Alessandro Cruto was an Italian inventor, born in the town of Piossasco, near Turin, who created an early incandescent light bulb.. Son of a construction foreman, he attended the school of architecture at the University of Turin, while also attending Physics and Chemistry lectures with the dream of crystallizing carbon to obtain diamonds.

1962 Nick Holonyak Jr. develops the first practical visible-spectrum (red) light-emitting diode. 1963 Kurt Schmidt invents the first high pressure sodium-vapor lamp. [17] 1972 M. George Craford invents the first yellow light-emitting diode. 1972 Herbert Paul Maruska and Jacques Pankove create the first violet light-emitting diode.
Swan's first successful electric light bulb and Edison's electric light bulb were both patented in 1879. [44] Circa 1880: the integraph was invented independently by the British physicist Sir Charles Vernon Boys and by the Polish mathematician, inventor, and electrical engineer Bruno Abakanowicz. Abakanowicz's design was produced by the Swiss ...
He invented an incandescent light bulb before Thomas Edison, but it was not commercially profitable. The lamp with a tungsten filament is indeed the only design used now, but in 1906 they were too expensive. Several Lodygin's ideas were implemented much later, even after his death.
An electric light, lamp, or light bulb is an electrical component that produces light. It is the most common form of artificial lighting . Lamps usually have a base made of ceramic , metal, glass, or plastic which secures the lamp in the socket of a light fixture , which is often called a "lamp" as well.
The pendant light at Fire Station #6 in which the bulb is installed. The Centennial Light was originally a 60-watt bulb, but has since dimmed significantly and is now as bright as a 4-watt bulb. [7] [8] [9] The hand-blown, carbon-filament common light bulb was invented by Adolphe Chaillet, a French engineer who filed a patent for this socket ...
His invention of the light bulb in 1876 marked the moment of GE's genesis. If you can Its founder was Thomas Edison, one of America's foremost thinkers, inventors, and tinkerers.
The lamps on exhibition were incandescent light bulbs with carbon-filaments of high resistance, made of fibres of reed. [5] Two patents were granted to Heinrich Göbel in 1882: an improvement of the Geissler system of vacuum pumps, and a solution to connect carbon-filaments and metal-wires in a light bulb. [6] [7]
