Before entering the discussion in this field, some people may ask: What is healthy lighting? What kind of impact does healthy lighting have on us? What kind of light environment is needed by people? Studies have shown that light affects humans, not only It only affects the direct visual sensory system, and it also affects other non-visual sensory systems.
Biological mechanism: the effect of light on people
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. Melatonin affects the internal biological laws of the body, including circadian, seasonal and annual rhythms to adapt Changes in the outside world.Professor Jeffrey C. Hall from the University of Maine, Professor Michael Rosbash from Brandeis University, and Professor Michael Young from Rockefeller University won the Nobel Prize in Medicine for their discovery of circadian rhythm and its causal relationship with health.
Melatonin was first extracted from cattle pine cones by Lerner et al. in 1958, and it was named as Melatonin, which is a neurological endocrine hormone. Under normal physiological conditions, the secretion of melatonin in the human body is more nights and less days, showing circadian rhythmic fluctuations. The greater the light intensity, the shorter the time required to inhibit the secretion of melatonin, so middle-aged and elderly people The group prefers light demand with a warm and comfortable color temperature, which promotes the secretion of melatonin and improves sleep quality.
From the perspective of the development of medical research, it only acts on the pineal gland through non-visual information pathways, which affects the secretion of human hormones, thereby affecting human emotions. The most obvious effect of lighting on human physiology and psychology is to inhibit the secretion of melatonin and improve the quality of sleep. In modern social life, a healthy artificial light environment can not only meet lighting needs, reduce glare, but also regulate human physiology and mental emotions.
Feedback from some users or related research can also prove that light has an impact on the human body. Cai Jianqi, director and researcher of the Visual Health and Safety Protection Laboratory of the China National Institute of Standardization, led a team to conduct research cases on the primary and secondary school student groups for reference. Two case results All are: adopting a systematic solution of "scientific fitting-healthy lighting-visual function detection and tracking and supporting guidance" is expected to achieve myopia prevention and control, and healthy light has a positive impact on the human body. Therefore, adequate outdoor natural light exposure is beneficial to the human body. About two hours of outdoor activities a day can effectively reduce the risk of myopia, improve the quality of life and strengthen the ability to control negative emotions. On the contrary, the lack of a certain amount of natural light, insufficient lighting, uneven light, glare, and stroboscopic light environment have caused more and more students to be troubled by eye diseases such as myopia and astigmatism, and even affect psychology and produce negative emotions. , Irritable and restless.
User needs: from bright enough to healthy lighting
Most people don’t know what kind of lighting environment they need to build for healthy lighting in terms of the needs of the light environment. Similar concepts such as "bright enough = healthy lighting" and "natural light = healthy lighting" still exist in many people's minds. , The needs of such users for the light environment can only satisfy the lighting use.
These needs are reflected in the user's choice of LED lighting products. Most users will prioritize appearance, quality (durability and light decay), and the ability to adjust color temperature. The brand's popularity ranks fourth.
The needs of students for the light environment are often more clear and specific: they tend to have a higher color temperature, inhibit the secretion of melatonin, and make the learning state more awake and stable; there is no glare and strobe, and the eyes are not easy to fatigue in a short period of time.
But with the improvement of people's living standards, in addition to being sufficiently bright, people began to pursue a healthier and more comfortable light environment. At present, there is an urgent need for healthy lighting in places with a high degree of health concern, such as major schools (in the field of education lighting), office buildings (in the field of office lighting), and home bedrooms and desks (in the field of home lighting). The application fields and the needs of the people are greater.
Cai Jianqi, director and researcher of the Visual Health and Safety Protection Laboratory of the China National Institute of Standardization, believes: "Health lighting will first be expanded from the field of classroom lighting, and will gradually spread in fields including elderly care, office and home furnishings." There are 520,000 classrooms, more than 3.3 million classrooms, and more than 200 million students. However, the light sources used in the classrooms and the lighting environment are uneven. This is a very large market. The demand for healthy lighting makes these fields have great market value.
From the perspective of the scale of classroom renovation across the country, ShineOn has always paid attention to the development of healthy lighting, and has successively launched healthy lighting and full-spectrum series of LED devices. At present, it has developed a rich series and complete products, which can provide customers with rich and diverse needs of healthy light products to meet Huge market transformation needs.
The light source is combined with the living environment to meet the needs of users
As the next outlet of the industry, health lighting has become a consensus from all walks of life. Domestic health lighting LED brands have also spotted the demand potential of the health lighting market, and major brand companies are rushing to enter.
Therefore, according to different people’s needs for healthy light, the light source produced through advanced R&D technology is combined with the human settlement environment to carry out scientific and meticulous scene division, through intelligent control methods, to provide a reasonable healthy light environment, and the light source is combined with the human settlement environment. , Is the future development direction.
Professor Wang Yousheng, vice chairman and secretary-general of the Guangdong-Hong Kong-Macao Vision Health Innovation Consortium, proposed that the most ideal and healthy light environment should have sufficient brightness in illumination, without flicker, and close to the spectrum of natural light. But whether such a light source can be suitable for all the light source requirements of the living environment. The needs of the living environment are different, the user groups are different, and the health of the lighting should not be generalized. The light of different times, seasons, and scenes affects the rhythm of day and night, and also affects the psychology and physiology of the human body. The dynamics of natural light affects the self-regulation ability of the eye pupils of the human visual system. The light source must be combined with the living environment. Opportunity to create a healthy lighting environment.
The ShineOn full-spectrum Ra98 Kaleidolite series health lighting LED, which is currently highly regarded in the market, can be used with application manufacturers for different activity scenarios, such as classrooms, study rooms and other specific places. The spectrum can be appropriately adjusted to protect the eyes of young people and improve visual comfort It allows people to stay in a comfortable and healthy light environment, protect eyesight, and improve the quality of work, study and life.
