22、d.c. or a.c. supplied electronic step-down convertors for filament lamps 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 inte
23、rnational co-operation on all questions 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 (hereaft
24、er referred to as “IEC Publication(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 partici
25、pate in this preparation. IEC collaborates 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 i
26、nternational consensus of opinion 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 re
27、asonable efforts are made to ensure 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
28、IEC Publications transparently to 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 con
29、formity. Independent certification 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 public
30、ation. 7) No liability shall attach 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, o
31、r for costs (including legal fees) 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 corre
32、ct application of this publication. 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. International Standard IEC 61347-2-2 has been prepared
33、by subcommittee 34C: Auxiliaries for lamps, of IEC technical committee 34: Lamps and related equipment. This second edition of IEC 61347-2-2 replaces the first edition (2000), Amendment 1 (2005) and Amendment 2 (2006). The major modification for this second edition is the changeover from SELV equiva
34、lent to SELV. This standard shall be used in conjunction with the second edition of IEC 61347-1 (2007) and its Amendment 1 (2010) and 2 (to be published). 4 61347-2-2 IEC:2011 The text of this standard is based on the following documents: FDIS Report on voting 34C/994/FDIS 34C/1001/RVD Full informat
35、ion on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This part 2 supplements or modifies the clauses in IEC 61347-1, so as to convert that publicatio
36、n into the IEC Standard: Particular requirements for d.c. or a.c. supplied electronic step-down convertors for filament lamps. NOTE In this standard, the following print types are used: Requirements proper: in roman type. Test specifications: in italic type. Explanatory matter: in smaller roman type
37、. A list of all parts of the IEC 61347 series, under the general title: Lamp control gear can be found on 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
38、 data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 61347-2-2 IEC:2011 5 INTRODUCTION This second edition of IEC 61347-2-2 is published in conjunction with IEC 61347-1. The formatting into separately publ
39、ished parts provides for ease of future amendments and revisions. Additional requirements will be added as and when a need for them is recognized. This standard, and the other parts which make up IEC 61347-2, in referring to any of the clauses of IEC 61347-1, specify the extent to which such a claus
40、e is applicable and the order in which the tests are to be performed; they also include additional requirements, as necessary. All parts which make up IEC 61347-2 are self-contained and, therefore, do not include references to each other. Where the requirements of any of the clauses of IEC 61347-1 a
41、re referred to in this standard by the phrase “The requirements of clause n of IEC 61347-1 apply“, this phrase is interpreted as meaning that all requirements of the clause in question of part 1 apply, except any which are clearly inapplicable to the specific type of lamp control gear covered by thi
42、s particular part of IEC 61347-2. 6 61347-2-2 IEC:2011 LAMP CONTROLGEAR Part 2-2: Particular requirements for d.c. or a.c. supplied electronic step-down convertors for filament lamps 1 Scope This part of IEC 61347 specifies particular safety requirements for electronic step-down convertors for use o
43、n d.c. supplies of up to 250 V or a.c. supplies of up to 1 000 V, at 50 Hz or 60 Hz and with rated output voltage 50 V r.m.s. at a frequency deviating from the supply frequency, or 120 V ripple free d.c. between conductors and between any conductor and earth, associated with tungsten-halogen lamps a
44、s specified in IEC 60357 and other filament lamps. NOTE The limit of 50 V rated output voltage is in accordance with band I of IEC 60449. Particular requirements for electronic step-down convertors with means of protection against overheating are given in Annex C. Particular additional requirements
45、for convertors providing safety extra low voltage (hereinafter SELV), are given in Annex I. Performance requirements are covered by IEC 61047. Plug-in convertors, being part of the luminaire, are covered as for built-in convertors by the additional requirements of the luminaire standard. 2 Normative
