Abstract

Disclosure herein are aerodynamic surgical lights and methods of manufacturing and use thereof. The aerodynamic surgical lights may include a light head made of one or more substantially toroidal light housings. The substantially toroidal light housings contain and protect a plurality of LED lights and their respective reflectors that aim a light beam toward the lower side of the substantially toroidal light housings. The substantially toroidal light housings are vertically elongate. The vertically elongated substantially toroidal light housings include upper sections that are aerodynamically curved or pointed to streamline airflow past the light housings. The upper sections of the substantially toroidal light housings are made of molded plastic resin reinforced with carbon fibers or glass fibers and the lower sections of the substantially toroidal light housings are made of a clear moldable plastic.

First claim

What is claimed is:

1. An aerodynamic surgical light comprising:
a light head made of one or more substantially toroidal light housings; the one or more substantially toroidal light housings contain a plurality of LED lights and respective reflectors that aim a light beam toward a lower side of the one or more substantially toroidal light housings;
the one or more substantially toroidal light housings are vertically elongate in cross section with a vertical dimension at least 1.2 times greater than a horizontal width;
the one or more substantially toroidal light housings include upper sections that are aerodynamically curved or pointed in cross section to streamline airflow past the substantially toroidal light housing;
the aerodynamic curves include at least one of a substantially parabolic shape, a substantially pointed shape, a substantially semicircular shape, and combinations thereof;
the one or more substantially toroidal light housings are connected together to form a geographic center of mass where the one or more substantially toroidal light housings connect to a supporting boom system.

2. The aerodynamic surgical light of claim 1 , wherein the one or more substantially toroidal light housings are formed into one or more concentric substantially circular tubes with open spaces between the one or more concentric substantially circular tubes.

3. The aerodynamic surgical light of claim 2 , wherein the open spaces comprise greater than 30% of the projected surface area of the surgical light.

4. The aerodynamic surgical light of claim 2 , wherein the one or more substantially toroidal light housings form concentric substantially circular tubes with open spaces between the one or more concentric substantially circular tubes are connected together by spokes forming a wheel and spoke structure.

5. The aerodynamic surgical light of claim 4 , wherein a ball and socket joint and a light handle are connected to the center of the wheel and spoke structure.

6. The aerodynamic surgical light of claim 1 , wherein the plurality of LED lights and their respective reflectors in the one or more concentric substantially toroidal light housings are each mounted on axils that allow the reflector and light to pivot from a first position shining straight downward collectively creating a cylinder of light to a second position shining inward collectively creating a cone of light.

7. The aerodynamic surgical light of claim 6 , wherein the adjacent axils of the adjacent lights are coupled to each other through flexible couplings allowing the positioning of one or more lights to dictate the position of all of the lights in each substantially toroidal light housing.

8. The aerodynamic surgical light of claim 7 , wherein the flexible couplings include ball-shaped Allen wrench heads and sockets, cables, U joints or lock and key connectors.

9. The aerodynamic surgical light of claim 1 , wherein the upper sections of the one or more substantially toroidal light housings are made of plastic resin reinforced with carbon fibers or glass fibers and the lower sections of the one or more substantially toroidal light housings are made of a clear plastic.

10. An aerodynamic surgical light comprising:
a light head made of one or more substantially toroidal light housings; the one or more substantially toroidal light housings contain a plurality of LED lights and respective reflectors that aim a light beam toward a lower side of the one or more substantially toroidal light housings;
the one or more substantially toroidal light housings are vertically elongate in cross section with a vertical dimension at least 1.2 times greater than the horizontal width;
the one or more substantially toroidal light housings include upper sections that are aerodynamically curved or pointed in cross section to streamline airflow past the light housing;
the aerodynamic curves include at least one of substantially parabolic shapes, substantially pointed shapes, substantially semicircular shapes, and combinations thereof;
the one or more substantially toroidal light housings are formed into one or more concentric substantially circular tubes with open spaces between the one or more concentric substantially circular tubes;
wherein the open spaces comprise greater than 30% of the projected surface area of the surgical light.

11. The aerodynamic surgical light of claim 10 , wherein the one or more substantially toroidal light housings form concentric substantially circular tubes with open spaces between the one or more concentric substantially circular tubes are connected together by spokes forming a wheel and spoke structure.

12. The aerodynamic surgical light of claim 11 , wherein the one or more substantially toroidal light housings are connected together to form a geographic center of mass where the substantially toroidal light housings connect to a supporting boom system.

13. The aerodynamic surgical light of claim 12 , wherein a ball and socket joint and a light handle are connected to the center of the wheel and spoke structure.

14. The aerodynamic surgical light of claim 10 , wherein the plurality of LED lights and their respective reflectors in the one or more concentric substantially toroidal light housings are each mounted on axils that allow the reflector and light to pivot from a first position shining straight downward collectively creating a cylinder of light to a second position shining inward collectively creating a cone of light.

15. The aerodynamic surgical light of claim 14 , wherein the adjacent axils of the adjacent lights are coupled to each other through flexible couplings allowing the positioning of one or more lights to dictate the position of all of the lights in each substantially toroidal light housing.

16. The aerodynamic surgical light of claim 15 , wherein the flexible couplings include ball-shaped Allen wrench heads and sockets, cables, U joints or lock and key connectors.

17. The aerodynamic surgical light of claim 10 , wherein the upper sections of the one or more substantially toroidal light housings are made of plastic resin reinforced with carbon fibers or glass fibers and the lower sections of the one or more substantially toroidal light housings are made of a clear plastic.

18. An aerodynamic surgical light comprising:
a light head made of one or more substantially toroidal light housings;
the one or more substantially toroidal light housings contain and protect a plurality of LED lights and respective reflectors that aim a light beam toward the lower side of the substantially toroidal light housings;
the substantially toroidal light housings are vertically elongate in cross section with a vertical dimension at least 1.2 times the horizontal width;
the one or more substantially toroidal light housings include upper sections that are aerodynamically curved or pointed in cross section to streamline airflow past the light housing;
the aerodynamic curves include at least one of substantially parabolic shapes, substantially pointed shapes, substantially semicircular shapes, and combinations thereof;
the one or more substantially toroidal light housings are formed into one or more concentric substantially circular tubes with open spaces between the one or more concentric substantially circular tubes;
wherein the one or more concentric substantially circular tubes with open spaces between the one or more concentric substantially circular tubes are connected together by spokes forming a wheel and spoke structure.
