There exists a need for the design of light emitting diode (LED) luminaires which can deliver both visual and non-visual benefits of light to humans. In this work. we introduce an optimization approach based on spectral shaping for a minimalistic and practical design of a circadian-tunable multi-channel luminaire which also outputs white light with high quality and luminous efficacy o... https://www.spidertattooz.com/Veuve-Ambal-Rose-Cremant-de-Bourgogne-750ml/
