As the current flows threw the filament it excites the atom shell electrons. This cause the electrons to jump to a higher orbit. Then the atoms fall back to their lower orbit and release energy that are photons. The photons are pure energy and travel at the speed of light. That is light.
What do you think about the light bulb? I think it is one of humanity biggest inventions.
Let me know what you think in the comments.
