Energy-saving lamps have strong radiation at close range and should not be used as bedside lamps and desk lamps
The electromagnetic radiation generated by energy-saving lamps at close range is greater than that of ordinary light bulbs? Recently, after some foreign media reported this, some citizens of our city began to pay attention to the use of energy-saving lamps. The reporter learned from relevant experts that energy-saving lamps will indeed produce electromagnetic radiation when used, but as long as they exceed a certain distance, the radiation will not cause harm to the human body.
Detection: The closer you are to the light bulb, the stronger the electromagnetic radiation
Recently, in a program broadcast by a TV station, environmental protection engineers have Nearly 10 different brands of energy-saving lamps purchased through the channel were tested with professional instruments. The test results showed that in the office, the electromagnetic field level was about 1 volt/meter. Up to 380 volts/meter; when the instrument is 1.5 meters away from the energy-saving lamp, the value drops to a dozen volts. Other brands of energy-saving lamps, the short-range electromagnetic radiation value is also more than 200 volts / meter.
According to the current “Regulations of the People’s Republic of China on Electromagnetic Radiation Protection”, the electromagnetic radiation value of public safety lighting equipment should be within 40 volts/meter, and the radiation data measured by these energy-saving lamps at close range exceeds the safe value. . Whether energy-saving lamps are safe and how to use them has become a matter of public concern.
Experts: When using, do not get too “close”
It is reported that excessive electromagnetic radiation can cause headaches, insomnia, dreams, and physical loss However, Xiang Yuanyi, a senior engineer at the Radiation Environment Monitoring Technology Center of the Ministry of Environmental Protection who participated in the test, said: “As long as energy-saving lamps are used reasonably, they are beneficial to people and not harmful. ” He said that electromagnetic radiation exists in our lives, and the human body has a certain tolerance to it. If you don’t use energy-saving lamps continuously for a long time, there is no harm to your health.
Yang Shuqiang, a lecturer at the School of Physics and Electronic Information, Luoyang Normal University, has done research on LED light sources. He said that the working principle of energy-saving lamps is to use electronic ballasts to generate high-frequency oscillations to stimulate internal materials to light up, so it is bound to generate electromagnetic radiation. At close range, the electromagnetic radiation produced by energy-saving lamps is indeed stronger than incandescent lamps or old-fashioned fluorescent lamps, but as long as they are at a certain distance, the electromagnetic radiation of energy-saving lamps will become very weak. In addition, the environmental protection performance of energy-saving lamps with less power consumption and long life is suitable for promotion.
A staff member of the Resource Conservation and Environmental Protection Section of the Municipal Development and Reform Commission said that the energy-saving lamps promoted by the state have passed the safety inspection and meet the safety standards. If they are used correctly, they will not cause harm to the human body.
Yang Shuqiang said that when using energy-saving lamps, the light source is generally more than 1 meter away from people. Energy-saving lamps are safe to use as basic lighting sources, but it is best not to use them as beds Use for headlamps and desk lamps. As long as it is not “intimate” contact, there is no need to worry about its radiation exceeding the standard and harmful to health.
Relevant experts call on manufacturers of energy-saving lamps to mark the electromagnetic radiation intensity of their products, including safe distance and recommended use time.
