Full title and description

St IEC 62031-2018 — LED modules for general lighting — Safety specifications. Specifies general and safety requirements for LED modules used in general lighting applications, covering non-integrated, semi-integrated and integrated LED modules and including marking, electrical, thermal and photobiological safety requirements and related tests.

Abstract

This standard (IEC 62031:2018, 2nd edition) defines safety requirements and test methods for LED modules intended for general lighting. It replaces the first edition (2008) and its amendments, and introduces clarified scope and definitions (including replaceable/non-replaceable classifications), updated marking and working-voltage requirements, revised provisions for terminals and thermal management, guidance for luminaire design, and new abnormal-temperature and photobiological safety considerations. It is a safety specification only (performance requirements are covered by IEC 62717).

Scope

IEC 62031:2018 specifies general and safety requirements for LED modules for general lighting. It covers non-integrated LED modules (LEDni) and semi‑integrated LED modules (LEDsi) for operation under constant voltage, constant current or constant power, and integrated LED modules (LEDi) for use on DC supplies up to 250 V or AC supplies up to 1 000 V (50/60 Hz). The standard applies to integral, built‑in or independent LED modules but does not apply to LED lamps, LED packages or automotive LED modules. It focuses on safety — electrical, thermal, mechanical and photobiological — and on marking and information needed for safe installation and use.

Key topics and requirements

• Definitions and classification: replaceable, non‑replaceable and non‑user‑replaceable LED modules; distinctions between LEDi, LEDni and LEDsi.
• Marking and documentation: structured marking clause, required markings for built‑in and independent modules, working voltage designation and traceability information.
• Electrical safety tests: insulation, dielectric strength, protective earthing and terminal requirements for various supply types and voltages.
• Thermal management: temperature limits, heat‑transfer provisions, tests for abnormal temperature conditions and requirements for safe dissipation of heat.
• Mechanical and ingress protection considerations relevant to module mounting and luminaire integration.
• Photobiological safety: provisions and tests to evaluate optical hazards (blue‑light, UV/IR) for users and installers.
• Luminaire design guidance: information for designers regarding working voltage, water contact and safe integration of modules into luminaires.
• Exclusions and interfaces: clarifies that performance requirements are outside scope (see IEC 62717) and notes interfaces with control gear and luminaire standards.

Typical use and users

Used by LED module manufacturers, luminaire designers and integrators, conformity assessment and test laboratories, certification bodies, regulatory agencies and technical compliance teams. It is referenced by product developers for safety design checks, by testing labs when performing safety tests, and by procurement and regulatory staff to specify safety compliance for LED modules intended for general lighting.

Related standards

Commonly used together with or referenced to: IEC 62717 (LED modules — performance requirements), IEC 62471 (photobiological safety of lamps and lamp systems), IEC 62504 (LED terms and definitions), IEC 61347‑1 / IEC 61347‑2‑13 (control gear requirements), IEC 62384 (electrical characteristics of control gear), IEC 60598 (luminaires — general requirements) and applicable EN adoptions (EN IEC 62031, consolidated versions and national adoptions).

FAQ

Q: What is this standard?

A: IEC 62031:2018 is the international safety specification for LED modules for general lighting (second edition, published 8 March 2018).

Q: What does it cover?

A: It covers general and safety requirements (electrical, thermal, mechanical, marking and photobiological) and associated tests for non‑integrated, semi‑integrated and integrated LED modules used in general lighting. It does not cover LED lamps, LED packages or automotive LED modules, and does not set performance (photometric) requirements.

Q: Who typically uses it?

A: LED module manufacturers, luminaire designers, test laboratories, certification bodies, regulatory/compliance teams and procurement/specification engineers.

Q: Is it current or superseded?

A: The 2018 edition has been superseded — IEC lists a more recent edition (IEC 62031:2026). The 2018 edition was recorded with a withdrawal date of 23 February 2026; users should consult the latest edition (2026) for current mandatory safety requirements and any new tests or limits introduced since 2018.

Q: Is it part of a series?

A: Yes. IEC 62031 is the safety part of a set of LED module standards. Performance requirements are covered by IEC 62717; there are related documents for test methods, definitions and photobiological safety (for example IEC 62504, IEC 62471) and complementary standards for control gear and luminaires (IEC 61347 series, IEC 62384, IEC 60598).

Q: What are the key keywords?

A: LED module, safety, marking, working voltage, thermal management, abnormal temperature test, photobiological safety, LEDi, LEDni, LEDsi, IEC 62031.
