  • Patent number: 8723450
    Abstract: Systems and methods for controlling the spectral content of the output of a light fixture. The method of one embodiment includes driving the output of a light fixture to a target color and controlling the spectral content of the output of the light fixture. For example, a desired color is inputted using a color control methodology. A set of light source output intensity values that produce the desired color are identified, and then the light sources are driven to the identified output intensity values. A user is able to control the spectral content of the output of the light fixture by modifying the output intensity value of one or more of the light sources. After modifying the output intensity values, the color control and matching technique is used to identify a new set of output intensity values that maintain the previous target color but incorporate the changes in spectral content.
