Introduction to Near Infrared LED Industry

What is Near Infrared LED?

Near Infrared LED (Light Emitting Diode) is a type of semiconductor device that emits light in the near infrared spectrum, which is the region of the electromagnetic spectrum between visible light and microwaves. These LEDs have a wavelength range of approximately 700 to 1500 nanometers, making them invisible to the human eye. Near infrared LEDs are widely used in various applications due to their unique properties and benefits.

How Does Near Infrared LED Work?

Near infrared LEDs work on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The semiconductor material used in near infrared LEDs is typically gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). When an electric current is applied, electrons and holes recombine in the semiconductor material, releasing energy in the form of photons. These photons fall within the near infrared spectrum, making the light invisible to the human eye.
