1813 National Heat and Light Company formed by Frederick Albert Winsor. 1815 Humphry Davy invents the miner's safety lamp. 1823 Johann Wolfgang Döbereiner invents the Döbereiner's lamp. 1835 James Bowman Lindsay demonstrates a light bulb based electric lighting system to the citizens of Dundee.
The first commercially successful light bulb filaments were made from carbonized paper or bamboo. Carbon filaments have a negative temperature coefficient of resistance—as they get hotter, their electrical resistance decreases. This made the lamp sensitive to fluctuations in the power supply, since a small increase of voltage would cause the ...
The earliest street lights in the colonial America were oil lamps burning whale oil from the Greenland or Arctic right whales of the North Atlantic, or from sperm whales of the South Atlantic, South Pacific, and beyond. [1] [3] Lamplighters were responsible for igniting the lamps and maintaining them. [3]

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 ...
A photo of the original purchase order from Thomas Edison to Corning for the glass encasement for Edison’s lightbulb in 1880. CEO Wendell Weeks keeps the purchase order framed in his office as a ...
Lewis Howard Latimer (September 4, 1848 – December 11, 1928) was an American inventor and patent draftsman. His inventions included an evaporative air conditioner, an improved process for manufacturing carbon filaments for electric light bulbs, and an improved toilet system for railroad cars.
English engineer Joseph Swan invented the Incandescent light bulb. 1879: American physicist Edwin Herbert Hall discovered the Hall Effect. 1879: Thomas Alva Edison introduced a long-lasting filament for the incandescent lamp. 1880: French physicists Pierre Curie and Jacques Curie discovered Piezoelectricity. 1882
