The truly modern bulb is the result of a 1904 invention by Sándor Just and Franjo Hanaman. They created a tungsten filament that worked better in an argon or nitrogen atmosphere.

Filament bulbs and other commonly used light sources emit ... but like the bulb Edison developed,” said ... the UMich team ...

You can't buy incandescent light bulbs anymore. With a few exceptions, the bulbs – patented by Thomas Edison in 1880 and a common fixture in American homes for more than a century – have ...

By integrating micro- and nanoscale twists into the tungsten filament structure, the light wave inherits that helical shape, effectively making it elliptically polarized.

Edison and light bulb. ... The filament is made of tungsten, which resists high temperatures magnificently. Electricity is fed to the tungsten, which almost immediately glows white hot.

Incandescent bulbs produce light by using electricity to heat a wire filament until it glows. The drawback is that the bulbs use 90% of their energy to produce heat . CFLs use about 80% for heat.

The original Thomas Edison-patented bulbs — characterized by the burning-hot tungsten filament inside — cast a particular mood around a space. Interior designers and many homeowners adore ...

Edison’s first practical light bulb used a carbonized cotton thread for that purpose; modern bulbs use tungsten filaments in an inert gas. But incandescents are not very efficient.
