Introduction to Near Infrared LED Industry
What is Near Infrared LED?
Near Infrared LED, short for near-infrared light-emitting diode, is a type of semiconductor device that emits light in the near-infrared spectrum. The near-infrared region is the part of the electromagnetic spectrum between visible light and microwaves, with wavelengths ranging from 700 to 3000 nanometers. Near Infrared LEDs are widely used in various applications due to their unique properties, such as high brightness, long lifespan, and low power consumption.
Working Principle of Near Infrared LED
The working principle of Near Infrared LED is based on the photoelectric effect. When a semiconductor material, such as gallium arsenide (GaAs) or indium gallium arsenide (InGaAs), is excited by an external electrical current, electrons are released from the valence band to the conduction band. As the electrons move from the conduction band to the valence band, they release energy in the form of photons, which have a wavelength within the near-infrared range.
The key to producing a near-infrared LED lies in the composition of the semiconductor material and the design of the device structure. By carefully selecting the material composition and adjusting the thickness of the layers, engineers can control the emission wavelength of the LED.
