SUMMARY
Light is produced in light bulbs through the flow of electrons in a tungsten filament, which, when heated due to collisions with atoms, emits light. The process begins when an electric field is applied, causing electrons to flow and collide, generating heat that causes the filament to glow. This glowing filament emits light as a result of oscillating charged particles, releasing photons. The discussion also touches on the role of deep electrons in light emission and their interaction with surrounding atoms, suggesting that while they may contribute to heat, the primary source of visible light is from the filament's surface.
