Abstract:
1. A method of controlling an output of a light fixture, the light fixture including four or more light sources, the method comprising: receiving a first input parameter corresponding to a first color point within a color space; receiving a second input parameter associated with a desired intensity for the first color point; determining a white point based on a relationship between the second input parameter and the color temperature of a black-body radiator, the white point corresponding to a second color point within the color space; selecting a color temperature transform based on the white point; calculating a third color point within the color space based on the color temperature transform, the color temperature transform defining a relationship between the first color point and the third color point, the third color point being different than the first color point, and the third color point being different than the second color point; determining a respective light source output value for each of the four or more light sources based on the third color point; and driving each of the four or more light sources at the respective light source output value to produce the output of the light fixture.
