light filaments
Light filaments are thin, elongated structures that emit light when an electric current passes through them. They are commonly found in incandescent light bulbs, where a tungsten filament heats up and glows, producing visible light. The process relies on the principle of incandescence, where materials emit light when heated to high temperatures.
In addition to incandescent bulbs, light filaments can also be seen in some types of neon lights and LEDs, where they serve different functions. These filaments can vary in size and shape, contributing to the overall design and efficiency of lighting products.
