A Light-Emitting Diode (LED) is a solid-state light-emitting element made of a semiconductor material. The principle of illumination of a light-emitting diode is the direct conversion of electrical energy into light energy. First, a group V element such as an element such as nitrogen (N), phosphorus (P), or arsenic (As) and a group III element such as aluminum (Al), gallium (Ga), or indium (In) are passed through a liquid. Phase- Epitaxial Process (LPE) or Vapor Phase Epitaxy (VPE) process to form III-V compound semiconductors, such as gallium phosphide (GaP) or arsenic Gallium (GaAs) is used as a substrate, and then a voltage is applied to the positive and negative electrodes of the substrate.
