Lighting devices and/or systems offer dynamic control or tuning of color of light. The lighting systems utilize sources, such as solid state sources, to individually pump a number of different phosphors of types having relatively high degrees of color purity. The phosphor emissions, however, are still broader than the traditionally monochromatic color emissions of LEDs. The different phosphors can be independently excited to controllable levels, by individually controlled sources rated for emission of energy of the same spectrum. Adjustment of intensities of electromagnetic energy emitted by the sources independently adjusts levels of excitations of the phosphors selected to emit different colors of relatively high purity and thus the contributions of pure colors to the combined light output, for example, to enables color adjustment of the light output over a wide range of different selectable colors encompassing much of the gamut of visible light.

The present application generally relates to techniques and equipment for color correction of natural daylight. More particularly, the present application relates to color correction of daylight entering the interior of a structure to maintain a substantially constant color temperature over a period of time through deployment of an opto-luminescent material in a daylighting device. The color correction through deployment of an opto-luminescent material and/or color filter in a daylighting device preferably maintains high lumen intensity.
