Abstract

An anti bird-perch lighting system for use with a facility that includes a plurality of dome-shaped light collectors disposed on a rooftop of the facility, with a projection extending from an apex of the light collector, and at least one filament extending from substantially all of the projections so that each projection is connected to two or more of the other projections to define a filament network disposed above the roof and proximate a top of the plurality of light collectors.

Claims

1. An anti bird-perch lighting system for use with a facility, the system comprising:

a plurality of light pipes, each having a substantially dome-shaped light collector;

a projection extending from the light collector; and

at least one filament extending between two or more of the projections to define a filament network.

2. The system of claim 1, wherein the projection extends from an apex of the light collector.

3. The system of claim 2, wherein the light collectors are disposed on a roof of the facility.

4. The system of claim 3, wherein the filament comprises a substantially clear monofilament material.

5. The system of claim 3, wherein each projection is connected to at least two other projections by the filament.

6. The system of claim 5, wherein each projection is connected to each of the other projections by the filament.

7. The system of claim 6, wherein the filament is a continuous filament.

8. The system of claim 1, further comprising a tensioning device configured to maintain a desired taughtness of the filament network.

9. The system of claim 1, wherein the filament network comprises a contoured topography.

10. An anti bird-perch lighting system for use with a facility, the system comprising:

a plurality of dome-shaped light collectors disposed on a rooftop of the facility;

a projection extending from an apex of the light collector; and

at least one substantially clear filament connected to two or more of the projections to define a filament network disposed above the rooftop and proximate a top of the plurality of light collectors.

11. The system of claim 10, wherein the filament network comprises a topography that is substantially planar.

12. The system of claim 10, wherein the filament network defines a pattern of filaments that is asymmetric.

13. The system of claim 10, further comprising one or more objects suspended from a filament at a location between two light collectors.

14. An anti bird-perch lighting system for use with a facility having a rooftop, the system comprising:

a plurality of light collectors disposed on the rooftop of the facility and configured to collect sunlight;

a projection extending from each of the light collectors; and

a filament interconnecting the projections on the light collectors to define a filament network disposed above the rooftop and proximate a top of the plurality of light collectors.

15. The system of claim 14, wherein the light collectors comprise dome-shaped covers for a light pipe device.

16. The system of claim 14, wherein the projections comprise a retention feature configured to retain the filament in connection with the projection.

17. The system of claim 14, wherein the filament comprises a substantially transparent material.

18. The system of claim 14, wherein the filament network comprises a non-planar topography.
