Izzólámpákét

Izzólámpákét is a Hungarian term that translates to "incandescent lamp" or "light bulb." It refers to an electric lamp that produces light by passing an electric current through a thin filament, typically made of tungsten, which heats up and glows. This process of incandescence is the defining characteristic of this type of lighting technology.

Invented in the late 19th century, the incandescent lamp revolutionized illumination, replacing older methods like gas lamps and candles. Its widespread adoption led to significant advancements in urban development and daily life, allowing for extended working hours and increased safety after dark. Early pioneers in its development include Thomas Edison and Joseph Swan, who independently and collaboratively worked on creating practical and commercially viable designs.

While historically significant and once the dominant form of electric lighting, incandescent lamps are now largely being phased out in many parts of the world due to their inefficiency. They convert only a small fraction of the electrical energy they consume into visible light, with the majority lost as heat. This contrasts with more modern lighting technologies like fluorescent and LED lamps, which offer significantly higher energy efficiency and longer lifespans. Despite their declining use, understanding the principles of izzólámpákét is fundamental to the history of lighting technology.
