The IEC 62384 standard is a critical international benchmark for the performance of electronic controlgear (commonly known as LED drivers). While other standards focus on safety, IEC 62384 ensures that the drivers operate efficiently and reliably, directly impacting the lifespan and quality of LED lighting systems.

The most current version is IEC 62384:2020, which replaces the previous 2006 edition and its 2009 amendment. Scope and Application

This standard specifies performance requirements for electronic controlgear used on DC or AC supplies up to 1,000 V (at 50 Hz or 60 Hz). It applies to drivers designed to provide: Constant Voltage or Constant Current. Controlgear for LED modules as defined in IEC 62031. iec 62384 pdf

Drivers with outputs whose frequency may deviate from the supply mains. Key Performance Requirements

The standard outlines several "type tests" (intended for design validation rather than production-line testing) to ensure operational quality:

Output Stability: During operation, the output voltage or current must not differ by more than ±10% from the rated values when supplied within 92% to 106% of the rated supply voltage.

Start-up Behavior: The output must reach within 110% of its rated value within 2 seconds of starting. Circuit Power Factor (

): The measured power factor must not be lower than the marked value by more than 0.05.

Total Circuit Power: At rated voltage, the total power (driver + module) must not exceed 110% of the manufacturer's declared value.

Abnormal Conditions: Drivers must withstand open-circuit and short-circuit conditions for 1 hour without damage. Significant Changes in the 2020 Edition

The 2020 revision introduced several technical updates to keep pace with evolving LED technology:

Extended DC Range: The DC supply range was increased from 250 V to 1,000 V.

Constant Light Output (CLO): New measurement rules for power factor were added for drivers with settable or non-constant outputs, such as those that compensate for LED lumen depreciation over time.

Module Capacitance Tests: The selection of test circuits is now based on the input capacitance of the LED module (typically using a 100 nF threshold) rather than the presence of logic circuitry.

Audio Frequency Deletion: Requirements for audio-frequency impedance were removed in this edition. Safety vs. Performance: IEC 61347-2-13 vs. IEC 62384

It is important to distinguish between these two frequently paired standards: Here is some information: What is IEC 62384

The IEC 62384 standard, titled "DC or AC supplied electronic controlgear for LED modules – Performance requirements," specifies the technical performance benchmarks for LED drivers. The latest version is IEC 62384:2020 (Edition 2.0), which replaces the original 2006 edition and its 2009 amendment. Core Purpose and Scope

This standard defines how electronic controlgear should perform when powering LED modules defined by IEC 62031.

Voltage Range: Applies to supplies up to 1,000 V (AC at 50/60 Hz or DC).

Control Type: Covers drivers designed for constant voltage or constant current output.

Relationship to Other Standards: It must be read in conjunction with IEC 61347-2-13, which covers the safety requirements for the same equipment. Key Performance Requirements

The standard outlines specific metrics that LED drivers must meet during testing: IEC 62384:2020

• Scanned copies: Often missing colored diagrams or are illegible.
• Old editions: A 2006 version will fail a modern Energy Star or ERP test.

Clause 6: Efficiency

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).
