Canopy for a modular lighting system
View Patent ↗A modular lighting system for providing light in various areas includes one or more canopies, a set of buses, a set of hangers for supporting the bars from canopies and, optionally other supports, a set of pendants with light emitting elements and a set of hangers for supporting the pendants from the bars. The bars include two segments with conductive rails disposed or imbedded in their inner surfaces. The hangers have one or two rods and bases shaped and sized for mounting on the bars with the rods contacting the conductive rails. A canopy with ferrules is used to attach the system to the ceiling or other structural surface. The canopy includes a cup and ferrules extending through the cup wall and supporting hangers attached thereto. The ferrules further provide electric power to the hangers.
1. A lighting system comprising:
a canopy including a power source;
a plurality of bars disposed horizontally;
a plurality of bar hangers configured to support said bars; and
a plurality of pendant hangers adapted to support said pendants from said bars;
wherein said bars and hangers cooperate to conduct said electric current from said power source to said pendants;
at least one bar hanger including a first head having a horizontal wall, two outer walls extending perpendicularly to said horizontal wall and two metallic clips extending from said horizontal wall between said outer walls and at least one rod made of a conductive material being electrically connected to one of said clips, said rod extending upwardly from said first head;
wherein each bar includes two bar segments disposed equidistantly with respect to each other and defining a space with respective top and bottom openings, and electrically conductive rails attached to said power bar segments, said rails being disposed in said space; said first head of said hanger being attached to one of said bars with said outer walls being disposed outwardly adjacent to said bar segments and said clips extending between said bar segments through said top opening, with said clips forming interference fits with said bars to provide electrical connection between said clips and rails and to support said bar from said hanger;
wherein said canopy is connectable to a power source, said canopy including a housing, at least one ferrule, said ferrule including an upper portion adapted to be connected to a wire receiving power and a lower portion including a sleeve extending through said housing and in electrical contact with said upper portion, said sleeve being formed with a hollow aperture open from the bottom to receive the rod of the one hanger, said ferrule being configured to contact the rod electrically and support the rod.
2. The system of claim 1 wherein said bars are linear and are interconnected to form a linear configuration extending in one direction.
3. The system of claim 1 wherein said bars are linear and are interconnected to form a linear configuration extending in two directions.
4. The system of claim 3 wherein at least some of said bars are interconnected end-to-end.
5. The system of claim 3 wherein at least some of said bars are connected to each other at one end to form a star configuration.
6. The system of claim 1 wherein at least one of said bars is suspended by a bar hanger from another one of said bars.
7. The system of claim 1 wherein at least one of said bars is parallel to another of said bars.
8. The system of claim 1 wherein at least one of said bars is perpendicular to another of said bars.
9. The system of claim 1 wherein each bar is supported by said canopy.
10. The system of claim 1 wherein one of said bars is supported by said canopy and another of said bar is supported by a hanger extending to a structural member.
11. The system of claim 10 wherein said plurality of bars includes a first bar having a first section connected to said first canopy and a second section connected to said second canopy, said first and second sections being electrically insulated from each other.
12. The system of claim 1 comprising a first and a second canopy, each canopy being connected to a power supply.
13. The system of claim 12 wherein said plurality of bars includes a first set of bars electrically connected to said first canopy and a second set of bars connected to said second canopy.
