Patent ID: 8731690

Claim:
A light system controller for controlling a lighting scene created with a lighting system comprising: a user interface for receiving at least one user input associated with a user-defined new lighting scene descriptor related to a descriptor word; processing means for setting the new user-defined lighting scene descriptor by modifying properties of an actual lighting scene created with the lighting system in accordance with the received user input and outputting an appropriate modification output; and a lighting system interface for receiving the modification output from the processing means and for outputting appropriate control signals for light sources of the lighting system for creating a new lighting scene in accordance with the user input; wherein a user-defined lighting scene descriptor includes a set of modifications of the characteristics of the light sources of the lighting system expressed as color space and brightness vectors, wherein the color space vector indicates an adjustment to be made to a color of light emitted by the light sources relative to a current color emitted by the light sources and the brightness vector indicates an adjustment to be made to a brightness of light emitted by the light sources relative to a current brightness of light emitted by the light sources; wherein the processing means are further adapted for modifying the properties of the actual lighting scene created with the lighting system in accordance with a cumulative color space vector and a cumulative brightness vector calculated based on vector addition of multiple color space and brightness vectors.
