How to choose the safest lamp

In 2000, energy-saving lamps quickly entered millions of households in China due to their low power consumption and long life. By 2009, the penetration rate had reached 90%.

Is such a widely used energy-saving lamp really a carcinogen that lurks around someone?

  Ultraviolet radiation is the cause of carcinogens to achieve the same lighting effect. The energy consumption of energy-saving lamps is only 1/5 of that of ordinary incandescent lamps, but the life is 6 times that.

Because of this advantage, energy-saving lamps are being popularized worldwide.

But discussions about its security have never stopped.

  In January of this year, an article in Scientific Life in the United States stated that researchers at the State University of New York discovered through experiments that energy-saving lamps have stronger ultraviolet radiation than incandescent lamps.

Researchers first tested the UV emissions and phosphorescent 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 the skin cells affected by the ultraviolet radiation of the energy-saving lamp were severely damaged, but the skin cells exposed to the incandescent lamp were not harmed.

Researchers say that the ultraviolet radiation emitted by energy-saving lamps can damage human skin cells, cause premature aging, and even lead to fatal skin cancer.

  Not only that, the British “Daily Telegraph” reported that scientists at the Alab laboratory in Berlin, Germany, recently researched and found that when energy-saving lamps work, they can 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 increases 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.

  There is no need to panic about the limited amount of radiation. There are many opinions from experts at home and abroad on whether energy-saving lamps cause cancer.

Zhang Jie, an associate professor of the Department of Physics at Jinan University, said that traditional incandescent lamps use tungsten filaments to emit light. When the current passes through the tungsten filaments, the filaments will illuminate, and the energy-saving lamps emit light differently.

After the energy-saving lamp is powered on, the mercury atoms in the lamp tube emit ultraviolet rays that are invisible to the human eye, and the ultraviolet rays hit the phosphor coating on the inner wall of the lamp body and are converted into visible white light.

Researchers at the State University of New York believe that once the phosphor layer is broken, the ultraviolet light will “flee” out of the lamp, threatening people’s health, and the spiral energy-saving lamp is as much as possible.

  Experts from the National Electrical Manufacturers Association and the North American Lighting Engineering Association have stated that the ultraviolet content emitted by energy-saving lamps is very low, within the range that people can afford.

  ”Ultraviolet has confirmed a certain degree of damage to skin cells, but it must be high-intensity, close-range, continuous irradiation.

“Lin Yandan, associate professor of the Department of Light Source and Lighting Engineering at Fudan University, told the Life Times reporter that in general, as long as it is a qualified energy-saving lamp, it will meet the” Photobiological Safety of Lamps and Lamp Systems “standard and control the amount of ultraviolet radiationWithin safe range.

The light wave radiation will attenuate with the increase of distance when transmitting, so the distance between the human body and the energy-saving lamp is critical.

With luminaires with a cover, a part of the ultraviolet radiation is filtered out, so there is no need to panic too much.

Lin Ruozi, an authoritative optical expert at the Institute of Building Physics of the Chinese Academy of Building Sciences, also said that the intensity of ultraviolet light emitted by energy-saving lamps is limited, and there is little problem in daily use.

  How to choose the safest lamp for the lamp From the analysis of the experts, we are not serious that the key to the safety of the energy saving lamp is the amount of radiation. Therefore, strict quality assurance is especially important.

However, the previous highest rate of quality supervision and random inspection of energy-saving lamp products generally exceeded, and the overall national qualification rate was only 39.

3%, which can’t help but be worrying.

Fundamentally, experts suggest that the existing recommended national standards should be upgraded to mandatory standards and merged into the CCC certification standards for lighting fixtures to ensure the quality of energy-saving products.

  Three or four dollars of low-quality energy-saving lamps are best not to buy.

“When consumers buy energy-saving lamps, they must choose products with CCC certification in the store.

Lin Yandan is outstanding.

The reporter learned in the survey that the market for high-quality energy-saving lamps of large brands is generally tens of yuan or more, while low-quality energy-saving lamps only sell for three or four yuan.

Consumers do not want to be cheap, so as not to buy inferior products.

  There are tips for choosing high-quality energy-saving lamps.

The staff of the Jilin Provincial Administration for Industry and Commerce introduced that high-quality energy-saving lamps have a smooth appearance, fine workmanship, and no air bubbles. The phosphor coating in the lamp tube should be delicate, no particles, uniform white, and no blackening;There is no sound of slag slag inside; the connection between the lamp holder and the lamp body should be solid, and it can be repeatedly installed on a lamp holder, and the lamp holder is loosened and replaced again;

  Keep a distance of 30 cm from energy-saving lamps.

According to a study published by the British Health Protection Agency, when energy-saving lamps are kept at a distance of 2 cm from the human body, their UV intensity can reach the level of summer sun exposure, which may be harmful to health.

Therefore, Lin Yandan recommends that when using energy-saving lamps daily, it is best to maintain a distance of more than 30 cm, or install a glass lampshade to isolate ultraviolet radiation, and the daily use time should not exceed 8 hours.

Incompletely developed infants and young children should reduce the use or use of energy-saving lamps; bedside lamps and table lamps and other lamps that require close and continuous use, it is best not to use energy-saving lamps.
  Avoid direct contact with broken energy-saving lamps.
If you accidentally break the energy-saving lamp, do not directly touch the debris with your hands. Wear rubber gloves to pick it up, replace it with a plastic bag, and keep the room ventilated for more than 15 minutes.

  Establish a recycling treatment mechanism as soon as possible.

Lin Yandan said that mercury pollution in energy-saving lamps caused great pollution.

It is a toxic substance that the human body absorbs more than 2 at a time.

5 grams can cause death, and there is currently no complete set of recycling methods.

It is recommended to establish a reasonable recycling mechanism as soon as possible to reduce its environmental pollution.
