Where does the light bulb originate from?

The light bulb originated from the work of several inventors in the 19th century, with Thomas Edison often credited for its widespread commercialization in 1879. However, earlier designs emerged from inventors like Humphry Davy, who created an electric arc lamp in the early 1800s, and Joseph Swan, who developed a working incandescent lamp around the same time as Edison. Edison's improvements included a more efficient filament and a practical vacuum bulb, which enabled longer-lasting illumination. This innovation marked a significant advancement in electric lighting technology.
