IEC 62031:2026

Overview

IEC 62031:2026 – LED Modules: Safety Requirements is an international standard developed by the International Electrotechnical Commission (IEC). It specifies comprehensive safety requirements for LED modules intended for operation on DC supplies up to 1,500 V and AC supplies up to 1,000 V. This standard is crucial for manufacturers, testing laboratories, and product designers working with LED technology to ensure product safety and regulatory compliance in a fast-growing market segment.

This third edition replaces the 2018 version with technical revisions for enhanced clarity, expanded safety requirements, and updates reflecting advancements in LED module technology. Importantly, the standard does not address performance characteristics or apply to LED packages, automotive LED modules, OLED modules, or complete LED lamps.

Key Topics

• Scope & Applicability

  • Applies to built-in LED modules for general lighting operating under specified voltage conditions.
  • Excludes LED packages, automotive LED modules, OLED modules, and finished LED lamps.

• Module Classification

  • Integrated (LED module with built-in controlgear)
  • Semi-integrated (some controlgear built in, separate power supply required)
  • Non-integrated (external controlgear needed)

• Safety Areas Covered

  • Electrical Safety: Protection against electric shock, safe electrical design, insulation, and earthing requirements.
  • Thermal Safety: Resistance to heat and flammability, and heat management to prevent hazardous temperatures in regular and fault conditions.
  • Mechanical Safety: Constructional stability, mechanical strength, and durability of electrical connections.
  • Photobiological Safety: Evaluation of ultraviolet (UV), blue light, and infrared radiation hazards to skin and eyes.

• Testing and Compliance

  • Specifies type testing to validate design compliance with safety requirements.
  • Requirements for marking (including content, legibility, and durability), particularly regarding control terminals.
  • Guidance for handling fault and abnormal conditions to prevent safety risks.

• Definitions and Terminology

  • Updated and clarified key terms for consistency and global understanding.

Applications

IEC 62031:2026 offers practical benefits in a wide range of industries and applications:

• Lighting Manufacturers: Ensures new and existing LED modules meet essential safety requirements, facilitating market access and product reliability.
• Product Designers/Engineers: Guides safer designs for luminaires, helping to integrate LED modules without compromising user or installer safety.
• Testing Laboratories: Provides a standardized framework for safety assessments and type-testing of LED modules.
• Compliance Officers: Supports regulatory conformity for products sold internationally by aligning with recognized best safety practices.
• Installers and Specifiers: Ensures that installed LED lighting systems are safe for end-users and compatible with other system components.

Adherence to this standard helps mitigate risks related to electric shock, fire, mechanical failure, and photobiological hazards, supporting safer lighting environments in commercial, residential, and industrial settings.
