The number of photons and the energy of each photon control the brightness and color of light. NIR light therapy employs directed low-power but high-fluency monochromatic or quasi monochromatic light from lasers or light-emitting diodes (LEDs) at wavelengths ranging from red to near-infrared to mediate biological activities or promote therapeutic effects in a safe manner.
NIR and LED light can activate photoreceptor cytochrome c oxidase, resulting in enhanced energy metabolism, wound healing, and toxicity inhibition. NIR light is used to transform luminous energy into metabolic energy in order to change the biological processes of cells. In comparison to the impacts of high-energy photons produced by lasers, which cause heating and death of biological tissues and cells.
Furthermore, low irradiances are frequently focused at the tissue, which has no side effects since the energy given by NIR light is low enough not to induce heating and tissue death but high enough to mediate cell and tissue processes. Photodynamic treatment, for example, has been employed without side effects in skin condition applications, and electrical photo neuromodulation in neurons may be produced without thermal consequences.
In clinical practice, the therapeutic optical window corresponding to red to near-infrared wavelengths corresponds to the luminous energy that stimulates stimulation of sensitive intracellular molecules in vivo. That is why NIR light is referred to as near-infrared light treatment, which is based on the premise that specific molecules in living cells and tissues absorb photons, triggering signaling pathways.
This causes energy conversion, in which specific molecules are energized by light and achieve an electrically excited state, changing their shape and activity and activating signaling pathways that govern cellular metabolism. In contrast to traditional high intensity lasers, no damaging effects such as massive heating, tissue damage through ablation, coagulation, dissection, or evaporation occur.
Solar energy from sunlight is the principal source of electromagnetic radiation on Earth. Solar energy encompasses many electromagnetic waves, such as wavelengths in the visible spectrum, which are multidirectional and not synchronized in time and space. NIR light, on the other hand, is monochromatic, allowing for excellent selectivity in molecular biomodulation.
NIR light may be obtained by LED arrays and lasers used in PBM of eyes. Lasers may provide efficient coherent light energy that allows for great tissue penetration, and this consistent beam delivers energy to defined locations. Laser beam width may be increased by linking them with fiber optics, allowing energy to be distributed to wider regions.
The Global NIR LED Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Ever light Electronics CO. LTD., a global leader in the LED and optoelectronics industries, introduces the NIR-C19M series with a wavelength, which provides the best contrast for reading the iris pattern. The identification process is exact, rapid, and efficient in terms of heat dissipation. As a result, it is ideal for iris recognition applications in security surveillance systems (access control) and mobile phones.
The notion of body access code has been implemented into various systems and gadgets as a consequence of market demand and the subsequent development of relevant high technology. Smart biometric identification swiftly and simply measures users unique patterns in the fingerprint, voice, iris, and face to circumvent the challenge of remembering traditional lengthy passwords.
Infrared LEDs for non-contact optical identification offer the benefits of small size, high security, and fast recognition speed, making them a highly sought-after sophisticated technology all over the world.
The NIR-C19M series from Ever light uses a molding manufacturing method for non-contact optical iris identification. Molding produces a smoother surface than the usual glue dispense production procedure, which not only improves the aesthetic but also boosts dependability.
The NIR-C19M series employs a wavelength and an advanced ISP image processor in conjunction with a CMOS sensor to detect infrared reflection from the human eye in order to confirm iris identification. Heat dissipation combined with thermal resistance outperforms any other competing product on the market.
The gadget has also passed IEC62471, a safety standard that ensures no harm is done to human eyes or skin. In addition to these outstanding optical characteristics, the NIR-C19M series has a compact size that is ideal for space-constrained portable devices.
Ever light unites its skilled R&D, Sales, and Marketing teams to drive continuous innovation and technical breakthroughs, allowing it to supply clients with the most complete and high-quality LED-related solutions.
