Lighting control

A lighting control apparatus comprising:

• a control interface configured to connect to a lighting system comprising one or more luminaires for illuminating an environment, each luminaire comprising at least one lamp controllable to emit configurable illumination;
• a memory configured to store at least one set of configuration data for a group of lamps in the lighting system, the set of configuration data defining an initial lighting scene for rendering by the group of lamps;
• a scene controller arranged for controlling the group of lamps, via the control interface, to render lighting scenes;
• a detector configured to detect when at least one lamp of the group of lamps is emitting illumination that would disrupt the initial lighting scene by detecting when the at least one lamp of the group of lamps is uncontrollable by the scene controller, and via the control interface that the at least one lamp of the group of lamps has become unreachable, and determine at least one characteristic of the disruptive illumination by accessing in the memory a last-known illumination setting of the at least one lamp of the group of lamps;
• and
• a scene modifier configured to modify the set of configuration data based on the determined characteristic to account for the disruptive illumination, such that an overall illumination of the environment when rendering the modified scene at least approximately matches an overall illumination of the environment that would have been provided had it been possible to render the initial scene without the disruptive illumination;
• wherein the scene controller is configured to control one or more lamps of the group of lamps, via the control interface, to render a modified lighting scene defined by the modified set, wherein controlling the one or more lamps of the group of lamps comprises adjusting the illumination of the one or more lamps of the group of lamps other than the at least one lamp of the group of lamps which is uncontrollable by the scene controller.
