Description

Technical Field

[0001] The present invention relates to the field of LED technology, and in particular to an integrated LED light source for photobiomodulation and a preparation method thereof. Background Art

[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:

[0005] The first is to use laser pulse waves for biomodulation, which poses photobiological risks;

[0006] The second is to adjust the multi-band LED monochromatic light chip, which will cause light pollution and cannot guarantee the safety of human eyes;

The blue color is lower than that of sunlight, which is beneficial to eye health and prevents blue light hazards. The crop utilization rate is the same as that of sunlight with the same color temperature, which is beneficial to the growth and development of plants.
