Energy-saving lamps are also carcinogenic. Recently, many foreign media such as "Scientific Life" reported that scientists have long-term research found that energy-saving lamps may pose a threat to human health and even induce cancer. In 2000, energy-saving lamps quickly entered China's thousands of households with its small power consumption and long life. By 2009, the penetration rate reached 90%. Is the energy-saving lamp so widely used, is it a carcinogenic culprit lurking around people?
Not only that, the British "Daily Telegraph" reported that scientists at the Alab laboratory in Berlin, Germany, recently found that energy-saving lamps will release a variety of carcinogenic chemicals, including phenol, naphthalene and styrene. toxin. Researchers believe that long-term use of energy-saving lamps or close contact will increase the risk of cancer. Experts from the German Federation of Engineers said that the electronic smoke emitted by energy-saving lamps is also a threat to health.
Regarding whether the energy-saving lamps are carcinogenic, experts at home and abroad have different opinions. Zhang Jie, an associate professor of physics at Jinan University, said that traditional incandescent lamps use tungsten light to emit light. When the current passes through the tungsten wire, heat is generated, and the filament is bright, and the principle of light-emitting of the energy-saving lamp is different. After the energy-saving lamp is energized, the mercury atoms in the lamp release ultraviolet rays that are invisible to the human eye, and the ultraviolet rays hit the phosphor coating on the inner wall of the lamp to be converted into visible white light. Researchers at the State University of New York believe that once the phosphor layer breaks, the ultraviolet light will “escape†outside the lamp, threatening people's health, and the risk of spiral energy-saving lamps is even greater.
Experts from the National Electrical Manufacturers Association and the North American Lighting Engineering Association said that the UV-emitting energy emitted by energy-saving lamps is very low, and that people can afford it.
Under the premise of achieving the same lighting effect, the energy consumption of energy-saving lamps is only 1/5 of that of ordinary incandescent lamps, and its life is 6 times. It is because of this advantage that the world is vigorously popularizing energy-saving lamps. However, the discussion about its security has not stopped.
How to choose the light lamp is the safest
In January of this year, the American Science Life article pointed out that researchers at the State University of New York found through experiments that energy-saving lamps are stronger than ultraviolet radiation from incandescent lamps. The researchers first examined the UV emissions and phosphor layers of energy-saving lamps and then compared the effects of energy-saving lamps and incandescent lamps on human skin cells. It was found that skin cells exposed to ultraviolet radiation from energy-saving lamps were severely damaged, while skin cells irradiated by incandescent lamps did not suffer any damage. Researchers say that the UV radiation emitted by energy-saving lamps can damage human skin cells, causing premature aging and may even lead to fatal skin cancer.
"Ultraviolet rays do cause some damage to skin cells, but the premise is high-intensity, close-range, long-time exposure." Lin Yandan, associate professor of light source and lighting engineering at Fudan University, told Life Times that in general, as long as Qualified energy-saving lamps will meet the standards of China's "Photobiosafety of Lamps and Lamp Systems", and control the amount of ultraviolet radiation within a safe range. The light wave radiation will decrease with the increase of the distance when it is transmitted, so the distance between the human body and the energy-saving lamp is critical. In the case of a luminaire with a cover, the UV radiation is filtered out a part, so you don't have to panic. Lin Ruoci, an optical authority at the Institute of Building Physics at the China Academy of Building Research, also said that the UV light emitted by energy-saving lamps is limited and has little problem with daily use.
From the analysis of experts, we can easily see that the key to the safety of energy-saving lamps is the amount of radiation. Therefore, strict quality assurance is particularly important. In recent years, China's energy-saving lamp product quality supervision and sampling pass rate is generally low, the national overall pass rate is only 39.3%, which can not help but worry. In this regard, many experts suggest that the current proposed national standards should be promoted to mandatory standards and included in the CCC certification standards for lighting fixtures to ensure the quality of energy-saving products.
It is best not to buy three or four yuan of inferior energy-saving lamps. “When consumers buy energy-saving lamps, they must choose products with CCC certification in the regular store.†Lin Yandan stressed. The reporter learned in the investigation that the market price of high-quality energy-saving lamps of big brands is generally more than ten yuan, while the inferior energy-saving lamps only sell for three or four yuan. Consumers should not be cheap, so as not to buy inferior products.
There are tips for choosing quality energy-saving lamps. The staff of the Jilin Provincial Administration for Industry and Commerce said that the high-quality energy-saving lamps have a smooth appearance, fine workmanship, no bubbles, and the phosphor coating in the lamp should be fine, no particles, even white, no blackening; when shaking the energy-saving lamps up and down There is no sound of slag ringing inside; the lamp head and the lamp body should be firmly connected. It can be repeatedly installed and unscrewed several times on one lamp holder. The lamp cap should not loosen and fall off; the center solder joint should not be too high, and should be even, Shine.
Keep a distance of 30 cm from the energy saving lamp. According to a study published by the British Health Protection Agency, when the energy-saving lamp is kept at a distance of 2 cm from the human body, its ultraviolet intensity can reach the degree of sun exposure in summer, which may endanger health. Therefore, Lin Yandan suggested that when using energy-saving lamps for daily use, it is best to keep a distance of 30 cm or more, or install a glass lampshade to isolate ultraviolet radiation, and use it for no more than 8 hours per day. Infants with incomplete development should reduce the use or non-energy-saving lamps; lamps that require close-range and long-term use, such as bedside lamps and table lamps, are best not to use energy-saving lamps.
Avoid direct contact with damaged energy-saving lamps. If you accidentally break the energy-saving lamp, do not touch the debris directly with your hands. You can wear rubber gloves to pick it up, seal it with a plastic bag, discard it, and keep it indoors for more than 15 minutes.
Establish a recycling mechanism as soon as possible. Lin Yandan introduced that mercury in energy-saving lamps can cause great pollution to the environment. It is a toxic substance, and a human inhalation of more than 2.5 grams at a time can lead to death. At present, China does not have a complete collection method. It is recommended to establish a reasonable recycling mechanism as soon as possible to reduce its environmental pollution.
