Abstract
Lighting devices and methods utilize multiple independently controllable groups of solid state light emitters of different dominant wavelengths, with operation of the emitter groups being automatically adjusted by processor(s) to provide desired illumination. Operation of the emitter groups may be further affected by sensors and/or user input commands (e.g., sound patterns, gesture patterns, or signal transmission). Operation may be adjusted to compensate for presence, absence, intensity, and/or color point of ambient or incident light. Presence of five or more groups of solid state light emitters provide desirable luminous flux, color point, correlated color temperature (CCT), color rendering index (CRI), CRI R9, and luminous efficacy characteristics of aggregate emissions over a wide range of CCT values, and may permit adjustment of vividness (e.g., relative gamut) and/or melatonin suppression characteristics for a selected color point or CCT.
