text: The LED emits light when it is forward biased and it emits no light when it is reverse biased.
text: When Light Emitting Diode (LED) is forward biased, the free electrons from n-side and the holes from p-side are pushed towards the junction.
text: When an LED is forward biased, the bands bend slightly in a way to decrease the energy barrier between the n- and p-type semiconductors.
text: Generally the light resulting from each electron/hole recombination is very directional and short lived, but the millions of recombinations happening when the LED is forward biased produce light continuously.
text: When the LED is forward biased, the free electrons cross the PN junction and recombine with holes.
text: When an external voltage is applied to this circuit, one LED will operate at a time and due to this circuit action, it emits a different light when one LED is forward biased and the other is reverse biased or vice versa.
text: To operate, a LED must have current flowing through it, and this can only happen if it is forward biased.
text: When the light emitting diode is forward biased by applying 2 or 3 volts across its terminals then it emits the visible coloured, invisible infrared or laser light of narrow band width.
text: The light emitting diode emits light when it is forward biased.
