Abstract

Aspects of the disclosure relate to a lighting assembly and method for illuminating a vertical planar area, such as a merchandise display. The lighting assembly can comprise two opposing support arms and a lighting bar extending between the two opposing support arms, a circuit board having a plurality of LEDs mounted to the inside of the lighting bar; and a plurality of reflective surfaces located adjacent to the plurality of LEDs, wherein the plurality of reflective surfaces are positioned such that the LEDs project a first light beam in a first direction and a second light beam in a second direction different than the first direction.

Claims

1. A lighting assembly for a merchandise display comprising:

a lighting bar positioned above the merchandise display;

a circuit board assembly having a plurality of LEDs mounted to the inside of the lighting bar, wherein the plurality of LEDs are spaced apart from each other and project a light onto the merchandise display;

a plurality of lenses, wherein each lens of the plurality of lenses is placed over every other LED of the plurality of LEDs, wherein every other LED of the plurality of LEDs is uncovered;

wherein each lens of the plurality of lenses captures the light from a corresponding LED, modifies a beam pattern emitted from the corresponding LED, and re-projects the light emitted from the corresponding LED;

a plurality of reflective surfaces, wherein the plurality of reflective surfaces are positioned adjacent to the plurality of LEDs, wherein the plurality of reflective surfaces divide the light thereby creating multiple light beams projecting from the LEDs, wherein the multiple light beams include a first light beam in a first direction and a second light beam in a second direction different than the first direction; and

wherein the light from the plurality of LEDs projects in a substantially even distribution over a vertical plane in front of the merchandise display.

2. The lighting assembly for a merchandise display of claim 1, wherein the lighting bar rotates about a horizontal axis to adjust a direction of the light from the plurality of LEDs.

3. The lighting assembly for a merchandise display of claim 1, wherein at least one of the plurality of lenses provides a different beam pattern than another one of the plurality of lenses.

4. The lighting assembly for a merchandise display of claim 1, wherein the plurality of lenses comprises two different lens types and the two different lens types are placed over the plurality of LEDs in an alternating pattern.

5. The lighting assembly for a merchandise display of claim 4, wherein the two different lens types comprise different configurations that produce a spotlight beam pattern and an oval shaped beam pattern.

6. The lighting assembly for a merchandise display of claim 5, wherein the spotlight beam pattern is directed toward a lower area of the merchandise display and the oval shaped beam pattern is directed toward an upper area of the merchandise display.

7. The lighting assembly for a merchandise display of claim 1, wherein the plurality of LEDs are aligned in a substantially straight line.

8. A method for lighting a merchandise display comprising:

arranging a plurality of LEDs on a circuit board assembly located within a lighting bar, wherein the lighting bar is positioned above the merchandise display and the plurality of LEDs project a light onto the merchandise display;

securing a plurality of lenses individually over a respective LED of the plurality of LEDs to the circuit board assembly, wherein the plurality of lenses comprises two different lens types;

placing each lens of the plurality of lenses over every other LED of the plurality of LEDs such that every other LED on the lighting bar is uncovered so as to capture the light from the respective LED, modify a beam pattern emitted from the respective LED, and re-project the light emitted from the respective LED,

securing a plurality of reflective surfaces adjacent to the plurality of LEDs, wherein the plurality of reflective surfaces divide the light thereby creating multiple light beams projecting from the LEDs, wherein the multiple light beams include a first light beam in a first direction and a second light beam in a second direction different than the first direction; and

wherein the light from the plurality of LEDs projects in a substantially even distribution over an upper area and a lower area of the merchandise display.

9. The method for lighting a merchandise display of claim 8, further comprising adjusting a direction of the beam pattern by rotating the lighting bar around a horizontal axis of the lighting bar.

10. The method for lighting a merchandise display of claim 8, further comprising placing the two different lens types over the plurality of LEDs in an alternating pattern.

11. The method for lighting a merchandise display of claim 8, wherein the two different lens types comprise different configurations that produce a spotlight beam pattern and an oval shaped beam pattern.

12. The method for lighting a merchandise display of claim 8, further comprising aligning the plurality of LEDs in a substantially straight line.

13. A lighting system for a merchandise display comprising:

a lighting bar positioned above the merchandise display;

a circuit board assembly having a plurality of LEDs mounted to the inside of the lighting bar, wherein the plurality of LEDs project a light onto the merchandise display; and

a plurality of lenses spaced apart from one another and arranged in a substantially straight line, wherein each lens of the plurality of lenses is individually placed around each of the plurality of LEDs on the lighting bar,

wherein the plurality of lenses consists of two different lens types, wherein a first lens type produces a spotlight beam pattern and a second lens type produces an oval shaped beam pattern, wherein the first lens type and the second lens type are placed over the plurality of LEDs in a pattern where the plurality of lenses alternate between the first lens type and the second lens type;

wherein each lens of the plurality of lenses captures the light from respective LEDs, modifies the light emitted from the respective LEDs, and re-projects the light emitted from the plurality of LEDs; and

a plurality of reflective surfaces positioned adjacent to the plurality of LEDs, wherein the plurality of reflective surfaces divide the light thereby creating multiple light beams projecting from the LEDs, wherein the multiple light beams include a first light beam in a first direction and a second light beam in a second direction different than the first direction.

14. The lighting system for a merchandise display of claim 13, wherein the lighting bar is adjustable about a horizontal axis to direct the light emitted from the plurality of LEDs.

15. The lighting system for a merchandise display of claim 13, further comprising aligning the plurality of LEDs in a substantially straight line.

16. The lighting system for a merchandise display of claim 13, wherein the plurality of lenses are secured to the circuit board assembly with a snap-fit connection.
