Description

Integrated LED Light Source for Photobiological Regulation and Its Fabrication Method Technical Field

[0001] This invention relates to the field of LED technology, and in particular to an integrated LED light source for photobiological regulation and its preparation method. Background Technology

[0002] Photobiological regulation refers to the metabolic and cellular responses of living cells to photons, or "light energy." This includes electromagnetic radiation (EMR) in the visible spectrum, as well as the near-infrared (NIR) and ultraviolet (UV) bands.

[0003] Photobiological regulation occurs in all living organisms. It happens naturally in cells exposed to sunlight, but also in specific wavelengths (colors) of artificially produced light. It is present 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] Currently, the mainstream photobiological regulation methods mainly include the following three approaches:
