Patent number: 8330373Abstract: 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.Type: GrantFiled: March 23, 2010Date of Patent: December 11, 2012Assignee: ABL IP Holding LLCInventors: David P.
