Overview
IEC 63146:2019 is an international standard published by the International Electrotechnical Commission (IEC) that defines requirements for specification sheets of LED packages intended for general lighting applications. Specifically, the standard applies to LED packages emitting white light used for general illumination. Unlike performance or safety standards, IEC 63146:2019 does not include compliance criteria but focuses on consistent, clear, and comprehensive presentation of technical data in specification sheets.
This standard is essential for manufacturers, designers, and users of LED lighting products, enabling effective communication of LED package characteristics, ensuring interoperability, and facilitating product comparison and selection.
Key Topics
The standard outlines structured product information and data presentation formats, harmonizing them with referenced ANSI C78.374-2015 standards while incorporating specific deviations applicable to general lighting LEDs. Key elements specified include:
-
General Product Information
- Mandatory titles and graphic presentation aligned with ANSI's guidelines.
-
Performance Characteristics
- Correlated Colour Temperature (CCT) versus luminous flux relationship.
- Colour binning details, with chromaticity values for given CCTs presented clearly.
- Spectral Power Distribution and Luminous Intensity Distribution.
- Luminous flux dependencies on forward current and temperature.
- Colour-over-angle data referencing with access details (e.g., URLs).
- Luminous flux and forward voltage binning in tabular formats.
- Graphical representation of colour coordinate variation versus temperature.
- Graphs of luminous efficacy versus forward current with influencing factors noted.
-
Operational Characteristics
- Defined operating limits such as maximum forward pulse current, pulse width, duty cycle, reverse voltage, and minimum forward current.
- Thermal resistance specifications detailed from junction to case or soldering point, based on either dissipated or input power.
- Electrostatic discharge (ESD) human body model withstand voltage or classification.
- Electrical parameters including forward current vs forward voltage and temperature characteristics.
-
Physical and Electrical Connection Characteristics
- Mechanical dimensions and diagrams of electrical connections for clarity in design and assembly integration.
-
Product Handling
- Guidelines for assembly processes and packing information for LED packages.
- Moisture sensitivity level classification recommendations, suggesting IPC/JEDEC J-STD-020E or equivalent standards for reflow and moisture management.
-
Measurement Method Reporting
- Photometric, chromaticity, and thermal data measurement procedures to ensure data reliability and reproducibility.
Applications
IEC 63146:2019 applies directly to manufacturers, suppliers, and integrators in the LED lighting industry who develop or utilize white light LED packages for general lighting. Typical use cases include:
- LED Package Manufacturers seeking to standardize specification sheets for global markets.
- Lighting Product Designers and Engineers who require detailed and standardized LED package information for system design and performance analysis.
- Quality Assurance Teams ensuring accuracy and transparency in LED technical data.
- Procurement and Specification Writers needing reliable and comparable LED product sheets for purchasing decisions.
- Standardization Bodies and certification organizations referencing data consistency and reporting.
By providing uniform templates and content requirements, IEC 63146 aids in minimizing errors, improving product interoperability, and accelerating innovation in the general illumination sector.
Related Standards
IEC 63146:2019 references and aligns closely with multiple international documents, notably:
- ANSI C78.374-2015: American National Standard for LED package specification sheets focused on general illumination, adapted within IEC 63146 with tailored deviations.
- IPC/JEDEC J-STD-020E: Industry standard for moisture/reflow sensitivity classification referenced for LED package handling requirements.
- IEC Electropedia and ISO Online Browsing Platform: Authoritative sources for terminology related to electrotechnology ensuring consistent definitions.
Stakeholders should consult these standards to ensure full compliance with related requirements and facilitate coherent documentation across multiple regions and markets.
