Morphology

LED = light + emit + diode (opaque) = L + E + D

The headword is an initialism of 'light‑emitting diode'; the letters themselves do not transparently convey meaning to learners unless they know the expanded phrase.

Etymology

LED stands for light-emitting diode. The emit part means 'send out' and the diode part is like a 'one-way gate' for electricity, so an LED is a tiny device that 'sends out' light when electric current goes through it, which is why LED now names small, energy-saving lights.
