Understanding Performances
LED lighting systems are widely used in applications where brightness and color accuracy are critical to safety. Photometry plays a central role in evaluating LED performance because it measures light as it is perceived visually.
Intensity
The amount of light emitted in a given direction (Brightness).
Chromacity
The specific color characteristics of that light (Color Accuracy).
Why Testing Is Critical
Ensure minimum intensity for visibility
Verify color for signaling (Red/Green/Amber)
Avoid safety risks in traffic systems
Validate performance before release
Brightness
Led Intensity Testing
Intensity testing evaluates how much light an LED produces and how that light is distributed. Even small variations in output can affect visibility under different ambient lighting conditions.
Applications: Traffic signals, pedestrian signals, warning indicators.
Color Accuracy
Chromaticity Testing
Focuses on color characteristics. Variations can lead to confusion or failure to meet specifications. We evaluate whether products produce light within defined color boundaries.
Benefits: Compliance verification, quality assurance, consistency.
