Technical Field

[0002] Photobiomodulation is the metabolic and cellular response of living cells to photons of "light energy." Photobiomodulation is the metabolic and cellular response of living cells to photons (i.e., light energy), including electromagnetic radiation (EMR) in the visible spectrum as well as in the near-infrared (NIR) and ultraviolet (UV) bands.

[0003] Photobiomodulation occurs in all living things. It occurs naturally in cells exposed to sunlight, but also at specific wavelengths (colors) of artificially produced light. It is found in plants, animals, and bacteria. It stimulates growth, provides energy for cellular respiration and reproduction, stimulates DNA repair, and confers molecular maintenance capabilities to cells, tissues, and organs. In complex organisms, including primates and humans, it is involved in the growth and management of the nervous system, controls blood flow in the circulatory system, stimulates immune responses, and influences stem cell development.

[0004] The current mainstream photobiomodulation methods mainly include the following three methods:
