Transcript: FONTS Incandescent light bulb History In addressing the question of who invented the incandescent lamp, historians Robert Friedel and Paul Israel list 22 inventors of incandescent lamps prior to Joseph Swan and Thomas Edison. They conclude that Edison's version was able to outstrip the others because of a combination of three factors: an effective incandescent material, a higher vacuum than others were able to achieve (by use of the Sprengel pump) and a high resistance that made power distribution from a centralized source economically viable. Historian Thomas Hughes has attributed Edison's success to his development of an entire, integrated system of electric lighting. The lamp was a small component in his system of electric lighting, and no more critical to its effective functioning than the Edison Jumbo generator, the Edison main and feeder, and the parallel-distribution system. Other inventors with generators and incandescent lamps, and with comparable ingenuity and excellence, have long been forgotten because their creators did not preside over their introduction in a system of lighting. Original carbon-filament bulb from Thomas Edison's shop in Menlo Park Description Bulb, incandescent lamp - electric light source in which the body is glowing filament made of refractory material (originally graphite, tungsten now). Tungsten wire is arranged in a glass bulb filled with a mixture of noble gas (e.g., argon with 10 percent nitrogen doped). The fiber reaches a temperature of around 2500-3000 K by the passage of electric current. The invention was made in the mid-nineteenth century
