1 photosynthesis
Photosynthesis usually refers to the process that green plants (including algae) absorb light energy, synthesize carbon dioxide and water into high-energy organic matter, and release oxygen at the same time.
It mainly includes two stages: light reaction and dark reaction, involving light absorption, electron transfer, photosynthetic phosphorylation, carbon assimilation and other important reaction steps, which is of great significance to realize natural energy conversion and maintain the balance of carbon and oxygen in the atmosphere.
Step 2 reflect
Reflex refers to the regular response of the body to internal or external stimuli. It can be divided into congenital reflex and acquired reflex, which are usually called unconditioned reflex and conditioned reflex. As early as the middle of17th century, Descartes, a French scholar, observed that mechanical stimulation of cornea could cause regular blink response and put forward the concept of reflection.
3. The role of phototherapy
Phototherapy is a kind of physical therapy that uses the radiant energy of light to treat diseases. Phototherapy mainly includes ultraviolet therapy, visible light therapy, infrared therapy and laser therapy.
4. Disinfection effect of lighting
Ultraviolet sterilization means that the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in microbial cells can be destroyed by ultraviolet with appropriate wavelength, resulting in the death of growing cells and/or regenerative cells, thus achieving the effect of sterilization and disinfection.
Ultraviolet disinfection technology is based on modern epidemic prevention, medicine and photodynamic therapy. It uses specially designed UVC band ultraviolet light to irradiate tap water with high efficiency, high intensity and long life, and directly kills various pathogens such as bacteria, viruses, parasites and algae in water.
5. The beauty of light.
Photonic cosmetology is a non-invasive broad-spectrum photodynamic therapy. Can simultaneously treat and improve facial diseases such as facial flushing, rosacea, acne, scars, pigmented spots and freckles, and skin aging diseases such as large pores, wrinkles and elastic tissue degeneration. It can also remove hair, remove spots, remove red blood, tighten skin and lose weight accurately.
Its characteristics are no damage to skin and simple treatment process. You can wash your face and make up immediately after treatment without affecting your normal work. It is an ideal and scientific beauty method at present.
