Ultraviolet radiation from lighting sources damages the human body and eyes - "UV damage"
Ultraviolet rays are classified into wavelengths: long-wave ultraviolet (UVA, 320 to 400 nm), ultraviolet (UVB, 280 to 320 nm), and short-wave ultraviolet (UVC, 200 to 280 nm). Studies have found that some light sources can easily leak UV light. For example, leaks through capillary cracks on the inner wall of energy-saving light bulbs can cause a certain degree of damage to skin cells.
State University of New York researchers have experimentally demonstrated that fluorescent energy-saving light bulbs emit more ultraviolet radiation than ordinary light bulbs. The skin cells irradiated by fluorescent energy-saving lamps are seriously damaged and may even induce cancer. The researchers first selected multiple brands of fluorescent energy-saving lamps to detect the leakage of ultraviolet light, found that most of the energy-saving lamps have UVA and UVC radiation; then choose the most powerful fluorescent energy-saving lamps, put it to a distance of 2.5 cm to continue Fibroblasts and keratinocytes cultured in vitro were irradiated, and the same cells were irradiated with an incandescent lamp as a control. The results showed that the cells under the fluorescent energy-saving lamp had a longer exposure time, and the damage was more serious; while the cells irradiating the incandescent lamp were not affected. In addition, the ultraviolet radiation of energy-saving lamps is not only between different brands, but also between different bulbs produced by the same manufacturer. After deciding on the preliminary findings of "energy-saving lamps carcinogens," researchers at the State University of New York suggested that the use of fluorescent energy-saving lamps should be minimized.
Researchers at the State University of New York have experimented to prove that energy-saving light bulbs emit more ultraviolet radiation than ordinary light bulbs. The test results showed that the phosphor layer of each energy-saving lamp tested was destroyed and emitted ultraviolet light. In fact, excessive exposure to ultraviolet light is one of the causes of senile cataracts. Under the influence of ultraviolet light, phosphorus ions may combine with calcium ions in the aging lens to form insoluble calcium phosphate, resulting in hardening and calcification of crystals. This is similar to the cataract patients living in the tropics, seaside fishermen, and cataract patients in Tibet, Qinghai, and other highland areas. Most of the causes of cataract are related to ultraviolet rays. ”
Seriously, cataracts are an eye disease with a high incidence of diseases. Currently, it is not limited to the elderly. Those who are mobile phone users, overtime workers, computer users, television fans, and drivers are all the main morbid subjects of cataracts. There are many kinds of cataracts, of which the radiation cataract must be related to the harmful radiation and poor light radiation environment of the lighting or display screen. Unqualified lighting fixtures, especially bad table lamps, are the culprit for radiation cataracts. Eyes are exposed to strong light, glare, and intrusion of microwaves, ultraviolet rays, and blue light, which can cause eye health damage.
The OLED light source brought by UIV OLED lighting can effectively avoid UV damage and can be more effective in visual health. OLED light source spectrum is close to natural light, no heat, no flicker, whether as eye protection lamp light source or home lighting light source is a very Good choice.
