First of all, Edison did NOT invent the light bulb, and he never made that claim. His success was in developing a light bulb that would last long enough that they could be manufactured and sold for a profit. The difference between an invention and a profitable invention is extremely crucial, to be certain, but they are NOT the same thing.
Anyway, Edison began work on improving light bulbs began in 1878. His first patent was filed on 1878 October 14, and his first practical light was patented on 1879 November 9.
