Analysis of LED lamp light is harmful to the eyes

Introduction: what is the light of the LED lamp really harmful to the eyes? This is a question worth exploring and giving the exact answer.

In recent years, the further production and promotion of energy-saving products, as well as the enhancement of people's awareness of energy saving, incandescent lamp gradually fade out of our lives, replaced by fluorescent lamps and light-emitting diodes and other new light sources. But it also brought problems, such situation is certainly gratifying, but higher than the incandescent lamp light source in the blue light proportion, many people reflect the eye fatigue and other health problems in LED irradiation. In particular, the use of computers, mobile TV is getting longer and longer, and we have come into contact with the LED Blu ray also increased a lot, which also had to raise concerns about LED Blu ray irradiation.

After all, is the light of LED lamp really harmful to the eye? This is a question worth exploring and giving the exact answer.

Analysis of LED lamp light is harmful to the eyes

We are exposed to the natural light of the sun, and the human eye is also a product of the evolution of life, and has adapted to the sun as a light source for a long time. Different wavelengths of visible light cause us different color vision, according to the wavelength of light from long to short order, we feel the colors are: red, orange, yellow, green, green, blue, purple. Blue and purple are visible wavelengths of light. When these light waves of different wavelengths come into our eyes at the same time, we feel the white light. Newton's famous experiment is to make a beam of sunlight through the three prism, white light is decomposed into seven color spectrum. People are most sensitive to yellow and green light, which is the longest wavelength on the earth's surface. From the yellow green light to the short wavelength blue and purple direction, intensity gradually weakens. There is a certain amount of ultraviolet and infrared light in the solar spectrum, but the human eye is not sensitive to ultraviolet and infrared. Infrared radiation on our skin, it will cause a sensation of heat, so also known as thermal radiation. Ultraviolet radiation is too strong or too long time will burn the skin, but also damage the eyes.

The spectrum of the incandescent lamp, as we know it, is similar to that of the sun, which gives off light orange, which is a more acceptable color in the history of human evolution. While the LED light-emitting principle is different with the incandescent lamp, have more blue hair in the spectrum, near the wavelength of 450 nm is a strong blue light, although from the economic point of view this light is the most affordable, but the solar spectrum and eye habits have a greater difference, if things go on like this on people's will, bad eyes damage to health. Now the era of rampant color, blue is distributed to our eyes poison three points.
