To the vast number of energy-saving lamps consumers an open letter

During the previous period, the "energy saving lamp radiation" obviously exceeded the rumors spread widely in the network, a lot of media reporters also follow the trend. Although the system followed by the quality inspection organization positive interviews and reports, and publicity in the media, largely reversed this false reports, but as a lighting professionals in the field, still feel that such things happen in the national science popularization work is still obviously insufficient therefore, through the media, to make a thorough and popular reports, let the people understand the characteristics of energy-saving lamp.

1, the general introduction of radiation

When it comes to radiation, we naturally think of the Fukushima nuclear power plant in Japan due to the earthquake and tsunami caused by nuclear leakage and nuclear radiation, so hear this term can not help but produce a nervous state of mind. In fact, modern life makes us full of radio waves. According to the common radio wave band can be divided into: working band of electronic ballast lighting; long wave, medium wave band, short wave band radio and television broadcasting; FM band band; mobile phone communication band; followed by the infrared band; visible light; ultraviolet band and higher frequency of X ray and gamma ray (note: light itself is a kind of radio waves, only shorter wavelength). These radio waves, will produce electromagnetic radiation, but only in some bands and a certain amount of radiation energy can pose a hazard to people's health. We must remember that SARS (SARS) spread period, there is a kindergarten to two 8 fluorescent lamps in the classroom chandelier lamp in the ultraviolet sterilization, disinfection of the classroom, but in the children entered the classroom, because the cleaners neglected the UV lamp is closed, resulting in widespread red children eyes. It can be seen that the original 8 lights fully visible light on the human eye has no effect, but only two UV lamps on the eyes of the children caused by swelling, which shows that the ultraviolet radiation than the visible light on the radiation damage is much greater. Similarly, in the radio band, lighting band, radiation on the human body injury radio and television and mobile phone band is much smaller, and X radiation with gamma ray energy on people's health damage is much greater.

As the general use of energy-saving lamps, the operating frequency of 30kHz ~ 50kHz, energy-saving lamps of the circuit, power and structure determines that it is almost impossible to produce an impact on human health hazards of electromagnetic radiation. This is my 10 years of national sampling, spot checks and a variety of product certification of thousands of batches of energy-saving lamp products in the test, has not seen the reasons for the excessive radiation examples. Someone may ask, since the energy-saving lamp radio radiation is so low, so the international standard IEC 62493, and promulgated the necessary implementation? You know, the IEC 62493 standard is the wireless radiation hazards restrictions on lighting electrical products all the developed market, if it is used rarely seen on "self ballasted electrodeless the fluorescent lamps" (and energy-saving lamp, also has a screw cap, screw can be conveniently used in lamp holder), because the work principle and frequency electrodeless lamp, resulting in the possibility of electromagnetic radiation exceed the standard is bigger, so the electrodeless fluorescent lamp, lighting is only recommended from the far public place for human body the road tunnel, etc., and can not be used for offices and homes, unless special measures are adopted.

2, the electric field in our life everywhere

In fact, in our modern world, the electric field is everywhere, all kinds of sounds very high voltage for example, we in the dry weather, in the hair coat, often heard "crackling discharge sound", in the dark environment can also see the spark discharge, the voltage induced discharge spark generated by at least. Thousands of volts to several thousand volts. In addition, because it is the role of friction electrification, we are in the dry weather, when the hands of running water pipes or different people encounter each other, often because of electrostatic discharge and the feeling of instant paralysis. When we are in the electrical laboratory, we do not touch any conductor in the body, and only the hand to touch the oscilloscope voltage probe, will be measured on the thousands of volts from the 50Hz grid induced voltage. But these do not constitute any harm to our health. It's like we know that flying faster stone more wounded people, but if one weighs only 0.1 grams of 100 grams of stone and a stone, with the same 10 meters / sec hit people, then 0.1 grams of the stone is not hurt, but 100 grams of stone will certainly hurt. The same example as well, we all know that the water temperature is higher the more people will burn, but if the water and a thermos of water is heated to 100 DEG C, so water is not to burn people, but a thermos of water will surely burn people, this is because the latter is more energy than the former.

3, the error analysis of false reports

Before a period of media reports, there are people on the basis of GB8702-88 "electromagnetic radiation protection regulations" in place strong instrument in measuring 10cm from energy-saving lamp 0 ~, the radiation field of up to 200 V / m, some as high as 1600 V / M (see the evening news in March 15th 08 edition A1 stack depth).

The main error of the result is:

(1) standard GB8702-88 standard for long wave, medium wave, short wave radio communications and power and the establishment of the launch site,: at the frequency of 0.1MHz~3MHz, is applicable and the radiation power is larger than 300W, and the total power of energy-saving lamp
