Fire

When we supply energy (activation energy) to a flammable gas, like methane, it burns. A chemical reaction occurs in which atoms rearrange, bonds made and broken. And energy is released. In the form of heat and light. But what is fire, actually? This may be a stupid question, but is this some sort of source of the photons of light? Like, the burning gas's electrons rearranging to give out EM waves in the area of the 'fire'? Light energy doesn't emanate from a filament lamp in the form of 'fire', does it?
