Growth in OLED Lighting Demands New Metrological Traceability
Englischer Artikel von Dr. Tobias Schneider
The increasingly broad transition from incandescent light bulbs to OLEDs for general lighting poses new challenges to light measurement. OLEDs exhibit completely different and far greater variations in their spectral distribution. This variability does not support optimal measurements using established calibrations with standard illuminant A, due to different spectral sensitivities to errors in calibration and measurement.
Metrological traceability and good control over measurement uncertainties is the key to ensuring reliable, safe, efficient, consistent, and predictable performance of lighting products. Therefore, the ability to adapt metrological procedures and calibration concepts to OLED light sources is essential for our ability to shape the success of OLED technology.
