How LEDs work

Like ordinary diodes, light-emitting diodes consist of a PN junction and also have unidirectional conductivity. When a forward voltage is applied to the light-emitting diode, the holes injected from the P region to the N region and the electrons injected from the N region to the P region are respectively connected with the electrons in the N region and the empty holes in the P region within a few microns near the PN junction.

Introduction to LEDs

Light-emitting diodes are referred to as LEDs for short. Made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), and the like.

What are LEDs?

Light-emitting diodes, abbreviated as LEDs, are commonly used light-emitting devices that emit energy through the recombination of electrons and holes, and are widely used in the field of lighting.
