Abstract: Lighting systems and devices offer dynamic control or tuning of a color characteristic, e.g. color temperature, of white light. The exemplary lighting systems and devices are used for general lighting applications that utilize solid state sources to pump remotely deployed phosphors. Two or more phosphors emit visible light of different visible spectra, and these spectra are somewhat broad, e.g. pastel, so that combinations thereof can approach white light temperatures including points along the black body curve. Independent adjustment of the intensities of electromagnetic energy emitted by the solid state sources adjusts levels of excitations of the phosphors, in order to control a color characteristic of the visible white light output of the lighting system or device.

Abstract: A device powered by solar or wind energy that produces multicolored lighting effects by virtue rotation or movement caused by air currents or the wind. Solar cells or a electromechanical generator produce electrical energy that stored through a control circuit for use at nighttime to power a number of light emitters. Air currents induce movement of the light emitters, or movement of the entire energy storage system, with the resulting visual effect of intermixing and changing colors as the rotation or movement varies in response to the force of the air currents.
