What does LED stand for in lighting technology?

LED stands for Light Emitting Diode. This terminology is crucial in understanding how LED lighting technology operates. LEDs work by converting electrical energy directly into light through a process called electroluminescence, where electrons recombine with electron holes within the device, releasing energy in the form of photons. This process makes LED lighting highly efficient, longer-lasting, and environmentally friendly compared to traditional lighting methods such as incandescent or fluorescent bulbs.

The other options do not accurately reflect the function or technology behind LED. Understanding the correct terminology is essential for anyone in the electrical and lighting industries, as it influences choices in design, efficiency, and the overall effectiveness of lighting solutions.
