Semiconductor devices called near-infrared emitting diodes (NIREDs) emit light in the near-infrared region of the electromagnetic spectrum, typically at wavelengths between 700 and 2500 nanometers (nm). Because they can generate light in the near-infrared spectrum, NIR LEDs are a subset of light-emitting diodes (LEDs) that are employed in a variety of applications.
The electromagnetic spectrum’s region immediately beyond the visible light spectrum is called the near-infrared, and NIR LEDs emit light in this region. When invisible illumination is required, this region is frequently used in applications.
In remote sensing, for example, NIR LEDs are used to illuminate cameras and sensors so they can record data or images in dimly lit areas or in situations with restricted sight of the visible spectrum.
The Global Near-infra-red emitting diodes(NIR LED) market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Near-infrared (NIR) light-emitting diodes (LEDs) have been developing quickly due to its high potential for use in bio-imaging and clinical diagnosis, night-vision devices, fibre-optic communications, and computing.
Light affects plant growth primarily in two ways: it contributes to photosynthesis as energy to encourage the accumulation of plant energy; and it acts as a signal to encourage the accumulation of phytonutrients and to control a plant’s growth and development, including germination, flowering, and stem growth.
Chlorophylls A and B, phytochromes Pr and Pfr, and NIR light all respond strongly to infrared radiation. In order to stimulate plant development, LED light sources are currently employed extensively in plant factories for interplant irradiation.
Wearable NIR LED-equipped food/medical testing equipment can be used in a variety of settings, including home care, driving tests, and training for sports. An NIR light source with a broad emission spectrum is typically required in new applications like food testing and health monitoring because organic constituents in food and human organs have a wide range of absorption and reflection spectra.
The ability to emit light with a wide range of wavelengths is the most crucial feature of light sources for NIR spectroscopy in this context. The number of items that can be analysed increases as NIR light’s wavelength range does.
