What is LED (Light Emitting Diode)?
A LED is a p-n junction diode that is capable of emitting light. An LED operates just like a regular p-n junction diode. Diodes must be forward biased for current conduction.
What differentiates an LED from a regular diode is the semiconductor material used to form the p-n junction - regular diodes are made of semiconductor […]
