Edison light bulb enclosed in a cage Edison light bulbs , also known as filament light bulbs and retroactively referred to as antique light bulbs or vintage light bulbs , are either carbon- or early tungsten -filament incandescent light bulbs , or modern bulbs that reproduce their appearance.
The lamps on exhibition were incandescent light bulbs with carbon-filaments of high resistance, made of fibres of reed. [5] Two patents were granted to Heinrich Göbel in 1882: an improvement of the Geissler system of vacuum pumps, and a solution to connect carbon-filaments and metal-wires in a light bulb. [6] [7]
