What is LED?

Light Emitting Diodes (LED ) are increasing gaining favour in both the domestic and commercial sectors; due to their efficiency, sustainability and durability.  LED are semiconductor devices, which work on the movement of electrons.  This movement of electrons converts the energy supplied to the LED into protons, producing light. This process is called electroluminescence. Depending on the band of energy used by the semiconductor in the device, an LED can be a number of different colours and can be used in a variety of ways, from creating the infra-red beam in your TV remote, to providing white light for illuminating your home.
