- 6. The hanger bracket of claim 5 wherein each of said rail gripping structures is in the form of forward facing U-shaped grips on opposite lateral edges of one of said hanger strips, said U-shaped grips being sized to fit over a mounting rail of a grid ceiling system.
- 7. The hanger bracket of claim 6 wherein said gripping structure is formed by a tab laterally extending from each lateral edge of one of said hanger strips, said tab having upper and lower forward extending arms which form said forward facing U-shaped grips.
- 8. The hanger bracket of claim 5 wherein said hanger strips each include an upper channel shaped portion having inwardly extending sidewalls which overlap when the hanger strips are joined together, and wherein said rail gripping structure is provided by complimentary cut-outs in the sidewalls of said hanger strips which form a rail gripping channel in the bracket body of the hanger bracket.
- 9. A load-bearing hanger bracket assembly for suspending a lighting fixture with an electrical feed from on-grid and off-grid locations within a grid ceiling system having a T-bar grid formed by connected T-bar members to which accessory mounting rails can optionally be attached and having ceiling tiles supported by the T-bar grid, said hanger bracket assembly comprisingan elongated bracket body having a base end, a top end, and at least one load wire attachment point, an electrical junction box attached to the said bracket body, a lighting fixture attachment element projecting from the base end of said bracket body, a first attachment structure at the base end of said bracket body for attaching the hanger bracket assembly to a T-bar member of a grid ceiling at a selected location along said T-bar member, and a second attachment structure on said bracket body above said first attachment structure for attaching the hanger bracket assembly to a mounting rail connected between T-bars of the grid ceiling system at a selected location along the mounting rail, whereby the hanger bracket assembly can be used to hang a lighting fixture from a T-bar member of the ceiling grid or from a mounting rail attached between T-bar members in order to place the lighting fixture and an electrical feed thereto through said junction box at desired on-grid and off-grid locations within the grid ceiling system.
- 10. The load-bearing hanger bracket assembly of claim 9 wherein said junction box has a bottom wall and wherein the hanger bracket assembly further comprises a female plug connected to the bottom wall of said junction box, said female plug having a downwardly facing plug end for receiving a male plug of a power cord of a lighting fixture suspended from the hanger bracket assembly.
- 11. The load-bearing hanger bracket assembly of claim 10 further comprising a canopy for covering a ceiling tile of the grid ceiling system at the location of the hanger bracket assembly, said canopy having a first opening for permitting the lighting fixture attachment element of the bracket body to project therethrough, and a second opening sized to permit the male plug of a lighting fixture power cord to plug into the plug end of the female plug connected to said junction box next to the point of suspension of the lighting fixture.
- 12. The hanger bracket assembly of claim 9 wherein the bracket body of said hanger bracket assembly has lateral edge portions and wherein said second attachment structure includes a rail gripping structure on each lateral edge portion of said bracket body for gripping a mounting rail of a grid ceiling system.
- 13. The hanger bracket assembly of claim 12 wherein said bracket body is comprised of two opposed hanger strips having shaped base ends for capturing a T-bar member of a grid ceiling system thereby providing a first attachment structure, and is further comprised of fastening means for joining said opposed hanger strips together and wherein said second attachment structure is provided on at least one of the hanger strips forming said bracket body.
- 14. A hanger bracket assembly for suspending a lighting fixture with a plug-in electrical feed from a grid ceiling system having a T-bar grid formed by connected T-bar members, said hanger bracket assembly comprisinga bracket body having a base end and at least one load wire attachment point, an electrical junction box attached to the bracket body, said electrical junction box having a bottom wall proximate to the base end of said bracket body, a female plug connected to the bottom wall of said junction box, said female plug having a downwardly facing plug end for receiving a male plug of a power cord of a lighting fixture suspended from the hanger bracket assembly, a lighting fixture attachment element projecting from the base end of said bracket body, and an attachment structure on said bracket body for attaching the hanger bracket assembly to a grid ceiling.
- 15. The hanger bracket assembly of claim 14 further comprising a canopy for covering a ceiling tile of the grid ceiling system at the location of the hanger bracket assembly, said canopy having a first opening for permitting the lighting fixture attachment element of the bracket body to project therethrough, and a second opening sized to permit the male plug of a lighting fixture power cord to plug into the plug end of the female plug connected to said junction box next to the point of suspension of the lighting fixture.
- 16. A method of electrically connecting lighting fixtures to a drop ceiling comprisingproviding electrical outlets at pre-selected lighting fixture suspension locations above the drop ceiling wherein each of said electrical outlets has a female plug having a downwardly facing plug end extending through the drop ceiling next to a suspension location for the lighting fixtures, wiring the electrical outlets so as to electrify same, hanging lighting fixtures from the drop ceiling having power cords with a male plug end of sufficient length to reach the ceiling, and plugging the male end of the power cords of the lighting fixtures into the female plugs of the prewired electrical outlets above the drop ceiling next to a suspension location of the lighting fixtures.
- 17. The method of claim 16 wherein a canopy is placed over the suspension location of each lighting fixture having an electrical outlet for providing a clean interface between the ceiling and the lighting fixture suspension and electrical connection, said canopy having an opening for receiving the male plug of the fixture's power cord.
- 18. The method of claim 17 wherein an array of pre-wired electrical outlets is provided above said drop ceiling to permit lighting fixtures to be moved to different locations on the ceiling without the need to rewire.
