| Title: |
System and Method for Controlling the Spectral Content of an Output of a Light Fixture |
| 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.
