Advanced multi-channel illuminants consist of four or more strategically differentiated non-white LED illuminants. When simultaneously combined they can exhibit exceptional color fidelity, stability, efficacy, die area utilization, and more in contrast to systems of PC-white LEDs. They represent a fundamental forward-looking path in illumination – capable of fully addressing the limits of efficacy and spectral dynamics of human factors (temporal/circadian stimulus, color, intensity), imaging/sensors, and horticulture. The underlying properties of an optimized class of 5-channel illuminants are examined in contrast to systems of state-of-art phosphor-converted white illuminants. Factors including: color fidelity limits (CRI, R9, IES TM30-18 Rf for human eye, and CAM02-UCS deltaE's for camera sensor case) relative to white reference illuminants over broad CCT range (1100K - 10000K), die utilization, efficacy, die binning sensitivity, circadian stimulus minimization and maximization over CCT at specific lux levels, and short and long-term color stability are compared. (results summary forthcoming).
