The standard (officially titled "DC or AC supplied electronic controlgear for LED modules – Performance requirements") is the global benchmark for the performance of LED drivers. While safety is covered under other standards like IEC 61347-2-13, IEC 62384 focuses specifically on how well an LED driver operates, its efficiency, and its ability to maintain stable light output. Scope and Applicability
This standard specifies performance requirements for electronic controlgear used on DC or AC supplies up to (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
The standard requires manufacturers to accurately measure and declare the total power consumed by the combination of the controlgear and the LED module. This ensures energy efficiency claims are verified. 3. Power Factor (PF) The standard (officially titled "DC or AC supplied
Power factor measures how effectively the driver uses electricity. A low power factor wastes energy and strains the electrical grid. The standard defines acceptable power factor levels for different classes of equipment. 3. Supply Current Audio-Frequency Filter It applies to drivers designed to provide: Constant
Engineering firms often use enterprise access platforms like IHS Markit or IEEE Xplore.
Electronic control gear relies on high-frequency switching circuits, which can introduce unwanted harmonics back into the electrical network. High THD distorts the AC voltage waveform, potentially disrupting other sensitive electronics on the same circuit. The standard limits the allowable harmonic current emissions to protect grid stability. 4. Efficiency and Power Loss
