What are the assessment methods for the blue hazards of LED lamps?
The damage of blue light to the retina is mainly caused by excessive radiation at a wavelength of 400-500 nm. The measurement results calculated by various light sources and fluorescent spectral data and the domestic and foreign authoritative laboratory showed that the blue content of white LED light source is not higher than the same color fluorescent lamp and metal halide lamps and other traditional light source and the light of the sun; white light LED light source in the retina of blue light exposure and fluorescent lamp and metal halide lamp similar to conventional light sources safety, lighting products belong to the 0 class and 1 class.In order to ensure the biological safety of LED lighting products and lighting quality, LED light source and lighting system must comply with the relevant standards at home and abroad, and the reasonable optical design, will be a smooth surface brightness control at the right level. When used, the illuminance and color temperature used should be determined according to the specific application.
Similar to traditional light sources, the correct use of qualified ordinary illumination white light LED products is completely safe for the human eye
In fact, LED's Blu ray isn't that serious, but it's exaggerated. Recently, experts have such conclusions:Blu ray is the basic component of white light. Like sunlight and traditional light sources, white light LED also contains blue light. Proper blue light is not only necessary to ensure the color rendering of light source, but also can regulate the circadian rhythm of human body.
To prevent LED blue light hazards, the most important thing is to avoid the human eye for a long time looking directly at the light source surface, for home protection of weak awareness of infants and young people, should take measures to prevent light sources directly into the eye. In addition, the blue light in the warm color LED is less than the cold tone LED, and the brightness of the LED lamp with the diffuser is lower than that of the LED lamp without a hood or with a transparent cover. When buying LED lighting products, consumers should pay attention to the tone and brightness of the products.
