18、d Electronic Manufacturers Association FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all ques
19、tions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication
20、(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC col
21、laborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion
22、 on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensu
23、re that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to
24、 the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certificatio
25、n bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall atta
26、ch to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees
27、) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publicatio
28、n. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. However
29、, a technical committee may propose the publication of a technical report when it has collected data of a different kind from that which is normally published as an International Standard, for example “state of the art“. IEC/TR 62493-1, which is a technical report, has been prepared by IEC technical
30、 committee 34: Lamps and related equipment. 4 TR 62493-1 IEC:2013(E) The text of this technical report is based on the following documents: Enquiry draft Report on voting 34/178/DTR 34/183/RVC Full information on the voting for the approval of this technical report can be found in the report on voti
31、ng indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts in the IEC 62493 series, published under the general title Assessment of lighting equipment related to human exposure to electromagnetic fields can be found o
32、n the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn,
33、 replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date.

TR 62493-1 IEC:2013(E) 5 INTRODUCTION In 2011 it was decided by VDE and ZVEI to start a measurement campaign for testing a broad range of different types of luminaires with different lamp technologies against the new EMF (Electroma
35、gnetic Fields) standard IEC 62493:2009 (identical to EN 62493:2010-02). The goal was to get an overview on the EMF measurement results dependent on different lamp technologies used in current luminaires on the market. For this measurement campaign only the test procedure with the so called Van der H
36、oofden head in the frequency range from 20 kHz to 10 MHz was used. The goal of this campaign is to identify construction details of lighting equipment which are critical for the EMF measurements. NOTE The VDE Testing and Certification Institute is a part of the VDE Association for Electrical, Electr
37、onic & Information Technologies. The VDE Testing and Certification Institute is accredited on a national and international level for the area of testing and certification of electrotechnical equipment, components and systems. ZVEI is the German Industry Association for the Electrical Industry. 6 TR

39、 62493 series presents an overview on EMF measurement results dependent on different lamp technologies used in current luminaires. For the measurement only the test procedure with the so called Van der Hoofden head in the frequency range from 20 kHz to 10 MHz was used. 2 Normative references The fol

41、, Assessment of lighting equipment related to human exposure to electromagnetic fields 3 Test procedure The testing of luminaires has been performed according to the requirements of IEC 62493:2009. The luminaires have been placed over the test head at the distance d as required by the standard. Figu
42、re 1 shows the set-up in principal.

43、h measurement over the frequency range from 20 kHz to 10 MHz is a single value F which is calculated using all measurement values in the whole frequency range. For this calculation the measured voltages, weighted with the limit at each frequency, are summed up over the whole frequency range. The lim
44、it for F is a value of 0,85. The noise level, caused by the thermal noise floor in the receiver is always present even if the luminaire under test is not energized. The value F of this noise level in our case is 0,03. The noise level is dependent on the overall noise figure of the receiver and the a
45、ttenuator setting of the receiver. If the receiver is set to higher attenuations then the noise level is higher and therefore the noise level result F is higher also. 4 Presentation of results 4.1 General In the following subclauses the results of the measurement campaign are presented as tables sho
46、wing the influence of different parameters of the tested luminaires. 4.2 Frequency distribution of the measured values The frequency distribution figures show the number of luminaires for which measurement results (Factor F) are within a result interval. It is recognized that there is a clustering w
47、ithin some intervals. 8 TR 62493-1 IEC:2013(E) Measurement value according to IEC 62493 (Van der Hoofden head) IEC 1681/13 Figure 2 Frequency distribution of the measured values of the luminaires (absolute number of luminaires) Measurement value according to IEC 62493 (Van der Hoofden head) IEC 1682
48、/13 Figure 3 Frequency distribution of the measured values F in the interval from 0 to 0,85 expressed as percentage values. It is clearly visible in Figure 2 and Figure 3 that a number of 131 luminaires (81 %) out of a total of 161 (= 100 %) generated measurement values between 0 and 0,1. Only 16 lu
49、minaires (10 %) are in the range from 0,1 to 0,2. None of the measured luminaires are in the range between 0,4 and 0,85. Only one luminaire has shown a result which is near to the limit of 0,85. It will be explained later why this special luminaire generated such a high result F. A significant majority (99 %) of all measured values are below half (0,425) of the limit (0,85).
