WebNov 29, 2024 · The incandescent light bulb turns electricity into light by sending the electric current through a thin wire called a filament. Electrical filaments are made up mostly of tungsten metal. The resistance of the filament heats the bulb. Eventually the filament gets so hot that it glows, producing light. Evolution of light bulb WebEdison continued to improve this design and by November 4, 1879, filed for a U.S. patent for an electric lamp using "a carbon filament or strip coiled and connected to platina contact wires." On January 27, 1880 U.S. patent number 223,898 was granted to Edison for what would become the first perfected commercially viable incandescent lamp.
