1880 – Thomas Edison receives a patent for his incandescent lamp
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated until it glows.
Thomas Edison began serious research into developing a practical incandescent lamp in 1878.
Edison’s version was able to outstrip all others because of a combination of three factors: an effective incandescent material, a higher vacuum than others were able to achieve and a high resistance that made power distribution from a centralized source economically viable.
January 27, 1880 Thomas Edison receives a patent for his incandescent lamp.
In 1880, the Oregon Railroad and Navigation Company steamer, Columbia, became the first application for Edison’s incandescent electric lamps.
Extra Note: In 1761, Ebenezer Kinnersley demonstrated heating a wire to incandescence.
