Overview

IEC 62722-2-1:2014 is an international standard published by the International Electrotechnical Commission (IEC) that specifies the performance requirements, test methods, and conditions for LED luminaires designed for general lighting purposes. This first edition replaces the earlier IEC PAS 62722-2-1 (2011) and introduces technical revisions to better align with related standards on LED modules and lighting performance.

Focused on LED luminaires using LED modules, this standard does not apply to luminaires with LED lamps or those intentionally producing colored light, nor does it cover OLED-based luminaires. It distinguishes between luminaires using LED modules compliant with IEC 62717 (Type A) and those that are not (Type B), with specific testing protocols for each.

Key updates in this edition include alignment of testing durations with IEC 62717, revision of sample sizes for statistical relevance, removal of certain temperature reduction requirements, and harmonization of life definitions with related standards.

INTRODUCTION
This standard is the conversion of IEC PAS 62722-2-1 into a full IEC performance standard
for LED luminaires for general lighting applications. It acknowledges the need for relevant
tests for luminaires using this new source of electrical light. The publication is seen in close
context with simultaneously developed and edited publication of performance standards for
luminaires in general and for LED modules. This standard does not consider luminaires
designed for LED lamps, which are covered in IEC 62722-1. Changes in the LED luminaires
standard will have impact on the LED module standards and vice versa, due to the behaviour
of LED. Therefore, in the development of the present standard, mutual consultancy of experts
of both products has taken place.
The provisions in the standard represent the technical knowledge of experts from the fields of
the semiconductor (LED chip) industry and of those of the traditional electrical light sources
and luminaires.
LUMINAIRE PERFORMANCE –
Part 2-1: Particular requirements for LED luminaires

1 Scope
This part of IEC 62722 specifies the performance requirements for LED luminaires, together
with the test methods and conditions, required to show compliance with this standard. It
applies to LED luminaires for general lighting purposes.
The following types of LED luminaires are distinguished.
– Type A – Luminaires using LED modules where compliance with IEC 62717 has been
proven.
– Type B – Luminaires using LED modules where compliance with IEC 62717 has not been
proven.
– Type C – Luminaires using a LED lamp and covered in IEC 62722-1.
The requirements of this standard only relate to type testing.
This standard does not cover Type C luminaires.
This standard does not cover LED luminaires that intentionally produce coloured light, neither
does it cover luminaires using OLEDs (organic LEDs).
These performance requirements are additional to the requirements in IEC 62722-1,
Clauses 1 to 9, except where in this Part 2-1 alternative methods of measurement or limits are
specified.
As this standard has been simultaneously developed and edited with the standard for LED
modules, where appropriate the compliance of the LED modules to the provisions of
IEC 62717 may be transferred to the whole luminaire.
Life time of LED luminaires is in most cases much longer than the practical test times.
Consequently, verification of manufacturer’s life time claims cannot be made in a sufficiently
confident way. For that reason the acceptance or rejection of a manufacturer’s life time claim,
past 25 % of rated life (with a maximum of 6 000 h), is out of the scope of this standard.
Instead of life time validation, this standard has opted for lumen maintenance categories at a
defined finite test time. Therefore, the category number does not imply a prediction of
achievable life time. The categories are lumen-depreciation character categories showing
behaviour in agreement with manufacturer’s information which is provided before the test is
started.
In order to validate a life time claim, an extrapolation of test data is needed. A general method
of projecting measurement data beyond limited test time is under consideration.
For explanation of recommended life time metrics see IEC 62717, Annex C.

To be published.

It may be expected that LED luminaires which comply with this standard will start and operate
satisfactorily at voltages between 92 % and 106 % of rated supply voltage and at an ambient
air temperature within the declared range of the manufacturer.
Evaluation of LOR (light output ratio) for LED luminaire is under consideration.

6.1 General test conditions
Test conditions for testing electrical and photometric characteristics, lumen maintenance and
life are given in Annex A.
All tests are measured on “n” LED luminaires of the same type. The number “n” shall be a
minimum of products as given in Table 3. LED luminaires used in the endurance tests shall
not be used in other tests.
Each sample luminaire shall comply with all the relevant tests except for the tests of 10.3
where one sample is required for each of the three separate tests mentioned in Table 2 and
Table 3. In order to reduce the time of testing, the manufacturer or responsible vendor may
submit additional luminaires or parts of luminaires provided that these are of the same
materials and design as the original luminaire and that the results of the test are the same as
if carried out on an identical luminaire.
LED luminaires with dimming control shall be adjusted to maximum output for all tests.
LED luminaires with adjustable CCT shall be adjusted/set to one fixed value as indicated by
the manufacturer or responsible vendor.
LED luminaires of linear geometry and variable length shall be tested at a length at which the

6.2 Luminaires using LED modules where compliance with IEC 62717 has been
proven (Type A)
Only the tests for measurement of initial performance are to be conducted, when the LED
module is operated within its temperature limit t .
p
The information for luminaire design given in IEC 62717, Clause B.1, requires LED modules
to be operated within their t temperature limit. The t temperature shall be measured
p p
according to the thermal test procedure defined in 12.4 of IEC 60598-1, (normal operation).
When the luminaire is operating at its own maximum rated ambient temperature for
performance (t ), the t limit (for the declared performance – Table 2, IEC 62717) of LED
q p
modules operating inside the luminaire shall not be exceeded. The test voltage for the
luminaire shall be 1,00 times the rated voltage of the luminaire. In luminaires intended to be
supplied with constant current, the test current shall be 1,00 times the rated current of the
luminaire.
For luminaires for road and street lighting and floodlights intended for outdoor use only, the
reduction of the measured temperature according to 3.12.1 of IEC 60598-2-3, and 5.12.1 of
IEC 60598-2-5, respectively shall not be applied for the t temperature of the LED module.
p
The ambient performance temperature t is measured in a draught-proof enclosure, as the air
q
temperature, at a position near one of the perforated walls on a level with the centre of the
luminaire, see item e), Clause K.1 of IEC 60598-1.
6.3 Luminaires using LED modules where compliance with IEC 62717 has not been
proven (Type B)
6.3.1 General
The manufacturer shall conduct testing for 25 % of rated life up to a maximum of 6 000 h.

Where the LED manufacturers provide data according to IEC 62717, the tests on the luminaire may be
carried out according to the column for Type A luminaires.
b
Testing requirements for Type A LED luminaires will depend on the requirements of IEC 62717. It is not the
intention to re-measure the values of a product complying with its own standard. However where luminaires
combine different LED modules in one luminaire, or where secondary optics are added in the luminaire,
certain parameters may be required to be measured, e.g. if there is a mixing of colours, the final CRI and
CCT need to be measured in the luminaire.

Annex A
(normative)
Method of measuring LED luminaire characteristics

A.1 General
The provisions of Clause A.1 of IEC 62717 apply to the LED luminaire, except that the
wording in the third paragraph, first sentence “in the temperature interval (t rated − 5, t
p p
rated)” does not apply to the LED luminaire.
Where a rated ambient performance temperature t other than 25 °C is advised by the
q
manufacturer, a correction factor will need to be established to correct the measured luminous
flux value at 25 °C to the luminous flux value at the declared ambient temperature. This shall
be done using relative photometry in a temperature controlled cabinet.
In addition for LED luminaires the international and regional requirements shall be followed
for measurement methods and provision of data but format may be optional.
A.2 Electrical characteristics
The provisions of Clause A.2 of IEC 62717 apply to the LED luminaire.
A.3 Photometric characteristics
The provisions of Clause A.3 of IEC 62717 apply to the LED luminaire.

Annex B
(informative)
Explanation of recommended life time metrics

B.1 General
Life time of LED luminaire can be far more than what practically can be verified with testing.
Furthermore the decrease in light output differs per manufacturer making general prediction
methods difficult. This standard has opted for lumen maintenance categories that cover the
initial decrease in luminous flux until an operational time as stated in 6.1. Due to this limited
test time, the claimed life of a LED luminaire cannot be confirmed nor rejected in most cases.
NOTE The useful life of a luminaire refers to the lumen maintenance projections of the LED light sources
integrated into that luminaire or the number of hours that a LED luminaire will deliver a sufficient amount of light in
a given application.
Luminaire life, on the other hand, has to do with the reliability of the components of a LED luminaire as a system,
including the electronics, materials, housing, wiring, connectors, seals, and so on. The entire system lasts only as
long as the critical component with the shortest life, whether that critical component is a weather seal, an optical
element, a LED, or something else. From this point of view, LED light sources are simply one critical component
among many – although they are often the most reliable component in the whole lighting system.
If a LED luminaire is equipped with a replaceable LED module, luminaire life can be decoupled from the LED
module and its life. This brings luminaire life closer to the current definition of luminaire life for conventional light
sources.
B.2 Life time specification
It is recommended for LED luminaires to specify the lumen maintenance apart from the abrupt
failures in a standardised way giving more insight in light output behaviour. One can
distinguish 2 types of failures.
Lifetime specification for gradual light output degradation
The gradual light output degradation of a population of LED luminaires at a certain point in
time is called useful life and expressed in general as L B .
x y
The “B life” expresses the age at which a given percentile of LED luminaires cannot meet the
lumen maintenance factor x. Light output lower than the lumen maintenance factor x is called
a parametric failure because the product produces less light but still operates. “B ” life is the
age at which 10 % of products have failed parametrically. The age at which 50 % of the items
parametrically fail, the “B life”, is called median useful life. The population includes
operating LED luminaires only; non-operative products are excluded.
Lifetime specification for abrupt light output degradation
The abrupt light output degradation of a population of LED luminaires at a certain point in time
is called time to abrupt failure and expressed as C .
y
The recommended life time metrics for specifying LED module life is explained in Annex C of
IEC 62717 and apply to the LED luminaire. For compliance criteria see 10.2 of this standard.
