The Invention of the Light Bulb (1879)
This invention changed the world forever. In 1879, Thomas Edison and his team of researchers invented the first commercially viable light bulb. This revolutionary device allowed for the production of light without the need for open flames, which had been the primary source of illumination for centuries. The light bulb quickly became
An incandescent light bulb, also known as an incandescent lamp or incandescent light globe, is an electric light that produces illumination by Joule heating a filament until it glows. The filament is enclosed in a glass bulb that is either evacuated or filled with inert gas to protect the filament from oxidation. Electric current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections.
