Nov 22, 2013 · Like all great inventions, the light bulb can’t be credited to one inventor. It was a series of small improvements on the ideas of previous inventors that have led to the light bulbs we use in our homes today. Learn more about the history of the incandescent light bulb. Explore the history of fluorescent lights, from the Geissler tube to CFLs.
A Brief History of the Light Bulb. The electric light, one of the everyday conveniences that most affects our lives, was not “invented” in the traditional sense in 1879 by Thomas Alva Edison, although he could be said to have created the first commercially practical incandescent light.
For each use, the individual bulb differs in size and wattage, which determine the amount of light the bulb gives off (lumens). However, all incandescent light bulbs have the three basic parts—the filament, the bulb and the base. Originally produced by hand, the light bulb manufacture is now almost entirely automated.
Thomas P. Pearsall developed high brightness light-emitting diode in 1976, for use with fiber optics in telecommunications. Shuji Nakamura of Nichia Corporation made first blue LED in 1979 but it was too expensive for commercial use until 1994. Light emitting diodes can now be made in one or in more colors.
The modern incandescent light bulb, with a coiled filament of tungsten, and commercialized in the 1920s, developed from the carbon filament lamp introduced about 1880. Less than 3% of the input energy is converted into usable light.
A glowing vintage light bulb of "ST" shape While the intricate filament design never fully left, innovations in energy efficiency outpaced the highly inefficient design quickly. Still, 51 years after more efficient designs had come into play, "Edison-style" or vintage lights saw resurgence in many businesses and homes wanting atmospheric ...
There are several kinds of light bulbs: incandescent light bulb - the most common light bulb in the house until about 2003-2010 'halogen lamp' - a more efficient incandescent bulb; gas discharge lamp - a type of light bulb that includes the fluorescent light. Compact fluorescent lights (or CFLs) are now replacing incandescent light bulbs in the ...
