DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(11) FIG. 1 is an exploded view of the present invention. The assembly has a cover panel 21. The cover panel is mounted above the T track frame. The T-bar frame includes a right T-bar 26 parallel to a left T-bar 27, with a rear T-bar 28 parallel to a front T-bar 29. The T-bar frame supports the mounting bracket frame, and the LED panel 30 is mounted to the bracket frame. Generally, a pair of hanging pivot axles 35 extend from the LED panel 30, which engage to the mounting brackets. Pivot hooks 34 are mounted on a left and right side of the LED panel 30.

(12) The cover panel rests on a mounting bracket frame which includes a first mounting bracket 22 mounted parallel to a second mounting bracket 23, with a first mounting rail 24 parallel to a second mounting rail 25. The first mounting bracket fits above the right T-bar 26, and the second mounting bracket 23 mounts to the left T-bar 27. Similarly, the rear T-bar 28 supports the first mounting rail 24, and the front T-bar 29 supports the second mounting rail. The first mounting bracket 22 connects to the first mounting rail 24 which connects to the second mounting bracket 23 which connects to the second mounting rail 25, which connects to the first mounting bracket 22. Therefore, the mounting bracket frame is sandwiched between the cover panel and the T-bar frame.

(13) The LED panel 30 is mounted to the bracket frame. The LED panel 30 includes a panel lamp 32 powered by a power supply 31. A pair of pivot hook latches 33 have a pair of a pivot hooks 34 that engages to the mounting bracket frame at the first mounting bracket and the second mounting bracket.

(14) As seen in FIG. 2, the LED panel is installed to the mounting bracket frame at the panel pivot pin which allows the LED panel to swing freely in a detached position. The electrical connection from the power supply 31 to the cover panel 21 can be secured and then the LED panel 30 can be installed by rotating the LED panel from the vertical position to the horizontal position. The hanging pivot axles 35 can be formed as panel pivot pins 46 having panel pivot pin heads 48.

(15) As seen in FIG. 3, the LED panel 30 has a panel pivot pin 46 extending laterally from the LED panel 30. The panel pivot pin 46 is rigidly attached and has a preferably cylindrical body. The panel pivot pin 46 extends into a retainer slot 45. The retainer slot includes a panel pivot pin opening 47. The panel pivot pin 46 inserts into the panel pivot pin opening. The panel pivot pin has a panel pivot pin head 48 that has a larger diameter than the panel pivot pin body. The panel pivot pin head 48 enters the retainer slot 45 at the panel pivot pin opening 47 of the retainer slot 45 and slides downwardly to the retainer slot low side 49.

(16) The mounting bracket frame 40 has a mounting bracket main section 41 and a mounting bracket extension 141. The mounting bracket extension 141 extends at a 90° angle from the mounting bracket main section 41. The mounting bracket extension 141 has a connector to adjacent portions of the mounting bracket frame 40.

(17) The panel stop 43 is formed from the mounting bracket frame 40 at a fold in the bracket frame metal at a panel stop bend 42. The panel stop 43 can be cut from the mounting bracket frame 40 which creates a panel stop cut out 44. The panel stop cut out is an indented portion in the mounting bracket frame 40. The panel stop cut out is formed when the portion of material that is folded from the mounting bracket frame 40 forms the panel stop 43.

(18) The panel stop 43 preferably has a planar section with an upward extending lip. The panel stop abuts the upper surface of the LED panel 30 when the LED panel 30 is rotated to the engaged horizontal position from the disengaged vertical position. The panel stop cut out 44 is preferably rectangular and elongated. The panel stop cut out 44 and the panel stop bend 42 are parallel to the retainer slot 45.

(19) As seen in FIGS. 4 and 5, the LED panel 30 folds from a vertical position to a closed horizontal position. The T track frame is often called a T-bar frame 37 and can be existing structure. Also, the cover panel 21 can be existing structure to which the mounting bracket and LED panel are mounted to. The assembly begins by removing the existing lamps from the cover panel 21, then any ballast. The next step is to insert the bracket frame which includes the first mounting bracket 22 and the second mounting bracket 23. The mounting rails preferably have a tab and slot connection. After the mounting rails are inserted between the panel 21 and the T track frame, the LED panel 30 mounts to the mounting rails. The mounting brackets and mounting hole have an engagement which allows the user to first hang the LED panel 30 by inserting the panel pivot pin 46 into the panel pivot pin opening 47. The mounting brackets, mounting hole and panel connections to the mounting bracket frame are preferably all in the corners of the LED panel 30 on the left and right sides.

(20) As seen in FIGS. 6 and 7, the pivot hook latch 33 has a pivot hook body 50 which is preferably flat and terminates at a pivot hook handle 51. The pivot hook handle 51 extends at an angle from the pivot hook body 50. The pivot hook tip 52 passes through the panel stop latch opening 53 and engages to it. A retainer slot 45 with a panel pivot opening 47 and a retainer slot low side 49 is preferably formed next to the panel stop latch opening 43 to allow for reversibility of the installation. Preferably, the first mounting bracket 22, and the second mounting bracket 23 both have a pair of panel stop latch openings 53 and a pair of retainer slots 45. For example, the first mounting bracket 22 may have a first mounting bracket front panel stop latch opening 53, and a first mounting bracket rear panel stop latch opening 53. The second mounting bracket 23 have a second mounting bracket front panel stop latch opening 53 and a second mounting bracket rear panel stop latch opening 53. Also, the first mounting bracket may have a first mounting bracket front retainer slot, and a first mounting bracket rear retainer slot. The second mounting bracket may have a second mounting bracket front retainer slot and a second mounting bracket rear retainer slot.

(21) As seen in FIG. 8, the mounting brackets are U-shaped and have a pair of cutouts for the folded panel stops. The pivoting hook body 50 engages one of the folder panel stops. The U-shaped mounting bracket can be inserted first. The LED panel preferably has reversible installation, so that a user can remove the LED panel, rotate it 180° and reinstall it to the same bracket frame.
