Be alert to the dangers of LED lights
LEDs are everywhere, affecting every aspect of human life.
With the rapid spread of LED technology around the world, people's concerns have gradually changed. Previously, everyone focused on visual elements and energy-saving links; today, researchers are beginning to focus on LED lighting and health issues.
LED white light causes great damage to human eyes
Perhaps people have been harmed by LED white lights, but they have not been discovered. The following is an analysis of the researchers.
The study found that people who work and live in LED white light pollution environment for a long time, the retina and iris will be damaged to varying degrees, the visual acuity drops sharply, and the incidence of cataract is as high as 45%. It also makes people feel dizzy and upset, and even suffer from symptoms such as insomnia, loss of appetite, depression, and physical weakness.
In the summer, the strong reflection of the glass curtain wall enters the nearby residential buildings, increasing the indoor temperature and affecting normal life. Some glass curtain walls are semi-circular, and the reflection of light is also likely to cause fire. Drivers driving under the scorching sun will be unexpectedly attacked by the reflected light from the glass curtain wall. The eyes are strongly stimulated and it is easy to induce a car accident.
According to optical experts, the reflected light of mirrored building glass is stronger than that of sunlight, and its reflectivity is as high as 82% to 90%. The light is almost completely reflected, which greatly exceeds the range that the human body can bear. People who work and live in a white LED bright and polluted environment for a long time may easily lead to decreased vision, dizziness, insomnia, palpitations, loss of appetite and depression, and other symptoms of neurasthenia, which may cause changes in normal physiological and psychological changes. Long-term will induce certain diseases.
LED lamps have harmful heavy metals
The famous American science magazine "Scientific American" also pays attention to the negative effects of LED lights. Although LED lamps have become very competitive due to their energy-saving performance, research papers have pointed out that LED lamps contain lead, arsenic and dozens of other dangerous substances.
Of course, white LED lamps have the least lead content, but there is still a large amount of nickel, a heavy metal that can trigger an allergic reaction. In addition, the level of copper found in some LED lamps may pose a threat to the environment, and if accumulated in rivers and lakes, it may poison aquatic organisms.
Experts say that although it is less likely to cause cancer after inhaling an LED, it is not necessary to let toxic substances float around. If the LED light is broken at home, it is recommended to wear gloves and a mask to clean it. In addition to the debris, even the cleaned broom should be discarded.
In addition, when people go to the scene of a car accident to deal with a car accident, or when repairing a damaged traffic light, they should wear protective clothing and dispose of the waste according to the standard of hazardous waste. It is said that LED lights are not currently classified as toxic by law and can be disposed of in conventional landfills.
Expert reminder
● The National Sleep Foundation recommends not using technology products for more than 30 minutes before going to bed, and there are no technology products in the bedroom.
● Although an LED light is broken, inhaling its smoke is unlikely to cause cancer, but there is no need to let more toxic substances float around. If the LED light is broken at home, it is recommended to wear gloves and a mask to clean it. Even the cleaned broom should be discarded.
● When people go to the scene of a car accident to handle a car accident, or when repairing a damaged traffic light, they should wear protective clothing and dispose of the waste according to the standard of hazardous waste.
