Without a performance standard like IEC 62384, two LED drivers with identical specifications could behave entirely differently under real-world conditions. Here is why compliance with this standard matters:
LED drivers are energy conversion devices. IEC 62384 provides a specific formula for efficiency (η): [ η = \frac\textOutput Power (W)\textInput Power (W) \times 100% ] The PDF contains detailed tables of minimum efficiency levels for different topologies (buck, boost, flyback).

Title: DC or AC supplied electronic control gear for LED modules — Performance requirements
IEC 62384:2020 (Edition 2.0) defines the performance requirements for DC or AC supplied electronic controlgear used with LED modules, supporting supplies up to 1,000 V. The standard establishes mandatory benchmarks for output stability, startup time, and power factor verification for constant voltage or current drivers.

The IEC 62384 is an international performance standard for electronic control gear (LED drivers) used with LED modules. It defines how these devices should function to ensure reliability and compatibility in lighting systems.
While the full standard must be purchased directly from the IEC Webstore or authorized distributors like iTeh Standards, the following features and requirements are typically outlined in the document: Core Features of IEC 62384
Operational Scope: Specifies requirements for drivers operating on DC supplies up to 250V and AC supplies up to 1,000V (50Hz or 60Hz).
Performance Classification: Classifies control gear based on load (single value vs. variable) and output type (stabilized voltage or stabilized current). Electrical Characteristics:
Output Parameters: Defines starting and connecting requirements, as well as voltage and current stability during operation.
Power Quality: Sets standards for Total Circuit Power, Circuit Power Factor ( ), and harmonic limits.
Surge Capability: Addresses voltage surges during switching to protect connected LED modules.
Safety & Marking: Lists mandatory markings (e.g., power factor, temperature limits) and optional markings (e.g., dimming suitability) that must appear on the device or in technical catalogs.
Environmental & Endurance Testing: Includes "Operational tests for abnormal conditions" and endurance tests to ensure long-term reliability under thermal stress. Relationship to Other Standards
IEC 61347-2-13: While IEC 62384 focuses on performance, IEC 61347-2-13 covers the safety requirements for the same LED control gear.
IEC 62031: The performance requirements in 62384 are specifically designed for control gear used with LED modules defined by IEC 62031. Latest Version
The current version is IEC 62384:2020 (Edition 2.0), which replaced the original 2006 edition and its 2009 amendment. You can view a free sample preview of the standard's table of contents and introduction via iTeh Standards. IEC-62384-2020.pdf - iTeh Standards
