22、rotechnical 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 the electrical and electronic fields.
23、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 entrusted to technical committees; any IEC Nat
24、ional 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 International Organization for Standardization (
25、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 technical committee has representation
26、 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 Publications is accurate, IEC cannot b
27、e 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 their national and regional publications. A
28、ny 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 assessment services and, in some areas, access
29、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, employees, servants or agents including individ
30、ual 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 publication, use of, or reliance upon, th
31、is 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 possibility that some of the elements of th
32、is 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 62707-1 has been prepared by subcommittee 34A: Lamps, of IEC technical committee 34: Lamps and related equipment. The text of this stand
33、ard is based on the following documents: FDIS Report on voting 34A/1702/FDIS 34A/1736/RVD 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 first edition cancels and replaces IEC/PAS 62707-1, published in 2011. Th
34、is publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 4 62707-1 IEC:2013 A list of all parts in the IEC 62707 series, published under the general title LED-binning, can be found on the IEC website. The committee has decided that the contents of this publication will rema
35、in 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, replaced by a revised edition, or amended. IMPORTANT The “colour inside” logo on the cover
36、page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this publication using a colour printer. 62707-1 IEC:2013 5 LED-BINNING Part 1: General requirements and white colour grid 1 Scope
37、 This part of IEC 62707 specifies general requirements, a grid and a corresponding code for the colour binning of white LED packages emitting incoherent, visible radiation. It applies for LED packages. Other parts of the IEC 62707 series covering chromaticity of coloured LED packages, luminous flux/
38、luminous intensity, colour rendering and forward voltage are in preparation or under consideration. NOTE 1 This International Standard does not apply for LED modules, LED lamps and LED luminaires. NOTE 2 Even though the words “white light“ are used, the purpose of this International Standard is not
39、to define “white light“, but to specify a grid and a corresponding colour code for the colour binning of white LED packages emitting incoherent, visible radiation. The area covered by the grid may differ from the definition of white light given in other standards or regulations. 2 Normative referenc
40、es The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC/
41、TS 62504, General lighting LEDs and LED modules Terms and definitions 3 Terms and Definitions For the purposes of this document, the terms and definitions given in IEC/TS 62504, as well as the following apply. 3.1 bin restricted range of LED package performance characteristics used to delimit a subs
42、et of LED packages near a nominal LED package performance as identified by chromaticity, photometric performance and forward voltage 3.2 grid entity representing colour coordinates and specified by a set of grid points 3.3 grid point colour coordinate in u, v colour space (or its equivalent in the x
43、, y colour space) identified by two discrete indices, the first index p counting steps along the Planckian locus, and its extension beyond the high temperature boundary towards blue colours and second index j along Judd isothermal lines Note 1 to entry: The u, v colour space is specified in ISO 1166
44、4-5 CIE S 014-5/E. The x, y colour space is specified in ISO 11664-1 CIE S 014-1/E. 6 62707-1 IEC:2013 3.4 white color bin area inside a quadrilateral defined by four grid points 4 Chromaticity bins for white LED packages 4.1 Grid for white LED packages The grid shall be aligned in equidistant steps
45、 along the Planckian locus, and its extension beyond the high temperature boundary towards blue colours, in the first direction (Planck-axis) and in equidistant steps along the Judd isothermal lines in the second direction (Judd-axis). The origin of the grid shall be on the Planckian locus at T(u/v)
46、 = (0,180 06/0,395 28). The distance between adjacent grid points along the Planckian locus and its extension beyond the high temperature boundary towards blue colours and along Judd isothermal lines in the u, v colour space shall be s = 0,001 74. Steps along the Planckian locus are counted with a p
47、ositive index p, steps toward blue with a negative index p. Steps towards the saturated colour line (gamut) along the Judd-axis are counted with a positive index j and with negative index j in the opposite direction. NOTE 1 s = 0,0017 4 has been chosen as providing for the best alignment with existi
48、ng chromaticity requirements. The Planckian locus shall be extended beyond T(towards blue) as follows (see Figure 1): Quadratic Bzier locus defined by three points: P1: T(u/v) = (0,180 06/0,395 28) P2: (u/v) = (0,141 22/0,155 93) P3: (u/v) = (0,256 80/0,016 59) The Bzier locus is B(t) = P1 (1-t)2+ 2
49、P2 t (1-t) + P3 t2; t (0;1). NOTE 2 P2is the intersection of spectral locus of the u, v colour space and tangent of Planckian locus at Tin direction of blue wavelength. NOTE 3 P3corresponds to a wavelength of 380 nm on the spectral locus of the u, v colour space. 62707-1 IEC:2013 7 0,55 0,50 0,45 0,40 0,35 0,30 0,25 0,20 0,15 0,10 0,05 0 0,1 0,2 0,3 0,4 0,5 0,6 7 000 K 12 000 K K
