| Title: |
Control System For an Illumination Device Incorporating Discrete Light Sources |
| 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.
