It has been three years since led health lighting was proposed by the market in 2015. In the past two years, led health lighting is still in its infancy.
With the continuous progress and popularization of technology, more and more manufacturers are involved in health lighting in 2018. In addition to Seoul semiconductor, Philips and other international manufacturers, Chinese manufacturers are also gradually joining the LED health lighting camp, such as the eyelove health lighting series products recently launched by Guoxing Guangdian. In addition, other domestic manufacturers such as Hongli and Ruifeng also launch health lighting related products.
Led health lighting industry has begun to take shape. With the further improvement of technology and the further decline of cost, LED will quickly enter the era of health lighting.
At present, blue light prevention is the main technical direction
Led health lighting refers to that the light emitted by LED lighting products will not cause harm to the human body, especially to the eyes that are in direct contact with the light. However, most of the LED light source products on the market only pursue the effect of "lighting", and focus more on improving the light efficiency and reducing the cost.
For some inferior products, the proportion of short wave blue light is too high, which will lead to visual fatigue and visual loss of users; what's more, short wave blue light will directly penetrate the lens and directly reach the retina, leading to macular disease and cataract, which has a more obvious impact on children in their growth and development period.
Therefore, led health lighting technology, are mainly from the spectrum, to minimize the harmful spectrum to reduce or remove. This is the direct understanding of LED health lighting in the market at present, mainly for anti blue light, anti stroboscopic, or add some adjustable color temperature, adjustable brightness function. But is this led health lighting? Or is led health lighting limited to this? Is there more room for imagination?
Health lighting, not just to remove the harm of blue light
In fact, with the development of lighting science, the relationship between light and health has been found more and more.
For example, lighting has been extended to the field of non visual biological effects. Many studies have shown that the non visual effects of light on human eyes can affect the release of melatonin, sleep and biological rhythm at night through the light perceived by retinal ganglion cells.
In other words, the impact of light on human beings is not only the direct visual sensory system, but also other non visual sensory systems. Light can change the rhythm of life, inhibit the secretion of melatonin, improve the core temperature, speed up the heart rate, improve the alertness and other advantages.
Therefore, led health lighting is not only to reduce the harm of blue light, but also to improve people's working, learning and living conditions and quality, and promote mental and physical health.
Driven by market, technology bottleneck will be broken through continuously
Natural light is the most suitable and comfortable light source for human beings. At present, led health lighting is also imitating natural light to the maximum extent.
Natural light is a full spectrum light source. At present, there are mainly two ways to achieve full spectrum light source in the market, one is the scheme of 450-460nm blue light chip exciting phosphor, the other is the scheme of purple light chip exciting RGB polychromatic phosphor. However, the blue light chip scheme still shows high intensity blue peaks, and the purple light chip scheme is closer to the natural light spectrum. The spectrum of eyelove DL series products launched by Guoxing optoelectronics is very close to the natural spectrum.
No matter which solution, with the increasing attention of human beings to health lighting, driven by the market demand, the technical bottleneck in the field of light will continue to be broken, and the light source more suitable for human lighting will continue to be developed. Perhaps in the future, it is not impossible for human beings to develop light sources that are better than natural light. However, led health lighting is not only for the manufacture of light source, but also for the perfect integration of human real-time environment.
The combination of light source and environment is the future development direction
According to the division of Guoxing optoelectronics, the main seven light environment scenes of human beings are work, leisure, education, catering, sports, bath and sleep.
The future of LED health lighting is to generate the most suitable light source for the current environment according to different environments, and the most suitable light source for the time according to different time points. The same is true of Guoxing Optoelectronics in the direction of LED health lighting. For example, in the field of office lighting, when workers enter the fatigue period, the generation of appropriate light source can improve mood, relieve fatigue, and promote mental and physical health.
Led health lighting is not only for the manufacture of light source, but also includes the research on the relationship between light and human health, which are the direction of future efforts. Focusing on led health lighting, there will be more cross-border, interdisciplinary and interdisciplinary cooperation in the future. The real health lighting is not very far in the future. The LED health lighting series products of Guoxing optoelectronics have been applied in supermarkets and education fields.
Although the current technology is still far away from the ideal led health lighting in the future, with the close cooperation of various disciplines, led health lighting will have great prospects in the future. For LED manufacturers, while developing led health light source technology, they should also pay more attention to the relationship between light and human health.
