How Do LED Lights Work?

'Solid State' lighting is the name given to LED lights because solid matter produces the light, there are no filaments or gases required.

So many people ask the question, 'how do led lights work?', so lets have a look at the workings of LED lighting.

LEDs or Light Emitting Diodes are actually one of the simplest types of semiconductor devices.

A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode that emits light when activated.When voltage is applied to the device, electrons fill in the electron holes in the semiconductor and simultaneously release energy. At the same time the photons (i.e. light), in a process known as electroluminescence.

Tthe color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor. LEDs are normally small (less than 1 mm2) and integrated optical components may be used to shape the radiation pattern. READ MORE................
