How to prevent LED blue light hazard
Who should pay attention to the LED blue light hazard
There are three types of LED lighting to be used with caution. The first type is children with delicate eyes. The lens of infants and young children is clearer and cannot filter blue light. The child has the nature of chasing light. It is exposed to a lot of blue light for a long time, which may lead to the retina of children. Phototoxic damage occurs, which can even cause tears in the retina, leading to blindness. The second type is diabetics. After more than ten years of development, diabetes has retinal lesions. The value of retinal light damage is greatly reduced. In addition, many drugs in life are photosensitive. After taking medicine, LED blue light The damage may be more pronounced. Finally, it is not advisable to use LED lights at night. Long-term use will affect sleep, and it will become a disorder of the biological clock, thus reducing human immunity.
What blue light is the most harmful
Related studies have shown that the blue light of different wavelengths has different effects on the human eye. The blue light between 435 nm and 440 nm has the greatest harmful effect on the eyes, and the effect gradually decreases as the wavelength increases or decreases. In the LED light source, since the white light emitted by most of the light sources is mixed by the blue LED chip and the yellow phosphor, the peak of the spectral energy is just in the blue light band, so that the proportion of the blue light energy is naturally high.
In life, there are many light sources that can emit blue light. In addition to Yuba, flat panel displays, LED neon lights, fluorescent lights, liquid crystal displays, ipads, large-screen mobile phones, etc., there are background light sources, and the light source excited by the powerful electron flow contains abnormal high-energy short-waves. Blu-ray will affect your child's retina and should avoid long-term direct vision.
How to prevent LED blue light damage
To prevent LED blue light hazard, the most important thing is to prevent the human eye from looking directly at the surface of the light source for a long time. For infants and the elderly with weak protection awareness at home, measures should be taken to prevent the light source from directly reaching the eye. In addition, in general, the proportion of blue light in a warm-colored LED is less than that of a cold-colored LED, and the surface brightness of a LED lamp with a diffuser cover is lower than that of an LED lamp without a cover or a transparent cover. When consumers purchase LED lighting products, they should pay attention to the color tone and surface brightness of the products.
