Track-based lighting system

A lighting system comprising:

• a plurality of power tracks lying in a first plane, each power track being formed from a rigid material and carrying one or more power lines for carrying power and comprising an upper surface configured for suspension of the power track from a ceiling;
• and
• one or more lighting panels for emitting light, each lighting panel being:
• mechanically coupled to a respective set of power tracks, comprising at least two of the plurality of power tracks, to thereby be structurally supported by the respective set of power tracks;
• and
• configured to draw power from the one or more of the power lines,
• wherein each power track comprises a housing defining a cavity having an interior surface of a wall facing the cavity and having an opening facing in a direction away from the upper surface of the power track,
• wherein the one or more power lines are carried on the interior surface within the cavity of the housing, the cavity of the housing and one or more power lines being configured for the placement and powering of an electrical device,
• each power track comprises electrical contacts on the upper surface, the upper surface being configured for facing the ceiling and mechanically coupling to the lighting panel, and the electrical contacts being configured, for electrically coupling to the lighting panel;
• and
• each lighting panel is configured to rest upon the upper surface of each power track of the respective set of power tracks to thereby mechanically couple the lighting panel to the respective set of power tracks.
