IEC 60747-5-6:2016

Overview

IEC 60747-5-6:2016 is an international standard published by the International Electrotechnical Commission (IEC) that focuses on semiconductor optoelectronic devices, specifically light emitting diodes (LEDs). This standard establishes the terminology, essential ratings, characteristics, measurement methods, and quality evaluation criteria for LEDs designed for general industrial applications such as signals, controllers, and sensors. It excludes LEDs intended for lighting applications.

The document provides comprehensive guidelines applicable to various types of LEDs, including LED packages, flat illuminators, numeric and alphanumeric displays, dot-matrix displays, and infrared-emitting diodes. The edition released in 2016 represents a significant technical revision, replacing previous IEC standards on LEDs and updating testing procedures and terminology to reflect advances in optoelectronic technology.

Key Topics

• Terminology and Definitions
  The standard defines critical terms related to LED characteristics, radiation measurement, and photometric quantities to ensure consistent understanding across the industry.

• Absolute Maximum Ratings
  Specifies the maximum permissible electrical and thermal limits for LEDs to maintain safe and reliable operation.

• Electrical and Optical Characteristics
  Details parameters such as forward and reverse voltage, differential resistance, reverse current, and luminous flux vital for LED performance benchmarking.

• Measurement Methods
  Comprehensive procedures cover measurement of key parameters including:

  • Forward/reverse voltage and current
  • Capacitance and differential resistance
  • Junction temperature and thermal resistance
  • Response time and frequency response
  • Luminous flux, radiant power, luminous and radiant intensity
  • Luminance, emission spectrum, peak wavelength, and spectral bandwidth
  • Chromaticity and directional characteristics

• Quality Evaluation
  The standard emphasizes quality control through precise testing, ensuring LEDs meet industrial application requirements.

Applications

IEC 60747-5-6:2016 supports the design, testing, and quality assurance of LEDs used in an extensive variety of industrial equipment:

• Signal Indicators
  Used in control panels and machinery to provide status indication through LEDs that comply with defined electrical and optical standards.

• Controllers and Sensors
  Ensures consistent performance for LEDs integrated into control systems and sensor devices requiring reliable optoelectronic emission.

• Display Technologies
  Applied for numeric, alphanumeric, and dot-matrix LED displays, improving measurement accuracy and functional consistency.

• Infrared Communication and Sensing
  Defines specifications for infrared-emitting diodes, facilitating their use in remote controls, data transmission, and detection systems.

This standard aids manufacturers and engineers in developing LEDs that deliver robust, reproducible performance for industrial applications while excluding general lighting products for which separate standards apply.

Related Standards

IEC 60747-5-6:2016 is part of a broader family of IEC standards covering semiconductor optoelectronic devices. It works in conjunction with:

• IEC 60747-5-4, -5, and -7
  Other parts addressing different types of optoelectronic devices and related measurement and testing practices.

• IEC 60747-5-1, -2, and -3 (Superseded)
  Previous editions related to LEDs replaced by the 2016 revision to harmonize terminology and testing procedures.

For lighting applications involving LEDs or integrated LED modules, separate specialized standards apply, ensuring comprehensive coverage across all LED use cases.
