what does led stand for

LED stands for "light-emitting diode." A diode is an electronic component that allows current to flow in only one direction, and the "light-emitting" part means this diode lights up when an electric current passes through it. LEDs are semiconductor devices that generate light through a process called electroluminescence. They are used widely because they are energy-efficient, long-lasting, durable, and versatile for various lighting and display applications. In summary, the core meaning of LED is a diode that emits light when powered by electricity. This technology has become the preferred lighting solution due to its efficiency and longevity.
