This article delves into the world of 12V IR LEDs, exploring their features, applications, and the technological advancements that have made them a staple in numerous industries.

Introduction to 12V IR LED

The 12V IR LED, or Infrared Light Emitting Diode, is a type of diode that emits infrared radiation at a voltage of 12 volts. Unlike visible light, infrared light is not visible to the naked eye, making it ideal for applications where covert lighting is required. These LEDs are widely used due to their high efficiency, low power consumption, and long lifespan.

How 12V IR LEDs Work

12V IR LEDs operate on the principle of electroluminescence, where an electric current is applied to a semiconductor material, causing it to emit light. The semiconductor material used in these LEDs is typically made of gallium arsenide or indium phosphide, which has a direct bandgap that allows for efficient emission of infrared light. When a forward bias voltage is applied to the LED, electrons and holes are injected into the depletion region. As these electrons and holes recombine, they release energy in the form of photons. In the case of 12V IR LEDs, these photons fall within the infrared spectrum, making them invisible to the human eye.
