ＤＣ照明及び電力グリッド上の位置決定用の方法及びシステム

摘要

The present disclosure is directed to methods and apparatus for locating luminaires within a lighting system where multiple luminaires are located on a grid of DC power rails. The AC signal generator connects to each DC power rail and transmits an AC signal along each DC power rail in turn to luminaires that each compute their distance from the generator based upon the AC signal. The AC signal generator may similarly transmit and receive data communications with luminaires across DC power rails.
