Color temperature tuning
First Claim
1. A lighting system comprising:
- a) one or more LED light fixtures, each comprising at least two different sets of LED arrays that emit different output spectra and that include a component of white light, wherein the different output spectra combine to produce a combined output light intensity and a combined output light color temperature;
b) a control unit coupled to the one or more LED light fixtures for controlling power to the one or more LED light fixtures;
c) one or more control interface devices coupled to control unit for independently controlling the combined output light intensity and the combined output light color temperature.

Abstract
An advance control LED lighting system is disclosed. The lightings system includes LED light fixtures with sets of different white LED arrays that emit different output spectra. The system includes a control unit for adjusting relative intensities of light outputs from the different sets of white LED arrays as well as the combined intensity of light output from the different sets of white LED arrays to produce ranges combined output light intensities and the combined output light color temperatures. Preferably the control unit includes a wireless transmitter for receiving and processing input control signals from a remote control interface device, such as a smart-phone or computer. The system also includes sensors coupled to the control unit for automatically adjusting one or more of the combined output light intensity and the combined output light color temperature based on a measured or detected condition.
