Color tunable light with zone control
First Claim
Patent Images
1. A lighting system, comprising:
- a tunable array of zonal lighting devices providing a plurality of lighting zones, wherein each zonal lighting device corresponds to an independent lighting zone and each zonal lighting device is configured for independent color control and independent white color correlated temperature (CCT) control; and
a controller configured to;
receive one or more commands to implement one or more zone adjustments, wherein the one or more commands comprise;
an indication of the independent lighting zone of the plurality of lighting zones to adjust; and
an indication of a zone-specific white CCT value independent from one or more color values, wherein the zone-specific white CCT value corresponds to a CCT value of a camera sensor; and
control the plurality of lighting zones by providing one or more zone control signals, corresponding to the one or more commands, to the tunable array of zonal lighting devices to implement the one or more zone adjustments.

Abstract
A lighting system and method features full gamut color and white color correlated temperature (CCT) control of independently controlled zones. Each zone may be tuned to any color and/or white CCT. The result is a lighting system and method with a light-emitting face having zones of different colors and intensities that may be independently controlled in real time. The lighting system and method enables improved lighting effects for film, television, and still photography as compared to traditional panel lights that are uniform in color over the entire emission surface.
