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.

First claim

We claim:

1. A lighting assembly for a merchandise display comprising:
a lighting bar;
a circuit board assembly having a plurality of LEDs mounted to the lighting bar, wherein the plurality of LEDs project a light onto a merchandise display;
a plurality of lenses covering certain of the plurality of LEDs, and wherein the lenses capture the light from their respective LEDs, modify a beam pattern emitted from their respective LED, and re-project the light emitted from the plurality of LEDs in a substantially even distribution vertically and wherein the plurality of lenses each individually fit over their respective LEDs and comprise two different lens types;
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 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 two different lens types comprise different configurations that produce a spotlight beam pattern and an oval shaped beam pattern, such that the lenses producing the spotlight beam pattern are directed toward a bottom shelf of the merchandise display and the lenses producing the oval shaped beam pattern are directed at an upper area and a middle area of the merchandise display.

2. The lighting assembly of claim 1 , wherein the lighting bar is configured to adjust the orientation of the plurality of LEDs mounted to the inside of the lighting bar.

3. The lighting assembly of claim 1 , wherein the two different lens types are placed over the LEDs in an alternating pattern, and the alternating pattern of the plurality of lenses emit light from the lighting bar that covers the entire merchandise display, from a top shelf to a bottom shelf.

4. The lighting assembly of claim 1 , wherein the plurality of lenses is arranged such that every other LED on the lighting bar is covered by a lens.

5. The lighting assembly of claim 1 , wherein the LEDs are aligned in a substantially straight line.

6. The lighting assembly of claim 1 , wherein the lenses are secured with a snap fit connection.

7. A merchandise display lighting method comprising:
arranging a plurality of LEDs on a circuit board located within a lighting bar, wherein the plurality of LEDs project a light onto a merchandise display;
securing a plurality of lenses to the circuit board;
placing the plurality of lenses over every other LED on the lighting bar so as to capture the light from a respective LED, modify a beam pattern emitted from the respective LED, and re-project the light emitted from the respective LED; and
providing two different lens types in the plurality of lenses and placing the two different lens types over the LEDs in an alternating pattern;
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 beams include a first light beam in a first direction and a second light beam in a second direction different than the first direction;
wherein the two different lens types comprise different configurations that produce a spotlight beam pattern and an oval shaped beam pattern, such that the lenses producing the spotlight beam pattern are directed toward a bottom shelf of the merchandise display and the lenses producing the oval shaped beam pattern are directed at an upper area and a middle area of the merchandise display; and
wherein every other LED on the lighting bar is uncovered.

8. The merchandise display lighting method of claim 7 , further comprising adjusting the beam patterns with the lighting bar.

9. The merchandise display lighting method of claim 7 , wherein the plurality of lenses are secured with a snap fit connection.

10. The merchandise display lighting method of claim 7 , further comprising aligning the plurality of LEDs in a substantially straight line.

11. An LED lighting system for a merchandise display comprising:
a lighting bar;
a circuit board assembly having a plurality of LEDs mounted to the lighting bar, wherein the plurality of LEDs projects a light onto a merchandise display;
a plurality of lenses individually secured to the circuit board assembly, and
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 beams include a first light beam in a first direction and a second light beam in a second direction different than the first direction;
wherein the lenses capture the light from a respective LED, modify a beam pattern emitted from the respective LED, and re-project the light emitted from the plurality of LEDs in a substantially even distribution vertically, wherein the plurality of lenses comprise two different lens types and the two different lens types are placed over the LEDs in an alternating pattern; and
wherein the two different lens types comprise different configurations that produce a spotlight beam pattern and an oval shaped beam pattern, such that the lenses producing the spotlight beam pattern are directed toward a bottom shelf of the merchandise display and the lenses producing the oval shaped beam pattern are directed at an upper area and a middle area of the merchandise display.

12. The LED lighting system of claim 11 , wherein the plurality of lenses is secured with a snap fit connection.

13. The LED lighting system of claim 11 , wherein the lighting bar is adjustable and directs and aims light emitted from the plurality of LEDs.

14. The merchandise display lighting method of claim 7 , wherein the plurality of reflective surfaces are curved mirrors.

15. The lighting assembly of claim 1 , wherein the plurality of reflective surfaces are curved mirrors.

16. The LED lighting system of claim 11 , wherein the plurality of reflective surfaces are curved mirrors.
