Abstract:
1. A light control system having a processor for automatically rendering a desirable lighting atmosphere, at least partially abstractly defined by a data file, with a lighting system having a plurality of lighting modules including at least one ambient lighting module, at least one task lighting module, and at least one accent lighting module, the light control system comprising: a decomposition unit for decomposing the desirable lighting atmosphere in elementary light effects by analyzing the data file, wherein the elementary light effects comprise at least two of the following: ambient light effects, task light effects, and accent light effects, a classification unit for classifying the elementary light effects into at least a first set and a second set of light effects, wherein each of the first set and second set comprise one or more of the elementary light effects, and a coordination unit for coordinating a realisation of the at least first set and second set of light effects with the lighting system by determining and refining configuration settings of the plurality of lighting modules, wherein the coordinating of the realisation of the sets of light effects includes computing an initial estimation of configuration settings for realizing each of the sets of light effects with the lighting system, and gradually refining the configuration settings in a closed-loop control system by independently adjusting different time scales for the at least first set and second set of light effects; wherein the computing an initial estimation of configuration settings for realizing each of the sets of light effects with the lighting system includes: selecting the first set of light effects as first target, computing the configuration settings for the first target so that only performance indexes associated to light effects of the first target are evaluated and light modules of the lighting system, which are provided for light effects not contained in the first target, are switched off, selecting the second set of light effects as second target, and computing the configuration settings for the second target so that only performance indexes associated to light effects of the second target are evaluated, wherein the computed configuration settings for the first target and second target are applied to respective light modules of the plurality of lighting modules of the lighting system.
