Lighting

IEC TS 62972:2016 establishes terms and definitions specific for general lighting OLED light sources and related equipment.

IEC TR 63036:2016(E) specifies the electrical interface and test procedures for the control by mains voltage phase-cut dimming of the brightness of mains operated electronic lighting equipment intended to be controlled by mains voltage phase-cut dimmers, such as LED integrated lamps, and light sources with external control gear. Electronic switches that use a comparable circuitry to a phase-cut dimmer but do not contain means for the adjustability of the phase-cut angle should fulfill the same requirements as a phase-cut dimmer. Safety requirements are not covered by this document, but by respective product standards.

IEC 62922:2016 specifies the performance requirements of OLED tiles and panels for use on DC supplies up to 120 V or AC supplies up to 50 V at 50 Hz or 60 Hz for indoor and similar general lighting purposes.

IEC 62776:2014 specifies the safety and interchangeability requirements, and the exchange operation together with the test methods and conditions required to show compliance of double-capped LED lamps with G5 and G13 caps, intended for replacing fluorescent lamps with the same caps, having:
- a rated power up to 125 W;
- a rated voltage up to 250 V.
The contents of the corrigendum of March 2015 and interpretation sheet 1 of June 2018 have been included in this copy.

IEC 62722-2-1:2014 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. 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.

IEC 62722-1:2014 covers specific performance and environmental requirements for luminaires, incorporating electric light sources for operation from supply voltages up to 1 000 V. Unless otherwise detailed, performance data covered under the scope of this standard are for the luminaires in a condition representative of new manufacture, with any specified initial aging procedures completed. This first edition cancels and replaces IEC PAS 62722-1 published in 2011 and constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC PAS 62722-1.
a) The inclusion of more precise requirements for the comparison of the photometric distribution shape, with the comparison method given in Annex D.
b) Further regional standards added to the schedule given in Annex A.

IEC 62717:2014+A1:2015+A2:2019 specifies the performance requirements for LED modules, together with the test methods and conditions, required to show compliance with this standard. This first edition cancels and replaces IEC PAS 62717 published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC PAS 62717:
- all terms and definitions are aligned with IEC 62504 and relevant documents of CIE. For example, general terms like "rated value" are shifted to IEC 62504.
- a statement on the applicability on a population is included.
- the normative references are completed and cleaned from standards that are not in use.
- with regard to EMC, references to harmonic currents are given.
- the change, which has an effect on most parts of the standard, is the split of failure mechanisms into abrupt failures and luminous flux depreciation. Consequently, new terms and definitions, new requirements for lumen maintenance and a complete new structure and contents of Annex C are introduced.
- transition from tpmax to tprated is made, with the background that there is not one tpmax, but a choice of tp(rated) values, in combination with lifetime.
- places where to mark (product, packaging, data sheets) are changed, and as a consequence of the split of failure mechanisms, new parameters are listed. Further, changes in the endurance test (ramping speed of temperature) are reflected in marking.
- the concept of displacement factor instead of power factor is introduced. This led to new definitions, requirements and Annexes E and F.
- the requirements on luminous efficacy are changed.
- the requirements, associated with the family concept are reviewed.
- statistics, based on confidence intervals are removed. This concerns requirements and limits for LED module power and luminous flux and deletion of Annex E.
- new requirements for lumen maintenance are introduced.
- as part of the endurance test, the maximum light decrease after accelerated operation life test is now fixed.
- with regard to the discussion on type test and sample size, the number of pieces in a test sample is drastically reduced, see Table 7.
- Annex A on measuring methods is completely restructured and reviewed, for example for ambient temperature and for shortening of stabilisation time when conducting subsequent light output measurements.
- for electrical characteristics, the ageing time may be chosen as 500 h.
- for photometric data file formats, reference is given to IEC 62722-1.
- mistakes in the photometric code (Annex D) are corrected.
- Annex G on optimised test duration is removed; instead, an INF sheet shall be published.
- from the luminaire standard, a new Annex H on "Test equipment for temperature measurement" is taken over.
- finally, the Bibliography is updated.
This consolidated version consists of the first edition (2017), its amendment 1 (2015) and its amendment 2 (2019). Therefore, no need to order amendment in addition to this publication.

IEC 62639:2012 specifies the performance requirements for fluorescent induction lamps for general lighting purposes. In this standard, the term "lamp" stands for "induction lamp". It may be expected that lamps 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 between 10 °C and 50 °C, when operated with ballasts complying with IEC 60929 and IEC 61347-2-3, as far as applicable, and in a luminaire complying with IEC 60598-1.

IEC 62612:2013+A1:2015+A2:2018 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. This consolidated version consists of the first edition (2013), its amendment 1 (2015) and its amendment 2 (2018). Therefore, no need to order amendment in addition to this publication.
