1. A method, comprising:
- receiving data encoded with a color point; and
converting the data to a plurality of control signals, wherein each of the plurality of control signals controls a luminous flux of one of a plurality of light sources relative to other ones of the plurality of light sources, wherein a combined output of the plurality of light sources generates the color point, wherein the data is further encoded with a total luminous flux value;
converting the data to modify the plurality of control signals, wherein each of the plurality of control signals controls an absolute luminous flux of one of the plurality of light sources, wherein the combined output of the plurality of light sources generates the total luminous flux value, wherein converting the data to modify the plurality of control signals comprises;
decoding the data into data representative of the color point and data representative of the total luminous flux value; and
separating the data representative of the color point into a first coordinate and a second coordinate, wherein the first coordinate and the second coordinate correspond to the color point on a standard color chart.
