If you are asking who invented the first light BULB, that would be Humphry Davy.
"The 1st light bulb was built by Humphry Davy (an Englishman) in 1809. Thomas Alva Edison improved the invention and based his improvements on a patent he purchased from inventors Henry Woodward & Matthew Evans who patented their bulb in 1875."
