LED

by V3.co.uk staff

04 Mar 2011

A light-emitting diode (LED) is a solid-state light source based on a small semiconductor chip encased in plastic.

LEDs have a number of applications in computing, from simple coloured indicators in keyboards and other devices, to backlights illuminating flat-panel screens, to LED lasers seen in DVD drives and fibre-optic communications.

Advantages of LEDs over incandescent light sources include lower energy consumption, longer lifetime, robustness, smaller size, faster switching, and greater durability and reliability.
