DIP LED diode, also known as dual in-line package LED diode, is a widely used semiconductor device in the field of optoelectronics. As a key component of LED lighting, DIP LED diodes have been playing an increasingly important role in the lighting industry. This article will introduce the basic concept, characteristics, application fields, and market trends of DIP LED diodes, aiming to provide a comprehensive understanding of this product.

Basic Concept of DIP LED Diode

A DIP LED diode is a semiconductor device that emits light when an electric current passes through it. It is composed of a semiconductor material, a p-n junction, and a metal lead frame. The semiconductor material is usually gallium nitride (GaN), gallium phosphide (GaP), or silicon carbide (SiC). The p-n junction is formed by diffusing impurities into the semiconductor material, creating a potential barrier. When an electric current is applied, electrons and holes are separated at the p-n junction, releasing energy in the form of light.
