Shocked: When the energy-saving lamp is illuminated, it will cause damage to the skin?
The British Health Protection Board issued a warning on the 9th that if it is too close, some of the energy-saving lamps produce ultraviolet rays that are enough to damage the skin. Therefore, those who like to read a book in bed with a desk lamp are advised not to use energy-saving lamps that are exposed to the lamp. However, they also let everyone not be afraid, in general, as long as you leave the bulb 30 cm, it is very safe.
People lying down reading books may be affected
In order to reduce emissions, the UK is working hard to promote energy-saving lamps and is preparing to completely eliminate incandescent lamps in 2011. However, the British Government's Health Protection Committee found that the UV light emitted from the lamp was too close to the energy-saving lamp to make the skin red and itchy.
Those who are often close to the light bulb are probably the most affected. For example, jewelers and watch craftsmen need to put their hands under the light bulbs, and many people like to read books on the bed with a desk lamp. Those who are allergic to UV are especially careful when choosing a light bulb. Thousands of people in the UK seek medical attention every year because of UV allergy.
The British Health Protection Board recommends that these people should switch to bulb-type energy-saving lamps.
The safety distance is 30 cm
British energy-saving lamps come in two shapes, one is the usual open type, the tube is directly exposed to the outside; the other is the wrapped bulb type, and there is a glass cover on the outside, which looks like a traditional incandescent lamp.
Studies have shown that if the skin is close to an open energy-saving lamp, the distance is less than 2.5 cm, then the intensity of the UV light is equivalent to a sunny summer day.
If a person is less than 30 cm away from an open-air energy-saving lamp, the ultraviolet radiation received is equivalent to staying outdoors on a clear winter day. However, more than 30 cm will not be a problem.
Therefore, if the distance from the light source is less than 30 cm per day and the time is more than 1 hour, the open energy-saving lamp should not be used. Instead, the bulb-type energy-saving lamp should be used instead. The ultraviolet light emitted by it is negligible and negligible.
No need to use energy saving lamps
But Justin McClecken, vice chairman of the UK Health Protection Board, said: This is just a precautionary warning, and people don't have to worry about disabling energy-saving lamps at home. If you want to be close to the light, the solution is very simple, just replace it with a light bulb. I walked around my home and found no one less than 30 cents from me.
McLeken said that the statement that incandescent lamps can cause skin cancer is not correct: we did not say that, in fact, according to the amount of ultraviolet light we said, the worst result is that the skin will be red for a short time. We do not believe that such light levels can cause skin cancer.
Since the advent of energy-saving lamps in the 1980s, no problems have been discovered before. However, the committee believes that since existing products have such hidden dangers, they should inform the public and they will also promote the EU to improve product standards.
tips
14% of the electricity in the EU is consumed by lighting. If all incandescent lamps are changed to energy-saving lamps, this part of the electricity is expected to save 80%.
When an ordinary incandescent lamp is working, most of the energy is wasted in the form of infrared radiation. Due to the high temperature of the filament, the life is greatly shortened. Energy-saving lamps not only have a long life, but also achieve the same brightness, which consumes only 1/5 to 1/4 of the power consumption of ordinary incandescent lamps.
