31、ctrotechnical committees (IEC National Committees). The object of IEC is to promote international 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 Specif
32、ications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter 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. Internati
33、onal, governmental and non- governmental organizations liaising with the IEC also participate 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
34、 decisions or agreements of IEC on technical matters express, as nearly as possible, an international 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
35、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 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)
36、In order to promote international uniformity, IEC National Committees undertake to apply 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
37、be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. 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 certific
38、ation 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, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury
39、, 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 publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cit
40、ed in this publication. Use of the referenced publications is indispensable for the correct 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 identifyi
41、ng any or all such patent rights. International Standard IEC 62756-1 has been prepared by subcommittee 34C: Auxiliaries for lamps, of IEC technical committee 34: Lamps and related equipment. The text of this standard is based on the following documents: CDV Report on voting 34C/1054/CDV 34C/1081B/RV
42、C Full information 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. A list of all parts in the IEC 62756 series, published under the general title Di
43、gital load side transmission lighting control (DLT), can be found on the IEC website. 6 IEC 62756-1:2015 IEC 2015 The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data rela
44、ted to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. IMPORTANT The colour inside logo on the cover page of this publication indicates that it co
45、ntains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. IEC 62756-1:2015 IEC 2015 7 INTRODUCTION This standard concerning Digital Load Side Transmission Lighting Control (DLT) describes a proto
46、col for simple control of brightness, colour, colour temperature, and other parameters for the purpose of controlling lighting sources such as CFLi, LED light engines, electronic control gear and any other light source with integrated or external control gear. This protocol uses existing wiring and
47、allows easy retrofit of standard switches, dimmers and lamps with the new devices described in this standard, with little or no configuration. The following standards contain safety requirements for control devices and control gear: IEC 60669-2-1, Switches for household and similar fixed electrical
48、installations Part 2-1: Particular requirements Electronic switches, IEC 61347, Lamp control gear, IEC 60968, Self-ballasted lamps for general lighting services Safety requirements, IEC 62560, Self-ballasted LED-lamps for general lighting services by voltage 50 V Safety specifications. 8 IEC 62756-1
