LEDs

When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor.

A rule of thumb with LEDs (Light Emitting Diode) is that they do not like high power, add in a current limiting resistor (Click here for Zeroohm Tutorial) or you will start smelling a smoke!
