How Does Polychromatic LED Technology Work?

Light is an essential nutrient of life. Using the sun’s light as therapy dates back thousands of years. Modern science has evolved the engineered delivery of the beneficial wavelengths (colors) of the sun’s light into low-level light therapy (LLLT) technology.

Thirty years (and counting) in the manufacturing of LLLT devices, InLight Medical products are the state-of-the-art outcome of this evolution uniquely designed as polychromatic light emitting diodes technology (PLT) with Progressive Multi-Pulse™ delivery. Polychromatic light therapy is a unique therapy that harnesses the powers of near-infrared light. Unlike normal blue, red or yellow light, near-infrared (also known as NIR) light is invisible to the human eye. It emits special wavelengths of light energy that dramatically increase circulation to areas of chronic pain. The NIR light has been reported to dilate blood vessels at the site of treatment. The result tends to be a more rapid relief of discomfort, improvement in sensation, and regeneration of damaged tissues.

InLight’s proprietary Progressive Multi-Pulse™ technology delivers different wavelengths of light in varied pulsed rates. Legally marketed as an FDA Class II Medical Device, it is confirmed that the application of InLight’s flexible neoprene therapy pads laden with polychromatic LED combinations of red, blue, and near-infrared diodes directly onto the skin introduces the benefits directly to the body parts through skin response.

“Photobiomodulation” (PBM) is the newly established (2016) Medical Science Heading (MeSH keyword) used by the National Institute of Health published research database to describe this emerging science.  “PHOTO” means light. “BIO” means living tissue. “MODULATION” means change. PLT initiates the photobiomodulation process which releases nitric oxide – gently increasing circulation (blood flow) throughout the body delivering vital nutrients.  Evidence demonstrates photobiomodulation signals damaged cells to begin their repair processes.  This mechanism of action is a photo-chemical response, not a heat/thermal response, therefore the tissue is safe from thermal damage making the InLight Medical systems both safe and effective for home use.

Light energy is not only essential to life, it provides powerful support to the body’s natural healing processes. Polychromatic LED light energy, delivered via light emitting diodes at various wavelengths, penetrates tissue at different depths, and is naturally absorbed by the cells to assist in the production of ATP (adenosine triphosphate), energy required for cell repair and regeneration. PLT energy application also facilitates the release of nitric oxide supporting the body with improved circulation. Improved circulation (blood flow) is one of the most vital components of the healing process. LED light energy is a valuable tool to utilize for health, wellness and vitality.
