izzószálas
izzószálas is a Hungarian term that translates to "filament bulb" or "incandescent filament" in English. It refers to the thin wire inside an incandescent light bulb that glows when heated by an electric current. This filament is typically made of tungsten, a material chosen for its high melting point and durability. When electricity passes through the filament, its resistance causes it to heat up to a temperature where it emits visible light. This process, known as incandescence, is the fundamental principle behind traditional light bulbs. The glass bulb surrounding the filament is usually filled with an inert gas or a vacuum to prevent the filament from oxidizing and burning out quickly. While widely used for many decades, incandescent bulbs are becoming less common due to their low energy efficiency compared to newer lighting technologies like LEDs and CFLs. The term izzószálas is therefore associated with older forms of lighting technology.
