How many times did Edison fail to invent the electric light?

It seems to have been used about 7,200 times.

I can tell you very clearly and responsibly: n+1 times.

Edison's invention of the electric light took about 1,600 times to succeed. On October 21, 1879, the electric light was developed. To do this, Edison experimented with nearly 1,600 materials.

After 45 hours of continuous use, the filament of this lamp was burned off. This is the first lamp of mankind with a wide range of practical value. This type of electric lamp has various names such as "high-resistance incandescent lamp" and "carbonized cotton filament lamp", and is made of carbonized cotton silk.

The twists and turns of Edison's invention of the electric light:

In 1874, two Canadian electrical technicians applied for a patent for an electric lamp: filling a glass bubble with nitrogen to emit light on a charged carbon electrode, but the electrical technicians did not have enough money to continue perfecting the invention, so they sold the patent to Edison in 1875. Edison bought a patent and tried to improve this filament.

Eventually, in 1880, Edison produced a carbonized bamboo filament lamp that lasted 1,200 hours. However, the U.S. Patent Office ruled that Edison's invention of carbon fiber incandescent lamps was invalid. After years of litigation, Henri Goebbels won the patent, which Edison eventually bought from Goebbels' impoverished widow.

In the United Kingdom, Swan sued Edison for patent infringement. Later, it was reconciled outside of the court and a joint venture was formed in 1883. Swan later sold his shares and patents to Edison.

He failed many times and never succeeded, but Edison never gave up, and he worked hard to find it, and finally succeeded in inventing it.

Edison went through many experiments in order to invent the electric light bulb, and it was not until after 6,000 failures that he succeeded in inventing the electric light bulb, so that we could use normal light bulbs.

He failed more than a thousand times, but in the end he succeeded in inventing the electric light, and his perseverance and perseverance are worthy of recognition, proving that failure is the mother of success.

Edison failed many times when he invented, and it was the lessons learned from each failure that led him to great inventions.

Electric light was not invented by Edison. However, Edison improved the way electric light bulbs were made.

In 1879, the Englishman Svan invented the method of making the electric light bulb, but he did not apply for a patent, but published the method of making the electric light bulb in a scientific journal. When Edison saw this scientific journal, he made an electric light bulb and applied for a patent.

Because Edison had a patent, it is mostly believed that Edison invented the electric light. Later, it was discovered from the work diary of Edison's laboratory that on the day he was "inspired" to invent the electric light, he entered the laboratory with the scientific journal with Svan's article. So, there is reason to suspect that Edison's "inspiration" came from that magazine!

Nowadays, many authoritative dictionaries and textbooks no longer say that "Edison invented the electric light". For example, "Cihai" only said that he "experimented and improved incandescent lamps and **", but did not say "invented".

The "Edison" entry in Cihai.

Edison's invention of the electric light failed 1,600 times.

On October 21, 1879, the electric light was developed.

Edison tried nearly 1,600 kinds of materials for experiments, when the last material made of electric lamp filament was burned out after 45 hours of continuous use, this is the first electric lamp with wide practical value in human beings, the filament of this electric lamp is made of carbonized cotton silk, so there is"Carbonized cotton filament lamp"、"High resistance incandescent lamps"and other names.

Many times.

Actually, there is no specific number of times.

There are three kinds of theories that have been circulated more than 1,000 times, 1,600 times, and 8,000 times.

In fact, there are only more than 1,600 or so that I have tried more than 1,600 kinds of materials, according to some accounts.

To say more, it doesn't really make much sense to invent this kind of thing and count how many failures there are. Because the process of invention itself is a process of "constantly eliminating wrong options", it is said that "failure is the mother of success".

1600 times.

Edison's invention of the electric light failed 1,600 times. On October 21, 1879, the electric lamp was successfully developed, for which he tried nearly 1,600 kinds of materials for testing, and after 45 hours of continuous use, the filament of the electric lamp was burned out, which was the first electric lamp with extensive practical value.

Edison's invention of the electric light was successful after countless failures, and this cannot be counted in terms of times.
