light emitting diode (LED)
Definition
Electronic device that emits light when electric current flows through it. Older LEDs were made from semiconductor material such as gallium arsenide and produced only a few colors (mainly red or green). Newer LEDs are made from synthetic materials such as p-phenylenevinyl and can produce light of any color. LED-based lighting bulbs that consume little current and last for decades are under development.
