Abstract

A lighting system utilizing light emitting diode lamps, designed to be mounted on the mullion inside a cabinet display case wherein the distribution of light illuminates the product in an even and consistent manner.

Claims

1. A lighting system comprising:

a base;

an end cap;

a printed circuit board including;

a plurality of light emitting diodes; and

a bezel; and

a plurality of lenses held in place by the bezel, a lens for each of the plurality of light emitting diodes, each lens disposed in the bezel in relation to its respective light emitting diode to provide a light output pattern wherein the highest intensities of light are directed at substantially right and left angles to said base.

2. The lighting system of claim 1 wherein the base comprises a means for mounting.

3. The lighting system of claim 2 wherein the base includes a mount engaging channel.

4. The lighting system of claim 3 further comprising a medial mount comprising:

a tension clip; and

a bias leaf that engages the mount engaging channel.

5. The lighting system of claim 1 wherein the end cap includes a means for mounting.

6. The lighting system of claim 5 wherein the mounting means comprises a mounting flange.

7. The lighting system of claim 1 wherein the printed circuit board includes circuit connectors.

8. The lighting system of claim 7 wherein the circuit connectors comprise a pluggable connector.

9. The lighting system of claim 1 including a conduit plug for passing electrical conductors to the printed circuit board.

10. The lighting system of claim 9 wherein the conduit plug comprises a pluggable connector.

11. The lighting system of claim 7 wherein the printed circuit board includes a plurality of circuit connectors.

12. The lighting system of claim 1 wherein the printed circuit board comprises a pass through circuit that allows a second lighting system to be electrically connected in tandem.

13. The lighting system of claim 1 wherein said light output pattern of each light emitting diode is directed at substantially 70 degree to 90 degree angle left and right to said base.

14. The lighting system of claim 13 wherein the base includes a bezel retaining channel.

15. The lighting system of claim 1 wherein the bezel includes contouring to nest with the printed circuit board in a manner to provide relative placement of each light emitting diode and its respective lens.

16. The lighting system of claim 1 wherein the bezel includes contouring to interlock with the printed circuit board in a manner to provide proper relative placement of each light emitting diode and its respective lens.

17. The lighting system of claim 1 wherein the printed circuit board fits within a trough of the base in a manner to provide proper relative placement of each light emitting diode and its respective lens.

18. The lighting system of claim 1 disposed within a cabinet display case.

19. The lighting system of claim 18 mounted to the mullion in a manner as to provide even and consistent light to the product therein.

20. A lighting system mounted to the mullion within a cabinet display case comprising:

a base comprising

a mounting engaging channel and

a bezel retaining channel;

an end cap comprising

a mounting flange and

a conductor throughput;

a printed circuit board comprising

a plurality of light emitting diodes,

a circuit connector, and

a pass through circuit;

a bezel; and

a plurality of lenses held in place by the bezel, a lens for each of the plurality of light emitting diodes, each lens disposed in the bezel in relation to its respective light emitting diode to provide a light output pattern wherein the highest intensities of light is directed at angles from 70 degrees to 90 degrees right and left of said base, and

wherein the bezel is contoured to provide proper relative placement of each light emitting diode to its respective lens.
