  2. Edison light bulb - Wikipedia

    en.wikipedia.org/wiki/Edison_light_bulb

    Original carbon-filament bulb from Thomas Edison's shop in Menlo Park. Light bulbs with a carbon filament were first demonstrated by Thomas Edison in October 1879. [1] [2] These carbon filament bulbs, the first electric light bulbs, became available commercially that same year. [3]

    Goebel claimed his lamp contained a high resistance filament of carbon, platinum lead-in wires in an all-glass envelope, and a high vacuum produced with the Torricellian method using mercury. He tried several materials to produce the carbon filaments and discovered the advantages of bamboo.

  4. Centennial Light - Wikipedia

    en.wikipedia.org/wiki/Centennial_Light

    The bulb was made by hand, using a carbon filament (of greater thickness and strength than the tungsten filaments used in most modern lightbulbs) along with brass and glass components of high quality. The low wattage (originally 60 watts, now approximately four) and high nitrogen atmosphere inside the bulb have also contributed to its longevity.

    Lodygin later sold the patent rights to GE. In 1902, Siemens developed a tantalum lamp filament that was more efficient than even graphitized carbon filaments since they could operate at higher temperature. Since tantalum metal has a lower resistivity than carbon, the tantalum lamp filament was quite long and required multiple internal supports.

  6. Halogen lamp - Wikipedia

    en.wikipedia.org/wiki/Halogen_lamp

    A carbon filament lamp using chlorine to prevent darkening of the envelope was patented [2] by Edward Scribner of the US Electric Lighting Co. in 1882, and chlorine-filled "NoVak" lamps were marketed in 1892. [3] The use of iodine was proposed in a 1933 patent, [4] which also described the cyclic redeposition of tungsten back onto the filament.

  7. Alessandro Cruto - Wikipedia

    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.
