Introduction To LEDs
Dec 07, 2018

     Light-emitting diodes are simply referred to as LEDs. It is made of a compound containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), or the like.

     When electrons and holes recombine, they can radiate visible light, and thus can be used to make light-emitting diodes. Used as an indicator light in circuits and instruments, or as a text or digital display. The gallium arsenide diode emits red light, the gallium phosphide diode emits green light, the silicon carbide diode emits yellow light, and the gallium nitride diode emits blue light. Organic light-emitting diodes OLED and inorganic light-emitting diode LEDs are further classified by chemical properties.
