Thomas Edison is credited with perfecting the first commercially practical incandescent light bulb in 1879. He filed for a patent for his invention and his improvements made the light bulb more efficient and long-lasting.
The patent is in Edison's name (see related link).
Joseph Swan and Thomas Edison independently invented the incandescent lightbulb. Swan filed for a patent in England in 1878, while Edison filed for a patent in the United States in 1879. Both inventors made significant contributions to the development of the lightbulb as we know it today.
The incandescent light bulb,Another Answer:Actually Edison did NOT invent the Incandescent Light Bulb, he bought the original Patent, and then LATER improved the Filament, so that it become a longer lasting, more reliable product.

Incandescent Electric Light Bulb
The Incandescent Lamp
If you are asking about the first light bulb it was Edison.
Sir Joseph Swann of England and Thomas Edison both developed workable electric incandescent lamps during the 1870s. Edison's lamp became the first commercially successful incandescent lamp (circa 1879). Edison received U.S. Patent 223,898 for his incandescent lamp in 1880.However, contrary to popular belief, Edison did not "invent" the first lightbulb, he improved upon a 50-year-old idea. Canadians Henry Woodward and Matthew Evans patented a light bulb in 1875, but could not raise the financing to commercialize their invention. Edison bought the rights to their patent
Swan invented the light bulb in 1878. Edison spent a year trying to improve it and filed a patent in the US a year later. The two men never met but decided to settle out of court and formed the Ediswan company

The creator of the first working light bulb was Joseph Wilson Swan. Swan's house was the first place in the world to be lit by a light bulb (and hydroelectric power). He patented the light bulb in England. Thomas Alva Edison improved Swan's light bulb by using a better incandescent material and a higher vacuum and patented it in the US. Rather than fighting for the ownership of the patent, Swan and Edison formed the Edison & Swan United Electric Light Company.
