Edison invented the electric lamp and did 1500 experiments, but failed to find a suitable material for the lamp filament. Someone laughed at him and said, "Mr. Edison, you have lost 1500 times." Edison replied, "No, I didn't fail. My achievement is that more than 1500 materials are not suitable for filament of electric lamps. "
From this story, you can also see that he is a man with persistent beliefs. He is optimistic to realize his failure and firm his dreams.
2. What is the main story of Edison's invention of electric light?
As early as 182 1, British scientists David and Faraday invented an electric lamp called an arc lamp. This kind of electric lamp uses an inner carbon rod as the filament. Although it can emit bright light, the light is dazzling and its life is short.
So Edison began to experiment with filament materials. With great perseverance and patience, Edison experimented with 1600 materials and used carbon strips, platinum wires, ruthenium, chromium and other metals as filaments, all of which ended in failure. Edison didn't flinch in the face of failure and some people's cynicism. After 13 months' efforts, Edison tried more than 6,000 kinds of materials and more than 7,000 times. Finally, he found that cotton thread could be used as a filament and burned it for 45 hours. This is the first electric lamp with practical value. This day-1879101October 2 1 day was designated as the electric light invention day. After further experiments, Edison found that bamboo filaments are very effective and durable, and the light bulb can be lit for 1200 hours. After that, the electric light
3. A short story about Edison's invention of electric light.
Introduction to the story:
British scientists David and Faraday invented the arc lamp. This kind of electric lamp uses carbon rods as filaments. Although it can emit light, it is dazzling, consumes a lot of electricity and is not practical. So Edison secretly made up his mind: "We must invent an electric light with soft light so that every household can use it."
He began to study filament materials: from traditional carbon ribbon to ruthenium, chromium, platinum and so on. In this way, Edison experimented with 1600 kinds of materials, but in the face of repeated failures in the experiment, Edison did not flinch. He firmly believes that failure is the mother of success.
1879 10 by chance, Edison tried to put a carbonized cotton thread into the light bulb. When the power is turned on, the light bulb glows golden and illuminates the whole laboratory. After 13 months of hard work, he tried more than 6,000 kinds of materials, more than 7,000 times, and finally made a breakthrough.
The lamp was on for 45 hours before the filament burned out. This is the first electric lamp with practical value. Later, 1879, 10 and 2 1 were designated as the invention days of electric lamps, which marked the birth of usable electric lamps.
But Edison was not satisfied. He wants to extend the life of the light bulb. Later, he tried to use carbonized bamboo filament as filament. The experimental results show that the effect of using bamboo filament is very good, the filament is durable and the bulb can be lit for 1200 hours. So electric lights began to be mass-produced, and from then on, electric lights began to enter the homes of ordinary people.
4. The story of Edison's invention of electric light.
The story of Edison's invention of electric light is very short.
Electric lamp-the messenger of light
/kloc-at the beginning of the 0/9th century, people began to use gas lamps, but gas was supplied by pipelines. Once it is leaked or blocked, it is very prone to accidents, and people are very eager for the reform of lighting. In fact, Edison set himself an impossible task: in addition to improving lighting, he must also create a power supply system.
So he and his partners in Romon Garden worked tirelessly on heat-resistant materials and more than 600 kinds of plant fibers for more than 65,438+0,600 times before making the first carbon filament light bulb, which can burn for 45 hours at a time. Later, he constantly improved the manufacturing method on this basis, and finally introduced a bamboo filament light bulb that can ignite 1200 hours.

Growth stage
Telegraph profession
1862 One day in August, Edison saved a boy on the train track. The boy's father was Mackenzie, the stationmaster of this railway station. He was very grateful for this and taught Edison the telegraph technology. Under the guidance of Mackenzie, Edison learned the telegraph technology and sent his first telegram.
1863, Edison was introduced by Mackenzie as a telecom operator in Stratford Hub Station, but he was soon dismissed.
During the period from 1864 to 1867, Edison worked as a telegraph operator in the United States and lived an insecure vagrant life. During this period, Edison changed ten workplaces, was fired five times, and resigned five times by himself, and traveled all over Stratford, Adrian, fort wayne, Indianapolis, Cincinnati, Nashville, Tennessee and Memphis.

6. A brief introduction to the story of Edison's invention of electric light. 20 minutes, no more than 50 words.
1878, Edison decided to make a cheap light bulb. He put a carbon filament in a glass bulb, but it only lit for 8 minutes, so he changed back to 1600 material and developed a bamboo filament bulb. Until 1906, Edison switched to tungsten wire, which improved the quality of the light bulb and is still in use today.

8. The story of Edison's invention of electric light.
Contrary to popular understanding, Edison was not the inventor of electric light at first, but Edison improved it.
As early as 180 1, a British chemist named Humphrey David used platinum wire to electrify and glow in the laboratory. 18 10, he invented the "electric candle" which was illuminated by the arc between two charged carbon rods, which was the earliest prototype of the electric lamp. Joseph swan, another British electrical engineer, after nearly 30 years' research, made a vacuum bulb with electricity and light from carbon wire in 1878+02.
The report about the swan's light bulb gave Edison a great inspiration. 1879 10, Edison finally succeeded in making an incandescent light bulb with carbon fiber as the filament, which is called "carbonized cotton filament incandescent lamp". Later, a large number of incandescent lamps were put into production, and companies were established to establish corresponding power stations, transmission networks and other infrastructure, which soon made electric lamps widely used in the United States.
During this period, he constantly improved his technology, and finally decided to use tungsten wire as the filament, which is called "tungsten lamp" and has been used ever since, so Edison became a recognized inventor of electric lamp.
(8) Introduction to the story of the person who invented the electric light Extended reading:
The United States Patent Office ruled that Edison's invention of carbon filament incandescent lamp lagged behind others, and the patent was invalid. After years of litigation, Henry Goebbels won the patent, and finally Edison bought the patent from Goebbels poor widow. In Britain, Swan accused Edison of patent infringement. Later, they settled out of court and set up a joint venture company in Britain on 1883.
Swan later sold his shares and patents to Edison.
