At present, China has become the world's largest LED lighting production country. However, the recent news that medical experts worry about the blue led tube manufacturer will retinal damage, even blindness. Online, the news aroused extensive attention from netizens and forwarding comments.
LED lights with Blu-ray is really so much harm? the so-called "Blu-ray overflow" really hurt the eyes "potential killer"? January 6, the Shanghai Municipal Bureau of Quality Supervision specialized organizations testing organization on the part of the LED lighting products risk monitoring, the Blu-ray risk testing 27 samples were collected from different sources. At the same time, it is also the first "cross-border" invite the medical profession, universities and industry experts together "consultations" to listen to the views of all parties.
Related standards in China is not lagging behind
There is a voice that, because of the lack of appropriate standards, led bulbs manufacturer Blu-ray failed to arouse the attention it deserves. In this regard, the Shanghai Lighting Products Quality Supervision and Inspection Zhanfuzhanchang Yuan Qi, chairman of the Shanghai Illuminating Engineering Society introduced the 27 sample detection based on - the national standard GB / T 20145-2006 lamps and lamp systems biological Security. " According to reports, the standard was released in 2006, but the current international standards and the current version is equivalent. That is to say, in terms of the development of standards, we developed Western countries are synchronized and do not fall in behind.
The current problem is that this standard is the recommended standards, rather than a mandatory standard, the standard execution compromised. Therefore, the parties "consultations" on the consensus reached: the need to enhance the properties of this standard is mandatory and included in the lighting CCC certification standards.
"Demonized" Blu-ray unscientific
Blu-ray is whether, as the rumors say so terrible? Experts pointed out that Blu-ray has always existed in nature light is sunlight important part in a variety of white light source must exist. This means that the environment we live in is not possible "off Blu-ray, Blu-ray" demonized "is clearly unscientific.
As for the Blu-ray hazards, attended by representatives of the medical profession, the chief physician of the ENT Hospital of Shanghai Jiang Chunhui: "a foregone conclusion in recent years for the mice trials, Blu-ray damage to the visual cells continue to emerge, and in-depth research." Yuan Qi hold a different view, he pointed out that in the the intensive exposure spokes "rich blue" Environment and normalized environment are two different concepts. But he also stressed that, precisely because of the attention to the rich white mr16 led bulbs lighting products Blu-ray spectra, only the light biohazard international standards, in order to prompt the safety of the product should reach.
Optoelectronic Information Engineering of Zhejiang University Professor, Department of MOU Tong-sheng, the limits of the current standard is based on adults and 8 hours exposure spoke experimental data, not yet consider the long-term effects of the accumulation of light on the human body and certain special populations, such as infants and young children may long look directly at the light source, thereby causing damage to the retina. ZHANG Shan-end, the deputy director of the Lighting Research Institute of Fudan University, suggested that future standards development should stringency should be wide.
The experts suggested that the standard specifies 0 (non-hazardous) and Class 1 (low risk) products are safe to use, but for special populations should be clearly 0 products.
