Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman known for his work on the incandescent light bulb, the phonograph, electric power distribution and early motion pictures. The merger of the Edison General Electric Company and the competitor Thomson-Houston Electric Company resulted in the formation of General Electric. Edison registered 1,093 patents in the United States. Edison was born in Milan, Ohio, but grew up in Michigan with little formal schooling. He became deaf as a child and learned through books and tinkering. Edison began working at a young age; as a railroad telegrapher, he spent much of his time inventing improvements to telegr…

Edison screw (ES) is a standard lightbulb socket for electric light bulbs. It was developed by Thomas Edison (1847–1931), patented in 1881, and was licensed in 1909 under General Electric's Mazda trademark. The bulbs have right-hand threaded metal bases (caps) which screw into matching threaded sockets (lamp holders). For bulbs powered by AC current, the thread is generally connected to neutral and the contact on the bottom tip of the base is connected to the "live" phase. In North America and continental Europe, Edison screws displaced other socket types for general lighting. In the early days of electrification, Edison screws were the only standard connector, and appliances other than lig…

Thomas Edison’s Patent Application for the Incandescent Light Bulb. In the late 1870s gaslight was the primary means used to light residential homes and most businesses. Electric lighting had been conceived of decades earlier, but no one had been able to produce electric lighting in a safe, feasible, affordable manner. A number of inventors were working on this problem, but Thomas Edison was the first to develop a long-lasting, practical light bulb. His patent application for that light bulb was filed with the United States Patent Office on November 4, 1879, and his patent was granted on January 27, 1880.

Thomas Edison: Patent No. 223,898 for the Light Bulb. Perhaps no invention defines the Gilded Age in the United States like Thomas Edison’s light bulb; only Alexander Graham Bell’s telephone rivals it in importance. The ability to flip a switch and turn darkness to light has had an impact equivalent to that of fire or the wheel or air conditioning on human life in the modern era. Candles, oil, kerosene, and gaslight had previously allowed people to live their lives past sundown, but all of them were expensive and carried an element of danger in the exposure to open flame. Edison’s light bulb was cheap and safe and therefore transformed the workplace, the home, and leisure spaces. Longer wor…

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. Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts. They require no external regulating equipment, have low manufacturing costs, and work equall…

An electric light, lamp, or light bulb is an electrical device that produces light from electricity. It is the most common form of artificial lighting. Lamps usually have a base made of ceramic, metal, glass, or plastic that secures them in the socket of a light fixture. The electrical connection to the socket may be made with a screw-thread base, two metal pins, two metal caps or a bayonet mount. The three main categories of electric lights are incandescent lamps, which produce light by a filament heated white-hot by electric current, gas-discharge lamps, which produce light by means of an electric arc through a gas, such as fluorescent lamps, and LED lamps, which produce light by a flow o…
