Abstract
A lighting system including fixture lamps, e.g., ceiling mounted, and movable light sources, e.g., task lamps. The task lamps include illuminance sensors arranged to detect ambient light including light emitted by one or more fixture lamps and available daylight. Control data is generated based at least in part on the illuminance data. The resulting control data is transmitted from the task lamp to a fixture lamp and a window system so that it can be used to control the amount of light emitted by the fixture lamp and amount of daylight transmitted through the window system. This arrangement allows daylight harvesting while ensuring that the amount of light provided to workspaces (at which task lamps are located) is satisfactory.
