What is the healthy white full spectrum LED means?
Scientific research has found that light is one of the main driving forces of the human body's circadian rhythm system. Whether it is natural sunlight or artificial light sources, it will trigger a series of circadian rhythm responses. Light affects human health to varying degrees through visual and non-visual effects. Therefore, it is of great practical significance to advocate "White full spectrum healthy lighting" and improve light quality and comfort.
The so-called White full spectrum healthy lighting is to improve and enhance people's working, studying, and living conditions and quality through lighting, and to promote mental and physical health.
The solar spectrum is the healthiest spectrum. The solar spectrum mainly includes ultraviolet, visible and infrared spectra. Ultraviolet light has the effect of sterilization and disinfection. It can kill mites and other microorganisms or pathogens, promote the synthesis of vitamin D, prevent and treat rickets and rickets, and prevent osteoporosis in the elderly. It has anti-inflammatory and pain-relieving effects, promotes local blood circulation, and regulates immunity. Infrared rays have a good therapeutic effect on human tissue metabolism, blood circulation, and enhancement of human immune function; at the same time, it has a therapeutic effect on muscle spasm, muscle strain, soft tissue injury, and body tissue swelling.
The so-called White full spectrum healthy lighting mainly means that the artificial light source spectrum used for lighting should be as close as possible to the visible spectrum of the sun (i.e. imitating natural light lighting), and the lighting must meet the functional requirements of the place and the psychological requirements of people. It not only requires the comfort of lighting, but also satisfies people's psychological emotions in terms of color temperature, brightness, and harmony between light and shadow. On the basis of high color rendering index, reduce the relative energy of blue light (R12) to prevent blue light harm; increase the relative energy of red light (R9) to promote the body's physical and mental health.
Blue and UV wavelength problem
According to official statistics, the probability of my country's 7-12, 13-15, and 16-18 year-old students suffering from eye diseases is 45.71%, 74.36%, and 83.28%, respectively. The incidence of eye diseases among adolescents has surpassed Japan to become the world's largest country.
People generally attribute the reasons to two aspects. One is that children are stressed with homework and overuse their eyes; the other is that they are facing electronic products such as mobile phones and tablets for a long time. Two factors cause eye fatigue in adolescents, resulting in decreased eye adjustment ability, which in turn induces eye diseases.
According to a research report issued by the International Commission on Illumination CIE in 2002 (CIE S 009/E:2012): Blue light can cause photochemical damage to the retina, mainly concentrated in the retinal pigment inner epithelial cells, and form arcs and blind spots on the retina. The eye can see things because rod cells and cone cells are distributed on the retina. The axial end of the retina has a place called the fovea. This is the area with the sharpest vision and the most abundant visual cells. It appears yellow because it is rich in lutein. Under normal circumstances, with age, the macular fovea ages and causes visual decline.
However, under long-term exposure to blue light, excessive blue light directly enters the retina and generates a large number of free radicals, which accelerates the oxidation of the macular fovea, and ultimately leads to the death of a large number of visual cells in the macular fovea, and this damage cannot be repaired by itself.
In April 2018, the Institute of Global Health in Barcelona, Spain (ISGlobal) announced that the longer the blue light exposure at night, the more people’s body rhythms will be broken, leading to an increase in the incidence of breast and prostate cancer. The results of this study "assessed the relationship between nighttime exposure to artificial lighting in Spain and the risk of breast and prostate cancer. It must be emphasized that excessive amounts of the spectrum in any band are harmful.
