Swedish experts say LED will cause headache and other symptoms

According to the Swedish news "message:" today more and more families and office units are LED lamps, but the Swedish expert at Longde Polytechnic expressed concern because experiments show that on the market today LED will cause headache, decreased attention, visual impairment.

Six years ago, the Swedish market LED lights successfully replace the old light bulb. Many families, work units and public places have begun to use the new LED energy-saving lamps. The innovation of electric light technology brings the possibility of energy saving. However, experts at the Institute of technology in Longde, Sweden, Dr. Han Wei, said some concern. South Korea this year on the Swedish market, the fifty LED energy-saving lamps to do a survey, the results show that most of the products have quality problems. He told the media that consumers can not judge the quality of these lamps, the price can not explain. These quality problems are not due to LED technology, but rather the problem of assembling structures.

Dr. Han said that the market is selling a lot of LED lights using pulse power supply, the cost is relatively cheap, while helping to adjust the brightness of light, but also to extend the service life of the lamp. However, it is not a continuous light, but at a very high speed flashing, we can not feel the naked eye, only the brain and retina can be detected. This can lead to headaches, decreased attention and decreased vision.

Staff of the Energy Bureau of the Ni Chi told the media that the government should pay attention to this problem, improve laws and regulations, so that substandard products disappear from the market. At the same time, he also stressed that LED energy-saving lamp technology will be getting better and better, and the old light bulbs, LED lamp consumption is 1/10, for energy conservation is also a positive significance.
