Introduction to 12V IR LEDs

12V IR LEDs are a type of semiconductor device that emits infrared light when an electric current is applied. These LEDs are designed to operate at a voltage of 12 volts, making them suitable for a wide range of applications. The infrared light emitted by these LEDs is invisible to the human eye, which makes them ideal for applications where light visibility is not desired or required.

Working Principles of 12V IR LEDs

The working principle of a 12V IR LED is based on the semiconductor junction. When an electric current is applied to the junction, electrons and holes are excited, and energy is released in the form of photons. In the case of IR LEDs, these photons are in the infrared spectrum, which is outside the visible range of human eyes. The intensity of the emitted light depends on the material of the LED and the current flowing through it.
