LED modules - Safety requirements
Scope: IEC 62031:2026 specifies safety requirements for LED modules for operation on DC supplies up to 1 500 V or on AC supplies up to 1 000 V. This document does not include requirements for performance characteristics of LED modules.
This document does not apply to:
- LED packages;
- LED modules for automotive lighting;
- OLED modules;
- LED lamps.
This third edition cancels and replaces the second edition published in 2018. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Complete review of the document structure, detailed technical requirements and tests, including but not limited to what is individually described under items b) to i);
b) Clarification of the scope and revision of the applicability of this document to independent and integral LED modules;
c) Updated terms and definitions;
d) Clearer specification for clause general requirements and clause general test requirements;
e) Update of the marking clause, such as marking of control terminals;
f) A full review and update of the electrical safety, thermal safety, and mechanical safety requirements preventing misinterpretation and ambiguity;
g) Updated photobiological safety requirements;
h) Revised and updated fault conditions and abnormal conditions requirements;
i) Removal of the annex relating to conformity testing during manufacture.

IEC 62031:2018
LED modules for general lighting - Safety specifications
Scope: IEC 62031:2018 specifies general and safety requirements for light-emitting diode (LED) modules:
- non-integrated LED modules (LEDni modules) and semi-integrated LED modules (LEDsi modules) for operation under constant voltage, constant current or constant power;
- Integrated LED modules (LEDi modules) for use on DC supplies up to 250 V or AC supplies up to 1 000 V at 50 Hz or 60 Hz.
This second edition cancels and replaces the first edition published in 2008, Amendment 1:2012 and Amendment 2:2014. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a. the scope was clarified as well as the wording in several other clauses;
b. the normative references were updated;
c. the definitions for "replaceable LED module", "non-replaceable LED module" and "non-user replaceable LED module" were introduced while other definitions covered by IEC 62504 have been removed;
d. the marking clause was restructured and a table added to provide an informative overview;
e. the marking requirements for built-in LED modules were changed;
f. the entry for the marking with the working voltage was revised;
g. the provisions for terminals and heat management were revised;
h. Annex B was deleted;
i. information for luminaire design with regard to working voltage and water contact was introduced;
j. an abnormal temperature test was introduced.

IEC TR 63139:2018
Explanation of the mathematical addition of working voltages, insulation between circuits and use of PELV in TC 34 standards
Scope: IEC TR 63139:2018(E) is related to the insulation coordination in TC 34 standards and provides explanations on mathematical addition of working voltages, insulation between circuits, use of protective extra low voltage (PELV) and insulation between LV supply and control line conductors in order to cover new technologies associated with the use of LED light sources and controllable products.
It describes in which way the addition of supply voltages and working voltages can be arranged for an assessment of the electrical insulation requirements (e.g. creepage distances and clearances) in a system if a first failure occurs.
