Lighting products for the European Union also made EMF requirements, CEN has published EN 62493: 2010 - Assessment of lighting equipment related to human exposure to electromagnetic fields. In the future, lighting products applying CE / GS / Bauart Geprüft certification must be evaluated when EN 62493. EN 62493: 2010 has entered a transition period. In the February 26, 2012 bulletin issued by OJ (OJ C 061 of 29/02/2012) to EN 62493: 2010 harmonized standards included in the list of LVD directive, its implementation date is February 1, 2013. EMF electromagnetic radiation on demand and requirements. Studies have shown that human long-term high-dose electromagnetic radiation environment, resulting in more serious neurasthenia syndrome, such as headache, vomiting, dizziness, fatigue and discomfort, reduced memory and some potential biological damage, harm to human health bond. So in the lighting field, for the protection of the central nervous system tissue exposed to these human head and torso, to be a reasonable method of evaluation of lighting in the surrounding space electromagnetic fields created. To this end, the EU proposed EMF lighting products for the requirements of 1 November 2010, CEN issued a decision on the lighting equipment related to human electromagnetic exposure assessment standard EN 62493: 2010. The standard lamps proposed assessment body's electromagnetic radiation requirements, the need standards set forth in the assessment of EMF illuminating device comprising: the lighting for the purpose of generating and distributing light having the basic functions, and intended to be connected to the low voltage power supply network or All indoor and outdoor lighting equipment with battery-operated; general lighting equipment; One of the main features is a multifunctional device for illumination and independent accessory lighting devices these four categories of products. To this end, inspection and quarantine departments to remind the relevant lighting manufacturers, while exports to the EU in preparation to do the following: First, focus on the new standards, the product according to the new standards were sent to a qualified laboratory testing and certification, to ensure that products meet the electromagnetic radiation standards; Second, enterprises should readjust the product design structure, the use of key electronic components to assess, configure related test equipment, and strengthen their own quality control system; Third, enterprises should pay attention to new trends in EU directives and regulations, to update the relevant Information, Technical Barriers to avoid causing loss of control resulting in product quality foreign communications, export returns, trade claims and so on. EN62493 standard concerning the product used for lighting purposes, with the generation and distribution of the light basic functions, and intended to be connected to the low voltage power supply network or all indoor and outdoor lighting equipment with battery-operated; general lighting equipment refers to all industrial, residential, public spaces and street lighting; lighting unit is one of the main functions of the multifunction device EN62493 standard lighting products and exclusive use of aircraft and airport lighting equipment; and lighting equipment for road vehicles (except public transport passenger compartment lighting equipment outside); agricultural lighting equipment; lighting equipment on board; copiers, projectors lighting equipment; with all kinds of appliances EMF clear requirements in other IEC standards; the list of all the internal parts of the lighting equipment is not this standard, such as: built-in electronic transformer , built-in electronic ballast ... EN62493 requirements in order to comply with this standard EMF EMF requirements, the need to meet all of the following requirements: 20 kHz - 30 MHz power terminal disturbance voltage Mains Terminal Disturbance Voltage 100 kHz - 30 MHz electromagnetic disturbance Radiated Electromagnetic Radiation Disturbance 30 MHz - 300 MHz radiated electromagnetic disturbance Radiated Electromagnetic Disturbance 20 kHz - 10 MHz induced current density (Induced Current Density
