| Title: |
Systems and Methods for Controlling an Output of a Light Fixture |
| Abstract: |
Systems and methods for controlling an output of a light fixture. A light
fixture of one construction includes four or more light sources and is
configured to produce an output that mimics the color temperature changes
of an ideal black-body radiator based on one or more input parameters.
The input parameters correspond to, for example, a desired target color
and an intensity for the desired target color. A white point setting is
determined based on the one or more input parameters and a relationship
between the one or more input parameters and the color temperature of an
ideal black-body radiator. A color temperature transform is selected
based on the white point color temperature setting, and is used to
determine a color coordinate corresponding to a modified target color. A
set of light source output values corresponding to the modified target
color are identified, and the light sources are driven to the identified
output values.
