Part 1: General requirements and white colour grid

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 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 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 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 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 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) 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 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 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 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 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 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 62707-1 has been prepared by subcommittee 34A: Lamps, of IEC
technical committee 34: Lamps and related equipment.
The text of this standard 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.
This 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 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,
• replaced by a revised edition, or
• amended.
IMPORTANT – The “colour inside” logo on the cover 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.

LED-BINNING –
Part 1: General requirements and white colour grid

1 Scope
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/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 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 references
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.
