Radiation standard depth analysis of self ballasted fluorescent lamps for general lighting applications

Internationally, "energy-saving lamp products in addition to the implementation of CISPR15, the impact on the human body into the scope of examination, IEC was established in 2009" IEC62493:2009 lighting equipment for the electromagnetic radiation on the human body evaluation ", the standard for measuring the lighting equipment surrounding the space electromagnetic field to determine the evaluation method and standard working conditions and the appropriate distance measurement. The European Union has increased the international standard to the low voltage directive (LVD). Recently, self ballasted fluorescent lamps for general lighting (commonly known as the "energy-saving lamps") radiation products has become a hot topic of common concern of the public and the lighting industry practitioners, China is the "energy-saving lamps" use and export country, China's "energy saving lamp" products have no radiation standard international "radiation? The standards of energy-saving lamps products is?" how the actual real situation of energy-saving lamp radiation? Radiation standard at home and abroad "energy-saving lamps" in addition to product safety and performance requirements, the "energy-saving lamps" products and electromagnetic compatibility requirements, China's implementation of the standard GB17743-2007 "radio disturbance characteristics of electrical lighting and similar equipment to the limits and methods of measurement", GB17743-2007 is the equivalent of the International Electrotechnical Commission (IEC) Special Committee on radio interference CISPR15:2005+A1:2006, radio frequency disturbance including radiation and conduction, 9kHz~300MH Radiated electromagnetic disturbance in Z frequency range.

Energy saving products, such as energy-saving certification testing has been GB17743-2007 as one of the criteria to be assessed. Internationally, "energy-saving lamp products in addition to the implementation of CISPR15, the impact on the human body into the scope of examination, IEC was established in 2009" IEC62493:2009 lighting equipment for the electromagnetic radiation on the human body evaluation ", the standard for measuring the lighting equipment surrounding the space electromagnetic field to determine the evaluation method and standard working conditions and the appropriate distance measurement.

The European Union has increased the international standard to the low voltage directive (LVD), from February 2013, lighting equipment exports to Europe, should meet the requirements of this standard.

The National Standardization Technical Committee is lighting the formulation of national standards "lighting equipment for the electromagnetic radiation on the human body evaluation", it is equivalent to IEC62493:2009, currently in the draft stage, it includes the evaluation of energy-saving lamps on the electromagnetic radiation on the human body.

"IEC62493:2009 lighting equipment for the electromagnetic radiation on the human body evaluation" of "energy-saving lamps" and other provisions - Measurement of distance measuring distance IEC62493:2009 "lighting equipment for the electromagnetic radiation on the human body evaluation" for different lighting products provide different distance measurement. For general lighting with self ballasted fluorescent lamps (commonly known as "energy-saving lamps") the measuring distance is 30cm.

EC62493:2009 standard for measuring devices (conductive ball, protective network, receiver) and its layout is clearly defined. The use of "energy saving lamp" is different from that used by the ear. The measuring distance cannot be 0. According to this standard, measurement of a 12W energy saving lamp ", and analyzed by Jcap/Jlim, Jcap said the current density for electric field, Jlim said the current density of the basic limit, the standard limit requirements for 0.85 Jcap/Jlim. When the measuring distance is 0, Jcap/Jlim=0.9737 (see Figure 1); when the measuring distance is 30cm, Jcap/Jlim=0. 0864 (see Figure 2); when the distance is 50cm, Jcap/Jlim=0.0504 (see Figure 3).

The measurement distance is 0, but Jcap/Jlim=0.9737>0.85, 30cm, Jcap/Jlim=0.0864<0.85, 30cm according to the measured value of the product is qualified, and determine if the error will measure the distance less than 30cm value judgement, the unqualified products will become.

Therefore, the size of the radiation energy saving lamp with the distance and have a great relationship, in actual use, the body usually distance lighting is not 0, generally have a certain distance, this is the standard 30cm for reasons of distance testing, and testing institutions of scientific testing and judging guidelines should be followed.
