Revolutionizing Infrared Technology: Unveiling the Advancements of 940nm Infrared LED

940nm infrared LED, also known as a near-infrared LED, is a type of light-emitting diode that emits light at a wavelength of 940 nanometers. This specific wavelength falls within the near-infrared spectrum, which is just beyond the visible light range. In recent years, the demand for 940nm infrared LEDs has been on the rise due to their numerous applications in various industries. This article aims to provide an in-depth introduction to the 940nm infrared LED industry, covering its technology, applications, market trends, and future prospects.

Technology of 940nm Infrared LED

The 940nm infrared LED is a semiconductor device that emits light when an electric current passes through it. The key components of a 940nm infrared LED include a p-n junction, a semiconductor material, and a lens. The semiconductor material used in 940nm infrared LEDs is typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs), which can emit light at the desired wavelength.

The p-n junction is formed by doping the semiconductor material with impurities to create a region with an excess of electrons (n-type) and a region with an excess of holes (p-type). When an electric current is applied, electrons from the n-type region move towards the p-type region, recombining with holes and emitting light in the process. The lens is used to focus the emitted light into a narrow beam, improving the efficiency and directivity of the LED.
