ASTM E2837 Outdoor Lighting Flicker Testing of High Brightness LED Systems
The ASTM E2837 standard provides a method for measuring the flicker in outdoor lighting systems, particularly those utilizing high brightness Light Emitting Diode (LED) technology. This testing is crucial for ensuring compliance with international standards and meeting the quality expectations of end-users such as municipalities, public utilities, and commercial establishments.
Outdoor LED lighting faces unique challenges due to environmental factors like temperature fluctuations, humidity, and exposure to UV radiation. These conditions can influence the performance stability of LED systems, making flicker testing an essential step in ensuring consistent light output over time. Flicker is not only a visual annoyance but also a potential health concern for individuals sensitive to photic stimuli.
The ASTM E2837 test aims to quantify the flicker effect by measuring the frequency and duration of changes in apparent brightness, expressed as a percentage. This measurement helps determine whether the light source meets specified thresholds that define acceptable flicker levels. Flicker can occur due to various factors including phase-controlled dimming circuits, power supply instability, or inherent characteristics of LED materials.
The testing process involves placing specimens under controlled environmental conditions that mimic real-world outdoor scenarios. Specimens are then subjected to specific light output levels and frequencies while monitoring for any deviations in brightness. The apparatus used includes specialized flicker meters capable of detecting even the slightest variations in light intensity.
Compliance with ASTM E2837 is important because it ensures that high brightness LED systems meet stringent quality standards set by regulatory bodies worldwide. Non-compliant products may cause discomfort or health issues, leading to increased maintenance costs and potential liability for manufacturers and installers.
To perform ASTM E2837 testing accurately requires specialized knowledge and equipment. Laboratories like Eurolab possess the expertise and technology needed to conduct these tests reliably and consistently.
