp was successfully developed. Edison tried nearly 1600 materials for this purpose, and the filament of this electric lamp was burned after 45 hours of continuous use. This is the first electric lamp with wide practical value. This kind of electric lamp includes "high resistance incandescent lamp" and "carbonized cotton filament lamp".

From 65438 to 0880, Edison sent assistants and experts all over the world to find suitable bamboos, about 6000 species, of which carbon fibers made of Japanese bamboo are the most practical, which can last for more than 1000 hours, achieving the purpose of durability. This kind of lamp is called "carbonized bamboo filament lamp".

Anecdotal allusions

1, first taste test

When Edison was young, he often went to play in the mill of his neighbor Muir Winchester's house. One day, in Winchester's mill, he saw Winchester doing a flying device experiment with a balloon. This experiment fascinated Edison. He thinks that if a person's stomach is full of qi, he will surely ascend to heaven.

A few days later, Edison mixed several chemical raw materials and gave them to his father's assistant, Michael Oates. Edison told Michael Oates that people would fly after eating this kind of food, and Oates almost fainted after eating Edison's "flying agent". Edison was whipped by his father, and his parents were vigilant, advising their children not to play with Edison and stay away from him.

2. Last words

On Edison's deathbed, doctors and many of Edison's relatives and friends sat around his bed. Seeing his breathing getting weaker and weaker, his heart finally stopped beating. But just as the doctor was about to announce his death, he suddenly sat up again and said a very strange sentence: "I didn't expect it to be so beautiful there." With these words, he died.
