Overview

EN IEC 63403-2:2024 is the European adoption of the international standard IEC 63403-2:2024, developed by the International Electrotechnical Commission (IEC) and approved by CLC. This standard specifies the binning methods for LED packages used in horticultural lighting, ensuring consistent performance and quality in horticultural LED lighting systems. Binning is a crucial process that groups LEDs based on specific electrical and optical characteristics, optimizing their use for plant growth applications.

The standard provides clear guidelines on measuring and classifying LED properties such as forward voltage, photon flux, and chromaticity under controlled conditions to guarantee reliability and effectiveness in horticultural environments.

Key Topics

• Scope and Application
  EN IEC 63403-2:2024 focuses exclusively on the binning methods for LED packages designed for horticultural lighting, complementing Part 1 (Specification sheet) by IEC 63403-1.

• Measurement Conditions

  • Junction temperature for binning is set at 85 °C, either measured directly or extrapolated from 25 °C.
  • Binning currents are standardized and listed in a table covering currents from 30 mA up to 1800 mA, tailored to the LEDs’ intended application.
  • Pre-conditioning requires stabilizing LEDs at the target junction temperature prior to measurement.

• Binning Parameters and Methods

  • Forward Voltage Binning: Grouping LEDs in bins with voltage intervals not exceeding 100 mV to ensure electrical consistency.
  • Photon Flux Binning: Optical output is classified based on photon flux (expressed in µmol/s), essential for evaluating photosynthetically active radiation (PAR) critical to horticulture.
  • Chromaticity Binning:
    • Narrow-band emitters are binned according to centroid or dominant wavelength for precise spectral control.
    • Achromatic emitters are binned using chromaticity coordinates as defined by ISO/CIE 11664-1.

• Measurement Standards Referenced
  The standard references CIE 225:2017 for steady-state optical measurements and CIE 226:2017 for high-speed optical testing, ensuring accurate and standardized measurement practices.

Applications

• Horticultural Lighting Design
  Enables manufacturers and horticultural lighting designers to sort LED packages effectively, ensuring uniform spectral output and intensity tailored for optimized plant growth cycles.

• Quality Control and Manufacturing
  Assists LED producers in implementing reliable sorting procedures to guarantee product consistency, reduce variability, and match horticultural lighting specifications.

• Research and Development
  Supports R&D in horticulture-related lighting by providing a standardized framework for evaluating LED performance, promoting innovation in plant-optimized LED technology.

• Energy-Efficient Agriculture Solutions
  Encourages efficient use of LED lighting by binning LEDs to match crop-specific photosynthetic needs, thereby improving energy efficiency and crop yield in controlled-environment agriculture.
