In today’s time, it would not be wrong to say that the invention of electric bulb has worked to remove the darkness of human life, in ancient times people used to use lamp, torch or candle for lighting. But in this way many accidents used to happen if these things were not used properly.
Earlier it was difficult to do anything at night, but after the invention of the bulb, we can easily do any work at night, like traveling at night, playing any game like cricket, football, hockey. Or we can easily do any work related to office, home or shop.
History of the invention of the Bulb
By the way, let me tell you that it would not be right to attribute any major invention to any one person, but the credit for the invention of the bulb goes to Thomas Alva Edison, who did this wonderful work on October 14, 1878. This invention of Thomas Alva Edison revolutionized the world of light and only Edison was discussed everywhere.
Some unheard stories of Thomas Alva Edison
Yes, Edison is the same great scientist whom we have read a lot in books for his different inventions, it is believed that Edison invented more than 1000 small and big devices in his entire life, such as light bulb, gramophone, Motion picture cameras, carbon telephone transmitters, alkaline storage batteries are the main ones.
One of Edison’s great inventions is the light bulb, which he failed more than 10,000 times, but on this he said, “I never failed, but I found more than 10,000 ways to make something work for me.” Friends, his life story is full of motivation, will come with another complete video someday
Controversy over the invention of the Bulb
It is said that the idea of making an electric bulb first came to a scientist named Humphrey Davy around the year 1800 and he also did a lot of research but he could not succeed, then in 1840 a British scientist Warren the La Rue placed coiled platinum filament in a vacuum tube and passed electric current through it. ,
The purpose of this experiment was that the High Melting Point of platinum would keep it under control at high temperature, but this experiment could not be successful due to the high cost of platinum.
After this, around 1850, Joseph Swan prepared an electric bulb using Carbonized Paper Filaments in a glass bulb, but due to good vacuum and lack of electricity, it could not last long.
But Swan did not stop now and kept making new efforts day by day and one day he turned his attention to the improvement of Carbon Filament which he prepared with the help of Cotton which was named Parchmentised Thread.
He obtained the patent for this filament on November 27, 1880, but before that Thomas Alva Edison had patented the Electric Lights bulb in 1878. And Edison also accused Swan of stealing his idea.
But later when Swan showed his research papers of his years, everyone had to accept it and later these two people together prepared improved carbon filament light bulb which could be used by common people.
what is a light bulb and how does it work
Bulb is an electrical device. It is covered by a glass frame inside which a filament made of tungsten, nitrogen gas and some inert gas are filled. The bulb is well sealed. So that oxygen cannot enter inside it. Tungsten filament is used in the bulb because when electricity passes through the tungsten wire, tungsten glows due to the resistance and we see the bulb burning.
Benefits of invention of Bulb
As if the invention of the bulb has changed the picture of the whole world, the bulb is widely used for research and medical, in travel, to express happiness on the occasion of any festival, wedding or celebration. Due to the invention of the bulb, it became easy to study, there was a huge expansion in jobs, business etc. It can be said that even if a person is progressing in today’s time, it is due to the contribution of the light bulb. only possible
Types of Light Bulbs
There are many types of bulbs available in the market. But the most commonly used bulbs are given below.
Compact fluorescent lamps (CFL)
Light-emitting diode (LED)
- Sir Humphrey Davy invented the Davy lamp in 1800 but it was not successful
- The light bulb was invented in 1850 by Joseph Swan using carbonized paper filaments, which were later updated
- Thomas Edison is a scientist who received a patent for some new invention every year for 65 consecutive years (1868 to 1933).
- The LED bulb was invented in 1962 by Nick Holloway Naik, an engineer working at the American company General Electric.
- The full name of bulb is incandescent lamp.
- The filament of the bulb is made of tungsten which is protected by an inert gas.
