Do you know which LED light source to choose is healthy?
At present, LED lights are mostly used in indoor lighting, such as LED ceiling downlights, LED ceiling spotlights, LED panel lights, LED track lights and even some large chandeliers and ceiling lights used in shopping malls, homes, offices and other places. Many people are still at a loss as to which LED light source to choose. Most consumers just choose one and go back. talk about this topic.
Usually the natural light we use is sunlight, which can be divided into three parts, one is ultraviolet light with a wavelength of 250-400nm, the other is visible light with a wavelength of 400-750nm, and the third is near-infrared light with a wavelength of 750-2500nm. Among them, ultraviolet rays and near-infrared rays have adverse effects on the skin, such as darkening the skin, causing skin redness, aging, roughness, etc., but an appropriate amount of ultraviolet rays will also bring certain benefits, such as promoting calcium and phosphorus substitution Xie and bone growth and development, etc. The visible light part is the light that our human eyes can see. Among them, blue light has the highest photon energy in visible light, which has certain damage to the retina of the eye, but low-radiation blue light also has a beneficial side, such as whitening skin and teeth. , can treat infant jaundice, but also control the human biological clock.
But at present, blue light hazard is often mentioned by people, especially since the era of LED lighting. The light source does not necessarily have blue light hazards, and it depends on the amount of blue light radiation and the radiation time. Under the same color temperature and the same indoor lighting effect, the radiation safety of LED lighting sources is higher than that of fluorescent tubes, energy-saving lamps, and metal halide lamps. Generally speaking, the higher the power of LED lamps produced by different LED lamp manufacturers, the greater the blue light hazard. For example, the LED light source above 20W should pay attention to the high brightness of the installation. The higher the height, the less blue light hazard. In addition, the amount of blue light radiation will decrease as the color temperature decreases, and the low-power LED light source with a color temperature of 3500K-2800K basically meets the national standard. However, most of the lighting sources produced by many domestic LED lamp manufacturers are products with high color temperature. For example, many LED ceiling lamps use a color temperature above 6500K, and LED ceiling lamps are mostly used for room lighting, which will lead to a large amount of blue light radiation. Therefore, , in the home with the elderly and children, it should be carefully considered
Therefore, BENWEI Lighting recommends everyone: commercial lighting, it is recommended to use LED white light with a color temperature below 6000K, and the maximum is not more than 6500K; Below 3500K, this will be beneficial to the health of the body. LED lights, the LED blue light radiation of good quality LED light manufacturers is low.
