Introduction to IR Infrared LED Industry

What is an IR Infrared LED?

An IR infrared LED, or infrared light-emitting diode, is a type of semiconductor device that emits infrared light when an electric current is applied. These LEDs are widely used in various applications due to their compact size, low power consumption, and efficient light emission. The infrared spectrum is a part of the electromagnetic spectrum that is not visible to the human eye, but can be detected by specialized sensors and cameras.

How Does an IR Infrared LED Work?

IR infrared LEDs operate on the principle of semiconductor junctions. When an electric current is passed through the diode, electrons recombine with electron holes, releasing energy in the form of photons. In the case of IR LEDs, these photons fall within the infrared spectrum, which ranges from 700 nanometers to 1 millimeter in wavelength. The specific wavelength of the emitted light can be tailored by choosing the appropriate semiconductor materials and designing the LED structure.
