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.
This International Standard specifies general and safety requirements for light-emitting diode (LED) modules: - LED modules without integral control gear for operation under constant voltage, constant current or constant power; - self-ballasted LED modules for use on d.c. supplies up to 250 V or a.c. supplies up to 1 000 V at 50 Hz or 60 Hz.
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.
