Abstract:
1. A method for operating an optical system having a plurality of light sources and outputting combined light, wherein the plurality of light sources have different spectral outputs relative to an input setting which represents a desired characteristic of the combined light, wherein the optical system includes a color sensor for measuring characteristics of the combined light, the method comprising the steps of: (a) receiving a user input which maps color to a predefined coordinate space in at least two colors; (b) transforming the user input to a set of expected color component values representing expected measurements of the color sensor had the plurality of light sources output light corresponding to the user input in actual operation; (c) outputting control signals for operating the plurality of light sources based on the set of expected color components; (d) driving the plurality of light sources based on the control signals; and (e) adjusting the control signals based on measurements of the spectral outputs received from the color sensor following step (d).
