Abstract

An apparatus for retrofitting a HID lighting system includes using existing components of previously installed HID lighting systems such as its ballasts while replacing some capacitors to adjust the power supplied to a retrofit LED luminaire. Unused ballast drivers are removed, and a self-contained ballast driver assembly is mounted into the electronic control enclosure of the previously installed lighting system. Some of the retrofit LED luminaires include an uplighting lens, an optic, or a diffuser for providing uplight. An aiming bracket and an aiming plate allow for the horizontal aiming angle of a light luminaire to be set.

First claim

What is claimed is:

1 . A self-contained ballast driver assembly comprising:
a circuit board; and an enclosure surrounding the circuit board, the enclosure including
a five-sided cover; and
a three-part mounting bracket;
wherein the five-sided cover includes a front panel defining a plurality of connector receiving windows, a top panel defining a plurality of vent openings, a bottom panel defining a plurality of vent apertures, a first side panel defining a plurality of first side apertures, and a second side panel defining a plurality of second side apertures.

2 . The self-contained ballast driver assembly of claim 1 , wherein the top panel includes a first pair of attachment flanges extending down from the top panel defining a first pair of attachment apertures, and the bottom panel includes a second pair of attachment flanges extending upwardly from the bottom panel defining a second pair of attachment apertures.

3 . The self-contained ballast driver assembly of claim 1 , wherein the top panel is connected to the front panel by a plurality of top bends.

4 . The self-contained ballast driver assembly of claim 3 , wherein each of the plurality of top bends are separated by a top cutout.

5 . The self-contained ballast driver assembly of claim 1 , wherein the bottom panel is connected to the front panel by a plurality of bottom bends.

6 . The self-contained ballast driver assembly of claim 5 , wherein each of the plurality of bottom bends are separated by a bottom cutout.

7 . The self-contained ballast driver assembly of claim 1 , wherein the three-part mounting bracket includes a first side circuit board mounting portion, a second side circuit board mounting portion, and a top enclosure attachment portion connecting the first side circuit board mounting portion to the second side circuit board mounting portion.

8 . The self-contained ballast driver assembly of claim 7 , wherein the first side circuit board mounting portion includes a first pair of cover mounting holes and a first pair of attachment flange receiving notches disposed proximate to the first pair of cover mounting holes, and the second side circuit board mounting portion includes a second pair of cover mounting holes and a second pair of attachment flange receiving notches disposed proximate to the second pair of cover mounting holes.

9 . The self-contained ballast driver assembly of claim 7 , wherein the top enclosure attachment portion includes an elongated aperture and is joined to the first side circuit board mounting portion by a first side bend, and the top enclosure attachment portion is joined to the second side circuit board mounting portion by a second side bend.

10 . The self-contained ballast driver assembly of claim 9 , wherein the first side bend is split by a first side cutout, and the second side bend is split by a second side cutout.

11 . The self-contained ballast driver assembly of claim 7 , wherein the first side circuit board mounting portion defines a first circuit board receiving slit, and the second side circuit board mounting portion defines a second circuit board receiving slit.

12 . The self-contained ballast driver assembly of claim 11 , wherein the first side circuit board mounting portion defines a first side heat sink receiving aperture, and the second side circuit board mounting portion defines a second side heat sink receiving aperture.

13 . The self-contained ballast driver assembly of claim 12 , wherein the first side heat sink receiving aperture is spaced away from the first circuit board receiving slit, and the second side heat sink receiving aperture is spaced away from the second circuit board receiving slit.

14 . The self-contained ballast driver assembly of claim 13 , wherein the first side circuit board mounting portion defines a third circuit board receiving slit that is in communication with the first side heat sink receiving aperture, and the second side circuit mounting portion defines a fourth circuit board receiving slit that is in communication with the second side heat sink receiving aperture.

15 . The self-contained ballast driver assembly of claim 13 , wherein the first side heat sink receiving aperture is L-shaped, and the second side heat sink receiving aperture is L-shaped.

16 . The self-contained ballast driver assembly of claim 13 , further including at least a first toe that is disposed beneath the first side heat sink receiving aperture.
