(Main)Self-ballasted LED lamps for general lighting services with supply voltages > 50 V - Performance requirements
Self-ballasted LED lamps for general lighting services with supply voltages > 50 V - Performance requirements
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.
LED-Lampen mit eingebautem Vorschaltgerät für Allgemeinbeleuchtung mit Versorgungsspannungen > 50 V - Anforderungen an die Arbeitsweise
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. c) Les exigences de marquage s'appliquent au boîtier et non au produit. d) Le nombre de lampes à soumettre aux essais est spécifique aux essais. e) Les premières exigences sont données pour régler la couleur des lampes à couleur ajustable et le niveau de flux lumineux des lampes à variation d'intensité. f) La structure des essais est divisée entre exigences et conformité. g) La conformité statistique est divisée en individuelle et moyenne. h) Les exigences sur la lumière de sortie sont étendues à la distribution d'intensité lumineuse, l'intensité de crête, l'angle de faisceau et l'efficacité. i) L'utilisation des termes 'température de couleur proximale' et 'coordonnées trichromatiques' est corrigée. j) Le nombre de catégories de tolérance est réduit de 8 à 4 et divisé entre les valeurs initiales et valeurs de maintien. k) Le rendu des couleurs est évalué différemment à l'état initial et à l'état de maintien. l) Trois catégories de maintien de flux lumineux sont données au lieu de cinq. m) Les essais d'endurance sont entièrement rétablis. n) L'article sur la vérification (auparavant appelée évaluation) est complété. o) Des informations pour la conception de luminaires sont ajoutées. p) La stabilisation est plus précise (Annexe A sur la méthode de mesure des caractéristiques des lampes) et des paramètres photométriques et colorimétriques supplémentaires ont été ajoutés. q) L'Annexe B sur la mesure du flux lumineux est incluse dans l'Annexe A. Une nouvelle Annexe B fournit le code photométrique. r) D'autres annexes ont été ajoutées. L'Annexe C et l'Annexe D sur le facteur de déplacement, l'Annexe E sur les valeurs et la fiabilité de la durée de vie et l'Annexe F qui donne des exemples de puces de LED et de boîtier de LED.
LED-sijalke za splošno razsvetljavo z vgrajeno predstikalno napravo pri napajalni napetosti nad 50 V - Tehnične zahteve (IEC 62612:2013)
Ta mednarodni standard določa zahteve glede zmogljivosti, vključno s preskusnimi metodami in pogoji, ki so potrebni za preverjanje skladnosti sijalk LED z vključenimi sredstvi za stabilno delovanje, ki so namenjene za domačo in podobno splošno razsvetljavo ter imajo:
• nazivno moč do 60 W;
• nazivno napetost od 50 do 250 VAC;
• svetilno osnovo, kot je opredeljeno v standardu IEC 62560.
Te zahteve glede zmogljivosti so dodane k zahtevam iz standarda IEC 62560., Edina lastnost, podana s tem standardom, ko se ta uporablja za namene zamenjave, je informacija o največjem obsegu svetilke. Zahteve iz tega standarda se nanašajo na tipsko preskušanje. Ta standard zajema svetilke LED, ki namenoma proizvajajo belo svetlobo, osnovano na neorganskih svetilkah LED.
Priporočila za preskušanje celotnega proizvoda ali serije so v obravnavi. Življenjska doba svetilk LED je v večini primerov precej daljša od preskusnih časov v praksi. Posledično ni mogoče preveriti proizvajalčeve trditve o življenjski dobi z zadostno mero zanesljivosti, ker projekcija preskusnih podatkov v prihodnost ni standardizirana. Zaradi tega sprejetje ali zavrnitev proizvajalčevih trditev o življenjski dobi nad nazivno življenjsko dobo, kot je opredeljeno v točki v 7.1, je zunaj področja uporabe tega standarda. Namesto preverjanja veljavnosti življenjske dobe ta standard določa kode vzdrževanja lumnov pri opredeljenem končnem preskusnem času. Zato številka kode ne predvideva napovedi dosegljive življenjske dobe. Kategorije, ki jih predstavljajo kode, so kategorije znižanja vrednosti lumnov, ki delujejo v skladu z informacijami proizvajalca, ki so na voljo pred začetkom preskusa. Za preverjanje trditve o življenjski dobi obstaja več metod za ekstrapolacijo preskusnih podatkov. Presoja se splošna metoda projiciranja podatkov meritev zunaj omejenega preskusnega časa. Merilo za uspel/neuspel preskus življenjske dobe, kot je določeno v tem standardu, se razlikuje od nazivnih meritev proizvajalcev. Za razlago priporočenih meritev življenjske dobe glej dodatek E. OPOMBA: Če žarnice delujejo v svetilki, se lahko podatki o zmogljivosti razlikujejo od vrednosti v tem standardu, predvsem zaradi komponent svetilke, ki vplivajo na delovanje žarnice.

PERFORMANCE REQUIREMENTS
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.
---------------------- Page: 10 ----------------------

62612 IEC:2013 – 5 –
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 text of this standard is based on the following documents:

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.

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.
