INTRODUCTION
The first edition of a safety standard for LED modules for general lighting applications
acknowledges the need for relevant tests for this new source of electrical light, sometimes
called “solid state lighting”.
The provisions in the standard represent the technical knowledge of experts from the fields of
the semiconductor industry and those of the traditional electrical light sources.
Two types of LED modules are covered: with integral and external control gear.
LED MODULES FOR GENERAL LIGHTING –
SAFETY SPECIFICATIONS
1 Scope
This document specifies general and safety requirements for light-emitting diode (LED)
modules:
• non-integrated LED modules without integral control gear (LEDni modules) and semi-
integrated LED modules (LEDsi modules) for operation under constant voltage, constant
current or constant power;
• self-ballasted Integrated LED modules (LEDi modules) for use on DC supplies up to 250 V
or AC supplies up to 1 000 V at 50 Hz or 60 Hz.
LED modules within the scope of this document can be integral, built-in or independent.
This document is not applicable for LED lamps.
NOTE 1 The safety requirements for separate control gear are specified in IEC 61347-2-13. The performance
requirements for separate control gear LED modules are specified in IEC 62384 IEC 62717.
NOTE 2 Requirements for LED modules with integrated control gear and equipped with a lamp cap (self-ballasted
lamp), intended for mains voltage general lighting service retrofit applications (thereby replacing existing lamps
with identical lamp caps) are specified in IEC 60968 (an amendment to the present edition or a new edition with
extended scope is in preparation).
Requirements for LED modules with integrated control gear and equipped with a lamp cap (self-ballasted lamp),
intended for non-mains voltage general lighting service retrofit applications (thereby replacing existing lamps with
identical lamp caps) are under consideration.
NOTE 3 Where in the requirements of this standard both types of LED modules, with and without integral control
gear, are addressed, the word “modules” is used instead. Where only the expression “LED module(s)” is used, it is
understood to refer to the type without integral control gear.

4 General requirements
4.1 LED modules shall be so designed and constructed that in normal use they operate
without danger to the user or surroundings when used as intended (see manufacturer’s
instructions).
NOTE IEC 61347-1:2015, Annex S gives examples of insulation coordination which can be appropriate for LED
modules.
4.2 LED modules shall be classified, according to the method of installation, as:
– built-in,
– independent, or
– integral.
4.3 For non-integrated LED modules and semi-integrated LED modules, all electrical
measurements, unless otherwise specified, shall be carried out at voltage limits (min/max),
current limits (min/max) or power limits (min/max) and minimum frequency, in a draught-free
room at the temperature limits of the allowed range specified by the manufacturer. Unless the
manufacturer indicates the most critical combination, all combinations (min/max) of
voltage/current/power and temperature shall be tested.
4.4 For self-ballasted integrated LED modules, the electrical measurements shall be
carried out at the tolerance limit values of the marked rated supply voltage.
4.5 Integral LED modules not having their own enclosure shall be treated regarded as
integral components of luminaires according to IEC 60598-1:2014, 0.5.1. They shall be tested
assembled in the luminaire, and as far as applicable with the present standard.
4.6 In addition to the requirements of this document, independent LED modules shall
comply with IEC 60598-1:2014 and IEC 60598-1:2014/AMD1:2017, where these requirements
are not already covered in this standard.
4.7 If the LED module is a factory sealed unit, it shall not be opened for any tests. In case
of doubt based on the inspection of the LED module and the examination of the circuit
diagram, and in agreement with the manufacturer or responsible vendor, such specially
prepared LED modules shall be submitted for testing so that a fault condition can be
simulated.
4.8 For LED modules with integrated controlgear providing SELV, the requirements
according to IEC 61347-1:2015 and IEC 61347-1:2015/AMD1:2017, Clauses L.5, L.6, L.7, L.8,
L.9, L.10, and L.11 apply.
5 General test requirements
5.1 Tests according to this document shall be type tests.
NOTE The requirements and tolerances permitted by in this document are related to testing of a type-test sample
submitted by the manufacturer for that purpose. Compliance of the type-test sample does not ensure compliance of
the whole production of a manufacturer with this safety standard.
Conformity of production is the responsibility of the manufacturer and may can need routine tests and quality
assurance in addition to type testing.
5.2 Unless otherwise specified, The tests shall be carried out at an ambient temperature of
10 °C to 30 °C. If the manufacturer specifies a different ambient termperature, this shall be
used as test temperature.
5.3 Unless otherwise specified, the type test shall be carried out on one sample consisting
of one or more items submitted for the purpose of the type test.
In general, all tests shall be carried out on each type of LED module or, where a range of
similar LED modules is involved, for each wattage power in the range or on a representative
selection from the range, as agreed with the manufacturer.
5.4 If the light output has detectably substantially changed, the LED module shall not be
used for further tests.
NOTE Usually, a value of 50 % indicates irreversible changes in the LED module.
5.5 For SELV-operated LED modules, the requirements of IEC 61347-2-13, Annex I, apply
additionally.
General conditions for tests are given in Annex A.
Testing of integral LED modules not having their own enclosure shall be done as part of the
luminaire as far as applicable.
6 Classification
Modules are classified, according to the method of installation, as:
– built-in;
– independent;
– integral.
For integral modules, the NOTE to 1.2.1 in IEC 60598-1 applies.

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 62031 has been prepared by subcommittee 34A: Lamps, of IEC
technical committee 34: Lamps and related equipment.
This second edition cancels and replaces the first edition published in 2008,
Amendment 1:2012 and Amendment 2:2014. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) the scope was clarified as well as the wording in several other clauses;
b) the normative references were updated;
c) the definitions for "replaceable LED module", "non-replaceable LED module" and "non-
user replaceable LED module" were introduced while other definitions covered by
IEC 62504 have been removed;
d) the marking clause was restructured and a table added to provide an informative overview;
e) the marking requirements for built-in LED modules were changed;
f) the entry for the marking with the working voltage was revised;
g) the provisions for terminals and heat management were revised;
h) Annex B was deleted;
i) information for luminaire design with regard to working voltage and water contact was
introduced;
j) an abnormal temperature test was introduced.
The text of this International Standard is based on the following documents:

IEC 61347-1:2015/AMD1:2017, Clause 14 and the test according to 12.2.
12.2 Overpower condition
The test conditions according to Annex A apply.
The LED module shall be switched on and the power monitored (at the input side). The
voltage or the current shall be increased until 150 % of the rated power is reached. The test
shall be continued until the LED module is thermally stabilized. A stable condition is reached
if the temperature does not change by more than 5 K in 1 h. The temperature shall be
– 14 – IEC 62031:2018 © IEC 2018
measured in the t point. The LED module shall withstand the overpower condition for at least
c
15 min, the time period which can lie within the stabilization period if the temperature change
is ≤ 5 K.
If the LED module contains an automatic protective device or circuit which limits the power, it
is subjected to a 15 min operation at this limit. If the device or circuit effectively limits the
power over this period, the LED module has passed the test, provided that compliance to 4.1
and the last paragraph of 12.2 is fulfilled.
After finalizing the overpower mode, the LED module is operated under normal conditions
until thermally stable.
For the purpose of this test, "operated" means that the LED module is supplied with the rated
input current or rated input voltage. The LED module does not need to emit light.
The test is considered as passed if no fire, smoke or flammable gas is produced and if the
15 min overpower condition has been withstood. To check whether molten material might
present a safety hazard, a wrapping tissue according to ISO 4046-4:2016, 4.215, spread
below the LED module shall not ignite.

keeping the temperature below the rated maximum temperature t . It is applicable for
c
replaceable LED modules except for non-user replaceable LED modules.
20.2 Thermal interface material
For the purpose of heat-transfer from the LED module to the luminaire, the use of thermal
interface material can be necessary. Any thermal interface material shall be delivered within
the LED module packaging.
20.3 Heat protection
LED modules shall not impair safety when operated under poor heat-conduction conditions.
Compliance is checked by the test specified in Annex D.
21 Photobiological safety
21.1 UV radiation
The ultraviolet hazard efficacy of luminous radiation of an LED module shall not exceed
2 mW/klm.
Compliance is checked by measurement of the spectral power distribution and subsequent
calculation of the ultraviolet hazard efficacy of luminous radiation according to
IEC 62471:2006, Clause 5.
LED modules not relying on the conversion of UV radiation are expected to not exceed the
maximum allowed ultraviolet hazard efficacy of luminous radiation. They do not require
measurement.
21.2 Blue light hazard
For the assessment of the blue light hazard IEC TR 62778:2014 shall be applied. The
Technical Report shall be regarded as normative.
NOTE IEC TR 62778:2014, Clause C.2 gives a method to classify LED modules where full spectral data is not
available.
21.3 Infrared radiation
LED modules are expected to not reach a level of infrared radiation where marking or other
safety measures are required. They do not require measurement.

Annex A
(normative)
Test conditions
IEC 61347-1:2015, Clauses H.1, H.2, H.4, H.7, H.8, and H.11 apply. In H.1.3, the first
paragraph shall be ignored. In all clauses, “lamp”, “(lamp) control gear” and “ballast” shall be
replaced with “LED module”.
Annex B
(informative)
Conformity testing during manufacture
This test is carried out at 100 % of production. It is combined with the measurement of input
power at rated voltage/current. The luminous flux of no LED module should be significantly
lower than that of the rest of the production.
NOTE Very low values of the luminous flux indicate internal losses that can be safety relevant, such as current
bridges.
For independent and built-in LED modules, IEC 60598-1:2014, Annex Q is applicable, but
without the polarity check.

Annex C
(informative)
Information for luminaire design
C.1 Heat management
C.1.1 General
Clause C.1 applies for LED modules that rely on heat-conduction to the luminaire for safe
operation.
Annex C covers only those provisions that are related to the thermal needs specific for these
LED modules.
NOTE Because of their non-interchangeability, integral LED modules are excluded. Because independent LED
modules are luminaire-like, not needing protection or else from a luminaire neither using a lampholder, they
provide for their own heat management and are excluded. Only built-in LED modules remain within the scope of
Annex C.
For safe operation of these LED modules, it is essential to observe the recommendations of
Annex C.
