Europe introduced restrictions to avoid LED blue light problems

Europe has introduced restrictions to avoid the LED blue light problem. For those in the electronics industry, it is very important to have a thorough understanding of this problem. At this time, the international society 'stInternationalSymposiumofBlueLightSocietyThe following is an introduction to some of the content published by the society, and a review of the past restrictions on the impact of electronic products on the human body. I hope to help you learn more about Blu-ray. The 'blue light' problem of electronic products has finally attracted the attention of those in the display industry. Regarding 'blue lightAnd if you ask the display technicians, sometimes they will answer indifferently: 'Although there are many claims, but there is no evidence.' If you go to an optical shop, you will see the shop saying 'Protect your eyes from LCD TVs and LED lighting.' Advertisements such as anti-blue glasses for blue light damage. An ophthalmologist will say that the human eye has two functions: 'imaging' and 'clock'. Blue light has a great relationship with the eye. Some ophthalmologists have begun to remind people to be wary of the effects of blue light on human eyes. This meeting was held at the appeal of Kazuo Tsubasa, a professor in the Ophthalmology Department of Keio University School of Medicine, Japan. Distinguished ophthalmologists, psychiatrists, electronic component researchers, European CIE (International Commission on Illumination) and LED manufacturers and other relevant persons from related institutions and industries around the world delivered speeches at the conference. Unfortunately, people in the display industry did not give a speech, but the theme and content of the conference are worth listening to. Let’s first talk about the effect of blue light on imaging. Experiments in mice have shown that if the eyes are over-exposed to blue light for a long time, the possibility of causing 'age-related macular degeneration' cannot be denied. Age-related macular degeneration is a difficult and difficult disease, and the ** test using iPS cells has now begun. According to the ophthalmologist who delivered the speech, the diameter of the human retina that can be focused and imaged is only about .mm. There is a substance called lutein in the macula with a diameter of .～mm. The role of lutein is to block blue light and protect the retina, thereby protecting eyesight. If excessive blue light is irradiated, the macula will be damaged and cause age-related macular degeneration. It takes a long time to verify the mid-to-long-term effects of blue light, and now users of electronic products have begun to wear anti-blue glasses. Professor Sliney of Johns Hopkins University in the United States pointed out at the society: 'Although wearing anti-blue glasses is not a mandatory requirement at present, there is no reason to deny users that they should be equipped with anti-blue glasses for insurance purposes.
