Analysis: LED light source on human and biological safety and health effects

Semiconductor lighting extending to the health field

On July 19, 2011, alliance national semiconductor lighting project held a theme of "security" LED source of human and biological salon in Shanghai Yi Fu of Fudan University science and technology building, more than thirty experts from different fields and industry representatives gather together, around the theme of warm and deep. The meeting for the effect of LED on the retina, skin, how to make good use of the LED light source is discussed in great detail, meticulous to every wavelength affect what kind of creature, which should be carried out on the effect of light on the human body, melatonin, and the change of biological rhythm, biological clock.

"Today's discussion makes us feel very exciting, experts in various fields can be said that there is a consensus that LED gave us a choice of light source, when we need a kind of effect, we can control him to realize, the future of the LED enterprises can have more space for the development of products the application, to make different products according to different wavelength, of course, the research aiming at the application there are also many. Now we have a part of the research has been in the international arena, we should keep pace with the international leader in many aspects. Lin Yandan said in the summary of the future direction of LED.

To the salon with Professor Zhou Taiming from the Fudan University, Hangzhou Zhejiang tricolor Instrument Co. Ltd. chairman - rise, the national electric light source quality supervision and Inspection Center (Shanghai) deputy director Yu Anqi and other well-known industry experts, Fudan University and Shanghai medical college professor of Ophthalmology, Zhongshan University School of medicine from Gu Huaiyu medical science and Visual Sciences, deputy director of the Department of Qu my eye Shanghai Medical School of Fudan University professor and deputy director of Visual Sciences Ding ang, Yang Weiling director of the Department of Dermatology General Hospital of the Second Artillery China people's Liberation Army, as well as the domestic and foreign well-known enterprises such as LED, the Salon special support unit, Shanghai NVC lighting, Benjamin Bulb Factory Co. Ltd. and Nanjing Henderson Polytron Technologies Inc, beautiful lighting, Tsinghua Tongfang, PHILPS, CREE and photoelectric products enterprises such as high The layers represent the salon discussions. All aspects of the representatives of the wonderful speech so that the atmosphere of the salon is very active, bursts of applause and laughter from time to time to stimulate the laughter is always accompanied by the salon.

"I've never been able to get so much information at a seminar! Lin Yandan, associate professor of light source and lighting Engineering Department of Fudan University, presided over the "LED light source for the safety and health of human beings and the biological impact," said Sharon excitedly.

Health lighting project deployment

As a new type of light source, LED lighting technology has achieved rapid development in recent years. At the same time, the LED light source is also more and more concerned about the safety of the human eye and the biology. What is the effect of the LED light source on the human eye? LED as a healthy lighting carrier will be more widely used in our lives, so in different occasions, how to determine the safety of LED? For LED health lighting, is there a quantitative standard? How to use the results of research and development of health lighting and the market, and guide enterprises to develop more secure, healthy LED lighting products? All of these are related to a very important issue - the safety and health of biological.

In recent years, LED has attracted more and more attention from the international community. CIE (City) in South Africa (Sun) just concluded the twenty-seventh session of the general assembly, bio safety and health lighting is also a hot topic of discussion. China in 2010 ahead of the launch of the "863" plan in 12th Five-Year, a major project of semiconductor lighting LED photometric, colorimetric and health lighting research has been deployed on the health of LED lighting. The research goal of the project is: the development of LED lighting products luminance distribution, glare, color and intermediate visual evaluation techniques; the establishment of LED biological health and hazard evaluation method and evaluation platform; carry out LED non imaging optics research and establish database design. The main research contents of LED lighting products luminance distribution, glare, color and intermediate visual evaluation and measurement technology, and Research on the health of LED lighting optical biological effect based on the establishment of LED lighting products, health and hazard evaluation and measurement platform.

Because LED is a point light source, if used improperly or not qualified, the harm to the user will be very large. With the increasing application of indoor and outdoor large power semiconductor lighting products more widely, "12th Five-Year" semiconductor lighting special planning also plans to deploy high power semiconductor lighting products light radiation safety research project, research on the radiation characteristics of semiconductor lighting products for the light source and the semiconductor lighting, making hazard limits and hazard classification, develop hazard detection method and device of optical radiation of semiconductor lighting products with independent intellectual property rights.

"LED light source of the safety and health of urgent and significant, it is not only related to the feasibility of the application of LED as a new light source and market acceptance, the other a new sky and you can open the LED application, to the health of these broader application fields extending commercial space and opportunities, this is very interesting, it is very instructive. "A business representative said so. This is precisely the purpose of this salon activities, on the one hand, a wide range of opinions on the subject of national collection, on the other hand to guide the development of LED applications
