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 LED luminaire comprising:
a fixture defining a fixture perimeter with a horizontal width, and a vertical height;
a front fixture frame defining a window opening perimeter, and a plurality of light sources disposed within the window opening perimeter, the plurality of light sources including a rectangular array of LEDs including a series of top rows,
a visor that is attached to the front fixture frame and a lens, an optic, or a diffuser attached to a free end of the visor,
wherein a ratio of the horizontal width to the vertical height ranges from 0.90 to 1.25 allowing the LED luminaire to fit within a footprint of a previously installed HID lamp, the plurality of light sources is spaced a maximum vertical distance from the fixture perimeter that is greater than any other vertical distance from the fixture perimeter to the plurality of light sources, and a ratio of the vertical height of the fixture perimeter to the maximum vertical distance ranges from 1.85 to 2.24 allowing the LED luminaire to fit within the footprint of the previously installed HID lamp and place any LEDs of the LED luminaire low enough so there is little to no photometric interference with other LED luminaires when installed, and the lens, the optic, or the diffuser vertically covers 0% to 40% of the series of top rows of the rectangular array of LEDs when the LED array is vertically oriented.

2. The LED luminaire of claim 1 , wherein the ratio of the horizontal width to the vertical height ranges from 0.97 to 1.17.

3. The LED luminaire of claim 1 , wherein the horizontal width ranges from 14.0 inches to 15.5 inches, and the vertical height ranges from 11.0 inches to 13.0 inches.

4. The LED luminaire of claim 1 , wherein the fixture perimeter is rectangularly shaped.

5. The LED luminaire of claim 1 , further comprising an array of quad wide beam LEDs including 4 horizontally extending rows and 15 vertically extending rows.

6. The LED luminaire of claim 1 , wherein the visor includes a top surface that forms a top angle with a horizontal plane that ranges from 10.0 degrees to 20.0 degrees.

7. The LED luminaire of claim 1 , wherein the visor extends a horizontal projection distance that is perpendicular to the horizontal width, and vertical height of the fixture, and a ratio of the horizontal projection distance to the vertical height ranges from 0.96 to 2.07.

8. The LED luminaire of claim 7 , wherein the ratio of the horizontal projection distance to the vertical height ranges from 1.05 to 1.90.

9. The LED luminaire of claim 1 , wherein the lens, the optic, or the diffuser vertically covers 30% to 40% of the series of top rows of the rectangular array of LEDs when the LED array is vertically oriented.

10. The LED luminaire of claim 1 , wherein the visor includes a front panel with a plurality of mounting apertures.

11. The LED luminaire of claim 10 , wherein the lens, the optic, or the diffuser includes a plurality of mounting holes that are configured to align with the plurality of the mounting apertures.

12. The LED luminaire of claim 1 , further comprising a fixture backplate, and a front fixture frame attached to the fixture backplate.

13. The LED luminaire of claim 12 , further comprising a knuckle and a heat sink that are attached to the fixture backplate.

14. The LED luminaire of claim 12 , wherein the front fixture frame defines a window that is configured to receive an exterior lens.

15. The LED luminaire of claim 14 , further comprising a LED plate with a plurality of LEDs that is attached to the fixture backplate, an optics holder with a plurality of apertures disposed about the LEDs, an optics plate disposed in the optics holder adjacent the LED plate.

16. The LED luminaire of claim 1 , wherein the vertical maximum distance is disposed vertically above the plurality of light sources between the plurality of light sources and the visor.
