LED for school lighting should be used cautiously

In September last year, the Taiwan Ministry of Education organized a seminar, conference was proposed official to attend. The proposed official money by the proposed pilot demonstration inside the school in Taiwan: LED lighting vision of students, put all the lights replaced with LED torches. But this is only proposed official favor, while others voted against, we can imagine, this proposal ultimately failed to pass.

In the past, the visual health of the Taiwanese students was consistently good. For various reasons - including the increase in the pressure of student learning, poor lighting conditions, and so on. Today, 90 percent of students in Taiwan all have to wear glasses. Responsible for the total review of a school lighting National Taiwan University of Science and Technology, Professor Xiaohong Qing in 1983, According to reports, at school, low lighting, illumination, reading very difficult, glare at the same time very serious, a great visual impact. Their approach was based on the standard of electronic ballasts to solve the problem of the screen flash screen flash to improve the environment, illumination, glare, screen flash have been improved, this has done very well in Taiwan, but also support the electronic The ballasts industry.

According to the research, blue and yellow phosphor, larger defects is Blu-ray 430-470 between the damage to the retina is relatively large, the current technology can be 430-470 lower, but even in this case, in the school inside the LED light source to improve classroom lighting or insufficient grounds, because it involves a security issue. Currently among the biggest problem is that Blu-ray damage to the eyes. Children before the age of 15 eye protection should be very careful, big people can not provide a bad reading, and injury to the student's visual health. Energy saving excuse for too inadequate to solve the problem of the light color temperature, or need time to assess. Should be careful and weight of the LED used in primary and secondary schools, taking into account the Blu-ray damage to the eyes, this damage is irreversible, not just adventure.

Not the pursuit of light effects, but be sure to pay attention to light environment. If do use LED lamp alternative classroom lights, a color temperature to reduce the second with the light to change, due to the China LED gadgets current price, promotion it may be difficult.
