Lightemitting diode

En lysdiode (eller LED , fra engelsk light – emitting diode ) er en halvleder-diode som utstråler lys under tilførsel av elektrisk strøm. Strålingen er inkohorent . It is a p–n junction diode that emits light when activated. When a suitable current is applied.

Electronics Tutorial about Light Emitting Diodes or LEDs with LED Types, Colours and the use of Series Resistors to limit current flow. A light Emitting Diode (LED) is an optical semiconductor device that emits light when voltage is applied. Introduction: The LED is a light source which uses semiconductors and electroluminescence to create light.

A light – emitting diode ( LED ) is a semiconductor device that emits visible light when an electric current passes through it. There are two major kinds of light emitting diodes : .

But, even better, there are LEDs ( light – emitting diodes ) that are just as bright as bulbs, last virtually forever, and use hardly any energy at all. We have covered working principle of Light Emitting Diode or LED. A Light Emitting Diode is a semiconductor device that produces monochromatic incoherent light. The device consists of a p-n junction with a forward . Most LEDs are made from a semi-conducting material called . The increasing demand for light emitting diodes (LEDs) has been driven by a number of application categories, including display backlighting, communications , . LED , in full light – emitting diode , in electronics, a semiconductor device that emits infrared or visible light when charged with an electric current.
