Who invented the bulb and when?

When was the bulb invented and who did it - In today's post we will tell you when the bulb was invented, who did it and all other information related to it.

Who invented the bulb and when

In earlier times, when the bulb was not invented, people used lamps, torches and candles for illumination. 

In such a situation, it was difficult to work at night, as well as many accidents also happened if these things (diya, torch and candle) were not used properly. But since the invention of the bulb, the life of the people has changed. 

After the invention of the bulb, today we can easily do any work in the light at night. Today we are able to travel at night, we can play any sport like cricket, football, hockey at night. So let us know who invented the bulb and when?

What is Bulb?

A bulb is a hollow glass sphere. Which acts like a vacuum from inside. A tungsten filament is attached to this sphere, when electricity is passed through this filament, it heats up in a few moments.After heating from the inside, this filament produces light. There are two wires attached to it to conduct electricity to the bulb. Apart from this, any one gas from Argon, Krypton, Nitrogen, Xenon and Hydrogen is filled at low pressure to make big bulb. Let us know who invented the bulb?

Who invented the bulb?

The bulb was invented by Thomas Alva Edison on 14 October 1879. Edison was a well-known scientist of that time. He invented the carbon filament light bulb. Which by connecting the electric wire used to heat the bulb and start burning. It took him about a year and a half to invent this and when this bulb was lit after being invented, the bulb was lit for more than 13 hours.

Many scientists had done a lot of research and experimentation on this subject even before Edison. For this reason Edison got a lot of help. Edison patented the world's first light bulb. While making the patent in his name, he got that patent named as Improvement in Electric Lights on 14 October 1879. On this research of one and a half years, many metals were used like carbon, platinum were used. But the light of the bulb was limited to 12 hours by the use of platinum metal. But the use of platinum bulb was very expensive. Then from his many experiments, his experiment was successful with the use of metal of carbon filament.       

Edison not only invented the bulb, but he also discovered more than 1000 small and big devices, including – gramophone, motion picture camera, carbon telephone transmitter, alkaline storage battery etc. He was the first person to introduce 'mass production' in the world. He has patents for the invention of 1093 instruments in America.

When was the bulb invented?

Many other scientists had tried to make the bulb, but only Thomas Alva Edison was successful in this. The bulb was invented by Thomas Alva Edison in 1879 AD.

How many types of bulb are there?

There are many types of bulbs available in the market, but the most commonly used bulbs are given below.

  1. Incandescent bulbs

  2. Fluorescent lamps

  3. Compact fluorescent lamps (CFL)

  4. Light Emitting Diode (LED)

  5. Halogen bulbs

Who invented the LED bulb?

Who invented the LED bulb - the world's first L. The ED bulb was invented in 1962 by Nick Holonyak, an engineer working in the US multinational company 'General Electric'. This year has been 57 years since the invention of this bulb. Today it is being used all over the world in place of the incandescent bulb invented by Edison.

History of the invention of the bulb

The bulb was invented by Thomas Alva Edison. He started work on this invention in 1878. Even before Thomas Edison, many scientists were engaged in the discovery of the light bulb. One of these scientists was named Humphry Davy, who invented the first electric bulb in 1802. Humphrey Davy experimented with electricity to create a battery. When he connected the wire to the battery with the carbon applied, the carbon started giving light, thus the first electric bulb was discovered. His invention was named Electric Arc Lamp. But the problem with this invention was that the light did not last long. 

After this, in 1840, British scientist Warren de La Rieu 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 temperatures. Due to which there will be some gas molecules in the chamber which will react with the platinum and the light will last longer than before. But the biggest problem of this experiment was that platinum is very expensive.

After this, in 1850, a scientist named Joseph Swan prepared an electric bulb by using Carbonized Paper Filaments in a glass bulb, but due to good vacuum and lack of electricity, it could not last long. By 1870, good vacuum pumps had come in the market, after which Joseph Swan started his experiment again. On 18 December 1878, he displayed a lamp made with the help of Carbon Road at a Newcastle Chemical Society meeting, but after a few minutes it broke due to excessive use of electricity. After this, he made some changes in it and displayed the working lamp again in the meeting on 17 January 1879.

This experiment was shown again on 3 February 1879 during a meeting of the Literary and Philosophical Society of Newcastle upon Tyne. The carbon rod used in this lamp had a very low resistance, due to which a large conductor was needed to transmit electricity to the lamp, so it was not for general use or marketable. After this his attention went 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 27 November 1880. Thomas Alva Edison patented it on 14 October 1879 under the name Improvement in Electric Lights. He did a lot of experiments, thus the world's first bulb was prepared which could be sold in the market.

Some interesting information related to the invention of the bulb

1.) Amazingly, Edison did not learn to speak until he was 4 years old and had a larger than average head size and an unusually wide front.

2.) In 1954, at the age of seven, Edison started going to school and left school in just 12 weeks! The main reason for which was their hyperactivity and lack of attention, due to which even the teachers could not handle them. In the end his mother made him stop going to school and himself taught him at home till the age of 11.

3.) Edison loved the plays of William Shakespeare and wanted to become an actor. However, due to his very loud voice and shy nature in front of the audience, he had to give up the idea very soon!

4.) Edison is the only scientist in the world who received a patent for some new invention every year for 65 consecutive years (1868-1933).

5.) Thomas Alva Edison had decided that he would not invent any such device which was not in demand in the market and was not sold!

6.) Edison's first invention was a Universal Stock Printer, which he was able to sell along with his other new inventions to General Left, the owner of the Gold and Stock Telegraph Company. 

7.) Early in life Edison worked as a telegraph operator. This work inspired him to make many new devices in the field of telecommunications.

8.) After briefly selling newspapers at the age of 13, Edison decided to start his own newspaper. And started a newspaper called 'Grand Trunk Herald'. He sold this newspaper only to his old customers, which he liked very much and he was also successful in this small business.

9.) In 1876, he established his first laboratory in Menlo Park, California, which later became the world's first industrial research laboratory.

10.) Edison made so many world-changing inventions from the laboratory established in Menlo Park that people began to call him – 'The Wizard of Menlo Park'.

11.) It took Edison a year and a half to make the world's first electric bulb. When it was burnt, it was burnt for more than 13 hours. Its filament was made from carbonized thread.

12.) On December 31, 1879, the laboratory complex in Menlo Park was illuminated with electric bulbs made by Edison. Thousands of people had gathered to see it for the first time. Interestingly, Albert Einstein was also born in the same year.

13.) Thomas Alva Edison's first invention in the laboratory of Menlo Park was a phonograph made of a thin layer of tin. He was also invited by the White House to demonstrate this invention to the US President - Rutherford Birchard Hayes.

14.) A funny thing about Edison is that he made a device to kill even cockroaches! In which they could easily be killed by using electricity.

15.) Thomas Edison was the first person in the world who played a motion picture on the screen on April 23, 1896 with the help of a projector.

16.) Edison was once experimenting with developing a method for separating ore from stones, but he failed and lost millions of dollars. He considered it the biggest failure of his life.

17.) By the year 1870, Thomas Edison was counted among the rich people of America. In the same year he married 'Mary', 16, who worked in his own factory. He had two children from this marriage. They named the two children 'Dot' and 'Dash' in honor of their old Telegraph days.

18.) Unfortunately, his first wife 'Mary' died in the year 1884 and he married the second 'Mina Miller' in 1886.

19.) After his second marriage, Edison moved to West Orange, a city in the state of New Jersey. Here he built another laboratory for his experiments. The laboratory complex consisted of five buildings. In later years they set up factories around the complex for production. This laboratory and factories were spread on about 25 acres of land which provided employment to about 8000-10000 people.

20.) In his most productive years, Edison worked 18 hours a day.

21.) A terrible fire on December 9, 1914 destroyed most of Edison's factories. But still Edison did not panic about it and decided to raise them again with a new resolution. Within a few months, together with his team, he had rebuilt those factories.
