Does the LED eye protection desk lamp have blue light?
LED lighting is a green light source, and it is also the result of the development of the third-generation lighting technology after incandescent lamps and fluorescent lamps. Nowadays, many people are using LED eye protection desk lamps, but I don't know if LED eye protection desk lamps have blue light. Based on this question raised by everyone, I hope you will read it carefully.
After investigation, the editor found that the LED eye protection desk lamp has blue light, but blue light is harmful, and it is recommended that you do not use it. The reason why the white light emitted by the light source of the LED eye protection desk lamp can be formed mainly depends on the blue light of 450-455NM wavelength to excite the phosphor, and the lower the wavelength, the stronger the firing ability. Usually, the factory wavelength of LED light source is controlled within 500NM, generally 450~455NM or 455~460NM, which belong to the section with the strongest radiation damage. If the wavelength becomes larger, the ability to excite the phosphor decreases, and the luminous efficiency decreases. In order to pursue brightness, manufacturers usually strengthen the blue light intensity of LED light sources. If the human eye looks at such a light source for a long time, it is inevitable that the eyes will be damaged by blue light.
The effects of blue light have been well understood by sleep researchers and scientists for many years. Circadian rhythms determine our internal biological clock. Those who were accustomed to going to bed late had longer rhythms than those who were accustomed to getting up early. Sunlight usually keeps these rhythms in line with our environment, and blue light therapy is often used to alter sleep patterns and treat sleep disturbances.
