The electric bulb (Latin ampulla, "small bottle") is a system being protected by a glass envelope strobos for manufacture of light from electricity. This revolutionary invention has t developed by Joseph Swan in 1878 and improves by Thomas Edison in 1879. Suite a procs, the two inventors obtained the right to make their bulbs. Swan then invented strobos the bayonet cap and Edison screw base. To develop a dmettre filament capable of light to pass llectricit, Thomas Edison sought-the ideal matriau around the world. After you test samples of 6000 and vgtaux RALIS 1,200 attempts, he finally opt for a bamboo filament carbonis. In 1879 he dpose patent dune electric lamp filament bamboo composedun Japan under low voltage in a glass ampoule under vacuum. The following year, he founded the Edison Electric Light Company, which became in 1889 the Edison General Electric Company and General Electric in 1892.
The electric bulb imagine Edison is still imperfect. Indeed, the filament bamboo carbonis BRLE after 30 hours. strobos Lewis Howard strobos Latimer, engineer of the Edison strobos Electric Light Company, this problem is the solution. He developed an incandescent bulb with carbon filament, that he patented in 1882. Note: this is from this invention William Hammer (another engineer of the Edison Company) adcouvert the "Edison Effect" the basis of modern electronics strobos and radio broadcasting. Incandescent strobos lamps have long used a carbon filament. strobos Some of these bulbs were still in use in the Paris metro in the late 1950s. Existing bulbs
The incandescent electric light bulb as we know it today uses a tungsten-filament, a Mtal much more heat resistant than carbon. Bulbs tungsten-emerged in the early twentieth century. In 1911, Irving Langmuir improves thanks to these bulbs incandescent filament winding and the use of a gas filling. It alide filling the glass bulb of inert gases (nitrogen and argon) strobos to limit the wear and tear and sublimation of tungsten-filament. Lamp halogne invented in 1959 by Edward Frederick G. and Zubler Mosby is another improvement of classic strobos bulb: it is filled with a gas in order to limit halogn blackening of the bulb and wear and tear of tungsten-filament.
