Spectrally tunable LED light engines and the metamer optimization tool (MOTO)

In this work, we show a spectrally tunable LED lighting system that uses the SPDs of the different channels of the light engine to optimize for different parameters, i.e. flux, illuminance, efficacy, CRI-Ri, TM30-15-Ri, Damage Potential, melanopic flux, PPF/YPF, CLA/CS, etc. Our results show how this tool and their associated methods can be used to design complex lighting applications in a meaningful and objective manner.
