Hõõgniidiga

Hõõgniidiga, often translated as "incandescent filament," refers to the thin wire within an incandescent light bulb that produces light when heated by an electric current. This filament is typically made of tungsten due to its high melting point and durability. When electricity passes through the filament, its resistance causes it to heat up to a very high temperature, making it glow and emit light. This process is known as incandescence. The filament is enclosed in a glass bulb, which is usually filled with an inert gas or a vacuum to prevent the filament from oxidizing and burning out quickly. The thinness of the filament is crucial for achieving the necessary resistance and temperature for light production. Over time, as the filament heats and cools repeatedly, small amounts of tungsten evaporate, causing the filament to thin further and eventually break, leading to the bulb's failure. This design was the basis of early electric lighting and has largely been superseded by more energy-efficient technologies like LEDs and fluorescent lamps.
