According to an embodiment of the invention, a light management system (10) with automatic identification of light effects available for a home entertainment system (12), wherein the light management system (10) is adapted for - automatically composing a lighting scene from an abstract light experience description (14), which describes types of light effects at certain locations relative to the entertainment system, - automatically registering light effects controlled by the light management system (10) and being available for the home entertainment system (12), and - automatically integrating the registered light effects in the composition of the lighting scene. This allows to automatically identify light effects generated by light sources in a room and controllable by a light management system and make them available for a home entertainment system such as an amBX ® system.
Abstract:
The invention relates to composing a lighting atmosphere from an abstract description for example a lighting atmosphere specified in XML, wherein the lighting atmosphere is generated by several lighting devices, by automatically rendering the desired lighting atmosphere from the abstract description. The abstract description describes the type of light with certain lighting parameters desired at certain semantic locations at certain semantic times. This abstract atmosphere description is automatically transferred to a specific instance of a lighting system (14, 16, 18). The invention has the main advantage that it allows to create light scenes and lighting atmospheres at a high level of abstraction without requiring the definition of a lighting atmosphere or scene by setting the intensity, color, etc. for single lighting units or devices which can be very time consuming and cumbersome, particularly with large and complex lighting systems comprising many lighting devices.
