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.
