An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated to such a high temperature that it glows with visible light (incandescence). The filament is protected from oxidation with a glass or fused quartz bulb that is filled with inert gas or a vacuum.
(Historical footnote: One can’t talk about the history of the light bulb without mentioning William Sawyer and Albon Man, who received a U.S. patent for the incandescent lamp, and Joseph Swan, who patented his light bulb in England. There was debate on whether Edison’s light bulb patents infringed on these other inventors’ patents.
The incandescent light bulb first shone after years of work by many notable figures who contributed to the development of this revolutionary technology. Thomas Edison built on their successes and ...
The electric light bulb, specifically the incandescent light bulb, has become synonymous with the term light bulb for many years. Whilst it is but one of various artificial lighting solutions ...
On February 11, 2011, on what would have been Thomas Edison's 164th birthday, Google's homepage featured an animated Google Doodle commemorating his many inventions. When the cursor was hovered over the doodle, a series of mechanisms seemed to move, causing a light bulb to glow. List of people who worked for Edison
The person who invented it first is difficult to point out. The first to come up with the idea was Sir Humphry Davy. Edison and Swan were the first to create commercially viable incandescent bulbs and popularize them. In every discovery and invention, many hands and heads are involved.
On October 21st, 1879, in one of the most famous scientific tests in history, Thomas Edison debuted his signature invention: a safe, affordable, and easily-reproducible incandescent lightbulb that burned for thirteen and a half hours. Bulbs tested following that lasted for 40 hours. Although Edison cannot fairly be credited as the sole inventor of the lightbulb, his final product—the result ...
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.
1841 Frederick de Moleyns patented a incandescent lamp within a glass bulb and a partial vacuum. He is one of many people working on the incandescent light bulb from 1840 to the 1870s. Many French and Germans contributed to research on the incandescent bulb.
It was two earlier inventors, Henry Woodward, and Matthew Evans, who invented the incandescent light bulb, whose patent was purchased by Thomas Edison. By 1879, Edison had switched to a carbon filament and the oxygenless enclosure, and had produced a bulb that would last for forty hours. The incandescent bulb has come a long way since then.
