Abstract

A wiring and connection management system is disclosed. The system comprises a set of power distribution members that are attached to a substrate and are connected together, forming a power grid to distribute power across the substrate. The members include a number of connectors disposed at regular intervals along their lengths. Corresponding sets of cables and connectors on the substrate convey power from the members to areas on the substrate where power is desired. The substrate may be, for example, a shelving unit. The system provides a robust, flexible source of power that is easily installed with minimal training and is also easily maintained.

First claim

What is claimed is:

1. A wiring and connection management system, comprising:
a power supply;
a first elongate, at least semi-rigid printed circuit board (PCB) having first power and ground conductors connected to the power supply, the first PCB adapted to be attached to a first area of a structure so as to extend in a first direction along the structure;
one or more second elongate, at least semi-rigid PCBs adapted to be attached to the first area of the structure proximate to the first PCB so as to extend in a second direction along the structure, the second direction being different than the first direction, the one or more second PCBs having second power and ground conductors that are adapted to be electrically connected to the first power and ground conductors of the first PCB;
first sets of connectors mounted directly on the one or more second PCBs and connected to the second power and ground conductors; and
second sets of connectors electrically connected to the first sets of connectors, the second sets of connectors being positioned, structured, and adapted to bridge between the first area of the structure and a second area of the structure so as to provide power connection points along the second area of the structure.

2. The wiring and connection management system of claim 1 , further comprising at least one set of LED light engines adapted to be mounted on the second area of the structure and connected, at least indirectly, to the second sets of connectors to draw power.

3. The wiring and connection management system of claim 1 , wherein the first sets of connectors are surface-mount connectors mounted on the one or more second PCBs.

4. The wiring and connection management system of claim 1 , wherein within individual ones of the first sets of connectors, some of the connectors have different orientations than others of the connectors.

5. The wiring and connection management system of claim 1 , wherein the first PCB and the one or more second PCBs are arranged in a grid relative to one another, with the first and second directions being at least substantially orthogonal to one another.

6. The wiring and connection management system of claim 1 , wherein the first PCB comprises at least two semi-rigid PCBs electrically connected together.

7. The wiring and connection management system of claim 1 , wherein at least some of the one or more second PCBs comprise at least two semi-rigid PCBs electrically connected together.

8. The wiring and connection management system of claim 1 , wherein the first and second PCBs are attached to the substrate with magnets or adhesives.

9. The wiring and connection management system of claim 1 , wherein the first area of the structure is hidden relative to the second area of the structure.

10. The wiring and connection management system of claim 9 , wherein the structure comprises a gondola shelving unit.

11. The wiring and connection management system of claim 10 , wherein the first area of the structure comprises a reverse side of a rear wall of the gondola shelving unit.

12. The wiring and connection management system of claim 11 , wherein the second area of the structure comprises a front side of a rear wall of the gondola shelving unit.

13. The wiring and connection management system of claim 1 , wherein the first PCB comprises a third set of connectors mounted directly on the first PCB, the third set of connectors being electrically connected to the first power and ground conductors.

14. The wiring and connection management system of claim 13 , further comprising cables connecting between the third set of connectors on the first PCB and the first sets of connectors on the one or more second PCBs.

15. A power and lighting system, comprising:
a plurality of at least semi-rigid printed circuit boards (PCBs) each of the PCBs having
a thin, elongate, rectangular shape,
a plurality of conductors defined on metallization layers of the PCBs, at least some of the plurality of conductors being adapted to transmit power,
a plurality of connectors mounted directly on one side of the PCBs along their lengths, the connectors being electrically connected to the conductors, and
attachment structure on a side opposite the plurality of connectors;

a plurality of cables adapted to connect between the connectors of respective ones of the plurality of PCBs;
at least one light-emitting diode (LED) light engine electrically connected to one of the plurality of PCBs; and
a power supply directly electrically connected to at least one, but fewer than all, of the PCBs via the plurality of connectors;
wherein the plurality of PCBs are adapted to attach directly to a substrate using the attachment structure to form an electrical distribution network to distribute power from the power supply to the at least one LED light engine.

16. The power and lighting system of claim 15 , wherein the attachment structure comprises adhesives or magnets.

17. The power and lighting system of claim 15 , wherein the power distribution network comprises a power distribution grid.

18. The power and lighting system of claim 15 , wherein the electrical distribution network is provided on a hidden portion of the substrate and the at least one LED light engine is indirectly electrically connected to the one of the plurality of PCBs via a connector that bridges between the hidden portion of the substrate and an area in which the at least one LED light engine is installed.

19. The power and lighting system of claim 15 , wherein the plurality of connectors comprise surface-mount connectors.

20. The power and lighting system of claim 15 , wherein the electrical distribution network also provides control signals.

21. The power and lighting system of claim 15 , wherein some of the plurality of connectors have different orientations than others of the plurality of connectors.

22. A lighted shelving unit, comprising:
an upright support structure;
one or more shelves connected to the upright support structure;
one or more LED light engines associated with at least one of the one or more shelves; and
an electrical distribution network supplying the one or more LED light engines with power, the electrical distribution network comprising
