This article aims to provide an in-depth introduction to the 12V LED diode industry, covering its history, applications, technology, market trends, and future prospects.

History of 12V LED Diodes

The concept of LED (Light Emitting Diode) dates back to the early 20th century when scientists discovered that when a semiconductor material is forward biased, it emits light. However, it was not until the 1960s that the first practical LED was developed by Nick Holonyak Jr. at General Electric. Since then, LED technology has evolved rapidly, and the 12V LED diode has become a crucial component in various lighting applications.

How 12V LED Diodes Work

A 12V LED diode is a semiconductor device that emits light when an electric current passes through it. It consists of a cathode (negative terminal), an anode (positive terminal), and a semiconductor material, typically gallium arsenide (GaAs), gallium phosphide (GaP), or gallium nitride (GaN). When the diode is forward biased, electrons and holes recombine at the junction, releasing energy in the form of photons.
