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 lighting system comprising:
a first crossarm member; a first aiming bracket; and a first aiming plate disposed between the first crossarm member and the first aiming bracket; wherein the first aiming bracket includes a periphery and a plurality of angle markings disposed at least partially about the periphery of the first aiming bracket and the first aiming plate includes a first angle indicator that extends to the periphery of the first aiming bracket.

2 . The lighting system of claim 1 , wherein the first crossarm member is an auxiliary crossarm.

3 . The lighting system of claim 1 , further comprising a first knuckle attached to the first aiming bracket.

4 . The lighting system of claim 3 , wherein the first knuckle includes a lower electrical receptable portion, and an upper knuckle portion that is rotatably attached to the lower electrical receptable portion about a first axis.

5 . The lighting system of claim 4 , wherein the upper knuckle portion of the first knuckle is in fixed relation to the first aiming bracket about a second axis that is perpendicular to the first axis.

6 . The lighting system of claim 5 , wherein the first aiming bracket, and the upper knuckle portion of the first knuckle are rotatable about the second axis relative to the first crossarm member.

7 . The lighting system of claim 1 , wherein the periphery includes a front flat portion, and the first angle indicator extends to the front flat portion of the first aiming bracket.

8 . The lighting system of claim 1 , wherein the first crossarm member defines a round swivel aperture defining an axis of rotation, and a first mounting aperture disposed away from the round swivel aperture about the axis of rotation.

9 . The lighting system of claim 8 , further defining a second mounting aperture disposed about the axis of rotation, forming a circular array with the first mounting aperture about the axis of rotation.

10 . The lighting system of claim 9 , further defining a third mounting aperture, and a fourth mounting aperture defining a rectangular pattern centered about the axis of rotation along with the first and the second mounting apertures.

11 . The lighting system of claim 10 , wherein the rectangular pattern is a square pattern.

12 . The lighting system of claim 1 , wherein the first aiming plate defines a pair of parallel sides that are flush to recessed relative to a pair of side surfaces of the first crossarm member.
