Incandescent bulb 백열등 JULY 17, 2013 04:06 Thomas Edison failed more than 1,200 times in his effort to invent an incandescent bulb. The problem was the filament.

It was a moment of a human being`s creation of the second light after the Prometheus` light. A reporter asked Edison announcing his invention in 1879, "Didn`t you want to give up?" Edison said, "Why give up? I now know 999 different ways that won’t work. " Incandescent bulb is Edison`s core invention among his 1,097 patents. His famous saying, "Genius is 1 percent inspiration and 99 percent perspiration," is all the more true in this incandescent bulb invention. He created a socket, switch, safety fuse, integrating wattmeter, high-efficient power generator and a switch board. The so-called "Edison effect" that he discovered while testing to enhance bulb efficiency was applied to a vacuum tube.
