Systems and Methods for Controlling Color Temperature
First Claim
1. A system for controlling a plurality of lighting loads in a space responsive to an emergency mode, the system comprising:
- a plurality of load regulation circuits configured to adjust an intensity of a lighting load; and
a plurality of lighting loads, each lighting load of the plurality of lighting loads comprising a first discrete-spectrum light source adapted to emit light corresponding to a first color temperature and a second discrete-spectrum light source adapted to emit light corresponding to a second color temperature that is substantially different than the first color temperature, the lighting load configured to emit a composite light output characterized by a composite color temperature; and
wherein during an emergency mode, each of the plurality of load regulation circuits are configured to adjust the composite color temperature of their respective lighting loads to create at least one of an increasing or a decreasing color temperature along an indicated path.

Abstract
Controlling the color temperature of a composite light source including at least one discrete-spectrum light source is disclosed. For example, the color temperature of a composite light source including at least one discrete-spectrum light source may be determined and/or adjusted based on one or more of the ambient color temperature of a space, the actual temperature of the space, the relative brightness of the space, the occupancy of the space, a time clock, a demand response command (e.g., from an electrical utility), the absolute location of the composite light source, the location of the composite light source relative to other light sources, inputs from a camera or other external devices, the operation of appliances or other machines in the vicinity of the composite light source, media content being utilized in the vicinity of the composite light source, and/or other sensor inputs.
