What is the light source of LED corn bulbs is healthiest ?
At present, a lot of LED corn bulbs used in shopping malls, household, office and other indoor lighting, but people do not know specific choose what light source of LED corn bulbs, how is it quality, if did harm to health are unclear. So, what is the light source of LED corn bulbs is healthiest ?
We usually use natural light is the sun, the sun can be divided into three parts, one is ultraviolet (uv), from 250 to 400 nm wavelength, two is to visible light, glittering in the 400-750 nm, three is near infrared, between 750 and 2500 nm wavelength.With ultraviolet (uv) and near-infrared produce bad effect to the skin, such as can make the skin to blacken, cause skin irritation, the phenomenon such as aging, rough, but the amount of ultraviolet ray also can bring certain benefits, such as promoting calcium-phosphorus metabolism and bone growth and development, etc.And the visible part, it is our human eye can see light, the blue light has the highest energy of the photons in the visible light, the eyes of retinal damage to a certain extent, but low radiation blue light have a good side, such as can whiten skin and teeth, can treat disease of infant jaundice, also can control people's clock, etc.
Into the era of LED lighting, blu-ray harm is often mentioned, because blue hazards in lighting without awareness, only in the use of scientific methods to guarantee security. LED lighting does not necessarily have blue light damage, it is determined by the amount of radiation and radiation time of the blue light.The radiation safety of LED lighting is higher than that of fluorescent tube, energy-saving lamp and gold halogen lamp under the same indoor illumination and color temperature.Different LED corn bulbs are made by different factory, and good quality LED corn bulbs blu-ray radiation is low.
Generally speaking, the greater the power of the LED corn bulb of blue light, the greater the damage, such as more than 20W LED light source, in use must pay attention to the installation height, the higher the height, the smaller the harm of blue light.In addition, the amount of blue light radiation decreases with the decrease of color temperature, while the small power LED light from 3500K to 2800K is basically in line with national standards.
But the current domestic many LED corn bulbs light source are mostly high color temperature , such as many LED to absorb dome light with more than 6500 k color temperature, while the LED corn bulbd for bedroom illume, this will cause a large blue light radiation, therefore, has the old man and the child's home in the home, should be considered.
TEK Lighting suggestion: commercial lighting, proposal use LED white light color temperature below 6000 k, highest do not exceed 6500 k. Office lighting, suggests to use 5000 k to 3200 k color temperature. Family lighting recommended power less than 8W LED corn bulbs , color temperature below 3500 k, it will be good for the health of the body.
