LED medical lighting promising

This is an era in which the mind has opened, and it is an era of pursuing quality. In the era of increasingly strong technological support, people’s attention to quality of life, health and safety has been increasing, and the demand for lighting has become more than a surface layer. To help "see", but pay more attention to the impact of lighting products on people in-depth "invisible", the requirements of lighting is getting higher and higher, and the lighting environment comfort and health also put forward new requirements.

At present, the nation’s increased attention and investment in health care and national health has led to a growing demand for health lighting. With the advancement of technology and the deepening of research, the relationship between light and health is increasingly being It has been found that a series of thematic researches are being carried out or deepened, such as light and non-visual biological effects, light medicine, healthy light environment, etc., and around the healthy lighting, more cross-border and cross-disciplinary and interdisciplinary cooperation has gradually begun.

At the same time, after the LED lighting is produced, it also brings challenges to the original evaluation methods and systems in the lighting field, such as how to evaluate the health and comfort of LED products, and new changes are also occurring. The era of healthy lighting has come.

The prospects for light and health research are promising - promising

The scientific research of lighting continues to deepen, and the relationship between light and health is more and more discovered by humans. For example, lighting has expanded into the field of non-visual biological effects. Many studies have shown that light has no visual effect on human eyes through the retina. The light perceived by the ganglion cells can affect the release, sleep, and biological rhythms of melatonin in the night. Regarding the study of the effects of light color on human physiological parameters, Professor Lin Yandan of Fudan University once stated that the results of the study indicate that light has the potential to change the rhythm of life, suppress the secretion of melatonin, increase the core temperature, accelerate the heart rate, and increase the alertness. . Therefore, its future has broad application prospects, such as the treatment of seasonal affective disorder, the use of red and yellow nightlights to help sleep.

In fact, people-oriented health lighting has been deeply rooted in people's minds. The assessment of color quality, the visual environment, and the influence of lighting on the human rhythm of life and the role of animals and plants have become the focus of scientists' research. This year at the 28th Conference of the International Commission on Illumination (CIE), held at the University of Manchester, UK,

Lighting and human life, color science and quantitative models, measurement and evaluation of lighting scenes, evaluation and measurement of glare, and measurement have become the hottest topics. The light bio-safety of the lamp and lamp system, the blue light problem that is considered to have an impact on human health, glare, and the visual flicker caused by the light source and its system are still the focus of attention in the industry.

At the same time, related measurement, testing, and evaluation studies are also ongoing, such as the visual, health and environmental studies of building windows, the evaluation of the color rendering of light sources, the light bio-safety measurement of light sources, the stray light index evaluation methods for array spectrometers, and light sources. Flicker evaluation, measurement of non-visual effects, testing of the company's vision, influence of visual effects of lighting products on human eyes, etc.

In addition, research on the visual health and comfort of people in the health field for lighting, display, and visualization products is also underway. Cai Jianqi, associate researcher at the China National Institute of Standardization, said that people's health is mainly a light health research to evaluate products against people. The effects of health and safety include circadian rhythm, vision, brain, skin, and psychological cognition to effectively guide the product's design and development in human health. Its R&D characteristics mainly include human health design; objective measurement of product impact on human performance and perception; large sample human factors test data; objective and accurate artificial intelligence evaluation model; It is to improve the safety and health properties of products.

At the same time, he said that the impact of lighting products on people's visual fatigue is also one of the important evaluation factors in the measurement of SSL products. With the advancement of technology, including the development of photometry, colorimetry, optics, ophthalmology, modern medicine and biomedicine, "Visual Human Theory" emerged to effectively evaluate light quality.

From non-visual to visual human factors, cross-disciplinary and cross-border research on health lighting will become a general trend and have a bright future. Healthy lighting will also be a focus of the industry for a long period of time, including this year’s On November 4th, the “Health and Lighting” sub-forum of the 12th China International Seminar on Lighting Industry (SSLCHINA 2015) will be held at the Shenzhen Convention and Exhibition Center. The forum will also focus on healthy light environment, standards, intelligence and product applications. There are problems. From the evaluation of LED product health comfort, health lighting research and standard construction, research on the effect of light environment on human visual function, mechanism research on blue light damage to human eye retina, development status of light medicine, application of LED lighting in medical treatment, light environment In a variety of topics such as the intelligentization of the system, health lighting products and healthy light environments are fully explained.
