Overview
IEC 62868-2-3:2021 outlines the safety requirements for flexible organic light emitting diode (OLED) tiles and panels specifically designed for general indoor lighting applications. The standard, developed by the International Electrotechnical Commission (IEC), applies to OLED tiles and panels intended for use with power supplies up to 120 V ripple-free DC and which are designed to be bent during the manufacturing process, such as in the production of curved luminaires.
Flexible OLED panels present unique mechanical and safety considerations compared to rigid OLED lighting elements. This standard provides manufacturers, designers, and testing organizations with clear requirements to ensure electrical and mechanical safety during manufacturing, installation, and use.
Key Topics
- Scope and Applicability: Safety requirements for flexible OLED panels and tiles used in general indoor lighting, with power supplies up to 120 V DC.
- Product Classification:
- Glass-based flexible OLED panels: Use thin glass as substrate and/or encapsulation material.
- Film-based flexible OLED panels: Utilize barrier film or metal foil components.
- Mechanical Strength and Testing:
- Vibration, impact, bending radius, and cycle testing based on panel construction and classification.
- Specialized tests for both glass and film substrates ensure mechanical robustness, especially after repeated bending.
- Marking and Labeling:
- Manufacturers must indicate OLED classification, minimum bending radius, and maximum bending cycles on product packaging or datasheets to support safe use and installation.
- Fault Conditions:
- Panels must not compromise safety (no broken glass, smoke, fire, or loose parts) under electrical or mechanical fault conditions, including overpower, input instability, or excess bending.
- Electrical Safety:
- Insulation resistance and electric strength tests are aligned with general OLED light source requirements.
- Resistance to Environmental Factors: Includes requirements for resilience against dust, moisture, thermal stress, and fire.
- Photobiological Safety:
- Panels are not expected to pose UV, infrared, or blue light hazards in general lighting applications.
Applications
Flexible OLED tiles and panels certified to IEC 62868-2-3:2021 are primarily used in:
- Curved Luminaires: OLED panels that can be safely bent during manufacturing to fit into non-standard, curved, or artful lighting designs.
- Architectural Lighting: Innovative fixture designs requiring slim, lightweight, and flexible light sources for integration into walls, ceilings, or furniture.
- Custom and Commercial Lighting Installations: Environments such as retail stores, hospitality venues, museums, and exhibitions where customized form factors and advanced lighting aesthetics are desired.
- OEM Lighting Modules: Manufacturers and luminaire designers sourcing flexible OLED modules for integration into their proprietary lighting products.
By ensuring compliance with IEC 62868-2-3:2021, product developers can deliver advanced lighting systems that meet international safety standards and improve reliability in demanding or unique installation scenarios.
