Self-ballasted LED lamps for general lighting services with supply voltages > 50 V - Performance requirements

IEC 62612:2013 specifies the performance requirements, together with the test methods and conditions, required to show compliance of LED lamps with integral means for stable operation, intended for domestic and similar general lighting purposes, having:
- a rated power up to 60 W;
- a rated voltage of > 50 V a.c. up to 250 V a.c.;
- a lamp cap as listed in IEC 62560. This first edition of IEC 62612 cancels and replaces IEC/PAS 62612. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC/PAS 62612.
a) The standard explicitly states that real life time tests are not part of the test regime. Instead, a period of up to 6 000 h is chosen in order to assess manufacturers' claims of maintenance.
b) Technical features have been adapted to IEC/PAS 62717 (performance of LED modules) as far as possible. Examples are the family approach and the temperature measuring point.
c) Marking requirements are shifted from the product to the packaging.
d) The number of lamps to be tested is made test specific, not general.
e) First requirements are given for setting the colour for colour adjustable lamps and the luminous flux level of dimmable lamps.
f) The structure of tests is clearly divided between requirement and compliance.
g) Statistical compliance is separated into individual and average.
h) Light output requirements are extended to luminous intensity distribution, peak intensity, beam angle and efficacy.
i) The use of the terms "correlated colour temperature" and "chromaticity coordinates" is corrected.
j) The number of tolerance categories is reduced from 8 to 4, and split between initial and maintained values.
k) Colour rendering is differently assessed at initial and maintained state.
l) Three lumen maintenance categories are given instead of five.
m) The endurance tests are completely re-established.
n) The verification (formerly: assessment) clause is completed.
o) Information for luminaire design is added.
p) Stabilisation is more precise (Annex A on the method of measuring lamp characteristics) and extension is made for the additional photometric and colorimetric parameters.
q) Annex B on measuring luminous flux is contained in Annex A. New Annex B provides the photometric code.
r) Further annexes are added: Annex C and D for displacement factor, Annex E for life time metrics/reliability and Annex F for examples of LED dies and LED packages. The contents of the corrigendum of October 2016 have been included in this copy.

Lampes à LED autoballastées pour l'éclairage général avec des tensions d'alimentation > 50 V - Exigences de performances

La CEI 62612:2013 spécifie les exigences de performances, ainsi que les conditions et les méthodes d'essais, requises pour assurer la conformité des lampes à LED à dispositif de stabilisation incorporé, destinées à l'éclairage domestique et à l'éclairage général similaire, ayant:
- une puissance assignée pouvant atteindre 60 W;
- une tension assignée comprise entre 50 V c.a. et 250 V c.a.;
- un culot de lampe tel qu'indiqué dans la CEI 62560. Cette première édition de la CEI 62612 annule et remplace la CEI/PAS 62612. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à la CEI/PAS 62612.
a) La norme indique explicitement que les essais de durée de vie réelle ne font pas partie du régime d'essais. Au lieu de cela, on choisit une période pouvant atteindre 6 000 h pour évaluer les déclarations de maintien données par un fabricant.
b) Des caractéristiques techniques ont été adaptées autant que possible à la CEI/PAS 62717 (performances des modules de LED). Des exemples incluent l'utilisation de familles et le point de mesure de la température.

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 62612 has been prepared by subcommittee 34A: Lamps, of IEC

technical committee 34: Lamps and related equipment.

This first edition of IEC 62612 cancels and replaces IEC/PAS 62612. This edition constitutes

a technical revision.

This edition includes the following significant technical changes with respect to

IEC/PAS 62612.

a) The standard explicitly states that real life time tests are not part of the test regime.

Instead, a period of up to 6 000 h is chosen in order to assess manufacturers’ claims of

maintenance.

b) Technical features have been adapted to IEC/PAS 62717 (performance of LED modules)

as far as possible. Examples are the family approach and the temperature measuring

point.
c) Marking requirements are shifted from the product to the packaging.
d) The number of lamps to be tested is made test specific, not general.

e) First requirements are given for setting the colour for colour adjustable lamps and the

luminous flux level of dimmable lamps.
f) The structure of tests is clearly divided between requirement and compliance.
g) Statistical compliance is separated into individual and average.

h) Light output requirements are extended to luminous intensity distribution, peak intensity,

beam angle and efficacy.

i) The use of the terms “correlated colour temperature” and “chromaticity coordinates” is

corrected.

INTRODUCTION

This International Standard is the first edition of a performance standard (precursor:

IEC/PAS 62612) for self-ballasted LED lamps for general lighting applications and

acknowledges the need for relevant tests for this new source of electrical light, sometimes

called “solid state lighting”.

The provisions in this 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.

---------------------- Page: 8 ----------------------
62612  IEC:2013 – 7 –
SELF-BALLASTED LED LAMPS FOR GENERAL
LIGHTING SERVICES WITH SUPPLY VOLTAGES > 50 V –
PERFORMANCE REQUIREMENTS
1 Scope

This International Standard specifies the performance requirements, together with the test

methods and conditions, required to show compliance of LED lamps with integral means for

stable operation, intended for domestic and similar general lighting purposes, having:

• a rated power up to 60 W;
• a rated voltage of > 50 V a.c. up to 250 V a.c.;
• a lamp cap as listed in IEC 62560.

These performance requirements are additional to the safety requirements in IEC 62560.

The only feature provided by this standard, when applied for replacement purposes, is

information on maximum lamp outlines.

The requirements of this standard relate to type testing. This standard covers LED lamps that

intentionally produce white light, based on inorganic LEDs.

Recommendations for whole product testing or batch testing are under consideration.

The life time of LED lamps 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, because projecting test data further in time is not standardised. For that

reason the acceptance or rejection of a manufacturer's life time claim, past an operational

time as stated in 7.1, is out of the scope of this standard.

Instead of life time validation, this standard has opted for lumen maintenance codes at a

defined finite test time. Therefore, the code number does not imply a prediction of achievable

life time. The categories, represented by the code, are lumen-depreciation character

categories showing behaviour in agreement with manufacturer’s information, provided before

the test is started.

In order to validate a life time claim, several methods of test data extrapolation exist. A

general method of projecting measurement data beyond limited test time is under
consideration.

The pass/fail criterion of the life time test as defined in this standard is different from the life

time metrics claimed by manufacturers. For explanation of recommended life time metrics,

see Annex E.

NOTE When lamps are operated in a luminaire the claimed performance data can deviate from the values

established via this standard due to e.g. luminaire components that impact the performance of the lamp.

For the purposes of this document, the terms and definitions given in IEC/TS 62504 and

IEC 60050-845 as well as the following apply.
3.1
rated value

quantity value for a characteristic of an LED lamp for specified operating conditions

Note 1 to entry: The value and the conditions are specified in this standard, or assigned by the manufacturer or

responsible vendor.
3.2
test voltage
voltage at which tests are carried out
Note 1 to entry: Specification of test voltage is made in A.2.
---------------------- Page: 10 ----------------------
62612  IEC:2013 – 9 –
3.3
lumen maintenance (of an LED lamp)
luminous flux maintenance

ratio of the luminous flux emitted by an LED lamp at a given time in its life to its initial

luminous flux, the lamp being operated under specified conditions
Note 1 to entry: This ratio x is generally expressed in per cent.

Note 2 to entry: The lumen maintenance of an LED lamp is the effect of decrease of the lumen output of the LED(s)

or a combination of this with failure(s) of LED(s) if the lamp contains more than one LED.

[SOURCE: IEC 60050-845:1987, 845.07.65, modified — the term "LED" and the note 2 to

entry are added]
3.4
initial value

photometric, colorimetric and electrical characteristics at the end of the ageing period and

stabilisation time
3.5
maintained value

photometric, colorimetric and electrical characteristics at an operational time, including

stabilisation time
Note 1 to entry: The operational time is stated in 7.1.
3.6
life (of an individual LED lamp)

length of time during which an LED lamp provides at least claimed percentage of the initial

luminous flux, under standard conditions

Note 1 to entry: An LED lamp has thus reached its end of life, when it no longer provides claimed percentage of the

initial luminous flux. Life is always published in combination of life (L ) at lumen maintenance (x) and the failure

fraction (F ) (see 3.8)

Note 2 to entry: Any built-in electronic controlgear, however, may show a sudden end of life failure. The definition

3.6 implies that an LED lamp giving no light at all, due to an electronic failure, has actually reached end of life,

since it no longer complies with the minimum luminous flux level as declared by the manufacturer or responsible

vendor.
3.7
rated lamp life

length of time during which a population of LED lamps provides at least the claim for luminous

flux percentage x and less or equal the claim for failure fraction percentage y, as declared by

the manufacturer or responsible vendor
Note 1 to entry: For sample size see Clause 7.
Note 2 to entry: Notes to entry 1 and 2 of 3.6 apply.
Note 3 to entry: Rated lamp life is expressed in hours.
3.8
failure fraction at rated life

percentage y of a number of LED lamps of the same type, that at their rated life designates

the percentage (fraction) of failures

Note 1 to entry: This failure fraction expresses the combined effect of all components of an LED lamp including

mechanical components, as far as the light output is concerned. The effect of the LED could either be less light

than claimed or no light at all.
