METHOD AND APPARATUS FOR OPERATING A GROUP OF LIGHTING FIXTURE NODES

摘要

Methods and apparatus for operating a group of lighting fixture nodes (10A-D) at a reduced power level are disclosed. In some versions of the methods a plurality of lighting fixture nodes in a group of electrically connected lighting fixture nodes may each be operated at a nominal fixture power level; a current draw across at least a test lighting fixture node of the lighting fixture nodes may be identified; and the extent to which to reduce power of each lighting fixture node may be determined as a function of the current draw across the test lighting fixture node.
