Titel
Edison's filament lamp, 1879.
Caption
Made by the American inventor Thomas Alva Edison (1847-1931). Edison's lamp had a single loop of carbon which glowed when a current flowed through it. The glass bulb contained a partial vacuum; there was so little oxygen in the bulb that the filament could get very hot without catching fire., 6960792
