The deployment of health lighting as a new type of light source, LED lighting in recent years has achieved rapid development in technology and applications. At the same time, the safety of LED light sources to human eyes and organisms is also receiving more and more attention: What is the effect of LED light sources on the human eye? LED as a carrier of healthy lighting will be more widely applied to our lives. In China, then how do you determine the safety of LED in different occasions? Is there a quantitative standard for LED health lighting? How to use the research results of healthy lighting to truly integrate with the market and scientifically guide enterprises to develop safer and healthier LED lighting products? All of these involve a very important issue - light biosecurity and health.
In recent years, the light bio-safety of LED has increasingly attracted the attention of the international community. At the 27th CIE Conference in Sun City, South Africa, light bio-security and health lighting were also a hot topic of discussion. China's “12th Five-Year Plan†863 Plan, which was launched ahead of schedule in China, is a major semiconductor lighting project “LED Luminosity, Colorimetry and Healthy Lighting Research†that has deployed LED health lighting. The research objectives of this project are: to develop evaluation technologies such as brightness distribution, glare, color rendering, and intermediate vision of LED lighting products; to establish LED light bio-health and hazard assessment methods and evaluation platforms; to develop LED non-imaging optics research and establish a design database. The main research topics include LED lighting product brightness distribution, glare, color rendering and intermediate vision evaluation methods and measurement techniques, as well as the study of LED health lighting based on photobiological effects, establishment of health and hazard assessment methods and measurement platforms for LED lighting products, etc. .
Since the LED is a point light source, if it is used improperly or the light distribution fails, the harm to the user will be very great. With more and more applications of indoor and outdoor high-power semiconductor lighting products, the 12th Five-Year Plan for Semiconductor Lighting also plans to deploy a high-power semiconductor lighting product optical radiation safety research project, mainly for semiconductor lighting products and semiconductor lighting products The characteristics of light radiation were studied, hazard limits and hazard classification were formulated, and optical radiation hazard detection methods and testing equipment for semiconductor lighting products with independent intellectual property rights were developed.
"The research on the safety and health of LED light sources is urgent and significant, which not only concerns the feasibility and market acceptance of LED as a new light source, but also opens up a new horizon for LED applications - to health care. The commercial space and opportunities for these broader application areas are very interesting and instructive,†said a representative of the business community. This is precisely the purpose of this salon event. On the one hand, a wide range of opinions are collected for national issues, and on the other, LED innovation applications are guided.
Reasonable design and use will allow LED to extend from safety to health applications. Professor Fudan University’s Professor Zhou Taiming stated that the public is concerned that LED will harm human eyes and many experts are afraid to use it. The former chairman of the International Commission on Illumination also had a process for the use of LEDs. At the beginning, he also had doubts about LEDs. But now his attitude is very positive and he has done a lot of research work. He has an article called "Inconsistent Quality and Energy Efficiency of Lighting." This document focuses on the impact of LEDs on human injuries. At the same time, calculations were made at the same time. The conclusion is that we can use the white LED with a color temperature of 2700K-3000K and a color rendering index of 80 or higher. The use of 6000K at home will hurt.
In addition, Professor Zhou also made a report on Tian Yan, a dermatologist at the Beijing Air Force General Hospital who was unable to attend due to physical reasons, and introduced Tian’s work in light biosafety. Dr. Tian Yan invited more than 30 volunteers to accept a 30-day lighting experiment. The lamps used LED light source and the color temperature was 2800K. The experiment found that the volunteers' skin did not change. So the experimental results prove that LED lighting is safe for the skin. At the same time, a fluorescent lamp contrast experiment was conducted. The results showed that the fluorescent lighting was harmful to the skin, and the color of the skin changed. The L value decreased, the M value decreased, the A value increased, and the E value increased. The color of the skin turns red, and the water content of the skin also tends to decrease.
President Zeng Tongsheng of Hangzhou Zhejiang University’s Tricolor Instrument Co., Ltd. just returned from South Africa to participate in the IEC conference. At the meeting, he participated in the formulation of photobiological safety standards. He introduced the international work in this field. Lou Dongsheng, chairman of the Board of Directors, urged everyone to pay attention to the light bio-safety of LED products. In the future, with the increase of LED light efficiency and brightness, the potential for harm to human eyes will increase. However, he is confident that LED can be designed better. LED has conditioning effects on human cell metabolism and can make people's body stronger.
Yu Anqi, executive deputy director of the National Electric Light Source Quality Supervision and Inspection Center (Shanghai), described how to determine the safety of LEDs in different applications. He said that the spectrum of LEDs actually makes safety protection relatively simple, as long as there are different goals. Application site. Once the LED enters the interior lighting, its safety becomes more important. For enterprises, the development of products must be targeted. In terms of light efficiency and light comfort, different choices must be made depending on the environment of use. They cannot be generalized.
Lin Yandan, an associate professor of light and lighting engineering at Fudan University, believes that in the era of LED new light sources, we only grasp what people really need, grasp the characteristics of the spectrum and adjust the spectrum, that is, fully consider the radiation of light, and consider people’s Visual and security needs to achieve a better and healthier lighting.

The company will be the concept of traditional light source implanted into the LED lighting Products, focus on optical design, attention to glare, color temperature, color rendering index and other indicators.
Gu Huaiyu, professor of neuroscience at Sun Yat-sen University School of Medicine and an expert in neurobiology, is optimistic about LED lighting. He believes that scientifically rationalizing the space-time layout of industrial development and looking for a solution to reducing LED biohazards from a technical perspective is not only related to the healthy and sustainable development of the LED lighting industry. , And through the planning of national standards for LED lighting and the layout of related patents, the right to speak for standard setting will be crucial for the entire new semiconductor lighting industry to break patent barriers and nurture new generation lighting core technologies with independent intellectual property rights. Strategic significance.
Wu Xiaomei, deputy director of the department of ophthalmology and visual science at the Shanghai Medical College of Fudan University, discussed what kind of lighting is more appropriate from the medical point of view. She believes that lighting must be safe and does not cause visual fatigue. In order to achieve a comfortable lighting business needs Make joint efforts with R&D institutions.
The Director of the Department of Dermatology of the Second Artillery General Hospital of the Chinese People's Liberation Army, Yang Weiling, believes that the effects of LED on human eye safety should be studied and observed for a long time. In the treatment of skin diseases, more and more attention is paid to light. Many skin diseases are difficult diseases such as psoriasis and vitiligo. LED should be promising in the treatment of skin diseases and beauty, but it also needs in-depth research.
Dr. Ding Aung, deputy director of the department of ophthalmology and visual science at the Shanghai Medical College of Fudan University, said that they are conducting research on the treatment of breast cancer and mastitis in LED and hope that the LED can be developed in more depth and treated as a product.
Li Qian, deputy director of the Institute of Electric Light Sources at Hangzhou Yuanfang Optoelectronics Information Co., Ltd., believes that China's research in light radiation is at least in sync with the world's leading. For lighting companies, the standards that focus on lighting and health are currently only CIE and S009. It is not difficult to measure some of the light radiation of existing standards. However, the utility of how to use LEDs needs further in-depth study.
The impact of LED light sources on the safety of human eyes and organisms is indeed a very important issue. This salon has received positive feedback from the medical community, LED academia, and the business community. It believes that as long as it follows the correct indicators, reasonable design, and appropriate Application, LED light source is safe. Not only that, LED light source is also very promising in the health field, it can be turned into a beauty light, but also to prevent the occurrence of some skin diseases, the regulation of biological rhythm, etc. have a good supporting role. In terms of standardization and measurement of light security, a lot of work has been done at home and abroad, but there is still a lot of room for research in the future. It is believed that in the future through standard testing standards, through a variety of basic research, through industry, research, even LED field and medical field, etc., cross-border cooperation, future LED in the safety lamps, health lamps, and even light treatment lamps are promising.
