This article delves into the world of 12V LED diodes, exploring their features, applications, advantages, and the industry trends surrounding them.

Introduction to 12V LED Diodes

12V LED diodes are electronic components that emit light when an electric current passes through them. They are composed of a semiconductor material, typically gallium nitride (GaN) or silicon carbide (SiC), which emits light when excited by an electric current. The 12V rating refers to the voltage at which the diode operates efficiently and safely.

Working Principle of 12V LED Diodes

The working principle of a 12V LED diode is based on the semiconductor material's ability to emit light when an electric current is applied. When an electric current flows through the diode, the electrons and holes recombine within the semiconductor, releasing energy in the form of photons. The color of the light emitted depends on the semiconductor material used and the energy band gap of the material.
