First Claim
Patent Images
1. A lighting system comprising:
- at least a first light source providing a first color of light and a second light source providing a second color of light;
control circuitry operatively coupled to the first and second light sources and being configured to control the first and second light sources relative to one another to provide a color point that is linearly controlled to approximate a non-linear target lighting behavior in the CIE 1931 color space.

Abstract
A lighting system includes at least first and second light sources providing first and second colors of light. Control circuitry is operatively coupled to the first and second light sources, and is configured to control the first and second light sources relative to one another to provide a color point that is linearly controlled to approximate a non-linear target lighting behavior in the CIE 1931 color space.

11. A control system for controlling intensity of a lighting system that includes at least a first light source providing a first color of light and a second light source providing a second color of light to provide a color point that is linearly controlled in the CIE 1931 color space, the control system comprising:
-
power supply circuitry coupled to the first and second light sources for delivering power to the first and second light sources; and a controller coupled to the power supply circuitry to control intensities of the first and second light sources, the controller connected to receive a first control signal to adjust the intensity of the first light source and a second control signal to adjust the intensity of the second light source. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A control system for controlling intensity of a lighting system that includes at least a first light source providing a first color of light and a second light source providing a second color of light to provide a color point that is adjusted by control inputs, the control inputs comprising:
-
at least a first control input that controls an intensity of the first light source proportional to the first control input; and at least a second control input that controls an intensity of the second light source inversely proportional to the second control input. - View Dependent Claims (22, 23, 24)
