Abstract

A lighting system and method are disclosed. Specifically, the lighting system includes a hybrid canopy that can provide an optimum light beam shape for a number of different lighting applications. The hybrid canopy is equipped with lighting clusters of different types, thereby enabling a broader beam output without sacrificing beam intensity or brightness.

Claims

1. A lighting system, comprising:

a hybrid lighting canopy that includes;

a Printed Circuit Board (PCB) having a plurality of light sources connected thereto;

a first reflector cup cluster having a first set of reflector cups, the first reflector cup cluster positioned relative to a first surface of the PCB so that each reflector cup in the first set of reflector cups surrounds a light source in a first set of light sources from the plurality of light sources; and

a second reflector cup cluster having a second set of reflector cups, the second reflector cup cluster positioned relative to the first surface of the PCB so that each reflector cup in the second set of reflector cups surrounds a light source in a second set of light sources from the plurality of light sources, wherein the first set of light sources is different from the second set of light sources, and wherein the first reflector cup cluster comprises at least one light-directing property that is different from the second reflector cup cluster.

2. The system of claim 1, wherein at least one reflector cup in the first set of reflector cups comprises at least one of a different shape and different size than at least one reflector cup in the second set of reflector cups.

3. The system of claim 1, wherein at least one reflector cup in the first set of reflector cups comprises a different reflectivity than at least one reflector cup in the second set of reflector cups.

4. The system of claim 1, wherein at least one reflector cup in the first set of reflector cups comprises a different lens than at least one reflector cup in the second set of reflector cups.

5. The system of claim 4, wherein the at least one reflector cup in the first set of reflector cups comprises a lens made of a first material and wherein the at least one reflector cup in the second set of reflector cups comprises a lens made of a second material that is different from the first material.

6. The system of claim 4, wherein the at least one reflector cup in the first set of reflector cups comprises a lens having a first shape and wherein the at least one reflector cup in the second set of reflector cups comprises a lens having a second shape.

7. The system of claim 1, wherein the first set of reflector cups comprises narrow-angle reflector cups and wherein the second set of reflector cups comprises wide-angle reflector cups.

8. The system of claim 1, wherein the first set of reflector cups comprises both a first type of reflector cup and a second type of reflector cup that is different from the first type of reflector cup by at least one of size, shape, height, depth, reflectivity, and coating material.

9. The system of claim 1, wherein the first reflector cup cluster is modular and removable from the PCB.

10. A hybrid lighting canopy, comprising:

a first lighting cluster having a first set of reflector cups, each of which are positioned around a light source from a first set of light sources, respectively;

a second lighting cluster having a first set of reflector cups, each of which are positioned around a light source from a second set of light sources, respectively; and

wherein the first set of reflector cups comprise at least one light-directing property that is different from the second set of reflector cups.

11. The lighting canopy of claim 10, wherein the first set of reflector cups comprise a first shape, wherein the second set of reflector cups comprise a second shape, and wherein the first shape is different from the second shape.

12. The lighting canopy of claim 11, wherein the first set of reflector cups produce a narrow-angle beam of light and wherein the second set of reflector cups produce a wide-angle beam of light.

13. The lighting canopy of claim 11, wherein the first shape is round and the second shape is rectangular.

14. The lighting canopy of claim 10, wherein the first set of reflector cups comprise a first size, wherein the second set of reflector cups comprise a second size, and wherein the first size is different from the second size.

15. The lighting canopy of claim 10, wherein the first set of reflector cups comprise a first reflectivity and wherein the second set of reflector cups comprise a second reflectivity that is different from the first reflectivity.

16. The lighting canopy of claim 10, further comprising:

a third lighting cluster having a third set of reflector cups, each of which are positioned around a light source from a third set of light sources, respectively; and

wherein the third set of reflector cups comprise at least one light-directing property that is different from the first and second set of reflector cups.

17. A lighting cluster for use in a lighting canopy, the lighting cluster comprising:

a first reflector cup, the first reflector cup being of a first type and comprising a first set of light-directing properties; and

a second reflector cup, the second reflector cup being of a second type and comprising a second set of light-directing properties, the first set of light-directing properties being different than the second set of light-directing properties.

18. The lighting cluster of claim 17, wherein the first and second reflector cups are established in a single piece of material as separate indentions.

19. The lighting cluster of claim 17, wherein the first reflector cup comprises at least one of a different shape, size, reflectivity, height, and depth than the second reflector cup.

20. The lighting cluster of claim 17, further comprising:

a third reflector cup, the third reflector cup being of a third type and comprising a third set of light-directing properties that is different from the first and second set of light-directing properties, wherein the first, second, and third reflector cups are established in a single piece of material as separate indentions, and wherein the third reflector cup comprises at least one of a different shape, size, reflectivity, height, and depth than the first and second reflector cups.
