National foreword
This British Standard is the UK implementation of EN 62031:2008+A2:2015.

It is identical to IEC 62031:2008, incorporating amendment 1:2012 and
amendment 2:2015. It supersedes BS EN 62031:2008+A1:2013, which is
withdrawn.
The start and finish of text introduced or altered by amendment is indicated
in the text by tags. Tags indicating changes to IEC text carry the number
of the IEC amendment. For example, text altered by IEC amendment 1 is
indicated by .
The UK participation in its preparation was entrusted by Technical Committee
CPL/34, Lamps and Related Equipment, to Subcommittee CPL/34/1, Electric
lamps.
A list of organizations represented on this subcommittee can be obtained on
request to its secretary.
The publication does not purport to include all the necessary provisions of a
contract. Users are responsible for its correct application.
Compliance with a British Standard cannot confer immunity from
legal obligations.

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.

Terms and definitions

For the purposes of this document, the following terms and definitions apply.

For expressions and terms in the field of LEDs and LED modules, refer to IEC TS 62504,
which is currently in development.
3.1
light-emitting diode
LED
solid state device embodying a p-n junction, emitting optical radiation when excited by an
electric current
[IEV 845-04-40]
3.2
LED module
unit supplied as a light source. In addition to one or more LEDs, it may contain further
components, e.g. optical, mechanical, electrical and electronic, but excluding the control gear.
3.3
self-ballasted LED module
LED module, designed for connection to the supply voltage
NOTE

If the self-ballasted LED module is equipped with a lamp cap, it is regarded to be a self-ballasted lamp.

3.4
integral LED module
LED module, generally designed to form a non-replaceable part of a luminaire
3.5
integral self-ballasted LED module
self-ballasted LED module, generally designed to form a non-replaceable part of a luminaire
3.6
built-in LED module
LED module, generally designed to form a replaceable part built into a luminaire, a box, an
enclosure or the like and not intended to be mounted outside a luminaire, etc. without special
precautions

3.7
built-in self-ballasted LED module
self-ballasted LED module, generally designed to form a replaceable part built into a
luminaire, a box, an enclosure or the like and not intended to be mounted outside a luminaire,
etc. without special precautions
3.8
independent LED module
LED module, so designed that it can be mounted or placed separately from a luminaire, an
additional box or enclosure or the like. The independent LED module provides all the
necessary protection with regard to safety according to its classification and marking.
NOTE

The control gear must not necessarily be integrated in the module.

Conformity of production is the responsibility of the manufacturer and may 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.

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 module or, where a range of similar
modules is involved, for each wattage in the range or on a representative selection from the
range, as agreed with the manufacturer.
5.4

If the light output has detectably changed, the module shall not be used for further tests.

NOTE

Usually, a value of 50 % indicates irreversible changes in the 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.

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.

Information for luminaire design

D.1

General

This annex applies for LED modules that:
•

have a cap/base enabling the insertion and the withdrawal of the LED module with or
without the use of tools,

•

do not have a heat management on board and rather rely on heat-conduction to the
luminaire for safe operation.

This annex 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
this annex.

For safe operation of these LED modules, it is essential to observe the recommendations of
this annex.

Testing in the luminaire

The knowledge of t d and P d as provided by the LED module manufacturer, of the geometry
and the surface properties of the cap and of the t a of the luminaire to be designed, will allow
for designing a luminaire that will most probably keep the t c of the LED module. However,
testing in the luminaire if the luminaires does so will still be necessary.

Blue light hazard assessment
___________
LED modules of risk group 0 and risk group 1

If assessment according to IEC TR 62778 leads to risk group 0 or risk group 1 classification of

an LED module with respect to blue light hazard, any luminaire incorporating one or more of
these LED modules should also be classified as of the same risk group with respect to blue
light hazard, regardless of optics and viewing distance.
However, it should be left to the discretion of the luminaire manufacturer to apply
IEC TR 62778 directly to the luminaire, which could lead to a lower risk group classification.
D.4.2

LED modules with a threshold illuminance E thr

If assessment according to IEC TR 62778 leads to the classification of an LED module as
having a threshold illuminance E thr , any luminaire incorporating one or more of these LED
modules should be regarded classified as having the same threshold illuminance E thr . The
viewing distance where this threshold illuminance is reached should be calculated according
to 7.1 of IEC TR 62778 from the luminous flux distribution measurement of the luminaire.
However, it should be left to the discretion of the luminaire manufacturer to apply
IEC TR 62778 directly to the luminaire, which could lead to a threshold illuminance E thr
greater than that of the LED module.
NOTE If, apart from the light source and its components, luminaires incorporate passive optical components such
as lenses and reflectors, these will not change E thr .
