LUMINAIRE PERFORMANCE –
Part 2-1: Particular requirements for LED luminaires
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 62722-2-1 has been prepared by subcommittee 34D: Luminaires,

of IEC technical committee 34: Lamps and related equipment.

This first edition of IEC 62722-2-1 cancels and replaces IEC PAS 62722-2-1. published in

2011. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the Publicly

Available Specification.

a) The testing time is aligned with IEC 62717 and the option of 2 000 h is removed. Products

containing modules not in compliance with IEC 62717 are now tested to 6 000 h.
b) Testing sample sizes have been modified to give valid statistical data.

c) The temperature reduction of 10 °C for street lanterns and floodlights has been removed.

d) Life definitions have been updated and aligned with IEC 62717.

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.
___________

– 8 – IEC 62722-2-1:2014 © IEC 2014

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.

5 Not used
6 Test conditions
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

parameters are given (e.g. performance per x cm).
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 .

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.

The ambient performance temperature t is measured in a draught-proof enclosure, as the air

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.
