Introduction to Infrared Light LEDs

What are Infrared Light LEDs?

Infrared light LEDs, also known as infrared diodes, are a type of semiconductor device that emits infrared light when an electric current passes through it. These LEDs are widely used in various applications due to their compact size, low power consumption, and high efficiency. The infrared light emitted by these LEDs is invisible to the human eye, but it can be detected by special sensors and devices.

Working Principle of Infrared Light LEDs

The working principle of infrared light LEDs is based on the semiconductor material, typically gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). When an electric current is applied to the LED, electrons and holes are injected into the semiconductor material. As these charge carriers recombine, they release energy in the form of photons. The energy of these photons corresponds to the infrared region of the electromagnetic spectrum, which is why the emitted light is in the infrared range.
