"Prometheus had stolen the fire to humans, but Edison brought the light to humans." On October 21, 1879, a glass expert, according to Edison's instructions, pumped the air in the bulb to the air with only atmospheric pressure. One in ten thousand, and sealed up. Edison turned on the current, and the day and night hope finally came out - the light bulb glowed golden! This day was later designated as the day of the invention of electric lights.
Many of Edison's inventions were exhibited at the early World Expo and were widely known to the world through the World Expo. At the same time, many of his inspirations came from the World Expo. The 1878 Paris World Expo marked an important stage of electrical engineering. The wonderful exhibition content of the Expo lighting has benefited Edison. But the so-called electric lights at the time were not the current concept lights.
[Interview] He Shunguo, Professor of History Department of Peking University has a great influence on him. At the time, everyone was very interested in various inventions such as electric lights, so this prompted him to come back to focus on the inventions related to electric lights, and in the second year, in 1879, incandescent lamps were invented.
In recalling the unforgettable moment of inventing the electric light, Edison said: "We sat there watching the lamp continue to burn. The longer it burns, the more we feel so fascinated. No one among us can go to sleep. There were 40 hours of work, and none of us went to sleep. We sat and watched the lamp from the heart. It continued to burn for about 45 hours."
On the last cold, snowy night in 1879, Edison used the magical new light source to illuminate the Monroe Park pilot plant. Visitors came from all directions, and 3,000 people were packed with laboratories that could only accommodate 30 people. In 1880, Edison obtained the patent for the invention of electric lights. The New York Times called him "a man of ordinary light."
After that, Edison has been working on the improvement of incandescent lamps. In order to improve the quality of the bulbs and extend the life of the bulbs, Edison tried every means to find the materials suitable for the filaments. He has tested about 6,000 plant fiber materials.
At the Paris Electric Power Fair in 1881, Edison exhibited the power supply generator he invented to power thousands of bulbs. The fair was brightly lit and illuminated the entire hall. This invention shocked the whole of Europe. Groups of visitors from all over the world were fascinated by this mysterious electric. Unlike a steam engine, its power is invisible. A Frenchman wrote: "We haven't gotten used to a machine driven by objects that are not obvious. They are as confusing as metaphysics, their secrets, we can't figure it out for a while." At that time, one of the exhibitions was called Ratno. The German, on the spot, on behalf of the German government bought Edison's invention patents, and soon formed a German Edison Applied Electric Company. France, the United Kingdom, Italy, the Netherlands and Belgium have since followed the emergence of commercial companies that operate electric light production and distribution systems, and electric lights have illuminated more and more corners of the world.
At the Paris World Expo in Paris in 1889, Edison used the invented incandescent lamp to decorate the Eiffel Tower. The towering towers were full of brilliance and became the most dazzling star of the Expo.
In 1893, at the Columbus Memorial in Chicago, Edison used the invented nitrogen lamp to illuminate the entire exhibition hall. On October 21, 1915, the Panama Pacific World Expo set up the "Eddie Birthday". Edison personally attended the "Eddie Birthday" and pointed to a spare candle and said: "I once said that when the lights are popular, only the luxury people use candles."
[Interview] Li Qirong, Professor of History and Culture College of Central China Normal University The birthday of Eddie reflects the love and admiration of Edison by people all over the world. The main exhibits at this World Expo are some electric drive tools, as well as some tools for making food using electricity.
In 1979, the United States held a year-long commemoration to commemorate the 100th anniversary of Edison’s invention of electric lights.
