Ceiling system

Abstract

A ceiling system includes a supporting structure having a plurality of main runners made of an electrically conductive material. The main runners are arranged such that a first space is formed between at least one main runner and a first adjacent main runner and a second space is formed between the at least one main runner and a second adjacent main runner. An electric device is supported by the main runners and is arranged in the first or second space. A power source is arranged to apply an electric voltage between the main runners. The electric device includes connectors that are in electric contact with the main runners such that the electric device is powered by the applied electric voltage.
