The light in the bulb is most certainly not from fire.
If its an actual bulb? Yes it is. But nowadays, no probably not, but you get the point.
Yeah, light emitting diodes don't work like traditional incandescents. I suppose you could say that a filament bulb is a controlled fire, at the most simplistic and basic level, but that's a misrepresentation of what's really happening. The filament heats up to a very high temperature, causing it to glow and emit light. This process is known as incandescence, and it involves heating a material until it emits light, rather than burning or combustion, which would involve a chemical reaction with oxygen to produce fire. The bulb is filled with an inert gas or a vacuum to prevent the filament from burning up due to oxidation.
