Etymology

The word "LED" is an acronym for "Light Emitting Diode". It is a semiconductor device that emits light when current flows through it.

The word "LED" was first used in the 1960s. It is a combination of the words "light" and "diode".

The word "diode" comes from the Greek word "diōdēs", which means "two-way". This is because a diode is a device that allows current to flow in one direction only.

The word "light" comes from the Old English word "leoht", which also means "light".

So, the word "LED" literally means "light-emitting diode".
