LEDs for Photobiomodulation
LumeDEL’s fiber-coupled LEDs deliver stable, targeted light at specific wavelengths, making them ideal for advancing photobiomodulation research and therapeutic applications.
Photobiomodulation
Red and near-IR light (600-1000 nm) are being explored for their potential to address a variety of medical conditions by altering function at a cellular level. Known as photobiomodulation, the technique is under investigation for wound treatment, tissue repair, pain management, treatment of traumatic brain injury, and more. Although some results are promising, possible mechanisms are still subject to debate and the majority of studies focus on animal models or in vitro samples.
Intravenous blood irradiation is another low-level light treatment modality. It has a long history of use on multiple conditions.
Much more research and rigorous clinical trials need to be conducted to establish a solid scientific foundation – and that is where fiber-coupled LEDs come into play.
Early work used laser light sources, but the power levels have the potential to cause tissue damage. The focus has shifted to LEDs. Red and near-IR fiber-coupled LEDs provide highly configurable narrowband output can equip investigators to conduct well-controlled studies to determine which parameters will provide repeatable results.
The NewDEL™ Advantage for Photobiomodulation:
- High radiant power and pulsed modes of operation
- Easy control of parameters like pulse width
Why LEDs for Photobiomodulation?
Photobiomodulation depends on precise delivery of red and near-infrared light to stimulate cellular activity, enhance healing, and reduce inflammation. LumeDEL’s NewDEL™ fiber-coupled LEDs provide stable, high-radiant power output at therapeutic wavelengths, ensuring accurate dosing and reproducible results in both research and clinical applications.
