EN 62493-2015 is an international technical standard developed by the International Electrotechnical Commission (IEC). It is titled "Lighting flicker measurement - Part 1: Definitions and requirements for flicker meters" and provides guidelines and specifications for measuring flicker in lighting systems. Flicker refers to the rapid fluctuation of light intensity that may cause visual discomfort, eyestrain, and even health issues in some individuals.
The Importance of Flicker Measurement
Flicker measurement plays a crucial role in ensuring the quality and performance of lighting installations. By quantifying and assessing flicker levels, EN 62493-2015 enables manufacturers, designers, and users to evaluate and compare different lighting products and systems. It helps to identify potential issues, mitigate risks, and ensure lighting systems meet the necessary standards and recommendations for safe and comfortable use.
Key Requirements and Definitions
EN 62493-2015 defines various parameters and metrics that are essential for flicker measurement. These include:
Flicker severity: A value that indicates the degree of flicker present in a lighting system.
Flicker index: A calculation that determines the ratio between the high-frequency components and the total ripple amplitude of the measured light signal.
Frequency ranges: The specified frequency bands within which flicker measurements should be conducted.
Flicker measurement devices: The technical requirements and characteristics of flicker meters used for accurate measurements.
These requirements help establish a standardized approach for evaluating and comparing flicker levels in different lighting installations and products.
Conclusion
EN 62493-2015 provides a comprehensive framework for flicker measurement in lighting systems. By adhering to its guidelines and requirements, manufacturers and users can ensure the quality, safety, and comfort of lighting installations. Flicker measurement helps identify potential issues, select suitable lighting products, and create optimal lighting conditions for various applications. By addressing the issue of flicker, EN 62493-2015 contributes to better visual experiences and improved overall well-being.
