At present, when people in the lighting industry talk about healthy light,their initial understanding is still from the perspective of stroboscopic, glare, lighting design and so on, and more understanding is from the perspective of full spectrum.
At present, when people in the lighting industry talk about healthy light,their initial understanding is still from the perspective of stroboscopic, glare, lighting design and so on, and more understanding is from the perspective of full spectrum. In fact, the lighting industry basically lacks in-depth research on the different spectral bands of LED light sources. After years of hard work and popularization, we have found that the future transformation and upgrading direction of the lighting industry is healthy light has gradually become the consensus of people inside and outside the industry!
The development of the lighting industry has always been based on visible light. From incandescent light bulbs to energy-saving lamps to LED light sources, visible light is the focus of the lighting industry. However, we all know that in addition to visible light, there is also a large amount of invisible light, such as infrared rays, ultraviolet rays, etc. These invisible lights are actually an important part of light, accounting for more than 70%, which is much higher than the 30% of visible light.
The advancement of LED technology has brought newer and better light sources to mankind. Through LED technology, we can not only get a richer and fuller spectrum, which is closer to the sunlight spectrum, but also the color rendering is closer to sunlight, allowing our lighting quality to be better reflected. The healthy lighting emphasized by the lighting industry is lighting with sunlight as the reference object. The difference is that some call it sunlight, some call it natural light, and some call it natural light. In front of these reference objects, artificial LED light sources use various control methods to set up reasonable strobes, reduce glare, improve color rendering, enrich the light source spectrum to the full spectrum, and even consciously adjust the blue light spectrum components and increase the red light spectrum components. Through these technical adjustments, some lighting fixtures based on high-quality LED light sources have become what we often call healthy lighting.
Healthy light is a new industry covering a larger scope and more fields including healthy lighting, including healthy visible light and the application of invisible light to human health, such as healthy light care, light medical treatment, etc.
Light also has an important impact on human eyes. The eyes are the most important sensory organ, and 82% of the information from the outside world comes from the eyes. According to scientific data, one of the important causes of myopia is the incomplete spectrum. It can be seen that it is important to add a complete spectrum to the light.
Light has an important impact on human immunity and directly affects the level of immunity. Immunity is the body's own defense mechanism and its ability to resist the development of disease. For example, according to professional health big data, 70% of Chinese people are at risk of death from overwork, 76% of white-collar workers are in sub-health, 20% of Chinese people suffer from chronic diseases, and 22% of the causes of middle-aged death are cardiovascular and cerebrovascular diseases. These health problems are closely related to the decline of human immunity! An important factor in the decline of immunity is the reduction of human outdoor activities and the reduction of time to enjoy the sun, resulting in a lack of light energy and nutrient absorption.
Light has an important impact on human body mood and directly affects the onset and relief of depression. Depression is a serious psychological disorder that may have an impact on the patient's physical and mental health, ranging from low mood at the beginning to attempted suicide. According to previous surveys by the World Health Organization, about 350 million people worldwide suffer from depression. The incidence rate is 6.16% in Sweden, 4.45% in the United States, and 3.02% in China. There are about 30-45 million people with depression in my country. Not optimistic! Depression is naturally related to the lack of appropriate light. In places with abundant sunlight, depression is rare; in places with insufficient sunlight, depression is common. Therefore, light has a very good preventive and therapeutic effect on depression.
However, the current application of LED light sources in invisible light such as ultraviolet and infrared fields is still limited, and there is still huge potential to be tapped and developed. This is also the huge development space for the light health industry as a trillion-dollar industry. In these fields, scientists around the world are working hard to explore and constantly introduce the latest scientific research results and applications.
Therefore, lighting has been upgraded to healthy lighting. Both are based on the application of LED light sources. Healthy light focuses more on the comprehensive application of LED light sources, including visible and invisible light parts; lighting focuses more on the application of the visible light part of LED light sources.
Lighting upgrades to improve healthy light can also bring huge economic benefits to the society and industry. Cosio Lighting will try our best to contribute to healthy lighting.
