Light Bulb How Does It Work at Loyd Martin blog

Light Bulb How Does It Work. As the current travels through the wires and the. And when the filament heats up, “incandescence” is created, which is light produced by heat. At the most basic level, light bulbs work by exciting atoms that release photons of light. Light bulbs have been around for quite a while now, but you may not know that they work on complex principles of electrodynamics. Basically, an incandescent light bulb is a controlled fire on display. When a light bulb connects to an electrical power supply, an electrical current flows from one metal contact to the other. When electrical current makes contact with the base of the bulb, electricity enters and heats the tungsten filament housed inside. The light bulb works by heating a filament inside a glass enclosure. Different materials have been used for the filament over the years. Not all photons emit visible light , however. Tungsten has a high melting point and can be heated to high temperatures without blackening the glass. In fact, most of the radiation is emitted as heat rather than visible light. The heat from the filament produces light.
