How To Guide: Capturing Measurement Data for Lighting Design

Lighting designers and engineers need precise detail about the luminance, chromaticity, and other performance characteristics of light sources such as LEDs. This How-To-Guide explains the measurement metrics for light source characterization, and discusses methods to  capture the key metrics including spectrometers, photometers, and colorimeters, used alone or in combination with goniometric systems. It compares methods of generating ray sets to ensure both the greatest accuracy and fastest measurement time, and describes various data visualizations to help users understand the performance of LEDs and other small light sources.
