Abstract
The present invention provides an illumination system enabling dynamic color control of the illumination produced by the system. The illumination system comprises light-emitting elements for producing illumination, and at least one detecting device which collects information relating to the illumination, which is inherently non-linear. The illumination system also integrates a computing system which receives, the information from the at least one detecting device and linearises this information using a multivariate function having a solution defining a hyperplane representing constant chromaticity for a given luminous intensity, and then determines a number of control parameters based on the information. The illumination system also integrates a controller for receiving the control parameters from the computing system and determining the control signals to be sent to the light-emitting elements in order to dynamically alter the characteristics of the illumination based on the collected information and the desired illumination result.
