Systems and methods for controlling color temperature
First Claim
1. A method for automated control of a plurality of lighting loads, each lighting load installed in one of a plurality of spaces, the method comprising:
- identifying a first inferred use of a first space of the plurality of spaces;
identifying a second inferred use of a second space of the plurality of spaces; and
generating a command configured to cause a cooler lighting effect for the first space based on the first inferred use;
generating a command configured to cause a warmer lighting effect for the second space based on the second inferred use;
automatically controlling the plurality of lighting loads to maintain the cooler lighting effect in the first space based on the command configured to cause the cooler lighting effect for the first space; and
automatically controlling the plurality of lighting loads to maintain the warmer lighting effect in the second space based on the command configured to cause the warmer lighting effect for the second space.

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.
