Abstract

A lighting system (100) including a plurality of LED-based light sources (102), where each of the light sources includes an optic holder (210) with an upper edge region (260). The arrangement of the optic holders within the lighting system results in gaps (220) between neighboring optic holders. The system includes a plurality of interstitial spacers (310) manufactured on or attached to the upper edge region of the optic holders, such that the interstitial spacers are arranged to substantially fill the one or more gaps.

Claims

1. A lighting system comprising:

a plurality of LED-based light sources;

a plurality of optic holders, each of which is connected to a respective one of said plurality of LED-based light sources and is arranged to hold an optic in a position suitable to modify light emitted by said LED-based light source, each of the plurality of optic holders comprising an upper edge region, wherein said arrangement results in one or more gaps between one or more optic holders; and

a plurality of interstitial spacers connected to the upper edge region of the plurality of optic holders, wherein the plurality of interstitial spacers are arranged to substantially fill the one or more gaps, wherein at least one of said plurality of interstitial spacers is adjustable.

2. The lighting system of claim 1, wherein each of the plurality of interstitial spacers are of substantially the same shape.

3. The lighting system of claim 1, wherein each of the plurality of interstitial spacers are of substantially the same size.

4. The lighting system of claim 1, wherein at least one of said plurality of interstitial spacers is configured to removably attach to the upper edge region of one of said plurality of optic holders.

5. The lighting system of claim 1, wherein the plurality of optic holders and the plurality of interstitial spacers are substantially the same color.

7. The lighting system of claim 5, wherein the size of the at least one of said plurality of interstitial spacers is adjustable.

8. The lighting system of claim 5, wherein the shape of the at least one of said plurality of interstitial spacers is adjustable.

9. The lighting system of claim 1, further comprising a light source holder, wherein each of said plurality of LED-based light sources are connected to the light source holder, and further wherein at least a portion of said light source holder is visible through said gaps.

10. The lighting system of claim 8, wherein said plurality of interstitial spacers are arranged along the upper edge region of the plurality of optic holders to obscure said light source holder.

6. (canceled)

11. An optic holder system, the optic holder comprising:

an optic; and

one or more interstitial spacers connected to an upper edge region of the optic holder.

12. The optic holder system of claim 11, wherein at least one of the interstitial spacers is configured to removably attach to the upper edge region of the optic holder.

13. The optic holder system of claim 11, wherein the one or more interstitial spacers are adjustable.

14. The optic holder system of claim 13, wherein the size of the at least one of said plurality of interstitial spacers is adjustable.

15. The optic holder system of claim 13, wherein the shape of the at least one of said plurality of interstitial spacers is adjustable.

16. A method for generating a lighting system, the method comprising the steps of:

providing a lighting system comprising;

(i) a plurality of LED-based light sources;

(ii) a plurality of optic holders each of which is connected to a respective one of said plurality of LED-based light sources and is arranged to hold an optic in a position suitable to modify light emitted by said LED-based light source, each of the plurality of optic holders comprising an upper edge region, wherein said arrangement results in one or more gaps between one or more optic holders; and

providing a plurality of interstitial spacers connected to the upper edge region of the plurality of optic holders, wherein the plurality of interstitial spacers are arranged to substantially fill the one or more gaps

further comprising the step of adjusting one or more of the interstitial spacers to substantially fill the one or more gaps.
