Who Invented The Light Bulb Filament

He did not invent the light bulb but he did develop a safe affordable and durable incandescent light bulb that could produce light for hundreds of hours.

Who invented the light bulb filament. Yet the british chemist warren de la rue had solved the scientific challenges nearly 40 years earlier. He sold the patent to the us electric co. These new tungsten filament bulbs lasted longer and had a brighter light compared to the carbon filament bulbs. Us inventor thomas edison is often credited with creating the solution in 1879.

Edit september 2020 the former vice president joe biden made a controversial statement saying that a black man invented the light bulb not a white guy named edison. The edison electric light company in new york city hired latimer in 1884 as a draftsman and an expert witness in patent litigation on electric lights. In 1910 william david coolidge developed the tungsten filament capable of burning brighter and longer than carbon filaments. Tungsten has the highest melting point of any element and is still used in incandescent bulbs to this day.

Who invented the electric light bulb as we know it today. In 1913 irving langmuir figured out that placing an inert gas like nitrogen inside the bulb doubled its. Latimer received a patent on january 17 1882 for the process of manufacturing carbons an improved method for the production of carbon filaments for lightbulbs. Maxim was the chief rival to thomas edison the man who invented the electric light bulb.

Who invented the twisty little bit of wire inside the light bulb. Edison s light had been composed of a glass bulb which surrounded a carbon wire filament typically made of bamboo paper or thread. The filament is enclosed in a bulb to protect the filament from oxidation current is supplied to the filament by terminals or wires embedded in the glass. Latimer created a light bulb with a more durable filament made of carbon.

The carbon filament light bulb. The light was composed of a glass bulb which surrounded a carbon wire filament generally made of bamboo paper or thread. We all learned in our history classes that thomas edison invented the light bulb in 1879 and that the first successful filament was a carbonized piece of cotton thread that burned for 13 5 hours. When the filament was burned inside of the bulb which contained almost no air it became so hot that it actually glowed.
