EN 13201 2 Photometric Testing of Road Lighting Performance
The European Standard EN 13201-2 outlines the requirements and procedures for photometric testing of road lighting performance. This standard is crucial for ensuring that road lighting meets safety, visibility, and energy efficiency requirements in diverse environmental conditions. The primary purpose of this test is to evaluate the light distribution characteristics of luminaires used on roads, ensuring they meet specified criteria regarding uniformity, glare, and overall performance.
The testing process involves precise measurements using a photometer and integrating sphere setup. Specimens are typically mounted on a rotating platform allowing for 360-degree rotation around all axes, simulating real-world usage scenarios. The test conditions replicate typical road lighting environments, including variations in weather, temperature, and altitude. This ensures that the luminaire's performance is accurately assessed under realistic operating conditions.
EN 13201-2 specifies detailed procedures for measuring various parameters such as luminous intensity, distribution of light, color rendering index (CRI), and color temperature. These measurements are critical in determining whether a luminaire complies with the specified performance criteria set by this standard. Compliance with these standards is essential for road lighting manufacturers to ensure their products meet regulatory requirements while also enhancing safety and visibility on roads.
The testing process begins with careful preparation of the specimen, ensuring it is free from dust or debris that could affect measurement accuracy. Calibration of instruments prior to testing ensures reliable data collection. The luminaire is then mounted in a standardized position within the photometer setup. During testing, multiple readings are taken at different angles and distances to capture comprehensive light distribution information.
After completing all measurements, detailed reports are generated summarizing the results. These reports typically include graphical representations of light distributions along with numerical values for key parameters like CRI and color temperature. Compliance with EN 13201-2 is mandatory for manufacturers aiming to sell their products within the European Union or any other region adhering to these standards.
Understanding the importance of this standard goes beyond mere compliance; it reflects a commitment to road safety, environmental sustainability, and user comfort. By adhering to EN 13201-2, lighting manufacturers contribute significantly towards creating safer roads that enhance visibility during night-time driving conditions. This not only protects drivers but also pedestrians who rely on well-lit paths and crossings.
The standard's emphasis on glare control is particularly significant as excessive brightness can cause temporary blindness or discomfort for road users. Properly designed luminaires reduce this risk, contributing to safer travel experiences overall. Additionally, by focusing on energy efficiency through optimized light distribution patterns, EN 13201-2 helps promote sustainable practices within the lighting industry.
In summary, EN 13201-2 plays a vital role in ensuring that road lighting performs optimally under various environmental conditions. Through rigorous photometric testing procedures, it guarantees compliance with essential safety and performance criteria while promoting energy-efficient solutions for better road infrastructure development.
Why It Matters
The importance of EN 13201-2 cannot be overstated when considering its impact on road lighting design, installation, and maintenance. Proper photometric testing ensures that luminaires meet stringent quality standards, thereby enhancing visibility for drivers and pedestrians alike.
