25、ON 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 questions concerning standardization in

26、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(s)”). Their preparation is entruste

27、d 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 collaborates closely with the Internati

28、onal 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 on the relevant subjects since each

29、 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 ensure that the technical content of IEC

30、 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 the maximum extent possible in thei

31、r 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 certification bodies provide conformity assessme

32、nt 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 attach to IEC or its directors, employee

33、s, 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) and expenses arising out of the pu

34、blication, 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 publication. 9) Attention is drawn to the poss

35、ibility 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 63013 has been prepared by subcommittee 34A: Lamps, of IEC technical committee 34: Lamps and rela

36、ted equipment. The text of this International Standard is based on the following documents: FDIS Report on voting 34A/2008/FDIS 34A/2015/RVD Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above table. This document

37、 has been drafted in accordance with the ISO/IEC Directives, Part 2. 4 IEC 63013:2017 IEC 2017 The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific do

38、cument. At this date, the document will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IEC 63013:2017 IEC 2017 5 INTRODUCTION One of the benefits of LED lighting is their long lifetime compared to that of many other light source technologies. However, there is currently no int

39、ernational standard for predicting the long-term luminous flux maintenance of LED packages. This document is intended to close this gap by specifying methods for the long-term luminous flux maintenance projection. This document is the result of the discussions led by a special expert group within IE

40、C technical committee 34 on this topic. This expert group had collected a set of luminous flux maintenance measurements of 39 LED package types, each tested at three different temperatures. Various projection methods were analysed based on this set of test data. Regarding the selection of models, th

41、ere was a controversial discussion among the experts and no unanimous agreement could be found. It was concluded at the meeting in Berlin on 21 January 2014 to choose the TM-21 method as the starting point of the analysis and to have the border function as an alternative in case the TM-21 method was

42、 not applicable. It was further concluded that the Arrhenius temperature acceleration should be included in an informative annex. At the meeting on 26 January 2015 in Washington some further editorial improvements were made and it was agreed to submit this document to IEC as a new project with a vie

43、w to developing a full international standard. This new project was approved and all comments received during the enquiry stage were discussed by the project team and resolved. This document incorporates the changes agreed by the project team. 6 IEC 63013:2017 IEC 2017 LED PACKAGES LONG-TERM LUMINOU

44、S AND RADIANT FLUX MAINTENANCE PROJECTION 1 Scope This document is applicable to LED packages for general lighting services. It specifies procedures and conditions for measuring the luminous flux maintenance of LED packages. It also provides the procedures and conditions (criteria) of projecting the

45、 long-term luminous flux maintenance based on limited luminous flux maintenance test data collected. Within the context of this document, wherever luminous flux measurement data is specified, radiant flux measurement data can also be used. These projection methods employ data collected as per ANSI/I

46、ES LM-80-15 (LM-80). The long-term projection is based on the exponential-fit-function procedure of IES TM-21-11 (TM-21), and gives an alternative border function procedure in the case where the exponential-fit-function of IES TM-21-11 is not applicable. 2 Normative references The following document
