Electric light is a form of illumination produced by the flow of electric current through a material. This process typically occurs in devices called light bulbs, which can be incandescent, fluorescent, or LED. When electricity passes through the filament in an incandescent bulb, it heats up and emits light. In fluorescent bulbs, gas is excited by electricity, producing ultraviolet light that then illuminates a phosphor coating inside the bulb. The invention of electric light revolutionized how people live and work, extending productive hours beyond daylight. Pioneers like Thomas Edison played a crucial role in developing practical electric lighting systems. Today, electric light is essential in homes, streets, and workplaces, enhancing safety and convenience.
