Choosing a Measurement System for LED Sources, Luminaires and Displays
With the excitement surrounding the emergence of LED lighting and displays it is becoming increasingly important to be able to measure the performance of LEDs and LED-based systems in accurate and meaningful ways. This is even more important as LEDs are increasingly used as an alternative to more traditional technologies. The intended purpose of the measurement - to inform development, to characterize or evaluate finished products, for production quality control, or for in-use performance assessment - determines the photometric and colorimetric quantities that are important to measure. This guide offers insight for choosing the best measurement system for LED sources, luminaires, and displays in order to acquire the most accurate data for these purposes.
