👉 Lamps, also known as light-emitting diodes (LEDs), are semiconductor devices that convert electrical energy into light through a process called electroluminescence. When an electric current passes through these materials, electrons recombine with electron holes, releasing energy in the form of photons, which we perceive as light. The color of the emitted light depends on the semiconductor material used; for example, gallium nitride (GaN) produces blue or white light, while indium gallium nitride (InGaN) can produce various shades of blue and green. Modern lamps, especially LEDs, are highly efficient, consume less power than traditional incandescent bulbs, and have a significantly longer lifespan, making them an environmentally friendly and cost-effective lighting solution.
