1879, Thomas Edison came up with a new idea and invented a lamp with high endurance in a large vacuum, it will burn for hundreds of hours. At December 31, 1879, Edison announced the invention of his incandescent light in public and do change the world completely at the time.
However, the people invented the incandescent bulb, the calendar Robert Friedel and Paul Israel uses listed 22 inventor Joseph Swan lamps front and Thomas Edison (1847-1931). They concluded that the version of Edison's incandescent light than other versions by combining three elements: more efficient burning of materials, degree of vacuum in the bulb above the other versions (using the Sprengel pump) and higher resistor makes power distribution from a central source could be done economically.
