Patent ID: 8324826

Claim:
A method for composing a lighting atmosphere from an abstract atmosphere description comprising the acts of: providing the abstract atmosphere description of the lighting atmosphere by describing the type of light with certain lighting parameters desired at certain semantic locations at certain semantic times, wherein a semantic location is a description of a location and a semantic time is a description of a time, transferring the abstract atmosphere description to a specific instance of a lighting system; compiling the abstract atmosphere description into an atmosphere model comprising a room layout dependent and lighting infrastructure independent description; replacing the certain semantic locations in the abstract description with physical locations in the room; replacing the certain semantic times in the abstract description with actual times; and/or replacing any semantic sensors in the abstract description with real sensors located in the room; rendering the atmosphere model to a target by removing of dynamics, time and switch or sensor dependencies from the atmosphere model and creating a snapshot of the lighting atmosphere at a certain point in time and given sensor readings at the certain point in time; mapping the target into actual control values for lighting devices of the specific instance of a lighting system; receiving parameters of the lighting devices and contributions of the lighting devices to a lighting at a certain physical location, calculating the actual control values for the lighting devices based on the received parameters and contributions and the target; receiving sensor values; controlling the lighting devices with a closed feedback loop or an open loop control based on the received sensor values.
