Introduction to 12V LED Diode

A 12V LED diode is a semiconductor device that emits light when an electric current passes through it. It operates at a voltage of 12 volts, making it suitable for various applications that require a stable and reliable light source. The 12V LED diode is widely used in automotive, household, and industrial applications due to its compact size, low power consumption, and long lifespan.

Working Principle of 12V LED Diode

The working principle of a 12V LED diode is based on the semiconductor material, typically gallium nitride (GaN) or silicon carbide (SiC), which emits light when an electric current passes through it. When the diode is forward biased, meaning the positive terminal of the voltage source is connected to the anode (longer lead) and the negative terminal is connected to the cathode (shorter lead), electrons and holes recombine at the junction, releasing energy in the form of light. The color of the light emitted by a 12V LED diode depends on the semiconductor material used. Common colors include red, green, blue, yellow, and white. The color temperature of the light can vary from warm white to cool white, depending on the application requirements.
