Studying potential colour shifts in White LED’s while dimming in order to understand the measured aspects of correlated colour temperature (CCT) and other colour metrics.
The lighting industry relies on metrics to report, evaluate and predict how a fixture is going to perform. The general assumption and conventional wisdom is that LEDs do not change in CCT when dimmed unless they are warm-dim technology. Is this an assumption or reality? Information regarding CCT and other properties like SPD, CRI and CIE chromaticity coordinate values of LEDs, when they are dimmed, is not readily available. This study focuses on evaluating white LED’s when dimmed by evaluating the measured changes in advanced metrics like the TM-30, CIE chromaticity and CRI for different sources.
