What is IEC 62031:2018?

IEC 62031:2018 is an international standard that provides guidelines and requirements for the performance, testing, and safety of LED modules and LED circuits used in general lighting applications. This technical article aims to provide an in-depth understanding of the key aspects covered by the standard.

Scope and Application

The scope of IEC 62031:2018 includes LED modules with integrated control electronics and LED circuits with separate electronic control gear. It covers various aspects such as photometric, electrical, thermal, and reliability requirements. The standard applies to both AC and DC input voltage LED products that are intended for general lighting purposes.

By specifying the requirements for LED products, the standard ensures that manufacturers produce safe and reliable lighting solutions. It also helps users and regulators in assessing and comparing the quality and performance of different LED products available in the market.

Performance Requirements

The performance requirements outlined in IEC 62031:2018 cover several important parameters, including luminous flux, color rendering index (CRI), chromaticity, temperature dependence of light output, and more. These requirements help to ensure that LED products deliver consistent and reliable performance over their claimed lifetime.

The standard also sets limits for parameters such as flicker, stroboscopic effect, and power factor to address potential health and safety concerns. Additionally, it defines a method for measuring LED module efficiency, which allows users to evaluate the energy efficiency of different products.

Testing and Safety Considerations

IEC 62031:2018 specifies various test methods to assess the compliance of LED modules and LED circuits with the defined requirements. These tests verify the performance, electrical characteristics, thermal behavior, and other critical aspects of the products.

To ensure safety, the standard covers different aspects such as risk assessment, protection against electrical shock and fire hazards, and materials used in the construction of LED modules and circuits. It also addresses the need for proper labeling, marking, and user instructions to facilitate safe installation, operation, and maintenance of LED lighting systems.

Compliance with IEC 62031:2018 is essential for manufacturers, distributors, and end-users to ensure that the LED products they produce, sell, or use meet the necessary quality, performance, and safety requirements. By adhering to this standard, manufacturers can demonstrate their commitment to delivering reliable, energy-efficient, and safe LED lighting solutions to the market.
