GENERAL LIGHTING – LIGHT EMITTING DIODE (LED) PRODUCTS
AND RELATED EQUIPMENT – TERMS AND DEFINITIONS
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 62504 has been prepared by IEC technical committee 34: Lamps
and related equipment in collaboration with representatives from CIE.
This first edition cancels and replaces the IEC TS 62504 published in 2011.
The significant changes with respect to IEC TS 62504 are as follows:
a) Terms from the International Electrotechnical Vocabulary that have not been modified are
deleted.
b) Alignment with the CIE has been done.
c) An introduction has been added

INTRODUCTION
0.1 Principles of this International Standard
This document is based on IEC TS 62504:2011, General Lighting – LEDs and LED modules –
Terms and definitions, which was under the responsibility of SC 34A but this revision as
International Standard IEC 62504 transfers responsibility to TC 34.
The objective of this introduction is to help the reader to understand which terms are included
and to have an understanding of the LED product overview.
Compared with IEC TS 62504, the main changes are as follows.
0.2 Terms to include
General lighting terms in IEC 60050-845:1987, International Electrotechnical Vocabulary that
have not been modified will not be included in this standard.
Alignment with CIE is done. IEC will be the reference for products and related equipment and
CIE for lighting terminology. Alignment with ANSI RP16-10, Chapter 6.8 was also considered.
The terms included are as far as possible used in LED standards and manufacturers'
literature.,
Process to update IEC 60050-845:1987, the International Electrotechnical Vocabulary for
definitions that will be considered as relevant is underway in IEC TC34.
0.3 Alphabetic sequence
In order to find the term in a logical sequence, we have grouped similar terms of a product,
example:
LED lamp
– integrated LED lamp ,
– non-integrated LED lamp .
For each term, reference is made to the relevant standard if appropriate.
0.4 LED product tree:
The sequence from the first component, the LED die up to the LED luminaire is drawn.
The term LED does not represent a product, so no technical data can be linked to the term
LED.

for a given evaluation location of the retinal hazard, the real or virtual object that forms the
smallest possible retinal image (considering the accommodation range of the human eye)
Note 1 to entry: The accommodation range of the eye is assumed to be variable from 100 mm to infinity. The
location of the apparent source for a given viewing position in the beam is that location to which the eye
accommodates to produce the most hazardous retinal irradiance condition.
Note 2 to entry: This definition is used to determine, for a given evaluation position, the location of the apparent
origin of laser radiation in the wavelength range of 380 nm to 1 400 nm. In the limit of vanishing divergence, i.e. in
the case of a well collimated beam, the location of the apparent source goes to infinity.
[SOURCE: IEC 60825-1, 3.10, modified – In the note 2 to entry the value of the wavelength
range is changed from '400 nm to 1 400 nm' to '380 nm to 1 400 nm'.]

lines pass through the centre of the front face of the lamp and through points at which the
luminous intensity is 50 % of the centre beam intensity
Note 1 to entry: Beam angle is expressed in degrees ( ° ).
Note 2 to entry: This angle is a full angle measure, not a half angle measure.
[SOURCE: IEC TR 61341, 2.4, modified, – The notes to entry are added.]
3.5
bin
restricted range of LED performance characteristics used to delimit a subset of LED dies or
LED packages near a nominal LED performance as identified by chromaticity, photometric,
radiometric and/or electrical characteristics
3.6 controlgear
3.6.1
controlgear for LED module

unit inserted between the electrical supply and one or more LED modules, which serves to
supply the LED module(s) with its (their) rated voltage or rated current, and may consist of
one or more separate components and may include means for dimming, correcting the power
factor and suppressing radio interference, and further control functions
Note 1 to entry: The controlgear consists of a power supply and a control unit.
Note 2 to entry: The controlgear may be partly or totally integrated in the LED module.
Note 3 to entry: When no confusion is expected like when used in a LED standard for example, “controlgear” may
also be used. Both terms “controlgear” or “control gear” are acceptable.
[SOURCE: IEC 61347-2-13, 3.1, modified – The word 'electronic' is deleted from the term and
the words “further control functions” and the notes to entry are added.]
3.6.2
power supply of the controlgear
electronic device, being part of the controlgear, capable of controlling current, voltage or
power within design limits, containing no additional LED control capabilities
---------------------- Page: 13 ----------------------
SIST EN 62504:2014
– 8 – IEC 62504:2014 © IEC 2014
Note 1 to entry: For LEDsi modules, the power supply of the controlgear is separate from the LED module on a
distant location.
Note 2 to entry: The energy source of a power supply can be either a battery or the electrical supply system.
3.6.3
control unit of the controlgear
electronic device, being part of the controlgear, responsible for controlling the electrical
energy to the LED light sources as well as colour mixing, response to depreciating luminous
flux and further performance features
Note 1 to entry: In LEDsi modules, the control unit of the controlgear is on board of the LED module and separate
from the power supply of the controlgear.
3.7
dominant wavelength
λ
d
wavelength of the monochromatic stimulus that, when additively mixed in suitable proportions
with the specified achromatic stimulus, matches the colour stimulus considered in the
CIE 1931 x,y chromaticity diagram
Note 1 to entry: Dominant wavelength is expressed in nanometres (nm).
Note 2 to entry: In the case of purple stimuli, the dominant wavelength is replaced by the complementary
wavelength.
Note 3 to entry: For characterising LED light sources the reference achromatic stimulus should be illuminant E
which has the chromaticity coordinates x = 0,3333, y = 0,3333.
E E
Note 4 to entry: A value for dominant wavelength should only be stated for LED light sources emitting coloured
light. For LED light sources emitting white light no meaningful value for dominant wavelength can be given.
Note 5 to entry: Figure 12 in CIE 127:2007 shows the relationship between chromaticity coordinate C of LED light
sources and value of dominant wavelength D. N is the chromaticity coordinate of achromatic stimulus E.
Note 6 to entry: Deviating from the peak wavelength, the dominant wavelength determines perceived colour.
[SOURCE: IEC 60050-845:1987, 845.03.44, modified – The words 'in the CIE 1931 x,y
chromaticity diagram' and the notes to entry 3 to 6 have been added; CIE S 017/E:2011, 17-
