Who Invented the Light Bulb? Tungsten, which has the highest melting point of any chemical element, was known by Edison to be an excellent material for light bulb filaments, but the machinery needed to produce super-fine tungsten wire was not available in the late nineteenth century.

Where Was the Light Bulb Invented? Before Swan, the earliest predecessor of the light bulb was Humphry Davy's electric light in 1802. However, the first person to enclose a light in a vacuum was Warren de la Rue in 1840. Because it was made with platinum, it was not a cost-effective way of producing light.

Thomas Edison Thomas Alva Edison (February 11, 1847 - October 18, 1931) was an American inventor, who invented many things. Thomas Edison developed one of the first practical light bulbs, but contrary to popular belief did not invent the light bulb. Edison's 1093 patents were the most granted to any inventor in his time.

Thomas Edison Lightbulb This is an early sketch from Thomas Edison of his light bulb. Thomas Edison’s serious incandescent light bulb research began in 1878, filing his first patent later that year…”Improvement In Electric Lights” in October 1878. His experiments involved the fabrication and testing of many different metal filaments, including platinum.

- Edison was neither the first nor the only person trying to invent an incandescent electric lamp. In the U.S., Moses Farmer, William Sawyer and Albon Man, and Hiram Maxim were all pursuing the goal, as were St. George Lane-Fox and Joseph Swan in England.

Edison continued to improve this design and by November 4, 1879, filed for U.S. patent 223,898 (granted on January 27, 1880) for an electric lamp using a carbon filament or strip coiled and connected to platina contact wires.

WHY PEOPLE LIE & SAY THAT LEWIS LATIMER INVENTED THE carbon filament in 1881 or 1882? No! English chemist/physicist Joseph Swan experimented with a carbon-filament incandescent light all the way back in 1860, and by 1878 had developed a better design which he patented in Britain. On the other side of the...

Thomas Edison is usually credited with the invention of the light bulb, but the famous American inventor wasn't the only one who contributed to the development of this revolutionary technology.ike earlier renditions of the light bulb, Swan's filaments were placed in a vacuum tube to minimize their exposure to oxygen, extending their lifespan. Unfortunately for Swan, the vacuum pumps of his day were not efficient as they are now, and his first prototype for a cost-effective bulb never went to market.

Thomas Edison Lightbulb Continuing to improve his design, by November 1879, he filed for a U.S. patent for an electric lamp using “a carbon filament or strip coiled and connected … to platina contact wires”. The filament was made from a piece of carbonized thread. From coneption to invention, this is one of Thomas Edison's early light bulbs.

- In addition, Edison did not simply come up with the idea on October 21, 1879. He had been working on his light bulb since 1877. He had been trying to come up with a material that could be used as a filament for the light bulb without burning out too quickly. He tried many different substances.homas Edison invented the light bulb in 1879. Edison discovered that a carbon filament in an oxygen-free bulb glowed but did not burn up for 40 hours. Edison eventually produced a bulb that could glow longer. Yojana_Thapa | Student, Grade 10 | TA | (Level 1) Valedictorian.

History of the Light Bulb A Brief History of the Light Bulb. The electric light, one of the everyday conveniences that most affects our lives, was not “invented” in the traditional sense in 1879 by Thomas Alva Edison, although he could be said to have created the first commercially practical incandescent light.n 1802, Humphry Davy invented the first electric light. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. His invention was known as the Electric Arc lamp.

The History of Lighting and Lamps Edison's  lamp became the first commercially successful incandescent lamp  (circa 1879). Edison received U.S. Patent 223,898 for his  incandescent lamp in 1880.    However, contrary to popular belief, Edison did not invent the  first lightbulb, he improved upon a 50-year-old idea. Canadians  Henry Woodward and Matthew Evans patented a light bulb in 1875, but  could not raise the financing to commercialize their invention.  Edison bought the rights to their patent.

What Date was the light bulb invented? In 1903 Willis Whitnew invented a filament that would not blacken the inside of a light bulb. It was a metal-coated carbon filament. In 1906, the General Electric Company was the first to patent a method of making tungsten filaments for use in incandescent light bulbs.

What Date was the light bulb invented? The invention of the light bulb is usually attributed in Britain to Joseph Wilson Swan and in the United States to Thomas Alva Edison (the first to market the device successfully). Alexander Nikolayevich Lodygin independently developed an incandescent light bulb in 1874.

In 1893, the German inventor Heinrich Göbel claimed he had developed the first light bulb in 1854: a carbonised bamboo filament, in a vacuum bottle to prevent oxidation, and that in the following five years he developed what many call the first practical light bulb.

History of the Light Bulb In 1850 an English physicist named Joseph Wilson Swan created a “light bulb” by enclosing carbonized paper filaments in an evacuated glass bulb. And by 1860 he had a working prototype, but the lack of a good vacuum and an adequate supply of electricity resulted in a bulb whose lifetime was much too short to be considered an effective prodcer of light.

- There were other experiments on incandescent light before  and after, but this was the first incandescent light bulb, as the  platinum filament was enclosed in a vacuum tube.    Sir Joseph Swann of England and Thomas Edison both developed  workable electric incandescent lamps during the 1870s.
